In September, the average heat index is appraised at a blisteringly hot 43°C (109.4°F). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.Consider that heat index readings are for situations in the shade and light wind. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold great significance to children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
