How Bicycles Can Revolutionize Our Lives: Case Studies from the United States, Netherlands, China & Britain

A two- (and three- and one-) wheeled rev­o­lu­tion is upon us. Dubbed “micro-mobil­i­ty” by start-up mar­keters and influ­encers, the trend incor­po­rates all sorts of per­son­al means of trans­port. While the buzz may hov­er around elec­tric scoot­ers and skate­boards, the faith­ful bicy­cle still leads the pack, as it has for over a hun­dred years. And advocates—who bike as their pri­ma­ry means of exer­cise, com­mut­ing, and run­ning dai­ly errands—are chal­leng­ing the ortho­dox­ies of car cul­ture.

As an avid cyclist myself, who bikes as often as I can for gro­ceries and oth­er errands, I will admit to a strong bias in their favor. But even I’ve been chal­lenged and sur­prised by what I’ve learned from bik­ing advo­cates like Liz Can­ning, pro­duc­er and nar­ra­tor of a new doc­u­men­tary film, Moth­er­load, a por­trait of the many peo­ple who have cho­sen to use car­go bikes instead of cars for near­ly every­thing.

The film is remark­able for the ordi­nar­i­ness of its sub­jects. As one car­go cyclist, Brent Pat­ter­son of Buf­fa­lo, New York, says, “I’m not an ath­lete. I’m not super­hu­man. I’m just a com­plete­ly nor­mal per­son like you.” The Pat­ter­son fam­i­ly “sold its car,” notes Out­side mag­a­zine, “and trav­els by car­go bike year-round, even in snow­storms.” Anoth­er car­go cyclist in the film, Emi­ly Finch, “carts all six of her kid­dos around on two wheels.” We see car­go cyclists around the world, using bikes as emer­gency trans­port haulers and dai­ly gro­cery-get­ters.

Most of the Amer­i­cans pro­filed live in bike-friend­ly com­mu­ni­ties like Marin Coun­ty, Cal­i­for­nia or Port­land, Ore­gon. But oth­ers, like the Pat­ter­sons, do not, “and not all are as com­fort­ably off as Can­ning,” who retired as a com­mer­cial film­mak­er to raise her kids in bike-friend­ly Fair­fax, CA. “Some had to sell their car or take out a no-inter­est loan in order to afford a car­go bike.” No one seems to have regret­ted the deci­sion.

Read­ers who hail from, or have lived in, places in the world where bike-reliance is the norm may scoff at the pre­sumed nov­el­ty of the idea in Canning’s film. But at one time, even the Netherlands—home of the ubiq­ui­tous Bak­fi­ets—was almost as car-cen­tric as most of the U.S., as Amer­i­can Dan Kois writes in a New York­er essay about how he learned to become bike com­muter in the Nether­lands.

I had assumed that Dutch people’s adept­ness at bik­ing was the result of gen­er­a­tions of inces­sant cycling. In fact, after the Sec­ond World War, the Nether­lands had, like the U.S., become dom­i­nat­ed by cars. Cycling paths were over­tak­en by roads, and neigh­bor­hoods in Ams­ter­dam were razed to make room for high­ways. Between 1950 and 1970, the num­ber of cars in the coun­try explod­ed from about a hun­dred thou­sand to near­ly two and a half mil­lion. Dur­ing that same peri­od, bike use plum­met­ed; in Ams­ter­dam, the per­cent­age of trips made by bike fell from eighty to twen­ty.

That all changed when young activists and par­ents, espe­cial­ly mothers—like the bik­ing moth­ers in Moth­er­load—began protest­ing high num­bers of traf­fic deaths. They took to the streets on their bikes, block­ing traf­fic, run­ning for office, and pres­sur­ing city offi­cials to make infra­struc­ture and pub­lic space safe and accom­mo­dat­ing for bikes. Now, there are more bikes than peo­ple in the Nether­lands, and cars co-exist on roads full of cyclists of all ages and class­es, on their way to work, school, and every­where else.

Dutch dri­vers “look out for cyclists,” writes Kois. “After all, near­ly all of those dri­vers are cyclists them­selves,” using the car for a brief, nec­es­sary out­ing before they get back on their bikes for most every­thing else. Next to Kois’ first-per­son account of his few-months-long sojourn through Delft, we have the glob­al tes­ti­mo­ny of the Bicy­cle Archi­tec­ture Bien­nale, a “show­case of cut­ting edge and high pro­file build­ing designs that are facil­i­tat­ing bicy­cle trav­el and trans­form­ing com­mu­ni­ties around the world.” The exhibits, writes Karen Wong at David Byrne’s Rea­sons to Be Cheer­ful, “point the way to a two-wheeled utopia.”

