Sustained activity might cause heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial 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.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
