Why do red spots appear on your arms when your body gets hot?

It may be because the skin is relatively sensitive. Once the body heats up and sweats, the skin on the arms will become allergic and produce red spots.

Don’t think this is alarmist. I had a classmate who went to college in Guangzhou. He told me that when the weather in Guangzhou was very hot, he would sweat every day, and the most terrifying thing was that he would sweat every day. As soon as you sweat, a rash will appear all over your body.

We must know that people in the north rarely have allergic reactions all over the body and face, because every summer, on the one hand, there is air conditioning in the house, and on the other hand, the humidity of the entire environment is relatively low. Low, it is difficult to have the feeling of being wet, sticky, and sweating all the time.

But it is different in the south. The environment in the south is relatively hot and humid. The humid environment makes people always feel sticky, as if there is always a layer of water hanging on the skin. In this environment , if you sweat, your skin will immediately secrete a lot of sweat, that is, salt. These salts will always adhere to your skin, which will cause your skin to have an allergic reaction.

Sometimes even if the amount of sweating is not very large, if the skin is relatively fragile, some rashes will appear immediately. This is why some children with delicate skin will develop allergic rashes in summer.

If you really get a rash for this reason, in this case, you must try your best to ensure that you can take a shower regularly. After taking a shower, not only do you not allow the skin to dry naturally, but you also need to Apply as much clean moisturizer as possible, be sure to use a mild moisturizer that can eliminate allergies. In this case, slowly adjust the balance of the skin, and at the same time reduce the irritation of the salt on the skin, and see if it can help you The current situation has improved.