BYCS, the group respon­si­ble for this well-curat­ed exhi­bi­tion, come from Ams­ter­dam. The projects they fea­ture, how­ev­er, are in Lon­don and Chong­min and Cheng­du, Chi­na. The car­go cyclists in Moth­er­load, and the fero­cious activism of cyclists in places like New York City, despite tremen­dous “bike­lash,” may show Amer­i­cans they don’t need to look abroad to see how bikes could slow­ly dis­place cars as Amer­i­cans’ vehi­cles of choice in some parts of the coun­try. But learn­ing from how oth­er places have reimag­ined their infra­struc­ture could prove nec­es­sary for last­ing change.

Many Amer­i­cans can­not imag­ine life with­out their cars, even if they also have garages full of bikes. Some lash out at cyclists as a threat to their way of life. The coun­try is enor­mous (though we do most dri­ving local­ly); cars serve as modes of transport—for human, plant, ani­mal, and every­thing else—and also as escape pods and sta­tus sym­bols. Canning’s film shows us ordi­nary Amer­i­can men and women get­ting the gump­tion to trade some com­fort and secu­ri­ty for lives of minor adven­ture and eco­log­i­cal sim­plic­i­ty. (And a good many of them still have cars if they need them.)

We also see, in exhi­bi­tions like that pre­viewed in the video above how design prin­ci­ples and pol­i­cy can help make such choic­es eas­i­er and safer for every­one to make. Can­ning point­ed­ly frames her argu­ment in Moth­er­load around cycling’s rad­i­cal his­to­ry. “100 years before the bicy­cle saved me,” she says in the film’s offi­cial trail­er at the top, “it lib­er­at­ed the poor, empow­ered the suf­fragettes, and trans­formed soci­ety faster than any inven­tion in human his­to­ry. It could hap­pen again.”

Meditation for Beginners: Buddhist Monks & Teachers Explain the Basics

In the app-rich, nuance-starved cul­ture of late cap­i­tal­ism, we are encour­aged to con­flate two vast­ly dif­fer­ent con­cepts: the sim­ple and the easy. Maybe no bet­ter exam­ple exists than in the mar­ket­ing of meditation—the sell­ing of an activ­i­ty that, in essence, requires no spe­cial­ized equip­ment or infra­struc­ture. What medi­a­tion does require is a good instruc­tor and encour­age­ment. It is sim­ple. But it is not easy. It’s true, you’ll hear teach­ers rue­ful­ly admit, they don’t print this on the brochures for retreat cen­ters: but sus­tained med­i­ta­tion can be dif­fi­cult and painful just as well as it can induce seren­i­ty, peace, and joy. When we sit down to med­i­tate, we “feel our stuff,” to para­phrase David Byrne.

Next to the host of phys­i­cal com­plaints and exter­nal stres­sors clam­or­ing for atten­tion, if we’ve got per­son­al bad vibra­tions to con­tend with, they will ham­per our abil­i­ty to accept the present and relax. This is why, his­tor­i­cal­ly, those wish­ing to embark on the Bud­dhist path would first take eth­i­cal pre­cepts, and prac­tice them, before begin­ning to med­i­tate, under the pre­sump­tion that doing good (or non-harm) qui­ets the mind. “It is true that med­i­ta­tion is impor­tant in the Bud­dhist tra­di­tion,” writes Tibetan teacher Yongey Mingyur Rin­poche at Lion’s Roar. “But in many ways, ethics and virtue are the foun­da­tion of the Bud­dhist path.”

Of course, there are non-Bud­dhist med­i­ta­tion tra­di­tions. And the mind­ful­ness move­ment has demon­strat­ed with great suc­cess that one can carve most of the reli­gion away from med­i­ta­tion and still derive many short-term ben­e­fits from the prac­tice. But to do so is to dis­pense with thou­sands of years of expe­ri­en­tial wis­dom, not only about the dif­fi­cul­ties of sus­tain­ing a med­i­ta­tion prac­tice over the long term, but also about med­i­ta­tion’s inher­ent simplicity—something those of us inclined to over­com­pli­cate things may need to hear over and over again.

Tibetan teach­ers like Mingyur (and teach­ers from every Bud­dhist lin­eage) are gen­er­al­ly hap­py to expound upon the sim­plic­i­ty and joy of medi­a­tion, with the good nature we might expect of those who spend their lives let­ting go of regrets and fears. Some­times their mes­sages are pack­aged for eas­i­er con­sump­tion, which is a fine way to get a taste of some­thing before you decide to explore it fur­ther. But the point remains, as Mingyur says in the video at the top from The Jakar­ta Poet, that “med­i­ta­tion is com­plete­ly nat­ur­al.” It is not a prod­uct and does­n’t require any acces­sories or sub­scrip­tions.

It is also not an altered state of con­scious­ness or a nihilist escape. It is allow­ing our­selves to expe­ri­ence what is hap­pen­ing inside and all around us moment by moment by tun­ing into our aware­ness. We can do this any­where, at any time, for any length of time, as the monk fur­ther up tells us. “Even three sec­onds, two sec­onds, while you’re walk­ing, while you’re hav­ing cof­fee and tea, while you’re hav­ing a meet­ing… you can med­i­tate.” Real­ly? Yes, since med­i­ta­tion is not a vaca­tion from your life but an inten­si­fied expe­ri­enc­ing of it (even the meet­ings).

