Heat index

The heat index value during January is evaluated at a fiery hot 37°C (98.6°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. 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. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage. Stay vigilant! UV rays get a boost in intensity due to sand and water reflections.
