What is insomnia? What is the common cause of it?
Insomnia is defined as trouble falling asleep, awaking in the middle of the night, or waking up early. Insomnia can be related to stress, medications, mental or emotional problems such as anxiety and depression, medical conditions such as arthritis (or any condition that causes pain), or poor pre-sleep habits such consuming alcohol or caffeine too close to bedtime as well as other sleep problems (e.g., restless leg syndrome) that prevent restful sleep. Insomnia can be temporary, occasional, or chronic.

Insomnia can be the cause of accidents.
Studies found that accidents involving motor vehicles or machine tools occurred twice as often in persons with moderate or severe daytime sleepiness, compared with those without daytime sleepiness. As many as 100,000 automobile accidents in the U.S. and 1,500 deaths from such accidents are caused by sleepiness. Experts believe that drowsy driving may account for as many automobile crashes as drunk driving.

What is Golden Triangle?
According to the Meridian Theory of Chinese Medicine, the are 3 specific "acupuncture points" on the wrist, they are Shern-Men point, Day-Ling point, and Ney-Guan point respectively.Shern-Men point is along the "Heart Meridian" which is responsible for the mental health and function of circulatory system. Day-Ling and Ney-Guan points are along the "Peri-heart Meridian" which can help prevent the hyper-function of the nervous system. These 3 specific points thus enclose a "Golden Triangle" which functions for stress-relieving and sleep-inducing.

What is the relationship between "Golden Triangle" and insomnia?
The status of blood circulation will affect Melatonin secretion by pineal gland. Nowadays, due to the stressful and tense lifestyles, biological clock is easily disturbed, and it is the main cause of insomnia. Meridian Theory of Chinese Medicine, "Peri-heart Meridian" will function effectively in 7 to 9 p.m. during this interval, the status of blood circulation is good. In addition, the optimal interval for the secretion of Melatonin is in 10 to 11 p.m. If one's biological clock has been disturbed for a long term, as a consequence, it will lead to insomnia.

Melatonin and Insomnia
Melatonin is a product of the pineal gland. Under normal conditions, Melatonin levels foreshadow the sleep cycle, usually increasing rapidly from the late evening until midnight, then decreasing as morning approaches. In this way, Melatonin helps regulate circulation rhythm, the body's 24-hour "dark-light clock" that governs the timing of hormone production, sleep, body temperature, and more.People with high levels of Melatonin usually sleep longer and more soundly than those with a deficiency. For example, the elderly, who produce less Melatonin than the young and middle-aged, are typically more susceptible to insomnia. Similarly, jet lag and consumption of alcohol, tobacco, and narcotics also interfere with production of this hormone, and thus disrupt sleep.
