Sleep
Insomnia is a general term for difficulty falling asleep and/or staying asleep. Insomnia is the most common sleep problem, with many adults reporting occasional insomnia, and 10–15% reporting a chronic condition. Insomnia can have many different causes, including psychological stress, a poor sleep environment, an inconsistent sleep schedule, or excessive mental or physical stimulation in the hours before bedtime. Insomnia is often treated through behavioral changes like keeping a regular sleep schedule, avoiding stimulating or stressful activities before bedtime, and cutting down on stimulants such as caffeine. The sleep environment may be improved by installing heavy drapes to shut out all sunlight, and keeping computers, televisions and work materials out of the sleeping area.
Dark therapy
Dark therapy is the practice of keeping people in complete darkness for periods of time in an attempt to treat psychological conditions. The human body produces melatonin hormone which is responsible for supporting the circadian rhythms. Dark therapy blocks blue wavelength lights to stop the disintegration of melatonin and helps improve the health of human body. It can also relatively minimize headaches, chronic fatigue syndrome, insomnia, and more.
