Heat index

In March, the average heat index is appraised at an extremely hot 40°C (104°F). Emphasize additional safety, risk of heat cramps and heat exhaustion is high. Continuous activity might result in heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
