The heat index in April is estimated at a burning hot 52°C (125.6°F). Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
