Heat index

The average heat index in April is appraised at a sweltering 37°C (98.6°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Consider that heat index readings are for situations in the shade and light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
