Generally speaking, in the case of sweating more, especially when engaged in strenuous exercise in summer, you should drink some light salt water appropriately. In summer, when the temperature is high and the humidity is high, the human body will emit a lot of heat energy in time through perspiration to keep the body temperature relatively stable. When the body sweats a lot, it will take away a lot of inorganic salts, such as sodium, potassium and magnesium. According to measurement, running a marathon takes away 30 grams of sodium chloride with sweat. However, a person's daily intake of sodium chloride from food is only 10 ~ 15g, which will inevitably lead to salt deficiency in the body, fatigue and weakness, and even muscle spasms or cramps. Therefore, it is necessary to drink some light salt water when engaging in strenuous exercise in summer.
Exercise under the conditions of not too much intensity, not too long time and not too high ambient temperature will generate less heat in the body and will not produce a lot of perspiration and inorganic salt loss. Neither salt water nor sugar water is needed at this time.
If it is a long-term exercise, such as running a marathon, long-distance running by bike, etc. And your body consumes a lot of energy, so you should drink some sugar water or sugar salt water properly. As for general physical exercise, there is no need to drink sugar water.
As for food, tofu, dried tofu and all kinds of bean products, as well as fresh fruits, melons and fruits and all kinds of vegetables are most suitable for eating after work and exercise. These are all good alkaline foods. Kelp is called "the crown of alkaline food". In addition, stir-fry sesame seeds and soybeans, add ginger and a little salt, and brew with boiling water to quench your thirst. Sesame, soybean and ginger are all good alkaline foods, which are also very beneficial to reduce the acidity in the blood and eliminate post-meal fatigue.
