Sleep restriction therapy is growing in popularity, reports The Guardian.
Seek expert advice before deliberately depriving yourself of sleep, but the basics of SRT are simple. First, pick a fixed getting-up time – let’s say 7am – and enforce it like a fascist. Second, over a week or two, work out how much sleep you really get per night, on average. Say five hours. Now the hard part: your job is to stay out of your bedroom, and awake, until five hours before your rising time – 2am. If five hours is all the sleep you get, five hours is all you’ll have.
