Why winter? Does the person want to sleep very much? Tired?

After winter, some people begin to feel bored, afraid of moving, want to sleep, stay awake in the morning, lose concentration during the day, feel depressed, and lose energy at work. But I have a good appetite and a big appetite, and I especially like sweets. When winter goes and spring comes, the energy is gradually vigorous, and the drowsiness is obviously reduced, as if it were rejuvenated. In fact, this is a rare emotional disorder that occurs in winter. As soon as patients enter this season, they will feel sleepy, lethargic, overeating and gaining weight. More common in women of childbearing age. Women are more sensitive to seasonal changes than men, which is related to the imbalance of endocrine hormones in the body. Experts found that the lack of light was the cause of the disease. In winter, the days are short, the light time is short, the indoor life and work light is dark, and the nights are long, which leads to low secretion of serotonin in hypothalamus. The secretion of this substance is affected by seasonal changes, the length and intensity of sunlight.

Light is the first choice for treating diseases. Because lighting is simple and easy, there are no side effects. Choose a 40W fluorescent lamp, put it in a rectangular wooden box and come out while turning on the light. No eye diseases (retinitis, conjunctivitis), direct irradiation at a distance of 1 ~ 2m from the light source. Every morning, half an hour before sunrise and half an hour before going to bed at night. Spend more time in the sun during the day. The ultraviolet rays in the sun play an important role. Although fluorescent lamps are similar to sunlight, they are not as effective as natural light. Ultraviolet light alone is not enough, because it will harm the eyeball and skin. After a week or two of light therapy, drowsiness and lethargy can be alleviated, and then they can be irradiated once in the morning. Morning light therapy can advance the pace and enthusiasm of life and make people's activities enter normal rules. You can still shine when you sleep. This method of imitating dawn has the effect of resisting sleepiness in winter.

In addition, we can also cooperate with sports and recreational activities, such as running, playing ball and sword dancing, and Qigong, Tai Ji Chuan and dancing are also of great benefit. Drink more tea and coffee in your daily life. They contain caffeine, which can stimulate the brain.
