Heat index

During September, the heat index is appraised at a blisteringly hot 44°C (111.2°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial.

Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
