Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
