Heat index

May's mean heat index is appraised at a life-threatening hot 49°C (120.2°F). Be cautious: Heat exhaustion along with heat cramps are predicted. Heatstroke is a possible consequence of continuous physical effort.
When referencing the heat index, its values are suitable for shady environments and light breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
