Men and women have different biological clocks, study shows


Male and female circadian rhythms are different in so many ways, a new study finds. The circadian rhythm is the internal process that regulates the sleep-wake cycle. While the body is regulated by many rhythms. The circadian rhythm is the most well-known of the body's rhythms. Because it affects our lives on a noticeable day-to-day basis. Circadian rhythms are 24-hour cycles that are part of the body's internal clock. They run in the background and carry out essential body functions and processes. 

When the circadian rhythm is thrown off, it means that the body's systems don't function optimally. Research also shows that circadian rhythms play an essential role in diverse aspects of physical and mental health. In addition to the circadian rhythm, humans have rhythms that control breathing the shedding of skin and the heart rate. The circadian rhythm is also involved in metabolism. It is responsible for why we get tired at certain hours as well as when we fall asleep and when we wake up. 

In the study, researchers analyzed papers on the circadian rhythm involving over 53,000 people. They found some key differences in these rhythms according to gender. They noticed that women tend to be morning people whereas men are more likely to be night people. Women also tend to be more resilient to disruptions in their sleep-wake cycle. They are more active during the day and less energetic at night. This pattern is also common in children. 

Women also tend to spend more time sleeping than men including more time in slow-wave deep sleep. On the other hand, men tend to be more alert than women while sleeping. Men also tend to take more naps in the afternoon. Researchers do not know exactly what may be the cause of these variations. They suggest that women's maternal child-bearing role may play a part. If true, it may have made more sense for women to have a circadian rhythm more in tune with their offspring.
