Heat index

During June, the heat index is computed to be a torrid 36°C. Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Rising body temperatures due to excess heat retention could signify impending heat disorders.
