Note: The heat index, also known as 'feels like' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
