Demonizing sitting and oversimplifying its health effects can do more harm than good.

Why Sitting Down All Day Is not As Unhealthy For Your Well being As You Worry

The concept that “sitting is the brand new smoking” has been round for a number of years now. It’s credited to James Levine, an endocrinologist and weight problems researcher on the Mayo Clinic, who claims in his 2014 e book “Get Up! that we lose two hours of life for each hour we spend sitting.

Within the constructing that homes my graduate faculty courses, there’s a room with two treadmill desks that employees and college students are inspired to make use of. In most workplace buildings, you’ll see standing desks, which are sometimes marketed because the “finish to unhealthy work environments” or as a method to fight again ache and weight acquire.

However, credentialed as Levine could also be, the declare that sitting is as dangerous as smoking has all the time appeared far-fetched and a bit clickbait-y to me. Like many others, I’ve a desk job. I’m pretty lively in my leisure time, however there’s actually no method round the truth that I should be idle for an excellent chunk of daily. In order that’s one cause equating desk chairs to cigarettes doesn’t fairly observe — nobody wants to smoke, however virtually everybody wants to sit down.

Exercised,” a brand new e book by paleoanthropologist and Harvard evolutionary biology professor Dan Lieberman, flips the script on concepts like sitting is the brand new smoking. “The fundamental argument of my e book is that we make individuals really feel exercised about train and bodily exercise,” Lieberman stated. “We make them really feel anxious and nervous and nervous and confused as a result of we give all of them this unhealthy data, and there’s a number of worth and judgment added to it.”

Oversimplifications (and straight-up myths) about motion can do extra hurt than good, Lieberman argues. That is very true with regards to that fearmongering one-liner on the harms of sitting.

Sitting isn’t a contemporary invention.

Central to this sense of fear we now have about sitting is the belief that folks residing in much less industrialized societies, previous and current, sit significantly lower than we do. Lieberman takes challenge with this for a number of causes.

“We get this concept that, ‘If hunter-gatherers do it, it should be good for us.’ That’s trash pondering. Sadly, it’s quite common,” Lieberman stated, citing the paleo food regimen for instance. “It’s a extremely, actually unhealthy method to consider making use of evolution to well being.”

Why? As a result of our ancestors didn’t evolve to be wholesome, they developed to breed and have as many offspring as potential. So, let’s cease making an attempt to imitate their life-style habits within the identify of well being.

That stated, it’s additionally not true that sitting is exclusive to industrialized society. “Should you go and take a look at what [today’s] hunter-gatherers do, it seems that they sit about 10 hours a day, too,” Lieberman stated. “Your common hunter-gatherer on the market who has no chairs and doesn’t have a desk job, they sit as a lot as most People.”

Many sit or squat on the ground, which engages a number of extra muscular tissues than sitting in a chair, however remains to be a relaxed and restful place.

Demonizing sitting and oversimplifying its well being results can do extra hurt than good.

There are every kind of conflicting statistics on the market about how a lot we sit.

Details about the so-called risks of sitting is commonly accompanied by some surprising statistic about how a lot time we People spend sitting daily.

“Should you get on-line and go-ogle ‘How a lot do People sit?,’ the primary 5 or 6 responses provides you with 5 or 6 utterly, completely totally different solutions,” Lieberman stated. (I simply Googled it and located a 2019 Washington Publish article claiming that American adults sit six and a half hours per day, adopted by a 2019 Forbes article that claims 15 hours per day.) “Individuals simply make stuff up, or they choose the information that matches their argument.”

Based on Lieberman, high-quality knowledge that depends on accelerometers (electrical sensors that measure acceleration and may inform once we’re sitting, standing and laying down) finds a ton of variation in what number of hours individuals spend sitting. Some individuals are doing it way over others, and even the sitting habits of people differ tremendously from daily ― significantly weekdays versus weekends.

Due to this, “there’s nobody helpful quantity” that applies to all of us, Lieberman stated. Nonetheless, there are averages: Youthful American adults sit about 9 or 10 hours a day, whereas older adults sit as a lot as 12 to 13 hours a day.

Leisure time sitting is extra strongly related to poor well being than sitting throughout work.

The concept that sitting is perhaps the brand new smoking might be most alarming to these of us that haven’t any selection however to sit down for lengthy intervals at work. However, Lieberman’s e book highlights some reassuring proof. A 15-year cohort research of over 10,000 adults in Denmark discovered that sedentary work was not related to an elevated threat of coronary heart illness; a cohort research of 66,000 adults in Japan had related findings.

“It’s not a lot that chairs are evil and sitting is basically unhealthy for you,” Lieberman stated. “It’s that sitting an excessive amount of is unhealthy for you in case you don’t additionally train.”

