Two specialists for “Okaz”: For this reason, astronauts sleep less and need sleeping pills – Saudi News

Two specialists in sleep medicine at King Abdulaziz University Hospital in Jeddah, Dr. Rania Al-Shamrani, consultant pediatrician, pediatric thoracic and sleep medicine researcher, and sleep medicine researcher, Dr. Murad Yesawi, explained to Okaz that medical evidence has consistently proven that intermittent sleep is a very common and important problem among astronauts. It was observed that astronauts’ sleep duration and sleep quality were negatively affected by several common factors including gravity, isolation, persistent high concentration, uncomfortable ambient temperatures, high noise levels, and uncomfortable sleeping bags.

And they continued: Several studies have found that the number of hours astronauts have is less than normal by an hour or two, and the average number of hours of sleep per day is estimated at 6 hours (the normal is 8 hours), in addition to other studies that found that their sleep quality is poor.

They pointed out that astronauts are required to maintain behavioral performance and bear stress despite chronic exposure to stress and challenges during space flights, and therefore a study was conducted published at the beginning of this year in which astronauts were monitored before (6 months), during and after (6 months), After completing the flight, it was noted that the astronauts who slept less, had their behavior affected, and that sleep periods of less than 6 hours were associated with a significant decrease in the speed of motor response, and increased stress, and sleep periods of less than 5 hours were associated with negative physical behavioral states, while periods of sleep less than 5 hours were associated with negative physical behavioral states, while periods of sleep less than 5 hours were associated with negative physical behavioral states. Longer sleep had a beneficial effect on astronauts’ behavioral functions.

They said sleep problems can impair the work performance and health of crew members, which could ultimately affect the safety of flight missions and flight crew members. NASA has listed sleep deprivation and circadian changes as risk factors during long-haul flights.

At the conclusion of their conversation, they emphasized that sleep is defined as a natural vital state in which a person is in a phase of relaxation and in which his voluntary movements and feeling around him are reduced, and good sleep is very important for maintaining physical and mental health, cognition and performance of work for the general public, and healthy sleep generally includes sufficient sleep duration and quality of sleep. good.
