Winter is the fourth season of the year in some areas. As the weather turns cold (except in equatorial areas), it means silence and desolation in many areas. When the cold current strikes, living things will reduce their life activities, many plants will shed leaves, animals will hibernate, and some are called hibernation. Migratory birds will fly to warm places for the winter.

After autumn, the weather turns cold and everything is bleak. Affected by the natural environment, people's metabolism slows down, and they are prone to depression, which is called "sad autumn" by the ancients in China and "seasonal emotional disorder" by western medicine. The British "Mirror" website published an article, and doing the following little things can keep you in a good mood in autumn and winter.

1, often bask in the sun. In autumn and winter, the sunshine time is short and there is no sunshine, so people are prone to depression and fatigue. A simple and effective way is to go outdoors for 30 minutes before 10 every morning. Even if the weather is not clear enough, the outdoor light intensity is 500~ 1000 times that of indoor light. Studies have shown that morning sunshine can regulate the body's biological clock and prevent depression.

2. Regular daily life. In autumn, people often feel that they are still very tired after waking up in the morning and wish they could sleep for a while. I advise you not to lie in bed even if you are sleepy. Staying in a dark room for a long time will increase the secretion of melatonin and make people feel sleepy during the day. The best way is to sleep and get up on time every day.

3. Eat scientifically. Lack of sunshine in autumn will reduce the secretion of serotonin, a happy hormone. Due to the lack in the body, we will want to eat some foods that can promote serotonin secretion, such as pasta, potatoes, rice, etc., but these foods will make us gain weight quickly.

It is recommended to eat Chinese cabbage, sweet potato and pumpkin, which are rich in vitamin C, plant fiber and antioxidants, which are beneficial to the mood; Pears, apples and other fruits are good for the heart, and you can also eat more.
