Establish a regular, relaxing bedtime routine such as soaking in a hot bath or hot tub and then reading a book or listening to soothing music.
A relaxing, routine activity right before bedtime conducted away from bright lights helps separate your sleep time from activities that can cause excitement, stress or anxiety which can make it more difficult to fall asleep, get sound and deep sleep or remain asleep. Avoid arousing activities before bedtime like working, paying bills, engaging in competitive games or family problem solving.
Some studies suggest that soaking in hot water (such as a hot tub or bath) before retiring to bed can ease the transition into deeper sleep, but it should be done early enough that you are no longer sweating or over-heated.
If you are unable to avoid tension and stress, it may be helpful to learn relaxation therapy from a trained professional.
Finally, avoid exposure to bright before bedtime because it signals the neurons that help control the sleep-wake cycle that it is time to awaken, not to sleep.
