Heat index
During April, the heat index is appraised at a life-threatening hot 45°C (113°F).
Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
Observations indicate that the heat index values are for shady locations with light wind. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
