Heat index

August's heat index is appraised at a very hot 37°C (98.6°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. 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. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades. Caution! Sand and water surfaces escalate the UV intensity from the Sun.
