What is the advantage of dark-skinned people and why?
It is no secret to anyone that the skin is one of the most sensitive parts of the human body, bearing in mind that it is one of the most in contact with the outside world. Poorly cared for skin can be affected by the negative effects of UV rays, such as sunlight.
However, not all shapes are alike; In fact, some are more sensitive than others to sunlight, which makes them more likely to develop skin cancer.
Thus, for example, one of the characteristics that can make a person at risk of developing skin diseases is precisely his color.
According to the American Cancer Society (ACS), “people with fair skin have a much higher chance of UV-induced skin damage (and skin cancer),” although it warns that “people with darker skin, including people of any Ethnicity, you can also be affected.”
“For some people, the skin tans when it absorbs UV rays. The cause of the tan is the increased activity and number of melanocytes, which are the cells that produce the brown pigment called melanin,” explains ASC in a blog post.
However, this pigment is not a stubborn barrier against UV rays, so at some point it can penetrate the skin in such a way as to burn it. Therefore, this organization emphasizes that “people with naturally dark skin are less likely to get sunburn, while people with fair skin are more likely to get burns.”
However, aside from skin color, there are other types of physical and even social factors that should be considered for greater sun protection, ACS details on its website.
A person should protect themselves more carefully from sunlight if:
- He had skin cancer.
- Do you have relatives who have contracted this disease? Especially skin cancer.
- Many moles are present, with an emphasis on those that are large or irregular.
- The skin is freckled, and for some reason, you get a sunburn before tanning.
- In his physique he has specific characteristics such as Fair skin, blue or green eyes, blond hair, red or light brown.
- His working conditions are indoors and on weekends he switches to a more open environment where the skin is more exposed to UV rays.
- Spends a lot of time outdoors.
- You suffer from lupus or another type of autoimmune disease.
- You are an active patient with a disease Significantly reduces the immune system, such as AIDS.
- He was the beneficiary of an organ transplant.
- If you are taking medicines that weaken your immune system or make your skin more sensitive to the sun.
Finally, the ACS states that not only the strength of UV rays can negatively affect the skin, but of course the “exposure amount” to it.
“People who live in areas where they get intense year-round sun are more likely to get skin cancer. Spending a lot of time outdoors to work or relax without protecting yourself with clothing and sunscreen increases your risk. The pattern of exposure can affect It also increases the risk of skin cancer.For example, frequent sunburns in childhood can increase the risk of some skin cancers many years or even decades later.
