Regular exercise can help you sleep more soundly, but be patient. Results won’t happen overnight. Stick with it for lasting results.
If you spend your nights tossing and turning, or you take hours to fall asleep, begin an exercise plan. Regular physical activity is a wonderful prescription for insomnia. However, one sweat session on the treadmill isn’t likely to lead to better zzz’s that night. Researchers have found that, though effective, exercise is a long-term treatment for insomnia. So you’re going to have to keep at it and not get discouraged. Also, “You need to be careful about when you exercise,” says Michelle Drerup, PsyD, sleep psychologist and behavioral sleep medicine specialist at the Cleveland Clinic Sleep Disorders Center. “Remember that exercising too close to bedtime (within three hours) can interfere with sleep. Exercise stimulates your heart, brain and muscles — the opposite of what you want if you’re trying to snooze. It raises your body temperature right before bed, which can be counterproductive as well. But I still promote exercise for people with sleep problems, and here’s why: Contrary to what most people think, exercise can help you sleep longer and more soundly, plus feel more awake during the day. People who are physically fit also have better quality sleep.”
