The average heat index in July is evaluated at an extremely hot 104°F (40°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
