Note: The heat index, also known as 'feels like' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
