Detailed answer

One common mistake people make when trying to prevent sunburn is not applying enough sunscreen. To adequately protect your skin, you should apply at least one ounce (about a shot glass full) of sunscreen to cover your entire body. Additionally, many people forget to reapply sunscreen throughout the day, which reduces its effectiveness. Reapplication should occur every two hours or more frequently if sweating or swimming. Another mistake is underestimating the sun's strength. Even on cloudy days or during cooler seasons, the sun's rays can still cause sunburn, so it is important to protect your skin by wearing protective clothing, seeking shade, and using sunscreen regularly.
