What's with the sudden drowsiness?

Sleepiness is a temporary physiological phenomenon caused by natural climate and rising temperature. 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, because of ultraviolet rays and sunlight,

Insufficient radiation and vitamin D in the body reduce the immunity and working ability of the body. 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 "sleepiness fatigue".

Although sleepiness is not a disease, it will also affect people's study and work. For example, students who are under great learning pressure, busy white-collar workers, drivers who need to concentrate, etc. Sleepiness is a very distressing thing for them.

How can people stay away from drowsiness?

Some people think that as long as they sleep more every day, they will not feel sleepy, but they are 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 practice can prevent drowsiness from the following three points:

Method 1: The rhythm of life should be regular.

To overcome sleepiness, we must first grasp the rhythm of life, don't stay up late to study impulsively, go to bed early and get up late, and develop more regular living habits.

Practice has proved that it is the key to relieve sleepiness to adjust the living habits formed in winter and make the body gradually adapt to the climate with rising temperature. 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 the spring of the earth, everything is revived. We should go outdoors more and do some proper fitness exercises, which can effectively improve physiological functions, increase human respiratory and metabolic functions, accelerate internal circulation, increase oxygen supply to the brain and relieve drowsiness. 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

According to modern medical research, sleepiness is related to protein deficiency, acidic environment and insufficient vitamin intake. Therefore, attention should be paid to increasing protein's intake during spring sleep, 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 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 drowsiness.

In addition, nutrition experts also made the following suggestions:

Don't eat too much three meals a day. It's best to eat three to five meals a day, otherwise the stomach will swell excessively and people will be sleepy easily.

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.
