“Al-Musnad”: The body’s ability to sweat and cool down in humid cities is less than in dry cities

Weather of Arabia - Dr. Abdullah Al-Misnad, former professor of climate at Qassim University and vice president of the Saudi Weather and Climate Society, explained that the body’s ability to sweat and cool down is less in humid coastal cities compared to dry Riyadh, and therefore, the body temperature rises in residents of coastal areas who suffer from lack of or Lack of cooling through sweating, which causes feelings of fatigue, boredom, laziness, exhaustion, irritability, and lack of productivity compared to residents of dry areas.

Al-Musnad added:

"The state of comfort cannot be assessed by looking at temperature alone. Rather, temperature must be taken into account along with relative humidity as a factor influencing the efficiency of the body's cooling process, which is known as the true temperature."

He explained that if the temperature in an inland city like Riyadh was 45 degrees Celsius, and in a coastal city in the east or west of Saudi Arabia, it was 35 degrees Celsius, with relative humidity in Riyadh reaching 15% and 70% on the coast, then the body’s feeling of comfort in hot and dry Riyadh would be Much better than the hot and humid coastal cities. In Riyadh, the body senses a temperature of about 44 degrees Celsius, while in coastal cities, according to previous values, it senses a temperature of 50 degrees Celsius.
