Heat index

February's average heat index is computed to be a sweltering 35°C (95°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
