After swimming ashore, people usually feel cold. If the wind blows, people will even shiver. Please use it to learn
A: after people leave the water, the water on their bodies evaporates and absorbs heat, which reduces the temperature of the human body, so people will feel cold; When the wind blows, the flow rate of air accelerates, which accelerates the evaporation of water, absorbs more heat, and people will feel colder
Why does the body feel a little cold after swimming ashore
This is because when people come ashore after swimming, the water on their bodies will evaporate, and water evaporation belongs to endothermic reaction, which will absorb the heat on their skin, so people will feel cold. The evaporation process is endothermic (it means that the evaporation process itself needs to absorb heat, otherwise it cannot evaporate), and the gaseous water is better than the liquid water (equal mass)
Why do you feel cold after swimming ashore
Swimming is actually a very physical exercise. When you swim, you actually sweat a lot, that is, your sweat holes are wide open. When you get out of the water, your body is wet, and you will accelerAfter swimming ashore  people usually feel coldate evaporation when you walk. Why do you feel coldWhy do you feel heavy after swimming ashore
The buoyancy of the water is large. If you suddenly land in the water for a long time, you will not adapt to it for a period of time, and you will be unstable. You will feel a little dizzy for a while! It is suggested that the swimming time should not be too longA person will feel very cold after swimming ashore. A gust of wind will feel colAfter swimming ashore  people usually feel coldder. What is the physical reason
A: after people leave the water, the water on their bodies evaporates and absorbs heat, which reduces the temperature of the human body, so people will feel cold; When the wind blows, the flow rate of air accelerates, which accelerates the evaporation of water, absorbs more heat, and people will feel colder
Why do you feel tired and heavy after swimming ashore
Due to the buoyancy of the water in the outer water, the body will gradually like that environment. After landing, the buoyancy of the water disappears, and the missing force needs to be provided by you. Therefore, it will feel more difficult than other times, which is also similar to the reason that astronauts need to use cars to push when returning to earthWhy do you feel so heavy after swimming ashore for a long time
When people are in the water, they have buoyancy, but when they come out, they have no buoyancy, so they feel very heavy. Because swimming will sweat a lot, consume a lot of physical energy, and the body will dehydrate and feel tired after a long time; And the buoyancy in the water makes people feel relaxed when swimming, so they will feel very heavy when they get ashore. Lack of exerciseWhy do you feel heavy after swimming ashore for a long time? Urgent need
Lack of exercise. Swimming is a whole-body exercise. It also takes more energy to swim in the water. When you are in the water, you don't feel tired because the water has buoyancy and you can't feel your weight. When you swim well, you will feel tired without the buoyancy of the water. Swimming is a strenuous sportThe temperature is not high. Why do swimmers feel cold when they get ashore
The condition of evaporation is: heat absorption is required. Therefore, if our water wants to evaporate, we need to absorb our heat, so it is normal for us to feel cold when we go ashore after swimming. If there is a wind, we will dAfter swimming ashore  people usually feel coldecide to be colder; Because the wind will make the liquid flow, which will speed up the evaporation rateAfter swimming ashore in the swimming pool, people are used to putting on a bath towel so that they won't feel too cold. Why
The water on the ashore water will evaporate, and when it evaporates, it will absorb the heat energy from people. Put on a bath towel and absorbAfter swimming ashore  people usually feel cold the water, so it won't be too cold
