Up early Bring Health Effects Better for Women

Getting up early always brings more goodness, including for women. The new study revealed that those who wake up early have almost half the time to avoid being exposed to breast cancer risk from women who like to stay up late.

Bristol University scientists found that wake-up habits give 40 to 48 percent less chance of developing breast cancer. This number is approximately one case of cancer fewer than every 100 women who have a habit of getting up early.

The study also found an additional risk of breast cancer for women who sleep more than seven to eight hours per night. It is estimated to be equivalent to an additional 20 percent risk for each hour.

To produce this conclusion, researchers used information from nearly 400,000 women who had genetic information in the British Biobank. They are part of the Breast Cancer Association Consortium study.

By looking at about 450 sleep-affiliated genetic markers, such as the chronotype, the amount of sleep needed, and the risk of insomnia, scientists were able to study cancer risk independently. This study could see the risk of being released from confounding factors such as alcohol or smoking or known as the randomization technique.

"What we want to see next is the interaction between our innate preferences, being morning or evening people, and our actual behavior. Some suggest inconsistencies between social hours and our biological clocks can put us at risk of penyaki," said study leader Dr Rebecca Richmond quoted from The Independent, Wednesday (11/7).

However, that does not mean the risk of cancer is fully determined by genetics because modifying behavior can reduce a lot of that risk. These findings add to other studies about the role of sleep patterns that have found cancer rates to be higher among women who work night shifts.

Clinical director at Breast Cancer Care Dr. Emma Pennery stated, the results of the study highlighted the need for further investigation. Because, changing one's sleep habits is not an easy thing, moreover this is related to work, family, and other health conditions.

"More work is needed to understand why sleep characteristics can be associated with breast cancer risk. However, what we know is that maintaining a healthy weight, exercising and drinking alcohol in a reasonable amount, all help reduce risk, "said the figure who was not involved in the study.

While NHS surgical oncology consultant Cliona Kirwan said, the study presented at the National Cancer Research Institute Conference in Glasgow provided further evidence to suggest good sleep patterns. Disrupted sleep patterns may have a role in the development of cancer.

"The use of Mendel randomization in this study allows researchers to examine the causal effects on breast cancer from different sleep patterns by looking at variations in certain genes that are known to be related to sleep characteristics. This helps to avoid misleading conclusions that might be influenced by confounding factors, "Kirwan said.
