Physical exercise generally improves sleep for most people and helps sleep disorders, such as insomnia. The optimum time to exercise for sleep benefits is four to eight hours before bedtime.

Step-by-step explanation:

Research shows that physical exercise generally improves sleep for most people and helps sleep disorders, such as insomnia.
