In contrast to children, who must always be shielded from the sun, most people can tolerate up to an hour of sun exposure without any burns. Direct exposure to the Sun during its peak hours around mid-day should be minimized for safety. Experience reduced UV exposure by about half when donning a wide-brim hat. Take to heart! Snow reflection can almost magnify the Sun's UV radiation twofold.
