How sunbathing can prevent skin cancer

How does sunbathing prevent skin cancer? In fact, sunbathing can increase the risk of skin cancer. Skin cancer is caused by exposure to the sun. Isn't it said that frequent sunbathing can promote calcium absorption? But now many examples show that people suffer from skin cancer and are closely related to frequent sunbathing, especially in summer. We must do a good job of sun protection. Let's take a look at the relationship between the two.

First, be alert to skin cancer if you are often exposed to the sun in the summer

At present, there is a lot of evidence that frequent exposure to ultraviolet radiation, the interaction between the protection of human melanin and the immune system function are closely related to the occurrence of skin cancer. When measuring human skin in sunlight, the parts of the skin that receive the most ultraviolet rays are the head, face, back of the neck, and hands, and squamous cell carcinoma almost all occur in these parts. If a person has been sunburned many times in his life, then the degree of sunburn over many times and many years will accumulate, causing skin damage and many skin diseases, such as solar keratosis. Therefore, people with a genetic background for skin diseases should avoid light and sun protection in the summer, because such people are much more likely to suffer from solar skin cancer than those without a genetic background, such as basal cell carcinoma, squamous cell carcinoma, malignant melanoma, etc.

In the hot summer, frequent exposure to strong sunlight can not only cause heatstroke, but also cause sunburn and lead to skin diseases. Therefore, experts remind that you need to pay attention to the time period and duration of sunbathing. Sunburn refers to a phototoxic reaction caused by a large amount of exposure to ultraviolet rays in a short period of time. In mild cases, the local skin exposed to the sun becomes red and swollen, and in severe cases, blisters appear. The more times of cumulative sunburn, the more serious the damage. Under normal circumstances, human cells will repair themselves after being damaged. If there is no natural repair or the natural repair ability is not strong, if human cells mutate, it is possible to develop skin cancer, which is especially likely to occur in the elderly. People with hereditary skin diseases are more likely to get skin cancer after repeated sunburns.

Second, we must prevent skin cancer and sunburn in time.

In order to prevent skin cancer fundamentally, the most important thing is to prevent sunburn. In the hot summer, try to avoid the time when the sun is directly overhead, take protective measures when going out, such as holding an umbrella or wearing a wide-brimmed hat, long-sleeved clothes, wearing dark clothes or applying sunscreen when going out, and reduce the time spent in the sun.

After the experts' introduction, you believe that there is a great relationship between improper sun exposure and skin cancer. Since the experts have introduced this, we must do a good job of sun protection, especially in the summer when children are very naughty and their skin is very tender, which is more vulnerable to damage. Everyone must be more vigilant about skin cancer.
