Heat index

During September, the heat index is computed to be a sweltering 35°C (95°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
