What does extreme heat do to our bodies?
As the body gets hotter, blood vessels dilate to increase blood flow to disperse the heat from the body. This leads to lower blood pressure and makes the heart work harder to push the blood around the body. The body sweat to help remove the heat too. Sweating leads to the loss of fluids and salt and ratio of fluids and salt.
One can get mild symptoms such as an itchy heat rash or swollen feet as blood vessels become leaky.
More severe symptoms from heat exhaustion include: dizziness, nausea, fainting, confusion, muscle cramps, headaches, heavy sweating, tiredness.
If blood pressure drops too far, the risk of heart attacks rises.
Why do the bodies react like this in heat wave?
Our body has temperature about 37C. Whatever the environment temperature is-- cold or hot, the body need to maintain its own temperature to survive.
If the weather gets hotter, the body has to work harder to eliminate the heat from the body and to keep its temperature down.
