Edition #52 is live, and it's about sleep. Or rather, why we've been so bad at it 👀

This week, I went down a rabbit hole that started with World Sleep Day (yes, it's a thing) and ended somewhere between Swiss sleep retreats and a word game that mimics the brain's natural drift into unconsciousness.

A few things I didn't expect to find:

• Hotels now have sleep doctors and overnight brain monitoring programmes, and a smart mattress company just hit a $1.5 billion valuation. Sleep has quietly become a luxury category.

• Stanford Medicine researchers found that it's not just how long you sleep, but when. Your bedtime timing may matter more for your mental health than the number of hours.

• A Canadian academic developed a technique called cognitive shuffling, which went viral on social media. The idea is to mimic hypnagogia, the transitional state between wakefulness and sleep, to trick your brain into switching off. Sleep specialists are paying attention.

The word of the week is hypnagogia, the name for that strange borderland where faces appear, and you hear someone call your name right before you fall asleep. Most of us have been there without knowing it had a name.

Are you someone who protects your sleep, sacrifices it, or is still somewhere in between?
