Heat index

For April, the heat index is calculated to be a blisteringly hot 43°C (109.4°F). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.
Realize that the values for the heat index are set for shaded places and light winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
