Heat index

During January, the heat index is computed to be a fiery hot 37°C (98.6°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Realize that the values for the heat index are set for shaded places and light winds. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
