☀️ The night shift
Last Friday was World Sleep Day (on March 13). Which is, depending on how you look at it, either a lovely reminder to prioritize rest, or a little absurd, given that sleep is the one thing most of us are already failing at without needing a calendar prompt.
We've spent decades treating sleep as the thing that happens when everything more important is done. We celebrated early rises, late nights, and grinding through for four hours. And now the same culture that glorified sleeplessness is booking five-night retreats in Switzerland to reset circadian rhythms. Plus, now hotels have sleep doctors, a smart mattress company just hit a $1.5 billion valuation, and a word game invented by a Canadian academic is going viral because our brains, left to their own devices at 2am, are genuinely not our friends.
Clearly, we are, slowly, starting to take seriously what sleep does to our mood, our mental health, and our ability to think straight.
This edition is an attempt to understand why it took us so long.

☀️ 3 Actions to Step Out of Your Comfort Zone

Find your chronotype

🧘♀️ Question of the Week for Introspection

Your curious internet friend,
