Persistent activity may provoke heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
