The Dog Days Of Summer are upon us. If you are from New Orleans, you know these conditions will stick with us at least till the end of August, but most likely till September. The heat will put some stress on your body. So what exactly happens to you when you are outside in the heat?
Your Body’s Defense Mechanisms
When it is very hot outside we sweat, feel dizzy and sometimes get headaches. When it is hot, the tiny blood vessels near the surface of your skin (capillaries) dilate, which increases the blood flow. This is your body’s attempt to radiate heat. High temperatures coupled with high humidity cause more blood flow to the skin, which may require the heart to beat faster and harder. Furthermore, heat and sweating lower the amount of fluid in the body, which can reduce blood volume and lead to dehydration. The combination of increased blood flow to the skin and dehydration may drop your blood pressure.
What You Should Do
Avoid strenuous activities outside, especially during the day. Drink lots of water. People should have 8 -10 glasses of fluid every day, according to experts. Keep in mind, cold water will help your blood vessels t constrict, so running some cold water over your forearms may help and make you feel better. When going inside, use your air conditioner or fan. In general, adults should never stay in temperatures over 100°F without good air flow.
