The Circadian rhythm, otherwise known as the body's 24-hour sleep / boost cycle, determines when you feel drowsy and when it's time to wake up in the morning. However, despite your sleep, your daily rhythm may affect your health. According to a new study by the University of Bristol, the risk of breast cancer decreases for women who wake up early, compared to their night owl colleagues. Although the pending study still puts a peer review, findings suggest that one in every 100 women who said they were morning people developed breast cancer, but two out of every hundred women who described themselves as later patients developed the disease, according to with to CNN.
CNN reports that in the UK, more than 180 European women in the study reported sleep choices. Previous studies have shown the risk of cancer associated with sleep patterns, and UK researchers have decided to extend these findings to the current study. According to the BBC, study participants who reported themselves early in the year showed a lower incidence of breast cancer, the reasons for which remain unclear. According to CNN, on Tuesday, a study by Dr. Bristol University in the University of New York at the Cancer Conference in Glasgow. Rebecca Richmond, researcher at the University of Brighton Cancer Research UK Integrated Cancer Epidemiology Program.
For example, on the BBC, everyone has a body clock that affects sleep, your mood, and even your susceptibility to certain diseases. Morning people usually have an energy peak earlier in the day and get tired earlier in the evening. People who would like to sleep later are usually the most productive later in the evening and feel sleepy in the morning than the early ones. When the daily rhythm is disturbed, mood and health problems may occur. British researchers also conducted a genetic analysis of participants in the study to better understand the relationship between sleep patterns and breast cancer, according to CNN.
"We know that sleeping is generally important for health," Richmond told CNN. "These findings have a potential impact on policies affecting people's sleep habits to improve health and reduce the risk of breast cancer for women."
However, although there is a link between breast cancer risk and sleep patterns, the statistical model used in this study does not always point to a causal relationship, says CNP clinical research assistant at Imperial College in London, Dipender Gill. "For example, genetic sleep factors can also affect other … mechanisms that affect the risk of breast cancer regardless of sleep patterns," Gills said. So while sleeping patterns might be connected With the risk of breast cancer, it does not necessarily lead to it, according to Gill – there may be other genetic and health factors in the game.
"Sleep is probably an important risk factor for breast cancer," Richmond told CNN. But other health factors, such as excessive alcohol consumption, raise concerns, she said. She also claimed that night owls should not be too worried about the results of the study, as many factors, some of which are genetic, contribute to the risk of breast cancer.
When it comes to enough sleep and in order to reduce the risk of diseases such as breast cancer, sleep earlier when you might be helpful. And while sleeping disturbances, or regular lack of sleepiness, may increase your chances of health problems, such as some cancers, more research is needed to fully understand how day-to-day rhythm affects the risk of breast cancer.
