Your weird dreams might be good for you

Hi,

One thing nobody warns you about when you open a float center: people tell you their dreams. A lot of them. I've heard about flying, falling, and showing up to work without pants.

Turns out all that dreaming might be doing more for you than giving you a story for the front desk.

Researchers at Capital Medical University in Beijing looked at 95,559 people in the UK Biobank who wore wrist trackers for a week, then followed their health for almost nine years. The people who got more REM sleep, the dreaming stage, had a lower risk of 83 different diseases, including dementia and heart failure. Sleeping under five hours a night was tied to higher risk for 37 conditions, and the sweet spot overall landed between six and eight hours. It was published in PLOS Medicine last month.

To be straight with you, this shows a link, not proof that REM prevents anything. And a wrist tracker is making an educated guess about your sleep stages, which is a long way from a sleep lab. But it's a big group followed for a long time, and it lines up with what a lot of us feel after a bad week of sleep: everything is harder.

Here's the part I found most useful. Most of your REM happens in the back half of the night. So when the alarm goes off early, the dreaming is what you lose first.

The Weekly Reset

Here's this week's practice, the one thing I'd actually ask you to try.

Move your bedtime twenty minutes earlier for the next five nights instead of trying to make it up by sleeping in on the weekend. Same wake-up time, a little more runway. That extra stretch at the end of the night is where a lot of your REM lives.

This week's line to carry with you: My bedtime deserves the same respect as my 8am meeting.

For the ones working overtime right now

Saturday is World Mental Health Day, so this one's for everyone doing the hard work in therapy right now.

A lot of the people who float with us were sent by their therapist, and I love that.

If you're in the middle of something heavy, you don't have to rush back into your day after the hour ends. Give it somewhere quiet to land first.

More REM, lower risk of 83 diseases Capital Medical University researchers tracked sleep in 95,559 UK Biobank participants and found more REM sleep tied to lower risk across 83 conditions, with six to eight hours a night linked to the lowest risk overall. Published in PLOS Medicine, September 2026.

The sleep sweet spot for slower aging A Columbia University Irving Medical Center study of roughly 500,000 people found that both too little and too much sleep were linked to faster biological aging across 17 organ systems, with 6.4 to 7.8 hours looking best. The authors are clear it shows a link, not cause. Published in Nature, August 2026.

What REM sleep is for The Sleep Foundation's plain-language guide to the dreaming stage, why it matters for memory and emotional processing, and roughly how much of it adults need (about two hours a night).
