It is important to note that the heat index values are for shaded areas and light wind scenarios. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
