Persistent activity may lead to heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
