Heat index

For August, the heat index is evaluated at a sweltering 98.6°F (37°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
