In fact, spring sleep is a response to the physiological changes brought about by seasonal exchange. In the cold winter, the human body is affected and stimulated by low temperature, the capillaries of the skin contract, the blood flow is relatively reduced, the sweat glands and pores are closed, the heat dissipation is reduced, and the normal body temperature is maintained. After entering the spring, with the increase of temperature, human pores, sweat glands and blood vessels begin to relax, and skin blood circulation is also vigorous. So the blood supply to the brain will be relatively reduced. As the weather gets warmer, the metabolism is gradually vigorous, the oxygen consumption is increasing, and the oxygen supply to the brain is inevitably insufficient. Coupled with the benign stimulation of warm temperature, the brain is inhibited to some extent. So people will feel sleepy, feel sleepy, and always feel that they don't get enough sleep. However, it is worth noting that it also contains some pathological factors, and some "spring sleep" is the manifestation of the disease. For example: depressive symptoms before psychotic episode; Low fever and lethargy before hepatitis; Sleepiness caused by chronic causes such as diabetes and heart disease. Other studies have found that patients with hypertension have frequent sleepiness and yawning in spring, which is likely to be a precursor to stroke. Therefore, the "spring sleep" caused by the disease should be checked and diagnosed in hospital in time. As mentioned above, most people's spring sleepiness is an objective response to the physiological changes brought about by seasonal exchange. In order to eliminate the spring sleep, we should pay attention to the following points: First, go to bed early and get up early. With good rest and sleep in spring, the human body can be adjusted and supplemented, which further promotes the increase of anti-tension ability and reduces daytime sleepiness. Sleeping late can't increase the blood supply to the brain, but it will cause people's inertia. The more you sleep, the more sleepy you get, and the lazier you sleep. It is also worth noting that you should try not to stay up late in spring to avoid inducing and aggravating spring sleepiness. The second is to do scalp exercises. Doing scalp exercise in spring can eliminate brain drowsiness. The method is as follows: first, put your hands and fingers together naturally, and rub the whole hairline from front to back and from middle to both sides with your fingertips for 10 times; Then press it with your fingers for 3 times bit by bit in the previous order; Then use your fingers to scratch the short distance back and forth for 3 times in the previous order, and scratch each scratching area for 5 times; Finally, gently massage five times with ten fingers in the previous order. Doing 1 time every morning and night before going to bed can make you energetic and quick-thinking, which is a simple and effective way to eliminate brain fatigue and drowsiness. The third is visual stimulation. When you go out in spring, look up, give you a panoramic view of beautiful natural scenery and give yourself a good visual stimulus, which will help to eliminate spring sleepiness. The fourth is diet adjustment. Scientific diet also plays a positive role in solving spring sleepiness. Spring diet should be light, fresh and easy to digest, and vegetables, carrots, Malantou, celery, Chinese cabbage and water chestnut are the best choices. Try to eat less greasy meat to facilitate the digestion and absorption of the intestine; Eating more spicy food such as onion, ginger and garlic in moderation has the functions of eliminating dampness, avoiding filth, promoting blood circulation and exciting the brain center. At the same time, you can also eat porridge with 30 grams of raw coix seed, 20 grams of lentils, 0/5 grams of yam/kloc-,or drink tea with 20 grams of kapok and 0/5 grams of red beans/kloc-. The above methods can play a very good role in eliminating spring sleepiness. The fifth is to use the brain scientifically. Scientific use of the brain is to give the left hemisphere a proper rest. The function of the brain has different left and right hemispheres. In the daily work in spring, the left hemisphere is mainly responsible for language, mathematics, abstract thinking and so on. The right hemisphere of mental workers is less used and relatively relaxed. Therefore, when the brain is unclear and painful, we should put down our work, listen to music, enjoy flowers and do gymnastics, so that the right hemisphere can use it and let the left hemisphere rest properly. More importantly, exercise can replenish and supply the brain with the largest oxygen consumption in the human body in time, which is conducive to relieving fatigue. Sixth, brush your teeth and wash your face frequently. Brushing your teeth and washing your face is a relatively simple and effective way to eliminate spring sleepiness. When drowsiness strikes, you can brush your teeth and rinse your mouth with fragrant toothpaste, and wash your face with cold water, which can refresh your mind. Spring is a beautiful season and people's favorite sleepy season. As long as people correctly understand and take active and effective measures, they will overcome the troubles caused by spring sleep and spend the spring sleep season easily and happily.
