Understanding Sun Damage and Ethnic Skin
As the summer season approaches, most of us think about vacations, picnics, and fun activities in the sun. But too much sun can cause sun damage to all skin types. Different ethnic skin types, such as African American, Hispanic, and Asian may be more prone to sunburns, skin cancer and other sun-induced skin problems. Knowing the right information on how to stay safe in the sun can protect you and your loved ones from potential health issues. In this article, we will discuss how different skin types respond to UV exposure, the benefits and risks associated with sunning, and the importance of preventive measures.
Understanding The Sun and UV Rays
The sun emits three types of ultraviolet (UV) rays: UVA, UVB, and UVC. UVA rays are the longest and most prevalent type, and can penetrate clouds, glass, and even the skin. These rays can cause tanning, and long-term, chronic exposure can lead to photoaging of the skin, aging spots, and skin cancer. UVB rays are shorter in wavelength, and they are the ones responsible for burning. UVC rays are the shortest type, and they have the highest energy level. Fortunately, UVC rays are mostly absorbed by the ozone layer, so they don’t reach the Earth’s surface.
Sun Damage on Different Skin Types
People with dark ethnic skin tend to have a higher number of fibers in their dermis, which provide some protection from UV radiation. But even though dark skinning has a natural tendency to protect from sun damage, sun exposure should still be limited, and protective measures should be taken. People with light skin have a much lower density of dermal fibers, so they need to apply sunscreen with an SPF of 30 or higher, and wear protective clothing when out in the sun for extended periods of time.
Benefits and Risks of Sun Exposure
Sun exposure can be beneficial when limited and balanced. Moderate levels of UV radiation have been shown to have therapeutic benefits on the skin, including improved mood, increased vitamin D production, and improved circulation. But sunburns, sunspots, melasma, and skin cancer are some of the risks associated with excessive sunning.
No matter the skin tone, Sun Protection is the best defense. The most important preventive measure is to apply sunscreen with a sun protection factor (SPF) of 30 or higher, and reapply it every 2 hours, or after swimming or sweating. The sun is at its strongest between 10am and 4pm, so try to stay in the shade during those hours. Wear protective clothing like wide-brimmed hats, long-sleeved shirts, and sunglasses, and limit sun exposure when possible.
Sun damage is a danger for all skin types, and it’s especially important for people with dark ethnic skin to take the extra steps to protect themselves from UV exposure. Knowing the right information, and following preventive measures, like applying sunscreen and wearing protective clothing, can help keep you and your loved ones safe in the sun.
