Q: What is sleep restriction therapy?
A: Restricting the amount of sleep you get may sound crazy if you have insomnia, but it may help some people become more efficient sleepers.
The idea is to shorten your sleep time initially. Start with five hours in bed, say, from 2 a.m. to 7 a.m. Gradually go to bed earlier and sleep a little later. Continue until you find a satisfactory schedule. According to a study at Duke University, this method can reduce nighttime wakefulness by more than half in people with insomnia.
