Heat index

Throughout April, the heat index is calculated to be a blistering 40°C (104°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
In terms of the heat index, values are set with light wind and shade conditions in mind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
