Chronic stress is a common cause of insomnia, as is depression. The sufferer lies awake worrying instead of dropping off to sleep. This can lead to even deeper depression, to more stress and to physical ailments like stomach ulcers. If you suffer from transient or short term insomnia, there are many methods to help alleviate the problem. These range from warm baths to warm milk, herbal tea or other herbal remedies to the various relaxation techniques like yoga, visualization and meditation.
Daytime exercise is usually beneficial.
Heavy meals or sugar-laden treats late in the evening can cause stomach distress and sleeplessness. Don't drink coffee or smoke prior to bedtime as caffeine and nicotine are stimulants. Neither is it wise to use alcohol to promote sleep. This can lead to serious problems. The use of alcohol disrupts normal sleep patterns and REM sleep.
