Have you had more headaches during the summer months? Are you exhausted after being in the heat for a short time? There is more than just heat at play!
During the summer months, most people crank the A/C and stay indoors. This does a few things... one: works your A/C harder, and increasing the chance of a mechanical failure. It also increases your electric bill.
Two, it causes you to be more sensitive to extreme temperatures. Walking from a 70 degree home or car into 107 degree summer means your body is on overdrive trying to keep your body cool, increasing your chances of hyperthermia. Once warm, going back into that cool room could result in hypothermia. A sweaty hot body can cool below 95 degrees in a small amount of time.
Moderate your exposure. Raise the A/C a few degrees, and make sure you are drinking water and eating healthy food. The most important thermostat is the one in your body, so take care of it! Try to keep those temperatures inside of a 20 degree range!
