Note: The heat index, also known as 'felt air temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. 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 particularly relevant to babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
