Our body requires a particular temperature range in order to survive. Our body temperature should be constant at 36.6 C in order to normally maintain our bodily functions. Several body temperature regulating mechanisms are activated depending on variation at temperature of outer environment, and thus, change of body temperature is avoided. Sweating and vaporization of sweat ensures heat loss of body.
Temperature rise is one of those conditions, which leads to illness and death that come up depending on weather conditions. Heat can cause exhaustion, heat stroke, cardiovascular disease and respiratory disease. Hot weather does not pose equal effect on everyone. Patients with heart disease and other chronic disease, children and elders, athletes and those who have mental illness are more prone to consequences of hot weather.
