The most suitable temperature for exercise
20-25 degrees is the most comfortable temperature for human body and the most suitable temperature for training. As the temperature rises, our bodies will gradually start to feel hot and irritable. Even if we lie down and do nothing, our bodies will be heated by metabolic activities, such as food digestion and heartbeat. So when the outside temperature is close to the body temperature, the body will start to sweat. In this way, the body temperature can be kept at about 37 degrees Celsius to ensure good health.
The more you sweat, the better you lose weight?
I wonder if there are such friends around me. They especially like summer sports. The reason is sweating at high temperature in summer, which they think is the most effective way to lose weight. This misunderstanding is mainly due to being misled by various weight loss advertisements all the year round, thinking that fat will turn into sweat and be excreted.
In fact, fat, as the most abundant energy supply substance in our body, is usually used as a very low-intensity or long-term low-intensity energy supply for our daily body, and it is one of the functional raw materials for aerobic oxidation. Although the oxidation process of fat will produce water, sweating in hot environment has little to do with the oxidation of fat.
Sweating is a way for human body to regulate body temperature, with only one purpose: heat dissipation. Just like the water tank of a car, if there is no water tank, the engine will overheat and be damaged. When we eat spicy hot pot, we will sweat because it is spicy, but we won't lose weight after eating it, just because our body is sweating and cooling down, because it thinks you are burned.
So sweating does not mean burning fat. When we exercise, our bodies produce a lot of heat, which makes our body temperature rise rapidly. If sweating does not help the body temperature drop, but continues to rise, then be careful of heatstroke. For our daily life, turning on the air conditioner to cool down is one of the good ways to effectively avoid heatstroke and maintain the level of exercise. It is often seen that some friends are unwilling to use air conditioning for training even in a very hot environment because they are afraid of catching a cold. In fact, turning on the air conditioner is not the main reason for catching a cold. More importantly, it is very important to control the temperature at a temperature suitable for exercise.
Keep the relative humidity, and exercise will be very comfortable.
The humidity in the south has reached 90% recently. I feel wet and sticky when I sweat every day, especially when I exercise. Relative humidity is another physical index that we need to strictly control, and 40%-60% relative humidity is most suitable for our exercise.
If the relative humidity is too high, the endocrine system of human body will not work normally, which will lead to low mental state and affect physical condition and sports performance. When the humidity increases, the evaporation of water in the body will slow down, and the heat generated by the body cannot be taken away in time, resulting in an increase in body temperature.
On the contrary, if the humidity is too low, the air will become dry, and the water in the body will easily lose quickly, which will also affect sports performance and even endanger health. Therefore, it is very necessary to maintain a relatively suitable humidity. In indoor ventilation environment, open windows or electric fans to increase air flow, take away moisture and bacteria, or use air humidity control equipment to improve environmental humidity.