We get a celebri­ty endorse­ment above from the man who plays the angri­est man on tele­vi­sion, Gor­don Ram­say. The chef takes a break from his abu­sive kitchen rages to meet with a Thai monk, who says of his deci­sion to enter the monastery, “I’ve been to many dif­fer­ent places, I’d trav­eled around, but the one place I hadn’t looked at was my mind.” West­ern­ers may hear this and think of far out states—and there are plen­ty of those to be found in Bud­dhist texts, but not much talk of them among Bud­dhist teach­ers. Gen­er­al­ly, the word “mind” has a far more expan­sive range here than the fir­ing of synaps­es: it includes move­ment of the stom­ach lin­ing, the ten­sion of the sinews, and the beat­ing of the heart.

One of the most trag­ic mis­un­der­stand­ings of med­i­ta­tion casts it as a men­tal dis­ci­pline, split­ting mind and body as West­ern thought is wont to do for cen­turies now. But the aware­ness cul­ti­vat­ed in med­i­ta­tion is aware­ness of every­thing: the sens­es, the body, the breath, the space around us, our cog­ni­tion and emo­tion. Every Bud­dhist tra­di­tion and sec­u­lar off­shoot has its way of teach­ing stu­dents what to do with their often-ignored bod­ies while they med­i­tate. The dif­fer­ences between them are most­ly slight, and you’ll find a good guid­ed intro­duc­tion to begin­ning med­i­ta­tion focused on the body just above, led by Mingyur Rin­poche.

The hap­pi­ness one can derive from a med­i­ta­tion prac­tice does arrive, accord­ing to med­i­ta­tors world­wide, but it is not a soli­tary achieve­ment, Bud­dhist teach­ers say, a prize claimed for one­self like a prof­it wind­fall. It is, rather, the result of more com­pas­sion, and hence of more humil­i­ty, bet­ter rela­tion­ships, and less self-involve­ment; the result of strip­ping away rather than acquir­ing. Bud­dhist monk Matthieu Ricard, who left a career in cel­lu­lar genet­ics in his twen­ties to study and prac­tice in the Himalayas, hasn’t shied away from mar­ket­ing as a way to teach peo­ple to med­i­tate. But he is also upfront about the impor­tance of ethics to begin­ning medi­a­tion.

In addi­tion to being a “con­fi­dante of the Dalai Lama,” notes Busi­ness Insid­er, Ricard is also “a viral TED Talk speak­er, and a best­selling author.” His mes­sage is the impor­tance of compassion—not as a goal to achieve some time in the future, but as the very place to start. “There’s noth­ing mys­te­ri­ous” about it, he says in an inter­view on Busi­ness Insider’s pod­cast. He then goes on to describe the basic prac­tices of “Met­ta, ”among oth­er things a way of train­ing one­self to have kind and lov­ing inten­tions for oth­ers in an ever-widen­ing cir­cle out­ward. In the video above, Ricard talks about the prac­tice, and the sci­ence, of com­pas­sion at Google.

Many peo­ple balk at this kind of sen­ti­men­tal stuff, even from a man Google describes as “the world’s best bridge between mod­ern sci­ence and ancient wis­dom.” But if we can hear any­thing in the ancient wis­dom dis­tilled by these Bud­dhist teach­ers, per­haps it’s a sim­ple idea fast-med­i­ta­tion apps and util­i­tar­i­an pro­grams gen­er­al­ly skip. No, you do not need to put on robes, become a monk or nun, or take on a set of ancient tra­di­tions, beliefs, or rit­u­als. But as Amer­i­can Bud­dhist teacher Jack Korn­field says below, “if you want to learn to be wise and present, the first step is to refrain from harm­ing your­self or oth­ers.”

What Happens To Your Body & Brain If You Don’t Get Sleep? Neuroscientist Matthew Walker Explains

As an insom­ni­ac in a morn­ing person’s world, I wince at sleep news, espe­cial­ly from Matthew Walk­er, neu­ro­sci­en­tist, Berke­ley pro­fes­sor, and author of Why We Sleep. Some­thing of a “sleep evan­ge­list,” as Berke­ley News calls him (he prefers “sleep diplo­mat”), Walk­er has tak­en his mes­sage on the road—or the 21st cen­tu­ry equiv­a­lent: the TED Talk stages and ani­mat­ed explain­er videos.

One such video has Walk­er say­ing that “sleep when you’re dead” is “mor­tal­ly unwise advice… short sleep pre­dicts a short­er life.” Or as he elab­o­rates in an inter­view with Fresh Air’s Ter­ry Gross, “every dis­ease that is killing us in devel­oped nations has causal and sig­nif­i­cant links to a lack of sleep.”

