Will Working Out at Night Disturb My Sleep?

When I would have sleepovers as a kid, my mom would always tell us that we were not allowed to run around like monkeys before bed because then we would not be able to fall asleep. Being the angelic child that I was, my friends and I would start doing jumping jacks as soon as mom left the room in hopes of staying up all night long, only to be asleep soon thereafter. Turns out mom was wrong (sorry mom) -- I have never had any hard evidence against it, until I dug a little.

A professor from the University of South Carolina, Shawn Younstedt who researches physical activity and sleep, says that evidence indicates that [evening exercise] does not disturb sleep for most people. Furthermore, any initial sleep disturbances may resolve within a few weeks. This is great news for any of you that work crazy hours but still want to fit in a workout. You may have always felt you couldn't do it right before bed because it would mess up your sleeping patterns but that should no longer be a worry.

This also gives further evidence that 24 hour gyms are not so crazy after all, now are they.

I've been working out in the morning since I've had night classes the past four years. I start work at the end of the month though and I don't think I'll be able to get up that early so this is very good news. I'm usually tired after exercising in the morning anyway :P

I'm not a morning person so I usually workout in the evening. Whilst working out in the morning leaves the evening free to do whatever, I find that my evening workout really helps get rid of workday stress and, once I've had a shower, I feel nice an relaxed and ready to sleep. I've often read that working out in the morning is supposed to be better and improves your metabolism and stuff, so I've always felt that I wasn't doing the best I could for myself, so this makes me feel better about it.

This could be ideal for me. For the last month, I've been using flex time to run home in the middle of the day, workout, shower, and go back to work. I'm not good at getting up before about 7 or 8 and the baby either needs to be in daycare or asleep in order for me to workout. So maybe if I can get her to go to sleep early enough, I could fit in a workout at night. Of course, then I have to choose to miss some t.v. and I love me my 7-10pm t.v.! Choices, choices!

Interesting article and so relevant for me! I've had to switch round my exercise times because of exams so I'm just fitting in workouts whenever I can. Last night I decided it would be a hot idea to run on the treadmill at 11:00. I felt great after...problem was my energy continued waayyy into the night/morning! I finally got to sleep at 4:30 and woke up very grumpy and tired at 7:00 a.m. Hmmm...lesson learnt I think!

maybe your mum was double bluffing, maybe she said 'don't jump around you won't be able to sleep later' bacause she knew you would jump around and that it would make you all tired and sleepy. clever mum.

I usually exercise later at night, after dinner in the minimal amount of time that I have before bed and I've never had a problem sleeping after that. Usually just makes me more tired!
