Why should you avoid sun exposure between 10:00 a.m. and 4:00 p.m?

• A. UV rays are most intense during this time.
• B. The sun is at its strongest at night
• C. Clouds block all UV then
• D. Sunscreen is not effective then

Answer: (A)

Midday sun has the strongest UV radiation because the sun is highest in the sky, sending rays more directly toward the earth. This direct angle means more UV reaches your skin in a shorter time, increasing the risk of sunburn and long-term skin damage. Clouds don’t block all UV, so exposure can still be significant on overcast days. Sunscreen helps reduce UV absorption but isn’t a perfect shield and needs to be reapplied, especially after sweating or swimming. So, avoiding or limiting sun exposure during these peak hours is the most effective way to lower UV damage.
