Heat index

In October, the average heat index is calculated to be an extremely hot 40°C (104°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
Understanding the heat index involves considering values for shaded locales with light wind. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. 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.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Put into action all crucial precautions. Defense against sun damage is a must. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat. Sunscreen with a sun protection factor of no less than 30 should be used liberally and reapplied frequently on overcast days, including after every swim or outdoor activity. Caution! The reflection of sand and water significantly amplifies the Sun's UV radiation.
