Note: The heat index, also known as 'felt air temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
