When winter comes, the sky is cold and the ground is freezing, and the grass and trees are withering. At this moment, some people’s mood will become depressed, bored, listless, sleepy, frustrated, anxious, irritable and loss of libido, etc.; some people will even cause serious demoralization. Once the ice melts and the earth returns to spring, these symptoms will disappear on their own, and their mood and energy return to normal. This phenomenon, experts call winter depression. First, the causes of winter depression The onset of winter depression has no obvious genetic factors, the main reason for winter depression is: due to the short days and long nights in winter, sunshine time is reduced, the human body’s biological clock is not adapted to the changes in the length of sunshine time, resulting in physiological rhythm disorders and endocrine disorders, and thus appeared in the mood and mental state of the disorders. In addition, in recent years, foreign research also found that the human brain gland pineal gland is very sensitive to sunlight, when the sun is strong, the pineal gland by the sun’s inhibition, secretion of hormones less. On the contrary, when the intensity of sunlight is reduced, the pineal gland is excited, the secretion of the hormone is more. This hormone has the “ability” to regulate the level of other hormones in the body. When it secretes more, the body’s thyroxine, adrenaline secretion decreased, the concentration in the blood decreased, these two can arouse cellular excitement of the hormone reduced, making the cellular excitability reduced, become inactive, the person will be in a state of inhibition, low mood, always feel tired. The United States National Institutes of Health report, due to the lack of sunshine, the world every winter at least 5 million people suffer from “sadness”. They are often restless, love to eat strong food, and work accidents. Evidently, the prevention and treatment of depression should also become an important topic in winter. Second, which people are prone to winter depression Winter depression, also known as seasonal depression, is an affective disorder.
