The heat index value for August is evaluated at a sweltering 98.6°F (37°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
