Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important 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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
