Heat index

For most parts of May, the heat index is computed to be a blistering 40°C. Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
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. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
