Note: The heat index, also known as 'real feel' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for 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 human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
