Detailed answer

To prevent hyperpigmentation during outdoor sports, it is crucial to take necessary precautions. Firstly, apply a broad-spectrum sunscreen with a high SPF (30 or above) to protect your skin from harmful UV rays. Reapply every two hours, especially if you perspire heavily. Additionally, cover exposed areas with protective clothing such as hats, long-sleeved shirts, and pants to minimize direct sun exposure. Seek shade whenever possible, especially during the peak hours of 10 am to 4 pm when the sun's rays are strongest. Remember, consistent sun protection measures are key to avoiding hyperpigmentation and maintaining healthy skin.
