This effect is subjective, depending on the activity and individual's heat perception influenced by various reasons (differences in body mass, height, and shape, metabolic differences, clothing).

On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. Beware! The reflection of water and sand dramatically increases exposure to the UV rays.
