London, 6 November. / Tass /. The risk of cancer can be related to human chronotypes, referring to UK researchers. According to The Times, the authors of the study on Tuesday in the country found that women who considered themselves "larke" were breast cancer cases 40 percent less often than women "owls".
Increased oncological risks were observed not only in the owl but also in the study population who slept more than the recommended seven to eight hours per day. Each additional sleeping speed increased the likelihood of developing the disease by approximately 20%. According to research director Rebecca Richmond, the University of Bristol is still unclear whether this image is affecting changing lifestyle and sleep disorders.
The results of Richmond and his colleague were made after discussing the large-scale statistical database of UK Biobank involving more than half a million volunteers and the international genetic research conducted by the Breast Cancer Society. In summary, the information provided to 409,000 women by researchers. The results of the researchers have not yet been published in scientific journals but were presented to Glasgow's National Congress on Cancer Research on Tuesday.
"Perhaps there is a general pertinent reason that a person is" irritating "and that he has risk factors for developing breast cancer," said Dipender Gill, a London Imperial College employee who did not participate in the study. affect the neuronal mechanisms that affect the risk of developing breast cancer regardless of what kind of dream person he or she is following. In this case sleeping problems are associated with cancer risk but are not their immediate cause oh. "
Earlier studies in different countries indicate a relationship between increased risk of cancer and night work. One explanation might be that people working in the night shift do not get enough sunlight, which is essential for the development of breast cancer to produce a hormone-producing melatonin. The World Health Organization includes night shift on the list of likely carcinogens.
