Running before going to bed - bad for you?

Quote  |  Reply

I'm a busy busy college student and one of the only times I can find to work out is about 11 pm, I work out for about an hour and go to sleep between 12:30 and 1. A friend told me this is bad for me because it elevates my heart rate and it's dangerous? I would just think that would mean I was burning more calories in my sleep - I was wondering if anyone had an opinion on the matter?

Exercising late at night increases your metabolism making falling asleep more difficult. It is kind of like getting a runners high. Exercise should probably be completed 2 hours or more before bed time. However, late night exercise is better than no exercise at all. Good luck.

I brisk walk on the treadmill an hour before work 11am & an hour after work at 11pm.  I don't have any problems with it. I never heard the word dangerous before in the topic of working out before bed. I had heard that if could impair sleep because of the endorphins and adrenaline that are stirred up, but seems even that has been dismissed recently. A quick search for "exercise before sleep" brought up several articles and the ones I read were very positive about it.



I do it all the time. Its not bad for you, it just makes it hard to go to sleep. I also like to go for a run before work because it makes me feel more awake. Way better than caffeine.

I have done it at different times of the day morning, evening, late night...the only difference is as jheld and Dana makes it more difficult to fall asleep because of the endorphins being jacked up...

That's ridiculous. It's not going to hurt you, but it will make it harder to get to sleep at night. Make sure you take the time to cool down and relax before bed and you'll be fine. It's still way better to get in your exercise early, though.
