What is a significant factor in determining the risk of sunburn for an athlete?

The significant factor in determining the risk of sunburn for an athlete is skin thickness and texture. The skin acts as a barrier against UV radiation from the sun, and individuals with thinner skin or less melanin (the pigment that provides some protection against UV rays) are generally at a higher risk for sunburn. Thinner skin can lead to less natural protection, making it easier for UV rays to penetrate and cause damage.

While hair color might seem relevant because lighter hair often correlates with lighter skin (which is more prone to sunburn), it is not a direct factor. Height and weight do not influence an individual's susceptibility to UV radiation and sunburn risk as directly as skin characteristics do. Footwear choice is entirely unrelated to sun exposure and plays no role in the risk of sunburn. Understanding how skin characteristics impact sunburn risk can help athletes take necessary precautions, such as applying sunscreen and wearing protective clothing.
