People with insomnia typically worry about not getting enough sleep. It’s easy to understand why. The media are are full of stories warning of the perils of insufficient sleep: obesity, diabetes, dementia, cardiovascular disease.
But a study of sleep in 3 traditional societies published in October suggests that humans may need less sleep than we think we do—which should give insomniacs food for thought.
“I’m on Day 4 of SRT and it isn’t going well,” Jenny wrote recently. “I finally had an appointment with a sleep therapist last week. He talked to me about SRT and gave me a 7-hour sleep window, from 11 p.m. to 6 a.m. My usual bedtime is 9:30 so I had some apprehensions. But I started 4 days ago.
“Since then I haven’t slept more than 3 hours a night. It’s really hard for me to stay up till 11, and then when I get in bed I’m wide awake! In the morning I’m so tired I can hardly keep my eyes open! Is this normal? I’m afraid I may be a treatment failure. Any advice?”
A few weeks ago I got an email from Julie, who’d written to me about her insomnia before. Here’s how she began:
“I am happy to share with you, 5 months later, that I am sleeping peacefully and soundly! It didn’t happen overnight, but my improvement did happen because of the sleep restriction you recommended!”
“This woman is persistent,” I thought, and read on. I discovered that, while Julie’s first attempts at this insomnia treatment were strikeouts, rather than give up, she found ways to modify the sleep restriction protocol so it eventually worked.
I recently attended a talk where the speaker, a photographer, posed a question to the audience. “If you took a series of photos of yourself going about your daily life,” she asked, “are there images you’d feel uncomfortable sharing with other people?”
The first image that came to mind was my face as it must look the minute I crawl out of bed after a slew of insomniac nights. That face isn’t pretty. But would signs of sleep deprivation show up in a photograph?
I recently joined a friend to watch Cloud Atlas at her home. A bad choice for evening entertainment! This is a movie where evil is lurking around every corner.
New research on laboratory mice suggests why arousing activities have such a strong impact on sleep.
