Even during the rainy season in the tropics, ultraviolet (UV) radiation remains a serious issue. Although clouds can block direct sunlight, invisible UV rays, specifically UVA and UVB, can still penetrate through them and harm your skin. In fact, research shows that clouds can sometimes reflect UV radiation, increasing its intensity and the risk of sun damage.
This is why using sunscreen is crucial. Sunscreens act as protective barriers against the sun and UV rays. Ingredients like zinc oxide and titanium dioxide prevent UV rays from penetrating the skin. Other substances, such as oxybenzone and octinoxate, absorb the UV rays and convert them into heat, which is then released from the body as sweat. By using sunscreen, you can effectively protect your skin from the harmful effects of UV radiation, even on cloudy days.
