Note: The heat index, also known as 'real feel' or 'feels like', quantifies the warmth felt when relative humidity is considered. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
