You may be **shocked!!** to know that I don't fully hate sleepmaxxing 🙃 We know the basics work, and it's great people are paying attention! But the slippery slope is thinking that aggressive optimisation is necessary, when I'd rather you went out for dinner with your friends.
So follow along for sleep science that doesn't want you to be anxious 🧘♀️

I spent five years researching bedtime procrastination, and this is the most unexpected thing I found.
If you've doom-scrolled past midnight knowing you'll regret it, you're in good company! It's really common. And a lot of the standard advice (just go to bed earlier; put your phone in another room) misses what's actually going on. In this video I unpack two of my own studies [citations and links below]. I hope it's helpful :)

Wearables like the Galaxy Watch8 and Galaxy Ring can help bridge the gap between the research and our actual lives – features like Bedtime Guidance and Sleep Coaching can help to build a consistent rhythm with our sleep schedule by helping us monitor our behaviour and make the changes we want. And I like wearables to help us make small changes to sleep in a way that feels less like an uphill battle :)
