Heat index

The average heat index in January is calculated to be a blazing hot 47°C (116.6°F). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.
Note that heat index values are valued for light wind and location in the shade. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Resist overexposure. Safeguarding from solar damage is indispensable. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
