Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
