Heat index

January's average heat index is estimated at a fiery hot 37°C (98.6°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Note that heat index values are valued for light wind and location in the shade. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Frequent application of a broad-spectrum SPF 30+ sunscreen is crucial, reapply it every two hours or immediately post swimming or outdoor exercise.
