Authors of a new study think they know—and insomnia sufferers should take note.
Back when my insomnia was chronic, I had a lot of scary dreams. They left me with a pounding heart and fear that could keep me awake for a couple of hours.

A reader—I’ll call her Chantal—wrote in June with questions about insomnia and sleep restriction. A few weeks ago I heard from her again:
I’m now in week 6 of sleep restriction and I have to say my sleep is getting better. I mostly sleep for 5.5 hours a night. When I started it was 3.

My video and blog on Sleep Restriction Therapy get lots of comments, and certain questions about SRT come up again and again. Here I’ll review the concepts behind this treatment for insomnia and offer pointers on how to succeed.
