| | | Day 8: Move More to Sleep Better | | | | Regular exercise, especially cardio, may help you sleep better and get to sleep quicker. Scientists know that it can help you keep an even mood and wind down at bedtime. When done consistently, exercise also can help you establish a healthy sleep-wake cycle, or circadian rhythm. We are still learning how it works, but people who exercise more tend to get more of the deep "slow wave" sleep that helps renew the brain and body.
The timing of your exercise may matter. When you work out, your body makes more cortisol, a hormone that helps you be more alert. It also raises your core body temperature, which also signals that it's time to be awake. If you must exercise in the evening, try to finish 1 to 2 hours before bedtime.
Tomorrow, we'll talk about how to get back to sleep when you awaken in the night. | | | | | | | | |