Yeesh. Does he lay it on thick? Nope, he’s got the evi­dence and wants to scare us straight. It’s a psy­cho­log­i­cal tac­tic that hasn’t always worked so well, although next to “sleep or die” ser­mons, there’s good news: sleep, when har­nessed prop­er­ly (yes, some­where in the area of 8 hours a night) can also be a “super­pow­er.” Sleep does “won­der­ful­ly good things… for your brain and for your body,” boost­ing mem­o­ry, con­cen­tra­tion, and immu­ni­ty, just for starters.

But back to the bad.…

In the Tech Insid­er video above, Walk­er deliv­ers the grim facts. As he fre­quent­ly points out, most of us need to hear it. Sleep depri­va­tion is a seri­ous epidemic—brought on by a com­plex of socio-eco­nom­ic-politi­co-tech­no­log­i­cal fac­tors you can prob­a­bly imag­ine. See Walker’s com­par­isons (to the brain as an email inbox and a sewage sys­tem) ani­mat­ed, and learn about how lack of sleep con­tributes to a 24% increase in heart attacks and numer­ous forms of can­cer. (The World Health Orga­ni­za­tion has recent­ly “clas­si­fied night­time shift work as a prob­a­ble car­cino­gen.”)

On the upside, rarely is health sci­ence so unam­bigu­ous. If nutri­tion­ists could only give us such clear-cut advice. Whether we’d take it is anoth­er ques­tion. Learn more about the mul­ti­ple, and some­times fatal, con­se­quences of sleep depri­va­tion in the ani­mat­ed TED-Ed video above.

The Therapeutic Benefits of Ambient Music: Science Shows How It Eases Chronic Anxiety, Physical Pain, and ICU-Related Trauma

“In forty years of med­ical prac­tice,” wrote Dr. Oliv­er Sacks near the end of his famous career, “I have found only two types of non-phar­ma­ceu­ti­cal ‘ther­a­py’ to be vital­ly impor­tant for patients with chron­ic neu­ro­log­i­cal dis­eases: music and gar­dens.” The com­ment might not sur­prise us, com­ing from such an unortho­dox thinker as Sacks. But we might be sur­prised by the con­sid­er­able amount of tra­di­tion­al sci­en­tif­ic research link­ing music and men­tal health.

Six­ty years ago, when Sacks was still in med­ical school, avant-garde jazz band­leader Sun Ra had a very Sacks-like expe­ri­ence when he played for an audi­ence of patients in a men­tal hos­pi­tal, and inspired a cata­ton­ic woman who hadn’t spo­ken for years to stand up and say ‘Do you call that music?’” The gig, booked by his man­ag­er, con­sti­tut­ed a fringe exper­i­ment in alter­na­tive med­i­cine at the time, not a seri­ous sub­ject of study among med­ical doc­tors and neu­ro­sci­en­tists.

How things have changed in the last half-cen­tu­ry.

Sev­er­al recent stud­ies, for exam­ple, have linked drum­ming, the old­est and most uni­ver­sal form of music-mak­ing, to reduced anx­i­ety, pain relief, improved mood, and improved learn­ing skills in kids with autism. Lis­ten­ing to and play­ing jazz and oth­er forms of syn­co­pat­ed music, have been shown in study after study to pro­mote cre­ativ­i­ty, enhance math skills, and sup­port men­tal and emo­tion­al well-being.

But what about ambi­ent music, a genre often char­ac­ter­ized by its lack of syn­co­pa­tion, and almost cer­tain to fea­ture as back­ground music in guid­ed med­i­ta­tion and stress reduc­tion record­ings; in slow, relax­ing yoga videos; and thou­sands of YouTube videos pro­mot­ing sup­pos­ed­ly stress-reduc­ing fre­quen­cies and stereo effects? Ambi­ent seems pur­pose-built to com­bat ten­sion and dis-ease, and in a sense, it was.

Bri­an Eno, the artist who named the genre and often gets cred­it for its inven­tion, wrote in the lin­er notes to Ambi­ent 1: Music for Air­ports, “[this record is] designed to induce calm and space to think.” Whether he meant to make a sci­en­tif­ic claim or only an artis­tic state­ment of pur­pose, research has val­i­dat­ed his infer­ences about the salu­tary effects of long, slow, atmos­pher­ic music.

Noisey Asso­ciate Edi­tor Ryan Bassil, a long­time suf­fer­er of anx­i­ety and pan­ic attacks, found the state­ment to be true in his own life, as he explains in the video above (illus­trat­ed by Nathan Cowdry). Music from ambi­ent com­posers like Eno, William Bassin­s­ki, and Fen­nesz helped him “ground” him­self dur­ing extreme­ly anx­ious moments, bring­ing him back into sen­so­ry con­tact with the present.

When Bassil looked into the rea­sons why ambi­ent music had such a calm­ing effect on his over-stim­u­lat­ed ner­vous sys­tem, he found research from artist and aca­d­e­m­ic Luke Jaaniste, who described an “ambi­ent mode,” a “per­va­sive all-around field, with­out any­thing being pri­or­i­tized into fore­ground and back­ground.” Immer­sion in this space, writes Bassil, “can help the lis­ten­er put aside what’s on their mind and use their sens­es to focus on their sur­round­ings.”

