Heat index

The heat index value for May is estimated at a blisteringly hot 43°C (109.4°F). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
