Heat index

The heat index value for August is evaluated at a life-threatening hot 49°C (120.2°F). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. 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.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
