Heat index

The heat index for April is estimated at a burning hot 49°C (120.2°F). Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
