Sunburns are the most common effect of long-term sun exposure. However, just because you do not get a sunburn does not mean damage was not done to the health of your skin. Along with cosmetic and aesthetic changes to your skin, the ultraviolet rays from the sun can cause unhealthy and, in severe cases, harmful effects.
When outdoors, physically blocking the sun’s rays is the best defense. Whether a wide-brimmed hat or long sleeves, covering your skin with opaque material will prevent the UV rays from reaching your skin. It is also important to remember that UV rays can reflect off other surfaces like the ground and do not solely come from where the sun is positioned.
While this is helpful in cooler temperatures, it becomes uncomfortable as the temperatures continue to rise. When you cannot wear longer garments or a wider hat, sunscreen with a high sun protection factor (SPF) will help block UV rays.
In general, the higher the SPF of the sunscreen, the more effective it is at blocking both UVA and UVB rays. However, once above SPF 30, the increase in effectiveness slightly slows. SPF 30 sunscreen blocks about 97% of UVA and UVB radiation, while SPF 50 is effective against 98%.
It is also important to remember to reapply sunscreen often during longer outdoor activities. This is especially true with periods with a lot of sweat or exposure to water.
