Doctors Say These Heat Exhaustion Symptoms Should Never Be Overlooked

Although heat-related deaths are easily preventable, about 618 deaths are caused due to extreme heat every year in the US. This data is provided by the national public health institute of the US, the Center of Disease Control and Prevention. For the most part, heat-related diseases are caused when the body isn’t able to cool off properly. Normally, sweat cools off the body adequately. But, that is not enough for cases of extreme heat.

While in the middle of a heat stroke, your body will be unable to regulate its temperature. According to the Center of Disease Control and Prevention, during a heat stroke, the body temperature can rise to as high as 106 degrees in under 10 minutes. Consequently, if it is not treated immediately, this illness can cause permanent disability or even death.
