Continuous activity might result in heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
