A hat can protect you from overexposure to the sun (sunburn, skin cancer/malanoma...), from hypothermia in extreme cold. It can protect your eyes from long hair whipping into them. Those with a brim or bill can shield your eyes so that you are not blinded. A hat can keep your head from getting too rained-upon, dripping house paint from really messing up your hair or reduce the injury of bumping your head against something.
