Heat index

January's average heat index is appraised at a life-threatening hot 47°C (116.6°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.
Note that heat index values are valued for light wind and location in the shade. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
