Why A Workout Routine Can Improve Your Sleep

Updated: Dec 21, 2021

Last month I talked about ways nutrients can improve sleep quality. Did you know that exercise plays an important factor too? Many things can affect sleep quality, for better and for worse. Exercise being on the side for better. You may be asking, why should I know how to obtain better sleep quality? Well, many people have trouble falling asleep at night. For some it may be a chronic issue, for other it may be an occasional problem. Inadequate sleep quality can have a negative impact on your energy levels throughout the day, emotional balance, and weight maintenance.

Why Does Exercise Improve Sleep?

There is solid evidence that exercise does help you fall asleep more quickly and improves sleep quality. There is not enough evidence yet to determine the best time of day to exercise in order to reap these health benefits. Because of this, it is important to listen to your body to see how well you sleep in response to when you work out.

There are two biological reasons that exercising right before bed might keep you awake:

  1. Aerobic exercise causes the body to release endorphins, which can create a level of brain activity that keeps some people awake. These people should exercise at least 1-2 hours before going to bed, allowing the endorphins time to move through their system and allow the brain to calm down.

  2. Exercise raises core body temperature. This elevation in core body temperature signals the body’s clock that it isn’t bed time. After about 30-90 minutes, core body temperature begins to decrease, and this decrease helps to facilitate sleepiness.

Even given these biological reasons, some people do not see a difference in working out earlier in the day or at night. It does not matter when you work out, you will still benefit in your sleep quality.
