After strenuous exercise, people often feel very tired, tired and weak, and at the same time their energy will drop, making people lose their appetite. Some people feel physically and mentally exhausted because of the fast pace of life and too much mental stress, and at the same time they will be lazy and weak. At this time, if we pay more attention to the food rich in B vitamins, active enzymes and minerals, it will be very helpful to restore physical strength and spirit, among which bananas are the most recommended anti-fatigue food.

When people are exercising, especially when they take part in high-intensity exercise, the energy in their bodies needs to be continuously consumed and their body temperature will rise. In order to maintain the balance of the body, the human body needs to discharge the products of tissue metabolism in time and emit excess heat, so people need to sweat a lot.

In this way, the human body not only excretes a certain amount of water and salt, but also excretes a certain amount of minerals with sweat, of which potassium is a more important one. However, potassium plays a very important role in the human body. It can maintain the normal osmotic pressure inside and outside human cells, participate in the metabolism of tissues and cells, and enhance the excitability of nerves and muscles, especially for ensuring the normal contraction and relaxation function of human myocardium. Once the human body is short of potassium, it will feel weak in limbs and whole body, and its physical strength and spirit will decline. If potassium deficiency is serious for a long time, it will also lead to dizziness, palpitation, general muscle weakness and even arrhythmia, dyspnea and other serious symptoms.

When you feel tired, it is necessary to supplement potassium properly. Bananas are rich in potassium, which can replenish potassium urgently needed by human body in time. Bananas are also rich in sugar, which is an important source of tryptophan, vitamin B6 and magnesium. These can not only effectively supplement sugar, but also help the brain to produce serotonin, which is of great significance for eliminating nervous system fatigue and regulating hormone system function. In addition, bananas also contain a substance called alkaloids, which can cheer people up and improve their self-confidence.

However, bananas are cold, and those with deficiency of spleen and stomach should use them with caution to avoid diarrhea and abdominal pain. At the same time, patients with renal insufficiency and diabetes should limit or even not eat bananas.
