Heat index

Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