We may not—and should not—ask music to be a use­ful tool, but ambi­ent has shown itself par­tic­u­lar­ly so when treat­ing seri­ous neu­ro­log­i­cal and psy­cho­log­i­cal con­di­tions. Foren­sic psy­chi­a­trist Dr. John Tul­ly of London’s Insti­tute of Psy­chi­a­try, Psy­chol­o­gy and Neu­ro­science traces the form back to Bach and Chopin, and espe­cial­ly Erik Satie, who “was the first to express the idea of music specif­i­cal­ly as back­ground sound,” and who had no qualms about music serv­ing a spe­cial­ized pur­pose.

The pur­pose of what we broad­ly call ambi­ent has evolved and changed as clas­si­cal, min­i­mal­ist avant-garde, and elec­tron­ic musi­cians have penned com­po­si­tions for very dif­fer­ent audi­ences. But no mat­ter the intent, or where we draw the genre bound­aries, all kinds of atmos­pher­ic, instru­men­tal music has the ther­a­peu­tic pow­er not only to reduce anx­i­ety, but also to ease pain in sur­gi­cal patients and reduce agi­ta­tion in those suf­fer­ing with demen­tia.

When he per­formed with his group Dark­room at the Crit­i­cal Care Unit at Uni­ver­si­ty Col­lege Lon­don Hos­pi­tal, writer and psy­chol­o­gist Charles Fer­ny­hough found out that ambi­ent music had sig­nif­i­cant ben­e­fits for patients trapped in what he calls “a sub­urb of hell”: the ICU. Stays in inten­sive care units cor­re­late close­ly with lat­er PTSD and what was once called “ICU psy­chosis” in the midst of trau­mat­ic emer­gency room expe­ri­ences. Seda­tion turns out to be a major cul­prit. But music, espe­cial­ly ambi­ent music, brought patients back to them­selves.

Hear the 2016 Dark­room per­for­mance at the Uni­ver­si­ty Col­lege Lon­don Hos­pi­tal ICU fur­ther up, and read more about Fernyhough’s research and per­for­mance at Aeon. The sci­ence of how and why ambi­ent works the way it does is hard­ly set­tled. Where Fer­ny­hough found that patients ben­e­fit­ed from a lack of pre­dictabil­i­ty and an abil­i­ty to “escape the present moment,” Bassil’s research and expe­ri­ence uncov­ered the opposite—a sense of safe pre­dictabil­i­ty and enhanced sen­so­ry aware­ness.

Phys­i­o­log­i­cal respons­es from per­son to per­son will vary, as will their tastes. “One person’s easy lis­ten­ing is another’s aur­al poi­son,” Fer­ny­hough admits. But for a sig­nif­i­cant num­ber of peo­ple suf­fer­ing severe anx­i­ety and trau­ma, the dron­ing, min­i­mal, word­less sound­scapes of ambi­ent are more effec­tive than any med­ica­tion.

The 1855 Map That Revolutionized Disease Prevention & Data Visualization: Discover John Snow’s Broad Street Pump Map

No, he didn’t help defeat an implaca­ble zom­bie army intent on wip­ing out all life. But Eng­lish obste­tri­cian John Snow seems as impor­tant as the sim­i­lar­ly-named Game of Thrones hero for his role in per­suad­ing mod­ern med­i­cine of the germ the­o­ry of dis­ease. Dur­ing the 1854 out­break of cholera in Lon­don, Snow con­vinced author­i­ties and crit­ics that the dis­ease spread from a con­t­a­m­i­nat­ed water pump on Broad Street, lead­ing to the now-leg­endary info­graph­ic map above show­ing the inci­dences of cholera clus­tered around the pump.

Snow’s per­sis­tence result­ed in the removal of the han­dle from the Broad Street pump and has been cred­it­ed with end­ing an epi­dem­ic that claimed 500 lives. The Broad Street pump map has become “an endur­ing fea­ture of the folk­lore of pub­lic health and epi­demi­ol­o­gy,” write the authors of an arti­cle pub­lished in The Lancet. They also point out that, con­trary to pop­u­lar retellings, the “map did not give rise to the insight” that the pump and its germ-cov­ered han­dle caused the out­break. “Rather it tend­ed to con­firm the­o­ries already held by the var­i­ous inves­ti­ga­tors.”

Snow him­self pub­lished a pam­phlet in 1849 called “On the Mode of Com­mu­ni­ca­tion of Cholera” in which he argued that “cholera is com­mu­ni­cat­ed by the evac­u­a­tions from the ali­men­ta­ry canal.” As he remind­ed read­ers of The Edin­burgh Med­ical Jour­nal in an 1856 let­ter, in that same year, “Dr William Budd pub­lished a pam­phlet ‘On Malig­nant Cholera’ in which he expressed views sim­i­lar to my own.” Germ the­o­ry had a long, dis­tin­guished his­to­ry already, and Snow and his con­tem­po­raries made sound, evi­dence-based argu­ments for it.

