Why is it easy to get sleepy in summer
1. Day is long and night is short
In summer, the days are long and the nights are short, people go to bed late and get up early, have more parties, and are relatively lack of sleep. After a morning's study and work, they may feel tired. Coupled with the lack of oxygen in the brain after meals, they naturally want to doze off at noon. In summer, the days are hot and long, and the nights are cooler. Some people arrange some activities at night. In addition, the hours at night are short, so people sleep less. In this way, the biological clock is disordered, and it is easy to get sleepy during the day. Therefore, it's best to go to bed early in summer. It's suggested to insist on going to bed at 11 p.m., form the habit of taking a nap at noon and have a 15 minute rest.
2. It's hot and sweaty
In summer, the daytime temperature is too high and sweating is too much, which makes the human body sweat a lot, leading to fatigue, low spirits and sleepiness. In the case of severe high temperature operation, the human body perspires a lot and loses a certain amount of potassium, resulting in electrolyte disorder, which affects the normal operation of the human body and makes people feel tired and weak.
3. Summer phenomenon
In summer, people's appetite will be worse, or some people want to lose weight in summer. They eat too light and lack protein and other nutrients. However, our work activities and even talking will consume energy and nutrition, which will lead to negative balance of the body and make people feel weak, listless and always want to doze off.
Summer: due to physical weakness, re feel the heat of the gas caused by fatigue, vertigo, upset, sweating, or low fever and other manifestations of exogenous fever.
4. It's hot and humid
In summer, the weather is hot and humid, so it is easy to hurt the body fluid and consume gas. 'summer 'is the main Qi in summer, which is' Yang evil', and it is easy to damage the body fluid. Once the injury occurs, it is easy to produce sleepiness, fatigue, shortness of breath, sweating and other symptoms. Heatstroke state can last for a long time, might as well take some Huoxiang Zhengqi pill, avoid pestilence pill and other home medicine to improve.
In addition, in summer, there is a lot of rain and moisture, so it is easy to accumulate moisture in the human body. Especially now we all use air conditioning, a cold and a hot, often make the moisture 'turbid'. The specific symptoms are chest tightness, dizziness, body sleepiness and so on. If it's the discomfort caused by heavy moisture in the body, you can eat some dehumidified food to improve it, such as coix seed, lotus seed, red bean, etc.
5. Bad living habits
Many people's sleepiness also comes from their bad life. Especially in summer, because the day is hot and long, it is easy to go to bed late. Sleeping late, eating late at night and other habits are easy to damage the spleen and stomach. If you are particularly sleepy after a meal, it is the spleen that gives a warning. Experts say that the spleen is often associated with gastrointestinal and other organs. Once spleen deficiency occurs, symptoms such as anorexia and loose stools (thin and soft) will occur.
6. Air conditioned room waiting for a long time
It's hot in summer. People like to stay in air-conditioned rooms. However, in air-conditioned rooms, the windows are often closed, not ventilated, and carbon dioxide increases. In the long run, it will make the brain lack of oxygen, and sleepiness will invade unconsciously. Therefore, people who stay in the air-conditioned room for a long time should go out to breathe in time to supplement fresh air for the brain. In addition, the temperature of the air conditioner should not be too low, and the indoor and outdoor temperature difference should not exceed 6 degrees.
How does summer make sleepy easily to do
1. Sleep and daily life must be regular
If you want to sleep, as long as it is caused by the fatigue of all parts of the body, then the more important way to solve this problem is sleep. Sleep can relieve the tension of all parts of the body for a long time and relieve the fatigue of organs. Of course, it should be noted that staying up late is not conducive to the alleviation of fatigue of organs, but also has certain disadvantages to the body To ensure the regularity of work and rest can make the organs in a certain regular state, which is conducive to the adjustment of fatigue and reduce the state of sleepiness in summer.
2. Open windows for ventilation and air circulation
Another reason why people want to sleep in summer is that they have been in a big room for a long time, and the density of carbon dioxide is high, which leads to the relative lack of oxygen in the human brain, leading to brain fatigue. Therefore, people have a feeling of sleepiness and want to sleep. In addition, the relatively high temperature in summer makes it easier to aggravate the fatigue of the body organs. Therefore, window ventilation is very useful and can effectively guarantee the quality of life The inflow of oxygen makes the human body inhale enough oxygen, and the brain supply oxygen is relatively appropriate, which will effectively solve the problem of drowsiness caused by hypoxia.
