Heat index

The heat index in January is estimated at a blistering 41°C (105.8°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. 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. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
