Heat index

May's heat index is evaluated at a scorching 40°C (104°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. 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. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
