Heat index

In January, the average heat index is evaluated at a torrid 37°C (98.6°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Note: The maximum UV index of 6 during January leads to these instructions:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
