Heat index

December's average heat index is appraised at a sweltering 37°C (98.6°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
