A UV Index reading of 2, and below, represents a low threat to health from exposure to the Sun's UV radiation for the ordinary person.Note: The maximum daily UV index of 1 in April interprets into the following recommendations:
Most individuals can handle sun exposure for up to an hour without burning, but children must always be shielded from sun exposure. The Sun's most intense and consequently most harmful UV radiation during midday hours should be decreased by minimizing exposure and seeking shade. 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. Mind this! Nearly twice the UV radiation from the Sun can be reflected by the snow.
