Note: The heat index, also known as 'apparent temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
