Heat index

Throughout August, the heat index is computed to be a life-threatening hot 113°F (45°C). Warning: Heat cramps and heat exhaustion are anticipated. Heatstroke is a risk with ongoing activity.
In reference to the heat index, it's for places in shade and with a slight wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