But their posi­tion “large­ly went ignored by the med­ical estab­lish­ment,” notes Randy Alfred at Wired, “and was opposed by a local water com­pa­ny near one Lon­don out­break.” The accept­ed, main­stream sci­en­tif­ic opin­ion held that all dis­ease was spread through “mias­ma,” or bad air. Pol­lu­tion, it was thought, must be the cause. After the pump handle’s removal, Snow pub­lished an 1855 mono­graph on water­borne dis­eases. This was the first pub­lic appear­ance of the leg­endary map—after the removal of the han­dle.

Help­ing to inform Snow’s map, anoth­er inves­ti­ga­tor, parish priest Hen­ry White­head had “con­clud­ed that it was the wash­ing of soiled dia­pers into drains which flowed to the com­mu­nal cesspool that con­t­a­m­i­nat­ed the pump and start­ed the out­break,” writes Atlas Obscu­ra. White­head, a for­mer crit­ic of germ the­o­ry, lat­er point­ed out that the removal of the pump han­dle didn’t actu­al­ly stop the epi­dem­ic, which, he said, “had already run its course” by that point.

Nonethe­less, Snow and oth­er pro­po­nents of the the­o­ry were vin­di­cat­ed, White­head had to admit, and Snow’s inter­ven­tion “had prob­a­bly every­thing to do with pre­vent­ing a new out­break.” The sim­ple, yet sophis­ti­cat­ed data visu­al­iza­tion would lead to rad­i­cal new ways of con­cep­tu­al­iz­ing dis­ease out­breaks, help­ing to stop or pre­vent who knows how many epi­demics before they killed hun­dreds or thou­sands. Snow’s map also deserves cred­it for giv­ing “data jour­nal­ists a mod­el of how to work today.”

It was hard­ly the first or only data visu­al­iza­tion of cholera out­breaks of the time. “As ear­ly as the 1830s,” Visu­al Cap­i­tal­ist points out, “geo­g­ra­phers began using spa­cial analy­sis to study cholera epi­demi­ol­o­gy.” But Snow’s was by far the most influ­en­tial, and effec­tive, of them all. In his TED talk above, jour­nal­ist Steven John­son (author of The Ghost Map:The Sto­ry of Lon­don’s Most Ter­ri­fy­ing Epi­dem­ic and How It Changed Sci­ence, Cities, and the Mod­ern World) tells the sto­ry of how the out­break, and Snow’s the­o­ry and map, “helped cre­ate the world that we live in today, and par­tic­u­lar­ly the kind of city that we live in today.”

How Sleep Can Become Your “Superpower:” Scientist Matt Walker Explains Why Sleep Helps You Learn More and Live Longer

“I’ll sleep when I’m dead”: those words have been a mantra to hard-liv­ing types every­where since War­ren Zevon first sang them back in 1976, but as Berke­ley sleep sci­en­tist and Why We Sleep author Matt Walk­er sees it, tak­ing them to heart is a “mor­tal­ly unwise” choice. The exam­ple of Zevon him­self, who died at the age of 53, would seem to val­i­date that judge­ment, but it also comes backed by seri­ous research. In the TED Talk “Sleep Is Your Super­pow­er” above, Walk­er builds on what we all know — that we need to sleep, reg­u­lar­ly and with­out inter­rup­tion — by explain­ing “the won­der­ful­ly good things that hap­pen when you get sleep, but the alarm­ing­ly bad things that hap­pen when you don’t get enough, both for your brain and for your body.”

Not only, for exam­ple, do “you need sleep after learn­ing to essen­tial­ly hit the save but­ton on those new mem­o­ries so that you don’t for­get,” you also “need sleep before learn­ing to actu­al­ly pre­pare your brain, almost like a dry sponge ready to ini­tial­ly soak up new infor­ma­tion.”

As any­one who has tried to pull an all-nighter before a big test has felt, sleep depri­va­tion shuts down your “your mem­o­ry inbox,” and any incom­ing files just get “bounced” with­out being retained. But deep-sleep brain­waves, as Walk­er puts it, act as a “file-trans­fer mech­a­nism at night, shift­ing mem­o­ries from a short-term vul­ner­a­ble reser­voir to a more per­ma­nent long-term stor­age site with­in the brain, and there­fore pro­tect­ing them, mak­ing them safe.”

Improp­er sleep threat­ens not just learn­ing but life itself: com­pro­mised sleep means a com­pro­mised immune sys­tem, hence the “sig­nif­i­cant links between short sleep dura­tion and your risk for the devel­op­ment of numer­ous forms of can­cer” now being dis­cov­ered. “The short­er your sleep, the short­er your life,” as Walk­er stark­ly puts it. As far as how to improve your sleep and, with luck, elon­gate your life, he has two main pieces of advice: “Go to bed at the same time, wake up at the same time, no mat­ter whether it’s the week­day or the week­end,” and “aim for a bed­room tem­per­a­ture of around 65 degrees, or about 18 degrees Cel­sius,” slight­ly cool­er than may feel nor­mal. We’d also do well to remem­ber the impor­tance of break­ing the habit of stay­ing on the inter­net late into the night — or more specif­i­cal­ly, hav­ing stayed up well past mid­night writ­ing this very post, I’d do well to remem­ber it.

