If you do strenuous exercise in summer, I suggest you wear long-sleeved sportswear, because ultraviolet rays in summer are particularly harmful to your skin. If you wear short-sleeved sportswear, you will be exposed to the sun, and wearing short sleeves will do great harm to your skin, especially for girls. I think it will be hot when running, but if you sweat profusely and wear short-sleeved sportswear, it will be difficult for your skin to calm down.
Of course, I think wearing short-sleeved sportswear or long-sleeved sportswear in summer requires a lot of physical fitness. If boys wear short-sleeved sportswear in summer, it's okay to run around the playground for more than a dozen laps, because they are masculine and strong. Sweating will only have the effects of metabolism, detoxification and beauty, but for girls, it is weak or weak. After strenuous exercise, the body will be seriously short of water. At this time, you evaporate all the water vapor you sweat in the sun, which is very harmful to your body, and you are prone to heatstroke and illness.
Of course, I think about this problem from the perspective of a non-professional, but usually, people wear short sleeves when they go to strenuous exercise in such a hot summer, because it is too hot, it is difficult for anyone to stand running with long sleeves, which will reduce the harm to their health, but it is also because of severe sweating that wearing long sleeves is difficult to ventilate, which is harmful to some physical things such as eczema or small red rash.
Because this kind of thing happened before, I wore long sleeves that morning because I was afraid of the cold, but when I went to physical education class, I was a little hot at noon because I had to run, and I sweated violently. At that time, everyone else wore short sleeves and I wore long sleeves. When I came back, I found that I had a lot of small red rashes at night, which was particularly itchy. Then I bought a lot of medicine and got up.
So I said that wearing long sleeves and short sleeves has something to do with your physique. Some people don't respond at all, just a little hot, sweat a little, and then pass, but for some people, they will suffer from other troublesome diseases, so I suggest that this matter should be decided according to their personal physique. Other people's suggestions are only decided in normal weather, so just follow the normal development.
Like those more formal sports teams, I think everyone should wear short sleeves for running, so I think it is better to wear short sleeves in summer. After all, not everyone's physique can withstand long-sleeved running and produce violent reactions.
Girls can still wear short sleeves if they can't stand it, but because I'm afraid of the cold, I always wear long sleeves when running in summer weather like this. It's almost autumn.
