Heat index

The heat index value for April is evaluated at a blistering 40°C (104°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
