Heatstroke might occur with long-duration activity.For clarity, heat index numbers account for light winds and areas under shade. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital 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.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
