Heat index

For September, the heat index is appraised at a blazing hot 45°C (113°F). Remain cautious: Heat cramps along with heat exhaustion are foreseeable. Ongoing activity may precipitate heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Practice every precaution of necessity, unprotected skin and eyes might burn in minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear. Frequent application of a broad-spectrum SPF 30+ sunscreen is crucial, reapply it every two hours or immediately post swimming or outdoor exercise. Heed this! UV intensity is much stronger when reflected off sand and water.
