Heat index

The heat index in May is calculated to be a life-threatening hot 45°C (113°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.
Understanding the heat index involves considering values for shaded locales with light wind. 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 an amalgamation of air temperature and humidity to express the equivalent perceived temperature. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation. Take warning! Reflective sand and water surfaces intensify the Sun's UV rays.
