Welcome to Sleep Diaries, where interesting people share a week’s worth of late-night habits. This week we have Celeste Headlee, professional speaker and author of We Need to Talk: How to Have Conversations That Matter.

Sunday: No Screens After 9 P.M.

For the past year, I’ve been working hard to try and get to bed by 10 p.m. That’s partly because my body wakes up every morning between 5:30 and 6:30 a.m., and I need 7 to 8 hours of rest. So, 10 p.m. is the magic time when I need to get under the covers.

I have a fairly constant routine: I try to stop looking at screens of any kind by 9 p.m. at the latest. If I’m not feeling tired, I’ll have a hot bath or find some other way to relax my mind. Tonight, I chose to do a 15-minute meditation designed to prepare my body for sleep. I set my phone down on the counter in the bathroom so that it wouldn’t distract me and I curled up with a nightlight and book. I was asleep by 10:30 p.m. and slept comfortably until I woke up at 5:45 a.m ... to my dog’s nose three inches from my face.
