Heat index

The heat index in May is calculated to be a sweltering 39°C (102.2°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. 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 staple for defending the face, eyes, ears, and neck from the Sun.
