Persistent activity could provoke heatstroke.Heat index details are generally centered around shaded locations and a mild breeze.

Note: The heat index, also known as 'real feel' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
