A good night’s sleep is important to one’s physical and mental restoration. In particular it has a positive impact on memory and the functioning of the immune system. However, many people have a difficult time getting as much restful sleep as they need. Individuals with sleep disturbances can be successfully treated with hypnotherapy because hypnosis can influence the body’s processes which are very difficult to control voluntarily. It doesn’t work to just will yourself to go to sleep when life stresses are interfering with your relaxation. In fact, willing yourself to sleep and then failing actually produces more anxiety which of course is very counterproductive to sleeping. Also, many people do not want to become dependent on drugs to get to sleep every night although millions are. In contrast to many sleep-inducing drugs, hypnosis has no adverse side effects.
