Circadian rhythms, otherwise known as the 24-hour sleep / wake cycle, determine when you feel sleepy and when it's time to wake up in the morning. In addition to your sleep, your circadian rhythm can have a huge impact on your health. According to a new study by researchers at the University of Bristol, the risk of breast cancer decreases for women who get up early compared to their nightmare counterparts. While the study not yet published expects a peer review, the findings say that one in 100 women who said they were morning men developed breast cancer, while two out of every 100 women who went to CNN.
CNN reports that for this study, sleep preferences were reported by more than 180 women of European origin in the UK. Cancer risks associated with sleep programs have been suggested by previous research, and British researchers have set out to expand on these findings with the current study. While study participants who reported themselves as early births showed lower rates of breast cancer, the reasons for this are not yet completely clear, according to the BBC. The authors of the lead study, Dr. Rebecca Richmond, a researcher at the Cancer Research UK Integrative Cancer Epidemiology Program at the University of Bristol, presented these findings at the NCRI Cancer Conference in Glasgow on Tuesday, according to CNN.
On the BBC, everyone has a body clock that influences when you sleep, your mood and perhaps even your susceptibility to certain diseases. People in the morning tend to have peak energy early in the day and get tired earlier in the evening. People who prefer to go to bed tend to be the most productive later in the evening and feel lonely in the morning than those who get up early. When circadian rhythms interrupt, mood and health disorders may result. British researchers also carried out a genetic analysis of study participants to better understand the link between sleep patterns and breast cancer risk, according to CNN.
"We know that sleep is generally important for health," Richmond told CNN. These findings have potential policy implications to influence the general population's sleep habits in order to improve health and reduce the risk of breast cancer among women.
However, while there is a link between the risk of breast cancer and sleep patterns, the statistical model used in this study does not necessarily imply causality, said Dipender Gill, clinical researcher at the Imperial College in London. For example, genetic determinants of sleep can affect other … mechanisms that affect the risk of breast cancer independent of sleep patterns, "said Gill. So while it might be sleep patterns associated at risk of breast cancer, they do not necessarily cause it, according to Gill – there may be other genetic and health factors in play.
Sleep is likely to be a major risk factor for breast cancer, Richmond told CNN. But other health factors, such as excessive alcohol consumption, are more preoccupied, she said. She also said night owls should not worry too much about the results of the study because there are many factors, some of which are genetic, which contribute to the risk of breast cancer.
When it comes to having enough sleep and reducing the risk of illnesses such as breast cancer, sleep early when you can help. And while you sleep disruptionor if you do not get enough solid sleep on a regular basis, you may increase your chances for health problems, such as some cancers, more research is needed to fully understand how circadian rhythm influences the risk of breast cancer.
