Heat index

The heat index value during May is evaluated at a blistering 40°C (104°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
