In the long winter, the brain gradually gets used to working under the condition of sufficient oxygen. However, in spring, the sun shines, the temperature rises, the skin blood vessels gradually expand, the blood flow greatly increases, and the sweat glands and pores also open. However, the total amount of human blood has not increased, resulting in a relative decrease in the blood supply to the brain, insufficient energy supply to the brain, coupled with the warm climate and high humidity in spring, it has a good sedative and hypnotic effect on the human cerebral cortex, and naturally you will feel heavy and sleepy.
In this regard, shixianfang, director of the Department of traditional Chinese medicine of the Sixth Affiliated Hospital of Sun Yat sen University, said that "spring sleepiness" is mainly related to disharmony in weather, work, diet, sleep and exercise. Among them, eating hot food and turning on the air conditioner are the two "culprits". Eating too much hot food, such as spicy, fried and roasted food, dog meat, mutton, wine, hot pot, etc., can easily lead to the rise of stomach fire, the hyperactivity of yin and Yang, eye swelling and face swelling. In serious cases, it is also accompanied by flushed face and even increased anger. Internal fire is easy to damage the Qi and Yin of human body, leading to the decline of human constitution and immunity, thus affecting people's mental state and work mood, resulting in problems such as tiredness, sleepiness, insomnia, dizziness, and lack of concentration. And long-term exposure to air-conditioning environments with high levels of harmful gases such as carbon dioxide in the air will also aggravate the symptoms of "spring sleepiness".
In addition, Shi Xianfang also introduced three methods to alleviate spring sleepiness:
I. diet conditioning to eliminate inexplicable fatigue
It is easy to get sleepy when the body fluid is sour. Eat more alkaline foods, such as apples, kelp and a variety of fresh vegetables, which can neutralize the acidic substances produced during muscle fatigue and help eliminate fatigue. Foods rich in vitamins can help the human body speed up the processing of metabolites accumulated in the body and reduce fatigue. Carrots, lettuce, onions, green peppers, coriander, oranges, tomatoes, potatoes, fruits and eggs can be eaten appropriately. Caffeinated food can increase the respiratory rate and depth, promote adrenaline secretion, excite the nervous system and fight fatigue. So you can drink more tea, coffee and chocolate. In addition, we should also pay attention to eating as little cold and greasy food as possible.
Second, the best policy is to prevent spring sleepiness
Go outing for fresh air. There are many negative ions in the fresh air, which can supplement the negative charge of cells, act on the human nerve terminal receptors, regulate the central nervous system, improve the function of the cerebral cortex, and at the same time, the muscles relax and contract rhythmically when walking, indirectly driving the blood circulation, making the new and old metabolism of organs in the best state, eliminating fatigue and invigorating the spirit.
It is worth mentioning that as the temperature rises, clothes should be gradually reduced to reduce the relaxation of peripheral blood vessels. Develop the habit of regular work and rest, get up early in the morning, strengthen exercise, so as to promote and improve blood circulation, improve cardiac contraction function, make the brain get more blood supply, and improve the human body's utilization of oxygen.
III. various methods can be used to stimulate body sensation
For example, you can try acupoint massage, pressing the temple, Fengchi, Neiguan and Zusanli, first light and then heavy, once a day in the morning and evening, 3-5 minutes. In addition, pressing the inside of both thumbs helps to eliminate spring sleepiness. You can also consciously pinch your hands and feet, or wash your face with cold water.
