Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.
