Heat index

The heat index for September is calculated to be a torrid 38°C. Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are quite important for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
