Exercise and sleep

published: 06-21-2012 Journal entry icon

It’s been commonly thought that exercise can ward off the effects of sleep loss, but it turns out that exercise only mitigates sleepiness and fatigue for an hour and doesn’t seem to have any effect on boosting performance throughout the day. Although regular exercise—both strength training and high-intensity endurance—does help you sleep better, it can’t replace lack of sleep—only actual sleep will do that. The loss of sleep affects physical performance primarily by reducing your motivation to exercise—so, when thinking about your workout plan for the week, include a plan to get enough sleep.