Oliver Sacks Promotes the Healing Power of Gardens: They’re “More Powerful Than Any Medication”

Ear­ly Euro­pean explor­ers left the con­ti­nent with visions of gar­dens in their heads: The Gar­den of Eden, the Gar­den of the Hes­perides, and oth­er myth­ic realms of abun­dance, ease, and end­less repose. Those same explor­ers left sick­ness, war, and death only to find sick­ness, war, and death—much of it export­ed by them­selves. The gar­den became de-mythol­o­gized. Nat­ur­al phi­los­o­phy and mod­ern meth­ods of agri­cul­ture brought gar­dens fur­ther down to earth in the cul­tur­al imag­i­na­tion.

Yet the gar­den remained a spe­cial fig­ure in phi­los­o­phy, art, and lit­er­a­ture, a potent sym­bol of an ordered life and ordered mind. Voltaire’s Can­dide, the riotous satire filled with gar­dens both fan­tas­ti­cal and prac­ti­cal, famous­ly ends with the dic­tate, “we must cul­ti­vate our gar­den.” The ten­den­cy to read this line as strict­ly metaphor­i­cal does a dis­ser­vice to the intel­lec­tu­al cul­ture cre­at­ed by Voltaire and oth­er writ­ers of the peri­od—Alexan­der Pope most promi­nent among them—for whom gar­den­ing was a the­o­ry born of prac­tice.

Exiled from France in 1765, Voltaire retreat­ed to a vil­la in Gene­va called Les Délices, “The Delights.” There, writes Adam Gop­nik at The New York­er, he “quick­ly turned his exile into a desir­able con­di­tion…. When he wrote that it was our duty to cul­ti­vate our gar­den, he real­ly knew what it meant to cul­ti­vate a gar­den.” Enlight­en­ment poets and philoso­phers did not dwell on the sci­en­tif­ic rea­sons why gar­dens might have such salu­tary effects on the psy­che. And nei­ther does neu­rol­o­gist Oliv­er Sacks, who also wrote of gar­dens as health-bestow­ing havens from the chaos and noise of the world, and more specif­i­cal­ly, from the city and bru­tal com­mer­cial demands it rep­re­sents.

For Sacks that city was not Paris or Lon­don but, prin­ci­pal­ly, New York, where he lived, prac­ticed, and wrote for fifty years. Nonethe­less, in his essay “The Heal­ing Pow­er of Gar­dens,” he invokes the Euro­pean his­to­ry of gar­dens, from the medieval hor­tus to grand Enlight­en­ment botan­i­cal gar­dens like Kew, filled with exot­ic plants from “the Amer­i­c­as and the Ori­ent.” Sacks writes of his stu­dent days, where he “dis­cov­ered with delight a very dif­fer­ent garden—the Oxford Botan­ic Gar­den, one of the first walled gar­dens estab­lished in Europe,” found­ed in 1621.

“It pleased me to think,” he recalls, refer­ring to key Enlight­en­ment sci­en­tists, “that Boyle, Hooke, Willis and oth­er Oxford fig­ures might have walked and med­i­tat­ed there in the 17th cen­tu­ry.” In that time, cul­ti­vat­ed gar­dens were often the pri­vate pre­serves of land­ed gen­try. Now, places like the New York Botan­i­cal Gar­den, whose virtues Sacks extolls in the video above, are open to every­one. And it is a good thing, too. Because gar­dens can serve an essen­tial pub­lic health func­tion, whether we’re stressed and gen­er­al­ly fatigued or suf­fer­ing from a men­tal dis­or­der or neu­ro­log­i­cal con­di­tion:

I can­not say exact­ly how nature exerts its calm­ing and orga­niz­ing effects on our brains, but I have seen in my patients the restora­tive and heal­ing pow­ers of nature and gar­dens, even for those who are deeply dis­abled neu­ro­log­i­cal­ly. In many cas­es, gar­dens and nature are more pow­er­ful than any med­ica­tion.

“In forty years of med­ical prac­tice,” the physi­cian writes, “I have found only two types of non-phar­ma­ceu­ti­cal ‘ther­a­py’ to be vital­ly impor­tant for patients with chron­ic neu­ro­log­i­cal dis­eases: music and gar­dens.” A gar­den also represents—for Sacks and for artists like Vir­ginia Woolf—“a tri­umph of resis­tance against the mer­ci­less race of mod­ern life,” as Maria Popo­va writes at Brain Pick­ings, a pace “so com­pul­sive­ly focused on pro­duc­tiv­i­ty at the cost of cre­ativ­i­ty, of lucid­i­ty, of san­i­ty.”

