Note: The heat index, also known as 'feels like' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
