Why does summer feel weak and dizzy?

Potassium deficiency in summer can easily lead to drowsiness, dizziness and listlessness. As the saying goes: "Spring is sleepy and autumn is lacking, and summer is a nap." Although this is all fatigue, the reasons are different. "Summer nap" is also called "summer burnout" in medicine. It is because of the hot and high temperature in summer that people sweat a lot, and a lot of potassium can be excreted with sweat, and potassium can not be replenished in time, which leads to fatigue and listlessness in summer. Potassium is an indispensable element in human body, and its main function is to maintain the normal functions of nerves and muscles. Therefore, once the human body lacks potassium, normal exercise will be affected. Potassium deficiency in summer not only reduces energy and physical strength, but also reduces heat resistance, making people feel tired and weak. Severe potassium deficiency will lead to acid-base imbalance, metabolic disorder, arrhythmia and muscle weakness. At this time, some people drink too much salt and boiled water in order to make themselves sweat less. But I don't know, it is easy to increase the burden on the heart and make the potassium and sodium in the body unbalanced. Pay attention to some foods with high potassium content. Among food crops, buckwheat, corn, sweet potato and soybean have higher potassium content. Among fruits, bananas contain the most potassium; Among vegetables, spinach, amaranth, coriander, rape, cabbage, celery, green onion, lettuce, fresh peas, edamame and so on. Rich in potassium and seaweed.
