Why do people feel sleepy in the summer?

As the saying goes: "Spring sleepiness, autumn fatigue, summer nap". While this is all part of fatigue, the causes are different.

"Summer nap" is also known as "summer burnout" in medicine, which is due to the hot summer and high temperature, which makes the human body sweat a lot, and a large amount of potassium can be excreted with sweat, and because potassium is not replenished in time, it leads to fatigue and lack of energy in summer. Potassium is an indispensable element in the human body, and its role is mainly to maintain the normal function of nerves and muscles. Therefore, once the body is deficient in potassium, normal exercise will be affected.

Potassium deficiency in summer not only reduces energy and physical strength, but also reduces heat tolerance, making people feel tired and weak. When potassium deficiency is severe, it can lead to acid-base imbalance, metabolic disorders, arrhythmias, and general muscle weakness in the human body. At this time, some people drink too much salt water in order to make themselves sweat less.

But I don't know that doing so is easy to increase the burden on the heart and make the body lose potassium and sodium.

In summer, due to the fact that people go to bed late and get up early, they may feel tired after a morning of study and work, and the brain is deprived of oxygen after meals, so they naturally want to doze off at noon. In addition, the temperature is high during the day, sweating a lot, physical exertion is too large, and the scorching sun is in the sky at noon, at this time, the blood vessels of the human body are dilated, and the blood supply to the brain is reduced, so I often feel sluggish and drowsy.

The reason why it is easy to get sleepy in summer is most common for the following reasons:1In summer, the weather is hot and the humidity is high.

The dilatation of peripheral blood vessels and capillaries in the human body increases the blood supply to the periphery, resulting in a relative decrease in the blood supply to the brain, which is prone to symptoms of sleepiness. 2.When the organs of the human body work in a hot environment, the oxygen consumption will increase relatively, which is easy to cause sleepiness in summer.

3.In the hot summer, the temperature is generally high, and the same is true at night, the human liver fire is more vigorous, and the quality of sleep at night generally declines, resulting in easy sleepiness during the day.

There are many factors that cause sleepiness in summer, first, the temperature is relatively high in summer, the pores of the face are stretched, the blood supply bar increases, and the human brain is harmed, so it gets rid of the usual biological clock and is easy to sleepy. Second, it is very easy to increase the stomach fire in summer, and the liver fire will interfere with people's mental outlook and work mentality, causing fatigue, always wanting to sleep and other diseases. Third, the human body in summer has to bear the load of high temperatures, which leads to the physical and mental exhaustion of various physiological organs of the human body, so people have to become more and more energetic and easy to sleepy.

Many people are sleepy in summer, and when the temperature is hot, especially in summer, they often feel that they are sleepy and tired, and their appetite will be reduced. Because the temperature is very high in the summer, it can lead to excessive perspiration of the human body, which can lead to a decrease in the blood volume of the human body, and the situation of listlessness and sleepiness will occur. If you sweat too much, it will also cause some elements in your body to flow out.

For example, after the outflow of zinc, the normal operation of the human body will be harmed, then people will experience weakness and fatigue, and there will also be high temperature conditions, people's gastrointestinal problems will also occur, mainly manifested as weak stomach, and there will also be some major manifestations such as sleepiness, or insufficient blood flow to the human brain after eating, mainly manifested as fatigue.

If you are sleepy in summer, you may think that it may be due to the hot weather and high temperature in summer, which leads to an increase in the body's perspiration. If you fail to pay attention to timely hydration, it is easy to lead to a decrease in blood volume in the body, resulting in a relative lack of blood supply and oxygen supply to the brain, and the phenomenon of sleepiness will occur, which can also be accompanied by mental fatigue and physical fatigue. It may also be due to the fact that the weather is too hot in summer, if you stay in a high temperature environment for a long time, the oxygen consumption of various organs of the body increases, resulting in relative ischemia and hypoxia of the brain, which can cause sleepiness.

In addition, it may also be caused by the long days and short nights in summer, and the daytime is relatively long in summer, and if you often stay up late at night and lack of sleep, you will be prone to sleepiness during the day.

It is easy to get sleepy in summer, mainly because the weather is very hot, and a large amount of water in the human body is discharged, that is, sweating a lot, which increases the consumption of potassium.

In summer, the weather is hot, and people sweat a lot, so they are often tired easily. In summer, the days are relatively long, so you need a lunch break to replenish your body's energy.

In summer, due to the hot weather and the temperature is too high, it will increase the amount of sweat that people sweat, which will cause the human body to be tired and listless, and want to sleep.

Hello. Yes. Sleepy in spring, lack of autumn in summer, napping in summer. This is normal. Usually pay attention to exercise more. It might be better to strengthen your physique.

This is normal, the so-called summer nap, as long as you are free to sleep, it is recommended to control the time, do more exercise, wash your face with cold water, can be alleviated.

In summer, it is easy to be sleepy, mainly because of the weather: first, the weather is hot, and second, the weather is humid.

In any case, symptoms such as fatigue and sleepiness in summer indicate that the body is in an unhealthy state, and some sleepiness is due to the fact that the body is in a sick state, so don't be indifferent.

Spending a lot of time in an air-conditioned room can also be a cause of sleepiness in the summer. In air-conditioned rooms, the windows are often closed, not ventilated, and carbon dioxide increases, which will deprive the brain of oxygen in the long run, and drowsiness will invade unconsciously. Therefore, people who stay in air-conditioned rooms for a long time should go out at the right time to breathe and replenish fresh air for their brains.

As the saying goes, spring is lacking, autumn is sleepy, and summer is napping. When it comes to summer, people always feel listless and have no energy. Today, I would like to share a few tips with my friends.

It is due to the lack of oxygen, which causes sleepiness.
