It's hot and sleepy

From the point of view of western medicine, it is easy to get sleepy in summer, because the temperature is high in summer, the skin blood vessels and pores of human body will expand, so the diameter of blood vessels will become larger. In this way, the blood flow of the skin increases, so the blood supply to the brain will be relatively reduced, and people will easily fall asleep.

Furthermore, the metabolism in the human body is accelerated in summer, and the demand for oxygen in the body is increased. If the brain can't adjust the demand for oxygen in time, then the body will feel very tired and sleepy.

In summer, due to the increase of body perspiration, many trace elements will be excreted with sweat stains. If you don't supplement the trace elements needed by your body in time, you will feel tired and depressed.

From the perspective of Chinese medicine, there are several reasons.

First, hot and humid. Although the temperature is very high in summer, the humidity is actually the heaviest. If the body is weakened by the spleen and stomach, damp heat is more likely to accumulate in the body, resulting in damp and turbid qi.

Sweating a lot in summer, coupled with the heavy humidity in the air, can easily make people feel groggy and affect their study and work efficiency.

Second, the accumulation of cold air. Because everyone likes to eat cold food in summer, especially children, who like to eat ice cream and cold drinks. But these foods are wet and cold, and eating too much will make people feel heavy and sleepy.

Third, the spleen and stomach are weak. Want to turn food into qi and blood, occupies a very important position in the spleen and stomach of traditional Chinese medicine. If the spleen and stomach are bad and exceed the burden, then these foods will accumulate in the body, and finally turn wet into heat and phlegm.

But in summer, because of eating ice and other reasons, the function of the spleen and stomach will also be weakened. Therefore, if you want to have a good mental state in summer, strengthen the spleen and nourish the stomach and get rid of dampness, these are the key points.
