Heat index

The heat index value for January is evaluated at a sweltering 38°C (100.4°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