Voltaire’s pre­scrip­tion to tend our gar­dens has made Can­dide into a watch­word for car­ing for and appre­ci­at­ing our sur­round­ings. (It’s also now the name of a gar­den­ing app). Sacks’ rec­om­men­da­tions should inspire us equal­ly, whether we’re in search of cre­ative inspi­ra­tion or men­tal respite. “As a writer,” he says, “I find gar­dens essen­tial to the cre­ative process; as a physi­cian, I take my patients to gar­dens when­ev­er pos­si­ble. The effect, he writes, is to be “refreshed in body and spir­it,” absorbed in the “deep time” of nature, as he writes else­where, and find­ing in it “a pro­found sense of being at home, a sort of com­pan­ion­ship with the earth,” and a rem­e­dy for the alien­ation of both men­tal ill­ness and the grind­ing pace of our usu­al form of life.

Exercise May Prove an Effective Natural Treatment for Depression & Anxiety, New Study Shows

Image by cue­ga­los, via Flickr Com­mons

Maybe it seems intu­itive that exer­cise would be pre­scribed to treat anx­i­ety and depres­sion, low­er stress lev­els, and make peo­ple hap­pi­er. After all, exer­cise and nutri­tion­al inter­ven­tions are reg­u­lar­ly dis­cussed in the con­text of the U.S.’s oth­er major killers: heart dis­ease, dia­betes, var­i­ous can­cers, even Alzheimer’s. How often have we heard about the dan­gers of a seden­tary lifestyle or over-processed foods? Or read about reme­dies from walk­ing, yoga, and spin cycling to the Mediter­ranean diet?

But men­tal health is seem­ing­ly different—the dis­ease mod­el that guid­ed depres­sion research for so long has fal­tered. “We do not have a biol­o­gy for men­tal ill­ness,” writes Derek Beres at Big Think. Researchers lack a med­ical pathol­o­gy for mood dis­or­ders that affect over­all health, careers, rela­tion­ships, and qual­i­ty of life for mil­lions. The anti­de­pres­sants once sold as a cure-all and pre­scribed to dizzy­ing degrees proved to have lim­it­ed effi­ca­cy and unfor­tu­nate side effects. No one seems to know exact­ly how or why or if they work. “Men­tal health scripts are guess­work,” Beres writes, “more of an art than sci­ence.”

Where does this leave the state of men­tal health research these days? One team of sci­en­tists at the Uni­ver­si­ty of Ver­mont found evi­dence that exer­cise sig­nif­i­cant­ly improved mood in patients with severe and chron­ic men­tal ill­ness­es. As Newsweek reports, “a total of 100 patients signed up to par­tic­i­pate in the study,” whose results were pub­lished recent­ly in the jour­nal Glob­al Advances in Health and Med­i­cine. The study vol­un­teers came from “wards that dealt with con­di­tions such as bipo­lar dis­or­der, depres­sion, bor­der­line per­son­al­i­ty dis­or­der, gen­er­al­ized anx­i­ety dis­or­der and schiz­o­phre­nia.”

After a work­out sched­ule that includ­ed car­dio, resis­tance, and flex­i­bil­i­ty train­ing, four times a week for six­ty min­utes at a time, as well as nutri­tion­al pro­grams “tai­lored” for each patient, 95 per­cent of the par­tic­i­pants “said their mood has improved… and 63 per­cent said they were ‘hap­py’ or ‘very hap­py,’ rather than ‘neu­tral,’ ‘sad,’ or ‘very sad.’” 97.6 said they were moti­vat­ed to con­tin­ue work­ing out and eat­ing bet­ter. “The research yield­ed pos­i­tive out­comes in all areas inves­ti­gat­ed,” write authors David Tomasi, Sheri Gates, and Emi­ly Reyns of the study’s results. They con­clude that phys­i­cal exer­cise may con­tribute to “a more bal­anced and inte­grat­ed sense of self.”

The researchers also rec­om­mend exer­cise as a treat­ment before the pre­scrip­tion of psy­chi­atric drugs. There may not yet be a clear med­ical expla­na­tion for why it works. But that may be because mod­ern med­i­cine has only recent­ly begun to see the mind and the body as one, at a time when our cul­tur­al evo­lu­tion sends us hurtling toward a greater arti­fi­cial divide between the two. “We’ve con­struct­ed a world in which most of the pop­u­la­tion sur­vives by per­form­ing min­i­mal phys­i­cal activ­i­ty.” A world soon to be engulfed in VR, AR, self-dri­ving cars, and an “inter­net of things” that promis­es to elim­i­nate the few phys­i­cal tasks we have left.

We are in dan­ger of for­get­ting that our men­tal and emo­tion­al health are direct­ly tied to the needs of our phys­i­cal bod­ies, and that our bod­ies need to move, stretch, and bend in order to stay alive and thrive.
