Understand the risks and benefits of sun exposure
When talking about the risks and benefits of sunlight for human health, one of the most important things is to analyze the two factors so that you can maximize the benefits and minimize the risks in a safe and minimizing way to use sunscreens.
If what dermatologists say about the use of sunscreen to avoid melanoma is true, then melanoma should decrease as more people use sunscreens. But in fact over the past 30 years, along with the increase in sunscreen users, the number of people affected by melanoma has also increased.
Besides being able to block the activation of vitamin D, many sunscreen products contain toxic substances, which is certainly the last thing you want to have in your healthy body. Furthermore, a variety of sunscreen products also contain vitamin A and its derivatives (retinol and retinil palmitate) and various other harmful ingredients, such as oxybenzone, which are proven to accelerate the development and spread of malignant skin cancer cells.
Another important factor that you need to remember also, the SPF contained in most sunscreen products can only protect the skin from UVB rays, an ultraviolet spectrum that allows your body to produce vitamin D. Even though the spectrum of sunlight is harmful to the skin in this case causing damage and skin cancer is UVA light. So, if you still want to use sunscreen, you should first make sure that the product you buy can protect your skin from UVA and UVB.
The most reasonable and wiser way to protect the body from sun exposure is to cover the exposed part of the body with a thin cloth if you are only going to be out for a while. You can also wear a wide hat when you are outdoors for a long period of time.
