Heat index

Throughout September, the heat index is calculated to be a fiery hot 36°C (96.8°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage. Caution! The reflection of sand and water significantly amplifies the Sun's UV radiation.
