Heat index

For most parts of May, the heat index is evaluated at a blisteringly hot 40°C (104°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. 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. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
