For those who have battled insomnia, the idea of deliberately losing more sleep might seem counterproductive. However, research indicates that sleep restriction therapy can be a powerful tool against chronic sleep issues. A comprehensive review of 20 studies, featured in The Annals of Internal Medicine, highlights that this therapy is just as effective as medication in addressing sleep disorders.
New York Magazine explains that sleep restriction therapy falls under CBT-I (cognitive behavioral therapy for insomnia), a method designed to alter thought patterns and behaviors. CBT-I includes various techniques, such as relaxation exercises and consistent sleep routines. While sleep restriction may seem unconventional, studies show it can yield significant improvements in sleep quality.
Simply staying awake won’t resolve insomnia on its own. Instead, sleep restriction therapy involves meticulously tracking actual sleep hours over several weeks. Patients then align their sleep schedules with these recorded hours, not their ideal sleep duration. For example, someone averaging six hours of sleep would plan to sleep only six hours nightly. As their sleep improves, they gradually extend their sleep window until reaching a full seven to eight hours.
Dr. Michael Perlis, director of the behavioral sleep medicine program at the University of Pennsylvania’s Perelman School of Medicine, explained to New York Magazine that sleep restriction therapy focuses on a key insight: "People often fixate on the total hours of sleep they get, but what truly frustrates them isn't the six hours of rest—it's the time spent lying awake, staring at the ceiling, waiting for sleep. That's the real issue we aim to eliminate."
Sleep restriction therapy works by aligning the time you spend in bed with the time you actually sleep. Initially, this might mean even less sleep than usual, as many with insomnia take hours to fall asleep. However, the goal is to build up enough fatigue so that you begin to fall asleep faster. As New York Magazine notes, "By the time you reach your pillow, you're so exhausted that you drift into a deep sleep, helping your brain associate the bed with restful sleep over time."
While sleep restriction therapy is effective, it’s not an easy process. It can be physically and mentally taxing, and despite its proven results, many patients drop out once they understand the commitment required. Perlis noted, "As soon as they realize what’s involved, they often quit." Yet, for those who stick with it, enduring a few weeks of sleep deprivation can lead to a more peaceful and restorative future.
