Avoiding Sunlight
Light from the sun has both beneficial and detrimental effects on humans. The term “UV” refers to the wavelength of these radiations. UVA, UVB, and UVC are the three subsets of the ultraviolet spectrum.
UV rays can penetrate the skin even if they are invisible to the naked eye. Specifically, the epidermis is the skin’s outermost layer. The dermis is the innermost layer of skin, which is home to the body’s vascular and nervous systems. Melanin is a pigment (or dye) found in epidermal cells and is found in higher concentrations in those with darker skin tones. This explains why those with extremely pale skin tend to burn more quickly in the sun.
However, minor to significant skin, eyes, hair, and immune system damage can result from prolonged exposure to the sun’s ultraviolet rays without proper protection. It’s also been linked to cancer. Hereditary and environmental variables are also important. However, sunburn and prolonged exposure to UV rays are harmful to the skin. That’s why to avoid having minor and major UV light effects, limiting exposure to the sun is the best remedy.
