Return to article list ● Is sun tanning healthy? Sunburn is a defense mechanism in which our bodies try to protect themselves from damage caused by ultraviolet rays. ●If you're already tanned, is it okay to be exposed to more sunlight? While sun tanning does offer some protection against UV rays, the effect is minimal. Don't let your guard down just because your skin is dark; it's important to properly protect yourself from UV rays. ● Do you avoid sunburn on cloudy days? You can still get sunburned on cloudy days. Thin clouds can let 80% of ultraviolet rays through, and dust and dirt in the atmosphere can increase your exposure to ultraviolet rays. ● Do you not get sunburned in the water? It's not true that water completely blocks ultraviolet rays. Furthermore, reflection from the water's surface can still result in significant exposure to UV radiation. ● Are winter UV rays not dangerous? Generally, winter UV rays are not as strong as summer UV rays, but you are still exposed to them, so caution is necessary.The amount of ultraviolet radiation is almost doubled when reflected by snow, so be especially careful on high mountaintops where you are closer to the sun. ● Is it okay to be exposed to sunlight for a long time if I'm wearing sunscreen? Over time, the product will gradually wear off due to friction from clothing and sweat. We recommend reapplying it regularly. ● If you take breaks while sunbathing, will you avoid getting sunburned? Ultraviolet rays accumulate over time, so even if you take a break, the effects of UV radiation will still become apparent. ●If you don't feel the heat from the sun, will you not get sunburned? We feel heat from infrared rays, while ultraviolet rays are a major cause of sunburn and photoaging. Even on cool days, ultraviolet rays are still present, so it's important to protect yourself properly.
