Heat index

December's mean heat index is estimated at a scorching 43°C (109.4°F). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', arises from combining readings of air temperature and relative moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
