Heat index

The heat index for January is computed to be an extremely hot 43°C (109.4°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. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
