Note: The heat index, also known as 'real feel' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. 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. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
