Washington: Although exercise has been commonly prescribed for insomnia, spending 45 minutes on the treadmill for one day won`t translate into better sleep that night, a new study suggests."If you have insomnia you won`t exercise yourself into sleep right away," lead study author Kelly Glazer Baron, a clinical psychologist and director of the behavioural sleep program at Northwestern University Feinberg School of Medicine, said."It`s a long-term relationship. You have to keep at it and not get discouraged," she said.This is the first long-term study to show aerobic exercise during the day does not result in improved sleep that same night when people have existing sleep problems.
