Heat index

Throughout May, the heat index is appraised at a life-threatening hot 50°C (122°F). Take caution: Heat exhaustion and heat cramps are probable. Heatstroke may be imminent with ongoing effort.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.

Always prioritize safety measures. Rapid harm can befall unprotected skin and eyes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
