Stay hydrated by drinking plenty of water, avoid strenuous activity during the hottest part of the day, and wear light-colored, loose-fitting clothing. If you start to feel dizzy, nauseous, or weak, seek medical attention immediately.

    In the winter, hypothermia is a risk if you're exposed to cold temperatures for an extended period of time. Dress in layers, stay dry, and seek shelter if you start to feel cold or shivering. If you're planning on doing any outdoor activities in the winter, let someone know your plans and carry a cell phone in case of emergency.
