Heat index

For most parts of September, the heat index is estimated at a scorching 40°C (104°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal.

By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
