Proper use of prescription sleep medication may increase sleep. Most of these medications are only approved for short-term use. They can cause drowsiness, lightheadedness, and headache. Serious side effects can include abnormal thinking or behavior changes, including having suicidal thoughts.
Many over-the-counter sleep medications contain diphenhydramine. This medication can make you feel groggy and might help you fall asleep. However, this drug can have serious side effects. Most people should avoid using this drug regularly.
Exercise can help you get a better sleep. It can reduce stress and allow your body to reach a deeper state of relaxation. The timing of exercise is important. Exercising early in the day may be best if you are having trouble sleeping. If you have to exercise later in the day, make sure you are done exercising at least a few hours before bedtime.

This therapy may reduce or eliminate anxiety and body tension. It stops the mind from racing and allows the muscles to relax. This can support a restful sleep. The therapy may include deep breathing and progressive relaxation.
A sleep restriction program is a strict sleep program. It limits the amount of time in bed to only the time that you are actually sleeping. Previous sleep logs will determine the amount of time allowed in bed. The time you spent sleeping will be used to determine the amount of time you can spend in bed. At first, your time in bed may seem short, usually about 5 hours. Gradually, the time is increased until a more normal night's sleep is achieved.
Cognitive behavioral therapy (CBT) is a form of talk therapy. This means that you discuss your thoughts, feelings, and behaviors with a mental health professional. CBT focuses on how the way you think affects the way you feel and act. CBT may have more lasting effects than medication.
Reconditioning helps people associate the bed and bedtime with sleep. This means not using the bed for activities other than sleep and sex. As part of the reconditioning process, the person is usually advised to go to bed only when sleepy.
