Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
