Heat index

In May, the heat index is estimated at a very hot 37°C (98.6°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
In the scope of the heat index, its values resonate with shade and light wind conditions. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. 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 primarily vital for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
