Heat index

Throughout September, the heat index is evaluated at a life-threatening hot 47°C (116.6°F). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
