Generation mechanism:
On the one hand, cold makes the metabolism and physiological functions of the body in a state of inhibition and reduction, which slows down the blood circulation, causes insufficient blood supply to the brain, and causes autonomic nervous dysfunction, thus causing seasonal affective disorder.
On the other hand, short sunshine time in winter is an important cause of the disease. It is found that when night falls, the secretion of melatonin in the pineal gland of human brain increases, which affects people's mood. Light inhibits the secretion of this hormone, which leads to the occurrence of this disease.
Experts point out that people's psychology and physiology are closely related to the changes in the external natural environment. Emotional disorder in winter is caused by the cold climate and the decrease of light. So, what should I do about emotional disorders in winter? We can prevent it from the following four aspects:
The first is to strengthen nutrition. In a cold environment, the oxidation process in the body is strengthened, and the body needs high calories. The lack of vitamin C and B vitamins not only affects the cold resistance of human body, but also affects brain function and mood. Therefore, we should eat more fresh vegetables and fruits rich in vitamin C, as well as beans, milk, peanuts and animal offal rich in vitamin B 1 and vitamin B2 in winter.
? The second is to exercise. Through physical exercise, the blood flow of coronary artery is obviously increased, thus ensuring the blood oxygen supply of important organs such as brain and heart, and making people energetic. Exercise can also relieve the tension, anxiety and depression caused by autonomic nervous dysfunction.
? Third, you can listen to more music at ordinary times, so that the wonderful melody can add fun to your life. At the same time, we should participate in various recreational activities to stimulate our enthusiasm and yearning for life.
? The fourth is to get more sunshine and extend the light. Prolonging sunlight in winter can prevent and alleviate emotional disorders, which is also good for health.
