For most parts of August, the heat index is appraised at a burning hot 113°F (45°C). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
