Note: The heat index, also known as 'real feel' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 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.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
