Vigorous exercise, late in the evening, can interfere with sleep onset. In the majority of cases, however, the core problem is emotional. Anxiety and internalized, unexpressed anger are common causes of sleeplessness. Paradoxically, insomnia may result from the use of a sedative prescribed to relieve it. There are a number of ways to help yourself fall asleep more easily.
Sexual intercourse has a relaxing effect for many people.
Relaxation techniques, including muscle-relaxation exercises and meditation, may also be useful. If these or similar tension-reducing exercises fail, it is often possible to break the cycle of insomnia by deliberately staying awake for an entire night. If insomnia is persistent, consult a doctor. Often, reassurance that the problem results from normal anxieties or from a treatable physical disorder relieves distress and helps restore a normal sleeping pattern. Many sleep problems can be overcome by simple, common sense measures.
