Why We Sleep, and Why We Often Can’t
Does our contemporary obsession with sleep obscure what makes it special in the first place?

Sleep as a Competitive Advantage
Too many of us live by the myth that one less hour of sleep gives us one more hour of productivity, Tony Schwartz writes in the Life@Work column. In reality, lost sleep not only leaves us more fatigued, but also takes a toll on our cognitive capacity.

What Did Ancient Humans Do at Night?
Sleep deprivation is not a badge of honor
Forgoing sleep is like borrowing from a loan shark. Sure you get those extra hours right now to cover for your overly-optimistic estimation, but at what price? The shark will be back, and if you ca…

Sleep Is the New Status Symbol (Published 2017)
Once we would brag of not needing very much of it. Now deep slumber is a coveted state achieved with gadgets, apps, gizmos and classes.

Scientists discover how deep sleep builds muscle, burns fat, and boosts the brain
Scientists have discovered a surprising two-way relationship between sleep and growth hormone, revealing how the brain carefully balances physical recovery with wakefulness. The findings could help explain why poor sleep harms metabolism and brain health, potentially opening the door to new treatments for sleep and neurological disorders.

Sleep: Educational Impact and Habit Formation
In a field experiment among US university students, incentives for sleep increase both sleep and academic performance. Our primary intervention pairs bedtime reminders with morning feedback and immediate rewards for sleeping at least 7 hours on weeknights. The intervention raises the share of weeknights with 7+ hours of sleep by 26% and average sleep by 19 minutes during a 4-week treatment period, with posttreatment effects of 8 minutes. Immediate incentives outperform both delayed incentives and reminders/feedback alone during treatment but have no distinguishable impacts posttreatment. The primary intervention improves average semester course performance by 0.075–0.089 grade points, a 0.10–0.11 standard deviation increase. Our results demonstrate that incentives targeting sleep can be a cost-effective approach to improve educational outcomes.

The sleep switch that builds muscle, burns fat, and boosts brainpower
UC Berkeley researchers mapped the brain circuits that control growth hormone during sleep, uncovering a feedback system where sleep fuels hormone release, and the hormone regulates wakefulness. The discovery helps explain links between poor sleep, obesity, diabetes, and cognitive decline, while opening new paths for treating sleep and metabolic disorders.

The Mythical Agent-Month – Wes McKinney
Like a lot of people, I’ve found that AI is terrible for my sleep schedule. In the past I’d wake up briefly at 4 or 4:30 in the morning to have a sip of water or use the bathroom; now I have trouble going back to sleep. I could be doing things. Before I would get a solid 7-8 hours a night; now I’m lucky when I get 6. I’ve largely stopped fighting it: now when I’m rolling around restlessly in bed at 5:07am with ideas to feed my AI coding agents, I just get up and start my day.