3. Do more aerobic exercise
The reason why the human body often feels sleepy in summer, in addition to some external factors, there are also great reasons for itself. Lack of exercise, lack of anti heat and anti hypoxia ability, the body's relatively poor ability to resist the hot environment will lead to falling sleepiness and want to sleep. Therefore, if you want to solve the problem, you have to start from yourself and do more anti oxygen exercise, such as jogging and swimming Swimming and so on, can effectively improve their anti hypoxia ability, for the summer sleepiness has a very effective role in alleviating, and if you feel sleepy when to exercise, exercise can also be very effective to solve their own sleepiness oh.
4. Supplement water regularly
Water is the source of life. It's true that people really need water in summer. Due to the high temperature in summer, a large part of the body's heat dissipation method is sweat evaporation. This method can easily lead to excessive water loss, which makes the body appear hyperosmotic dehydration. Therefore, it is necessary to supplement water regularly, of course, water is the best Add a little salt, because there are many electrolytes in the sweat. If you only add water, it will cause electrolyte balance disorder in the body and affect the health of the body. At the same time, it is not recommended to drink cold water or cold water. Because the temperature is too low, there is no temperature gradient after entering the digestive tract. If you directly drop the temperature, it will cause great damage to the gastric mucosa. You do not agree with this .
5. Eat foods rich in potassium
In summer, the human body is prone to perspire, which leads to the elimination of a large amount of water and electrolytes in the body. In addition to taking electrolytes, another important component is potassium. Sodium and water can be supplemented by drinking salt water, but potassium is not good. It must be supplemented by food. For example, oranges are rich in potassium. After eating, they can effectively alleviate the electrolyte disorder in the body and reduce the blood pressure The symptoms of light fatigue, and orange is sour, which is conducive to promoting digestive function, so that people in hot weather have more appetite, and they can supplement the lost potassium by eating.
6. Try not to drink too much
Today's drinks contain many ingredients that are actually not good for human health. Although there is a lot of water in the drinks, these water phases are negligible for these harmful ingredients. Although water can help excrete the accumulated toxins in the body, the drinks can make the accumulated toxins in the body accumulate more and more. Moreover, the drinks are also rich in caffeine and other substances that can be used for food safety Although these substances have the effect of waking up, the result of waking up is more serious fatigue. This situation is not desirable, and it will also increase the burden of liver and kidney detoxification. In addition, caffeine is addictive to some extent, as I have said in my previous experience, so I don't recommend drinking any drink to wake up, which is a little different from the long-term No good.
7. The lunch was light
It's hot in summer. If you choose some fat, fried and other high calorie meat for lunch, it's easy for most of the blood to flow to the stomach for digestion, and the blood flow to the brain will naturally decrease, which is easy to cause insufficient oxygen supply to the brain, and lead to mental fatigue and lifelessness in the afternoon; Therefore, we should mainly choose some light vegetables, such as green vegetables, and then choose some fruits when we are full, which can help digestion and make brain cells get enough oxygen to make people energetic.
8. Take a walk after dinner
After lunch, if conditions permit, you can choose to take a walk in some cool places with flowers and plants. Taking a walk can help digestion, and also help people's spirit not to be tired after dinner. You can absorb enough air and oxygen outside to replenish oxygen to the brain in time, which is conducive to relieving afternoon sleepiness.
9. Wash your face and wipe with essential balm
In the afternoon, if you are really sleepy but can't rest due to various reasons, you can go to the bathroom and wash your face with cold water. When you come back, you can use essential balm to drop a few drops on your hands, rub your hands, and then rub them on your face, which can also play a refreshing role.
10. Do a health exercise
In the seat, you can gently close your eyes, do eye exercises, and then put your hands together, fingers cross each other, slowly stretch forward, and then slowly stretch to the top of the head, as far as possible to stretch no longer, similar to the action of stretching, this can also alleviate certain sleepiness.
11. Indoor planting Rosemary
A pot of rosemary can be planted in the office or beside the seat, because rosemary has the flavor of scented tea, which can enhance memory, purify indoor air, and relieve afternoon sleepiness.
