Heat index

During May, the heat index is estimated at a scorching 40°C (104°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
