Heat index

In January, the average heat index is calculated to be a torrid 36°C (96.8°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels 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. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
