It would make sense… You work out aggressively and then are worn out later that night and so you sleep great. However, is it true? Does exercise make you sleep better?
As it turns out the short-term impact of exercise (how it makes you sleep that night) is positive, but minor. One meta analysis found that exercise had no effect on wakefulness during the night but reduced the time it took to fall asleep and increase total sleep time by 10 minutes. Here’s the full results:
What about people suffering from insomnia? Another study had sedentary participants who were suffering from insomnia either continue to be inactive or exercise for 30- 40 minutes, 3 to 4 times a week on a treadmill or stationary bike. The researchers found that exercising didn’t predict better sleep that night. It is also important to note that there may be other reasons that you suffer from insomnia. For example, you might struggle with anxiety before you go to sleep. If this is the case then you should look to using something like Neoteric Nutra cannabidiol oil which is a CBD product that can help you get to sleep quicker and have a better night’s sleep. Exercising will help you get to sleep quicker, but it might not be so helpful in improving the quality of your sleep. That’s why it’s a good idea to have a look at other options that are out there.
But, what’s the long-term impact of exercise on sleep? Over time, exercise increases total sleep time, reduces the amount of time it takes to fall asleep and reduces wakefulness during the night. Here are the full results:
When it comes to patients suffering from insomnia, the researchers found that the patients slept longer (1.25 hours more), fell asleep faster, experienced higher quality sleep, and had less depression symptoms, less sleepiness and more vitality during the day after 4 months of exercise.
Exercise will improve your sleep, but it can take time. When it comes to timing, the meta analysis found that participants went to sleep faster and woke less in the middle of the night if exercise was done 4 to 8 hours before bedtime. But, exercising at any time of day should improve your future sleep. So keep up the exercise!
