Insomnia is not a disease, and no specific test can diagnose it. But it can make you feel bad, and it can affect your health. It can also be a sign of other problems.
Not getting enough sleep can affect your quality of life. It can lead to serious problems including injury, accidents, anxiety, and depression. Seek help if you think that you have insomnia.
Treatment options for insomnia:
1) Hypnotherapy-learn techniques to relax your mind and body. It may help you if you lie in bed with your mind racing.
2) Psychotherapy/Counseling/Coaching-by changing how you think. Cognitive-behavioral therapy is a type of counseling that can help you understand why you have sleep problems and can show you how to deal with them.
3) Medicines-Doctors recommend taking sleep medicines only now and then or only for a short time. They are not the first choice for treating chronic insomnia.
4) Biofeedback-EEG biofeedback/Neurofeedback is a safe, non-invasive, alternative option for insomnia. It is a tool for regulating sleep. Health professionals around the world report significant improvement in a large percentage of their clients using neurofeedback to treat chronic, long term sleep problems.
