Those spending time outdoors to celebrate the 4th of July holiday should take proper precautions to being outside in the sun. The Indianola Fire Department says if you are planning on being outside for an extended amount of time to drink plenty of water, and to watch for signs of being overheated such as extreme fatigue, nausea, or a headache, and if you need to take a break in the shade or air-conditioning to do so. If there are any questions if someone is dealing with a heat-related illness, do not hesitate to call 911.
