Heatstroke could follow lengthy activity.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes.

Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. 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 and potential dehydration arise when body heat gain eclipses its release capability.
