Heat index

The heat index value during December is estimated at a torrid 35°C (95°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. 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. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
