Note: The heat index, also known as 'apparent temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
