Heat index

Throughout June, the heat index is evaluated at a blisteringly hot 43°C (109.4°F). Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.
Data suggests that the heat index is set for environments in shade and with a light wind. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
