Early waking women are less likely to develop breast cancer


Women who like to wake up early and enjoy the wonderful morning to do their daily activities are from 40% to 48% less likely to develop breast cancer than those who prefer the night.

This is the conclusion of a study by researchers from the University of Bristol in the United Kingdom that also discovered evidence of a causal relationship between sleeping more time and developing the disease.

To carry out the research, data from more than 180,000 women included in the Biobank project of the United Kingdom, which provides data from medical research in various areas with about half a million people, has been compared. The team also analyzed data from more than 220,000 women who participated in an international genetic study conducted by the Association of Breast Cancer of the United Kingdom (Consortium of Consortium of the Breast Cancer Association).

In addition to demonstrating a greater likelihood of developing cancer in women who prefer the night, the results analysis has shown that those who sleep more than seven or eight hours a day increase their chances of developing the disease by 20% for each additional hour of sleep .

According to the researchers who presented the results at the conference of the National Cancer Research Institute (NCRI) in Glasgow, Scotland, there is a genetic predisposition for people to stop and get up early or feel more sleep in the morning and more energetic by night.

Rebecca Richmond, lead author of the study, explained that the team used genetic variants associated with people's preference in the morning or at night, but also the duration of sleep and insomnia, to see if these factors contributed or contributed to the development of cancer. from the breast

She said that more studies are needed to really understand what motivates the development of breast cancer since the results were based on issues related to the preference of tomorrow or night and not when people wake up. This means that changing the circadian rhythm and sleeping habits may not be enough to lessen the risk of breast cancer.
