Aerobic is highly recommended. It also helps to stop using cellphone or computer at least 2 hours before going to bed or at least turning down the screen brightness. A light natural music and a drop of lavender oil on the pillow also help promote a good night sleep. If the cause is stress or concern over unsolved problem, writing down the problems and solutions before going to sleep can also help. A glass of warm milk before going to bed is also recommended.
