What should I do if I am sleepy in class? I beg my predecessors on my knees.

First of all, adjust your work and rest schedule. You must combine work and rest. You stay up too late at night and go to class and sleep during the day. In fact, you have picked sesame seeds and lost watermelon.

Watson's has a mint cream sold in Mentholatum. It is very effective when applied to temples to relieve sleepiness, but it is not easy to buy. You can ask your parents to watch it often, because it will be sold out every time it comes to the counter, and you can't buy it for a while. You can also use wind oil essence. You can also prepare some chocolates, bayberry, jujube and so on, which can refresh you;

Here are some foods to relieve fatigue:

Spinach contains magnesium, a mineral that women are easy to lack. If the daily intake of magnesium by women is less than 28 mg, people will feel tired. The function of magnesium in human body is to convert carbohydrates in muscle into usable energy.

Bananas are called high-energy foods, which contain carbohydrates easily absorbed by the human body and are also rich in potassium. Potassium can help maintain the normal function of muscles and nerves in the human body, but it can't be stored in the body for a long time. After strenuous exercise, the potassium in the body will drop very low. Studies have shown that too low potassium can lead to muscle pain, arrhythmia, slow response, etc., and eating a few bananas can supplement the lack of potassium.

Strawberries are rich in vitamin C, which helps people absorb iron and nourish cells, so eating more strawberries can make people energetic.

cereal some people find that if the fiber content in breakfast is high, you won't feel hungry. Nutritionists explain that fiber can slow down digestion, continuously supply carbohydrates to blood vessels, and make the human body get energy continuously. Oatmeal is a kind of food rich in fiber, and its energy release is slow and balanced, which can keep the blood sugar level of human body at a high level all the time, so it won't feel hungry and full of energy soon.

In addition, several methods of Chinese medicine are introduced:

I feel limp when I come to work in the morning, and I yawn before I get off work. This is because in the cold winter and early spring, the sweat glands of the body's skin are stimulated by the cold, reducing heat dissipation to keep the body's body temperature. In spring, the temperature also rises slowly, everything recovers, the skin pores relax, and the oxygen supply of the brain decreases accordingly, so people are prone to fatigue. Generally speaking, the need to refresh themselves in spring is caused by the excessive seasons, which has a certain impact on our work and study, so we should take action quickly.

n strategies of Chinese medicine to solve mental fatigue

Chinese medicine has always been considered as a relatively harmless treatment. To refresh yourself, Chinese medicine has various countermeasures, depending on your personal preferences. Let's introduce three main methods of refreshing yourself.

Mint tea can stimulate the movement of food in the digestive tract and help digestion, especially suitable for gastrointestinal discomfort or eating too greasy food. Office workers who work in front of the computer should drink a cup of cool mint tea when they feel depressed, which is conducive to refreshing their minds and relieving stress.

Lemon has the functions of diuresis, promoting digestion and blood circulation, and relieving headache, and its faint fragrance can make people feel refreshed, but pregnant women should not drink tea containing lemon.

Strategy 2: Medicine incense drives away fatigue

You always feel listless and inefficient in spring, but you just don't like the refreshing tea that needs to be brewed every day. What should I do? Never mind, you can make your own sachet, just wear it on your body or put it next to your desk every day.

Simple making recommendation of sachet: Take 3 grams of Borneolum Syntheticum and Camphor, 15 grams of Alpinia officinarum and 3 grams of Cinnamomum cassia, mix and mash these four kinds of traditional Chinese medicines, sew the cloth for making sachet into small bags, and put them into the prepared medicine. After a period of time, if the smell in the sachet may weaken and the refreshing effect will also decrease, you should replace it at this time.

Efficacy: The principle that the sachet can refresh people is that the unique aroma of traditional Chinese medicine in the sachet acts on the brain or nasal mucosa to regulate the nervous system and make people refreshed. According to the research, the fragrant smell emitted by the medicine in the sachet can stimulate the nasal mucosa and increase the content of antibody-secreted immunoglobulin A(SlgA) on the nasal mucosa. The increase of its content makes it difficult for the virus to survive on the nasal mucosa and respiratory mucosa, thus greatly reducing people's chances of catching a cold. Strategy 3: TCM self-massage

1 Massage the head and temples

Massage method: massage the upper and lower eyelids with four fingers together, and then massage. When you massage, it is best to be emotionally stable, chest out and abdomen in order to achieve certain results.

Efficacy: We are familiar with the temple. The correct position of the temple is about one-third from the brow tip to the ear. Touching the most sunken part with your hand is the temple. Massage the temple often can promote the blood circulation of the brain and relieve fatigue, and the operation is very simple, so it is suitable for doing at any time.

2 Massage Yongquan point on the sole of the foot

Massage method: First of all, choose the right point. Yongquan point is what we often call the center of the foot, which is at the bottom of our foot and the middle point of the second metatarsal space. It is equivalent to the junction of the front 1/3 and the middle 1/3 of the palm of the foot. The massage time is best before going to bed every night. The massage methods include shiatsu and rubbing, and each time is about 5-1 times, mainly due to the fever of the foot.

efficacy: this point is the starting point of kidney meridian of foot shaoyin. Kidney governs the storage of essence, which has the physiological functions of absorbing, storing and sealing essence, and is in charge of the growth, development and reproduction of human body. Massage at Yongquan point, through the transmission of meridians, can make the kidney have a good effect, regulate endocrine and autonomic nervous system, and refresh the mind.

three common wrong ways to refresh ourselves

There are many incorrect ways to refresh ourselves in life, which can indeed restore our energy to some extent, but what will be the effect if we use these methods to drive away fatigue for a long time?

1 Use alcohol and tobacco to refresh oneself

Alcohol and tobacco can refresh oneself, which is undeniable. The main mechanism is to stimulate the cerebral cortex through certain chemicals in alcohol and tobacco, so as to keep the brain excited, perhaps occasionally, but it is not the right way to eliminate troubles and fatigue for a long time. Long-term smoking and drinking will not only bring great harm to your body, but also reduce people's immunity, distract their energy and make them more prone to fatigue.

2 As long as you sleep more, you will naturally feel good.

Being listless in spring is not because people's sleep time will be correspondingly prolonged in spring, but because they can't adapt to the climate change at once. People's sleep time has a scientific category. Adults sleep for about 8-1 hours a day. If they sleep for too long, the cerebral cortex will be in a state of inhibition. It seems that you can't sleep, but your mind is groggy.

The best suggestion is that you get up early every day to exercise. The temperature in spring is suitable for getting up early, and after exercise, you can get rid of some inertia, improve your immunity and be refreshed.
