Apart from work related causes, insomnia is also the outcome of habitual consumption of alcohol, hallucinating drugs, decongestants, weight loss drugs and caffeine, nicotine and cocaine.
Treatment of Insomnia
There are some widely used medicines that go in the treatment of insomnia. However, most of these are habit forming drugs like benzodiazepines may cause severe side effects like depression and anxiety which may go against the purpose of the treatment of insomnia. Most doctors prescribe polysomnography and actigraphy, which involve an overnight sleeping test that studies the sleep pattern and the sleep behavior of the patient. This helps the doctor to understand the patient’s requirement better and accordingly prescribe a detailed therapy.
Most of the therapies advised by medical experts on insomnia are cognitive in nature and some are also stimulus based. Doctors prescribe going to bed only when feeling sleepy, not watching the television, not to have day time naps and to wake up with the help of an alarm clock even in weekends so that the patient gets accustomed to a fixed pattern of sleeping. Many also prescribe a walk after dinner or supper to lighten up the day’s load of worries and listening to music which acts as an excellent nerve relaxant too. Unwinding is an important part of the treatment to this problem.
