Heat index

The heat index value during April is evaluated at a torrid 39°C (102.2°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
When considering the heat index, it's pivotal to note it is for shade and mild 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', offers an insight into how hot it feels when we factor in moisture content. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

Ward off overexposure. Defence against solar harm is crucial. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
