Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