Should you drive to work within the morning (sitting), sit at your desk all day, drive residence (sitting), after which spend the rest of your night on the sofa, which means you aren’t getting in a lot motion. “However it’s completely potential to be a bodily lively particular person and nonetheless sit for 9 or 10 hours a day,” Lieberman stated.

Getting out of your chair for just a minute or two can be beneficial. 

Getting out of your chair for only a minute or two may be useful. 

Getting up incessantly is basically useful, no matter how a lot time you spend sitting.

There’s a cause why some individuals recommend after-dinner walks as a method to assist with digestion. When your muscular tissues are activated, even by way of mild exercise like strolling or cooking, they soak up sugar and fats molecules out of your bloodstream to make use of as power.

While you sit uninterrupted for lengthy intervals of time, these sugar and fats molecules keep in your bloodstream for longer, which is one cause some individuals argue that an excessive amount of sitting raises your threat of sort 2 diabetes.


Nonetheless, you may mitigate this threat by merely getting up extra usually. Lieberman defined that in research the place researchers regarded on the the period of sitting bouts — that’s, how lengthy you sit with out getting up — individuals who rise up each 12 minutes have a a lot decrease power illness threat than individuals who sit for upwards of half-hour at a time, even after they sit for a similar quantity of complete time every day.

“The explanation for that’s that you just’re mainly turning in your muscular tissues extra usually,” Lieberman stated. “While you flip in your muscular tissues, even when just a bit bit, you cut back the quantity of fats and sugar in your bloodstream, and your muscular tissues are induced to provide anti-inflammatory molecules.”

He advised getting up each now and again to get water or a cup of tea, pet your canine, discuss to a coworker, run an errand — no matter will get you out of your chair for a minute or two.

“It’s not a lot that chairs are evil and sitting is basically unhealthy for you. It’s that sitting an excessive amount of is unhealthy for you in case you don’t additionally train.”

A standing desk isn’t a magic bul-let.

Lieberman has a standing desk and stated he makes use of it a good quantity. (Though not on a regular basis — he used an accelerometer to measure his personal patterns and located that he sits for a mean of eight and a half hours per day.)

However, most individuals misunderstand the potential advantages of standing desks. First, there haven’t been any high-quality research linking standing desks to diminished dangers of power illnesses. Second, whereas some individuals use standing desks in an try to forestall or reduce decrease again ache, the proof finds no vital affiliation between sitting (slouched or straight) and again ache within the first place. Third, whereas they’re typically marketed as weight reduction instruments, standing burns simply eight extra energy per hour than sitting. (Plus, even actions that bu-rn a big variety of energy aren’t strongly related to weight reduction.)

“Let’s not faux they’re train,” Lieberman stated.

He equates standing to a extra lively type of sitting, like squatting or sitting in a chair with out a again, as a result of you must interact some muscular tissues to remain upright. So, a standing desk may need the identical constructive impact as getting out of your chair every now and then.

If you're active outside of your working hours, you're benefiting your health to where sitting doesn't matter as much.

Should you’re lively outdoors of your working hours, you are benefiting your well being to the place sitting would not matter as a lot.

Don’t purchase into oversimplified and hyperbolic well being recommendation.

Sitting isn’t the brand new smoking. It’s potential to have a sedentary job and nonetheless get the really useful quantity of bodily exercise and maintain your threat of power illness comparatively low (granted you’re partaking in different wholesome behaviors like consuming a nutritious food regimen, not smoking, managing stress and consuming reasonably if in any respect.)

Nonetheless, Lieberman’s argument isn’t that we must always simply forged apart the concept that an excessive amount of sitting is perhaps dangerous.

“It’s true that bodily exercise is sweet for you and an excessive amount of sitting is unhealthy for you,” he stated. “However as a substitute of explaining why that could be, many well being consultants simply demonize and oversimplify.”

Demonizing one thing as pure and needed as sitting is unhelpful as a result of it doesn’t present an actionable answer. Plus, it stresses individuals out, which is decidedly unhealthy for well being.

As an alternative, Lieberman thinks that “individuals deserve extra and higher data. They will deal with a bit little bit of complexity.” As an alternative of making an attempt to distill the proof on sitting down to at least one (scary!) sentence, a greater method can be to clarify how and why an excessive amount of sitting may be dangerous, after which providing some lifelike options: Stand up out of your desk a number of occasions an hour, attempt a standing desk if you need, find time for bodily exercise earlier than or after work.

Understanding this, individuals can modify their habits for the higher, as a substitute of feeling overwhelmed by messages that make small adjustments appear futile.
