Heat index

During December, the heat index is evaluated at a very hot 35°C (95°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. Be alert! The reflection of water and sand augments UV radiation intensity.
