“Owls” to develop cancer of the breast 48% more likely “the lark”

Rising early in the morning the so-called “larks” on 48% less likely to face breast cancer compared with “owls.” It turns out, following the natural biological rhythms reduces the risk of development of malignant neoplasms.

Under the category of “lark” fewer women are faced with breast cancer, compared with “owls.” A study involving more than 400 000 women showed that the breast cancer risk in women from the category “owls” on 48% higher. Scientists from the University of Bristol also found that sleeping longer than the recommended 7-9 hours increase thereby the chance of installing the worst diagnosis by 20% for each additional hour of sleep. One explanation of this phenomenon may be that better functioning in the morning people have a higher level of sleep and Wake up early.

But “owls” function better in the evenings, which they often have reduced sleep quality that may increase the risk of cancer. The need a long time to go to bed at night affects natural circadian rhythms. The findings of this study confirm previous work that show that aired in the night shift people are more likely to suffer from cancer. British scientists have now analyzed the genes of more women and using a special set of issues of whether they belong to the category of “larks” or “owls”.

In the future, the researchers would like to study the mechanisms that determine these results. There is a need also to find out whether it is possible to reduce the risk of cancer, if “owl” voluntarily become a “lark”. It is possible that differences in the probability of cancer in people from these two categories are defined by something more than just time bedtime. (READ MORE)
