Why does the whole body feel weak when the weather is hot?

The vitality of the human body comes from the normal operation of various enzymes in the body. The basic process is to catabolize the food eaten at each meal to produce energy for the body to use. With energy, the human body will naturally feel energetic. With enzymes in place, this process can work properly. Enzyme activity requires a certain temperature. If the temperature is too high or too low, the activity of the enzyme will decrease, which will slow down the entire process and reduce the energy generated. Most of the human body's enzymes will exert their greatest activity at 37 degrees, which is normal body temperature. The temperature on hot days is generally above 30 degrees. However, because the human body itself will continue to generate heat, and the normal loss of heat has to pass through the interior of the human body and The temperature difference will be realized by the external temperature difference. On hot days, the temperature difference will become smaller, and the heat will not be easily dissipated from the body. If it accumulates too much, the internal temperature will rise. As a result, enzyme activity will decrease, energy production will decrease, and people will naturally feel weak.

Lack of minerals such as potassium and calcium

Summer is hot and heavy sweating will lead to the loss of calcium and potassium. Calcium deficiency leads to a decrease in the content of various troponins, weakens the contraction function of skeletal muscles, and the body will feel tired and weak. Low blood potassium can make the body feel tired, weak, dizzy and have a headache.

Therefore, you should consume more calcium and potassium in summer, especially those who like to sweat. They should eat more calcium-containing foods such as soy products and dairy products, as well as potassium-rich foods such as potatoes and mushrooms. .

Lack of B vitamins

Hot weather, sweating and loss of appetite can also easily lead to the lack and loss of B vitamins. If there is a lack of such substances in the body, people will be listless and lack energy.

So in hot weather, you should pay attention to supplement B vitamins, such as eating more whole grains such as red beans, mung beans, oats, etc., and you can also eat an appropriate amount of animal livers, such as chicken liver and pork liver. . . . . . . . . .
