How does exercise help those with chronic insomnia?
We still need to learn much more about the relationship between exercise and chronic insomnia. For instance, we do not know how exercise compares to other insomnia treatments, especially sleep medications. We also know little about what types of exercise improve sleep the most, how much exercise is needed to improve sleep, and what time of day is best for exercise to improve sleep in people with insomnia. However, from the available evidence, exercise does hold great promise for improving the sleep of those with chronic insomnia.
