Big tech and startup tech tackle sleep

Longform GQ article on “The Business of Sleep” has some perspective:

If you want to isolate a time when the idea of wellness began to dominate our culture, you could do worse than point to the 2008 financial crisis. In a few short months an entire generation felt their grip on the future slip. Jobs became scarce, before scarcely becoming jobs. Zero hours became the new nine to five. Suddenly, nearly everyone needed a side hustle and nearly everyone else needed to be told what one was. Property became a pipe dream. Social media showed them what they didn’t have. Generation Anxious was born.

and

One upshot of the 2008 financial crisis, he says, was that, in the following years, “It wasn’t cool to sleep four hours a night any more, you know? There used to be this whole banker culture, crushing it at work, 100-hour weeks, let’s brag about how little sleep we get. And we started to turn the curve on that. When we started in 2014, our goal was to think about people sleeping better. People resting more. We got people to start thinking about sleep.”

But then you have addictive design from social media and streaming video services, with quotes from Netflix’s CEO like

“When you watch a show from Netflix and you get addicted to it, you stay up late at night. We’re competing with sleep.”

contrasted with Apple, which built the elegantly designed Bedtime night-and-morning alert feature into iOS, a feature I have used every day since it was released. This makes it

And so, when you are sitting there wondering if you should keep watching or scrolling or simply go to bed, chances are you’re making a choice between the largest companies on earth: Netflix (£127bn value), Amazon (£789bn), YouTube (owned by Google: £583bn), Facebook (£375bn) and Twitter (£21bn) on the one hand and Apple (£789bn) on the other.

“Can caffeine improve your exercise performance?”

Yes. Though not that much.

How?

“During waking hours, adenosine slows down brain activity and results in feelings of fatigue. When we have caffeine, the caffeine binds to the adenosine receptors and has the opposite effect of adenosine. It reduces fatigue and our perception of effort (for example, how hard it feels to perform an exercise).”

How much?

“Experts believe caffeine doses between 3 and 6 mg/kg are needed to improve performance. That’s 210 to 420mg for a 70kg person, or about two cups of coffee.”

“Those who respond most strongly to caffeine might see improvements of around 16%, but this is unusual. For the average person, improvements will likely be between about 2% and 6%.”

When?

“Experts believe caffeine doses between 3 and 6 mg/kg are needed to improve performance. That’s 210 to 420mg for a 70kg person, or about two cups of coffee.”
