Heat index

Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. 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 especially vital to 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 is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
