The millions of middle-aged and older adults who suffer from insomnia have a new drug-free prescription for a more restful night's sleep. Regular aerobic exercise improves the quality of sleep, mood and vitality, according to a small but significant new study from Northwestern Medicine.
The study is the first to examine the effect of aerobic exercise on middle-aged and older adults with a diagnosis of insomnia. About 50 percent of people in these age groups complain of chronic insomnia symptoms.
"Insomnia increases with age," Zee said. "Around middle age, sleep begins to change dramatically. It is essential that we identify behavioral ways to improve sleep. Now we have promising results showing aerobic exercise is a simple strategy to help people sleep better and feel more vigorous."
