The average heat index in September is evaluated at a scorching 44°C (111.2°F). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.Records show heat index calculations are tailored for shaded regions and mild winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.
