Spring health preservation: it is a temporary physiological phenomenon caused by natural climate and rising temperature to fight against spring sleepiness and drive away fatigue. It turns out that in the cold winter and early spring, people are affected by low temperature, and the sweat glands of the skin contract, reducing the heat emission in the body and keeping the body temperature constant. In spring, the temperature rises, the skin pores stretch, the blood supply increases, and the oxygen supplied to the brain decreases accordingly, which affects the work of the brain and makes the biological clock less accurate. In spring, the sun is warm, and the magnetic field strength increases, so the body naturally responds to these. In winter, due to the lack of ultraviolet rays and sunlight, the body lacks enough vitamin D, which reduces the body's immunity and working ability. In addition, the intake of vitamins is also less, so spring is coming, and most of the body functions are in a semi-lethargic state. So at the turn of winter and spring, we are particularly sensitive to weather changes. Some people call it "spring sleep". Although spring sleep is not a disease, it will also affect people's study and work. For example, students who are under great study pressure, white-collar workers who are busy at work, drivers who need to concentrate, etc. Spring sleepiness is a very distressing thing for them. So with the coming of spring, how can people stay away from the spring sleep? Some people think that if you sleep more in spring, you won't feel sleepy, but it's not. Under normal circumstances, adults can sleep about 8 hours a day. Increasing sleep may reduce the excitability of cerebral cortex and make it in a state of inhibition. People will get more and more sleepy, listless and sleepy as they sleep. Scientific methods can prevent spring sleepiness from the following three points: method 1: the rhythm of life should be regular and overcome spring sleepiness. First of all, we should grasp the rhythm of life. If you want to study for three days on impulse, don't stay up late, go to bed early and get up late. You should form more regular living habits. Practice has proved that adjusting the living habits formed in winter and making the body gradually adapt to the climate of rising temperature in spring is the key to relieve spring sleepiness. For example, in order to keep warm in winter, the door is usually closed, and in spring, the doors and windows should be opened frequently to make the indoor air unobstructed; We should also pay attention to ensuring a certain amount of sleep time in our daily life. Adequate sleep helps to eliminate fatigue. Method 2: Exercise more in spring. When everything recovers, you should go outdoors and do some proper physical exercises, which can effectively improve physiological functions, increase the body's respiratory and metabolic functions, speed up the internal circulation and increase the oxygen supply to the brain, so that the drowsiness in spring will be alleviated. For example, taking a walk in the morning, doing exercises, running and playing Tai Ji Chuan are all very conducive to refreshing. Method 3: Diet Conditioning Modern medical research believes that sleepiness in spring is related to the lack of protein, acidic environment and insufficient vitamin intake. Therefore, in the spring, we should pay attention to increasing protein's intake, such as appropriately increasing fish, eggs, milk, bean products, pork liver, chicken, peanuts and other foods. "When spring comes, the taste should be sour and sweet, so as to nourish the temper", so when spring comes, we should pay attention to eating more alkaline food, neutralize the acidic products in the body and eliminate fatigue. Don't eat cold, greasy and sticky food, and don't drink too much. It is best to eat more fresh vegetables and fruits every day. Vegetables contain more alkali, so eating more fruits and vegetables is ideal for improving spring sleepiness. Increase the intake of vitamins. For example, vitamin C has the function of making intercellular adhesion substances, which is very helpful for the repair and growth of human cells; B vitamins can prevent nervous system dysfunction and eliminate mental stress. Therefore, eating more foods and vegetables rich in vitamins has a positive effect on relieving spring sleepiness. In addition, nutrition experts also put forward the following suggestions: don't eat too much for three meals a day, and it is best to eat three to five meals a day, otherwise the stomach will be too bloated and people will easily feel sleepy. Many people don't eat breakfast in the morning, which will lead to insufficient sugar supply in the brain, difficulty in concentration and drowsiness. In fact, a glass of milk and some pieces of bread for breakfast are a good choice. But it is best not to drink milk on an empty stomach, and it must be accompanied by starchy food. Zinc deficiency will affect cognition and concentration. Seaweed, kelp and other seafood are rich in zinc and are suitable for eating 1-2 times a week. When the spring sleep attacks you, how to drive it away? The following are some practical methods: Method 1: When you feel sleepy, brush your teeth and rinse your mouth with fragrant toothpaste, and wash your face with cold water to improve the excitement of the nervous system, so as to achieve the purpose of eliminating spring sleepiness. Method 2: Go out to the suburbs, lakes, springs, beaches and hilltops by visual stimulation, and look up. If you look forward to staying indoors for a long time, you can also add some colorful and energetic decorations and flowers indoors, giving people a pleasing feeling; Good visual stimulation is conducive to eliminating spring sleepiness. Method 3: Taste stimulation: Eat some bitter and spicy food, or soak a cup of strong tea or coffee to relieve drowsiness. Method 4: When the sense of smell stimulates drowsiness, you can smell wind oil essence, cool oil, toilet water and lit sanitary incense, which can drive away drowsiness and cheer up the spirit. If we can adjust measures to local conditions, planting some fragrant and refreshing seasonal flowers and plants in the living room, balcony or courtyard will also help to relieve boredom. Method 5: When you are sleepy due to auditory stimulation, you often listen to some music or songs with beautiful and lively tunes, which are inspiring and inspiring, so as to please your body and mind, or enjoy some cross talk, sketches, jokes and comedies, so as to excite your nerves while getting laughter and drive away your drowsiness. Method 6: When limbs are sleepy, moving limbs can relax muscles, promote blood circulation, dredge joints and make the brain excited.
