Note: The heat index, also known as 'apparent temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
