Detailed answer

Rainy days do not guarantee protection from the harmful effects of UV rays. Clouds can still allow a significant amount of UV radiation to penetrate through and reach your skin. Additionally, some UV rays can also reflect off surfaces such as water or wet pavement, further increasing your exposure. Therefore, to maintain proper sun protection, it is advisable to wear sunscreen even on rainy days. Choose a broad-spectrum sunscreen with a high SPF and apply it generously to all exposed skin areas. Remember to reapply every two hours, especially if you get wet or sweat excessively. It is also worth noting that wearing sunscreen is crucial to prevent long-term damage like premature aging, skin cancer, and sunburn, regardless of the weather conditions.
