Sunlight and ultraviolet radiation carry both benefits and potential health risks.

They help maintain a good mood, reduce the likelihood of diseases, and also contribute to the formation of vitamin D in the body. However, excessive exposure to UV radiation can cause skin damage and the development of skin cancer.
The optimal amount of time spent in the sun to produce vitamin D depends on many factors, including skin color and the intensity of UV radiation. For example, for people with fair skin it is enough to be in the sun for 5-10 minutes, if we are talking about summer, when the body is only wearing shorts and a T-shirt.
In winter, taking into account winter clothes, it will take almost an hour in the middle of the day (from 10:00-15:00). Experts say dark-skinned people require more time in the sun to produce vitamin D, but they are less susceptible to the harmful effects of UV radiation.
There are different levels of risk for developing skin cancer. Those at highest risk are those with a history of skin cancer, multiple moles, and immunosuppression. Medium risk is for those who have dark skin that sometimes burns. The risk is lowest in people with deeply pigmented skin.
Given these factors, it is important to find a balance between getting enough sunlight for your health and avoiding overexposure to UV radiation, which can lead to harmful effects.
Recall that it was previously reported how the human body ages: scientists named three stages.
