Which ethnic group is generally more sensitive to UV exposure?

The ethnic group that is generally more sensitive to UV exposure is Caucasian. This sensitivity is largely attributed to the lower levels of melanin present in lighter skin tones. Melanin acts as a natural sunscreen by absorbing and dissipating UV radiation; therefore, individuals with less melanin (such as those of Caucasian descent) tend to be more susceptible to sunburn, skin damage, and increased risk of skin cancer when exposed to UV rays.

In contrast, ethnic groups with higher levels of melanin, such as African Caribbean or Asian populations, typically have greater protection from UV radiation, which helps to lower their risk of related skin conditions. Native Americans display a range of skin tones, but many also have higher melanin levels than Caucasians, offering additional protection against UV damage.
