Note: The heat index, also known as 'real feel' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. 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. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
