Heat index

During April, the heat index is evaluated at an extremely hot 40°C (104°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
