If you think it's only hot outside, consider what happens when it gets hot inside (your body):
- Under extreme heat conditions, the human body begins the shutdown process in less than an hour. The heart and kidneys fail as the body is unable to regulate its internal temperature.
- At 104 degrees F. heat exhaustion starts, with symptoms including muscle aches, dizziness, nausea, severe thirst, and agitation.
- At 105 degrees F. the heat stroke process begins, and the symptoms increase: convulsions, vomiting, loss of consciousness, and rapid heartbeat.
- At 107 degrees F. irreversible organ damage is underway.
