Throughout December, the heat index is estimated at a very hot 35°C (95°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. 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 largely significant 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 human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Remember, devices such as parasols or canopies might not provide complete sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
