Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. 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 extremely significant for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
