NEW YORK (Reuters Health) – A new study shows that women who get up early in the morning are less likely to develop breast cancer than others.
In a study of more than 400,000 women, scientists at Bristol University found that women who slept too long (more than 8 hours) had an additional 20% risk of cancer per hour of extra sleep.
An explanation could be the importance of sleeping well and waking up early in the morning. Women who are more active in the evening than severe sleep disorders are more likely to suffer from cancer.
According to Daily Mail, night-time sleep affects the woman's biological clock and increases risk, as evidenced by previous studies showing that working nights and exposing more to night-time industrial light increases the risk incidence of cancer.
The research team, which presented the results at the National Cancer Research Institute Conference in Glasgow, analyzed and studied female genes.
"We want to do more work to study the mechanisms that support the results," said Rebecca Richmond, MD. "The estimates obtained are based on questions relating to morning and evening sleep, and could be more complex than the usual change for breast cancer risk in women."
"Changing sleep patterns is not as easy as other proven risk reduction options because they are often an integral part of jobs, parenting or other health problems," said Dr. Emma Penry. from the Breast Cancer Society.
The study found that women diagnosed early were 48% less likely to develop breast cancer.
