Heat index

The heat index value during June is estimated at a life-threatening hot 45°C (113°F). Notice: Heat cramps and heat exhaustion are likely. Continued strenuous activity might lead to heatstroke.
Consider that heat index readings are for situations in the shade and light wind. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
