It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
