There's now a sticker for better sleep

Hi,

Somebody at the front desk asked me last week if we could just bottle whatever it is that happens during a float and sell it. I told her science is already working on something weirder.

Engineers at UT Austin built a soft patch you wear on your skin that uses ultrasound to nudge your brain into REM sleep faster, and it apparently works. In a trial of 28 people, it got them into REM 43 minutes sooner and kept them there about 16 minutes longer, while also tracking their brain activity in real time. People said it felt comfortable. Their heart rate variability, a solid stand-in for how relaxed your nervous system actually is, improved too.

I want to be clear this isn't a product yet. It's a research prototype, tested on a small group, with the team now eyeing bigger trials for things like PTSD and chronic insomnia. But it's a strange, hopeful little glimpse at where sleep science is headed: not just more advice about screens and caffeine, but actual tools that talk to your brain directly.

In the meantime, most of us are stuck with the boring version: better light exposure, earlier wind-down, no glowing rectangle at midnight. Less exciting than a sleep sticker. Still works.

The Weekly Reset

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

Tomorrow is the equinox, officially the day light and dark split evenly, and then dark starts winning. Tonight, dim your lights an hour before bed instead of scrolling through them. You're basically giving your brain the sunset it's not getting outside anymore.

This week's line to carry with you: I don't have to fight the dark, I can just plan for it.

For the ones working overtime right now

This one's for everyone whose commute now starts or ends in actual darkness and didn't three weeks ago. Most Americans have already seen their last 8pm sunset of the year, and it only gets earlier from here. Nobody warns you how much that quietly drains your afternoon energy until you're sitting at your desk at 4:45 wondering why you feel like it's midnight.

If your 3pm slump just got a lot more aggressive, that's not a personal failing, that's just less daylight hitting your eyes. A float won't bring the sun back, but it's a genuinely good way to reset before you have to pretend to be a functional person for the rest of the evening.

Proof you're not imagining the earlier sunsets

Axios on the exact point in the calendar most of the country crosses its last 8pm sunset of the year, and why where you live in your time zone changes how much daylight you've got left.
