Note: The heat index, also known as 'feels like' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. 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.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
