Heat index

The heat index value during April is evaluated at a burning hot 52°C (125.6°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.
When referencing the heat index, its values are suitable for shady environments and light breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Without constant care, eyes and skin might suffer damage in a short time. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
