I often feel sleepy in summer. What is the reason?

As the saying goes, "sleepy in spring, sleepy in autumn, hibernating and taking a nap in summer", there are reasons to want to sleep all year round. It's hot in summer, and the temperature outside is high, so the whole person seems to be sunburned, so he wants to sleep very much and often feels sleepy, which is inefficient in both study and work. Today, Bian Xiao will tell you what causes summer sleepiness.

1. What are the reasons for being sleepy in summer? 1, too tired. Many people often shut themselves in air-conditioned rooms in summer, which can not only cool down, but also improve work efficiency, so they often forget the time and often stay up late at night, so they will be very tired when they go to work during the day. For some workaholics, a lot of long-term work can easily lead to chronic fatigue. Excessive fatigue can make people feel sleepy, no matter how to rest, they will still feel sleepy.

2. Sleep too much or not enough every day. It's easy to get sleepy in summer, which may be caused by lack of sleep or excessive sleep, but many people don't know that excessive sleep can also cause drowsiness, because excessive sleep will affect the normal biological clock of the human body, so they still feel sleepy after getting up, and the whole person is listless and weak.

3, the body is short of water. Plants will wither in summer without water, and people without water will wither. If people don't drink water for a long time, they will be sleepy, because many organs in the body need water to run. If the body is short of water for a long time, the metabolic rate of the body will slow down, resulting in blood not flowing into the brain, and there will be a very strong sense of drowsiness.

Secondly, the conclusion is that the weather is hot now, and people who often work and live in confined spaces will feel sleepy because of the high carbon dioxide content in the air, but it is very normal to feel sleepy in summer, and a short rest at noon can alleviate it.
