Note: The heat index, also known as 'feels like' or 'real feel', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
