Heat index

January's average heat index is evaluated at a torrid 37°C (98.6°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
