Question

1. why should you avoid intense physical activity during peak heat hours (10 a.m. to 4 p.m.)? to minimize uv exposure to your hair. to reduce the chance of sunburn. to prevent your body from overheating in extreme temperatures. to avoid dehydration entirely.

Explanation:

During peak heat hours, temperatures are high. Intense physical activity generates body - heat. Combining high external temperatures with internal heat production from exercise can cause the body to overheat. Minimizing UV exposure to hair, reducing sunburn chance, and avoiding dehydration are related but not the main reason. Dehydration cannot be avoided entirely in any case.

Answer:

To prevent your body from overheating in extreme temperatures.
