Note: The heat index, also known as 'feels like' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
