Note: The heat index, also known as 'real feel' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital 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. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
