Heat index

April's average heat index is estimated at a torrid 35°C (95°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.
Research indicates the heat index considers values in shaded locales and with light winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
