Note: The heat index, also known as 'felt air temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, 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 hold great significance to children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
