Women who are early in the day can have a lower level of breast cancer, suggesting a study.
The study showed that the morning morning morning decreased the risk of breast cancer by 40 percent.
Additionally, over eight to eight hours of sleeping women increased the risk of an additional 20% of sleep time.
"The findings of the protective effects of morning preference on breast cancer correspond to recent studies that have a night-night effect on the night shift and breast cancer," said Rebecca Richmond, a research fellow at the Cancer Research UK in the UK.
"We know that night shift work depends on the poor mentality and health, which can lead to the development of malignant neoplasms," he said.
The results are presented at the RCC Conference in Glasgow in 2018.
The team reviewed the data obtained from 180,215 women and 228,951 women at the Genomic Council for the Study of Breast Cancer Association.
In the morning or in the evening, using genetic guidelines for sleep, sleep duration and insomnia, they have discovered that these sleep patterns can lead to the development of breast cancer.
They also identified the long-term sleep duration and the causes of sleep fragmentation in breast cancer.
According to the researchers, their outcome will affect politicians and employers.
"These studies have potential political consequences for improving health and affecting the general population's sleep habits to reduce the risk of breast cancer among women," Richmond said.
Richmond: "We want to work on further research to find out the results, because the information is based on questions about early morning or evening choices, not sooner or later.
"In other words, changing your habits can not change the risk of breast cancer, which can be even more challenging," he said.
