The inability to get a good night's sleep can result from waking up in the middle of the night and having trouble getting back to sleep. It also occurs when people have a hard time getting to sleep in the first place.
Insomnia can be a temporary, occasional, or chronic problem.
The effects of caffeine can last up to twenty hours, so some people will have disturbed sleep patterns even when their last cup of coffee was in the morning. Doctors of natural medicine will sometimes recommend eating a high-carbohydrate food before bedtime, such as a slice of bread or some crackers. Eating carbohydrates can significantly increase serotonin levels in the body, and the hormone serotonin is known to reduce anxiety and promote sleep. Dealing with that stress, through counseling or other techniques, may be the key to a better night''s rest. Psychological intervention has helped in many studies.
