Heat index

During December, the heat index is appraised at a burning hot 45°C (113°F). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.
Observations indicate that the heat index values are for shady locations with light wind. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
