Exercising At Night Will Keep You Up! True or False?

October 19, 2012

Many believe that exercising at night time can mess up with sleep, as it might give an energy boost that interferes with bedtime.
But that’s not entirely correct...

It’s true that workouts stimulate your metabolism, and raise your body temperature as well (where a cool body temperature helps to induce sleep). Even though you’ll feel energized immediately after a session, cooling down from a workout triggers your brain to release melatonin, which can help you fall asleep.
The best thing is to make sure to wrap up the routine at least one hour (two is ideal) before going to bed, so that you have the time necessary to relax, and get your body into sleeping mode, as clearly explained by Michael Breus, Ph.D., author of The Sleep Doctor's Diet Plan: Lose Weight through Better Sleep.
In other words, even if you have to work until late, you still have the opportunity to enjoy a good workout (instead of just collapsing in front of the TV) without worrying that it might mess up with your sleeping routine!

The Iron You


  1. Well technically, if you are exercising at night, then you are actually up anyways! So this is obviously true!

    But if you mean evening exercise might cause insomnia, then that is plausible based on many factors; type of exercise, intensity, body type, recovery ability, pre/post workout nutrition, etc... however some exercise (yoga, meditation, flexibility routines) may relax and improve the quality of sleep!
