Heat index

The average heat index in June is appraised at a torrid 38°C (100.4°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Stay sun-safe with clothing that is both closely woven and worn loosely.
