Women Rising Early Have Lower Risk of Breast Cancer

"In other words, it may not be the case that changing your habits changes your risk of breast cancer; it may be more complex than that," she noted

Women who begin their day early are likely to have a lower of risk breast cancer, than late beginners, suggests a research.

The study found that a preference for mornings reduced the risk of breast cancer by 40 per cent compared with being an evening type.

It also found that women who slept longer than the recommended seven to eight hours had a 20 per cent increased risk of the disease per additional hour slept.

“The findings of a protective effect of morning preference on breast cancer risk in this study are consistent with previous research highlighting a role for night shift work and exposure to ‘light-at-night’ as risk factors for breast cancer,” said Rebecca Richmond, a research student in the Cancer Research UK.

“We know already that night shift work is associated with worse mental and physical health. This study provides further evidence to suggest disrupted sleep patterns may have a role in cancer development,” she added.

The results were presented at the 2018 NCRI Cancer Conference in Glasgow.

For the study, the team looked at data from 180,215 women, and 228,951 women part of a genome-wide association study of breast cancer.

Using genetic variants associated with people’s preference for morning or evening, sleep duration and insomnia, they investigated whether these sleep traits have a causal contribution to the risk of developing breast cancer.

They also found some evidence for a causal effect of increased sleep duration and sleep fragmentation on breast cancer.

The researchers believe their findings have implications for policy-makers and employers.

“These findings have potential policy implications for influencing sleep habits of the general population in order to improve health and reduce risk of breast cancer among women,” Richmond said.

Richmond said: “We would like to do further work to investigate the mechanisms underpinning these results, as the estimates obtained are based on questions related to morning or evening preference rather than actually whether people get up earlier or later in the day.

“In other words, it may not be the case that changing your habits changes your risk of breast cancer; it may be more complex than that,” she noted. (IANS)

Here’s Why Women Should Not Dine After 6 PM

Women who dine late in the evening are likely to develop heart diseases

Women who consume a higher proportion of their daily calories late in the evening are more likely to be at risk of cardiovascular disease than women who do not, researchers have warned.

For the study, the research team assessed the cardiovascular health of 112 women using the American Heart Association’s Life’s Simple 7 measures at the beginning of the study and one year later.

Life’s Simple 7 represents the risk factors that people can improve through lifestyle changes to help achieve ideal cardiovascular health and include not smoking, being physically active, eating healthy foods and controlling body weight, along with measuring cholesterol, blood pressure and blood sugar levels.

A heart health score based on meeting the Life’s Simple 7 was computed.

“The preliminary results indicate that intentional eating that is mindful of the timing and proportion of calories in evening meals may represent a simple, modifiable behaviour that can help lower heart disease risk,” said study lead author Nour Makarem from Columbia University in the US.

During the study, participants of the study kept electronic food diaries by computer or cell phone to report what, how much and when they ate for one week at the beginning of the study and for one week 12 months later.

Data from the food diary completed by each woman was used to determine the relationship between heart health and the timing of when they ate.

Researchers found that, after 6 p.m. with every one per cent calories consumed heart health declined, especially for women.

These women were found more likely to have higher blood pressure, higher body mass index and poorer long-term control of blood sugar.

Similar findings occurred with every one per cent increase in calories consumed after 8 p.m.

“It is never too early to start thinking about your heart health whether you’re 20 or 30 or 40 or moving into the 60s and 70s. If you’re healthy now or if you have heart disease, you can always do more. That goes along with being heart smart and heart healthy,” said study researcher Kristin Newby, Professor at Duke University.

The study is scheduled to be presented at the American Heart Association’s Scientific Sessions 2019 from November 16-18 in Philadelphia, US. (IANS)
