Heat index

Take into consideration that the heat index values are calculated for shade and light wind conditions. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
