Learn if working out close to bedtime can cause insomnia from sleep specialist Priyanka Yadav, D.O. in this Howcast video.
So I often get asked does working out too close to bedtime
cause insomnia? And the answer is yes and no. If you are someone who is
predisposed to having insomnia, then, yes, it can cause insomnia. The
theory is that when you’re working out you’re increasing your body
temperature which is normally supposed to be dropping closer to bedtime.
And you’re also stimulated. Your body releases endorphins when you’re
exercising, and it’s really hard to come down from that high closer to
The whole sleep process begins hours before your actual bedtime. Now, if
you’re not someone who is prone to having insomnia, then exercising close
to bedtime shouldn’t be a problem at all. To those who do have a
predisposition to insomnia, I suggest working out in the middle of the day
or in the morning hours. And that will help you, in fact, sleep a little
bit better at night by promoting deep sleep.
So working out in the middle of the day or in the morning can also increase
wear and tear of your body which produces a chemical called adenosine. This
chemical is what increases deep sleep and helps sleep onset at night and is
part of your sleep process during bedtime. So whether working out close to
bedtime will cause insomnia or not really depends on different factors and
the type of person that you are.
What I suggest is if you do work out closer to bedtime and you’re having
trouble falling asleep, try working out in the middle of the day or in the
morning and see if that helps improve your insomnia.
