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.

Light Physical Activity May Lower CVD Risk in Women: Study

Most people do not think of folding clothes or walking to the mailbox as physical activity of any kind

While strolling or running are beneficial for heart health, light physical activity, such as gardening and folding clothes, may also lower the risk of cardiovascular diseases (CVD) in older women, say researchers.

The study showed that such activities might be enough to significantly reduce stroke or heart failure by up to 22 per cent and the risk of heart attack or coronary death by as much as 42 per cent.

The association was strong across all racial and ethnic groups, noted the study published in the journal JAMA Network Open.

“The higher the amount of activity, the lower the risk,” said co-author Andrea LaCroix, Researcher at the University of California, San Diego.

“And the risk reduction showed regardless of the women’s overall health status, functional ability or even age. In other words, the association with light physical activity was apparent regardless of these other factors,” LaCroix added.

For the study, researchers studied nearly 6,000 women aged 63 to 97. They were made to wear a device which measured their movement 24 hours a day for seven consecutive days. The device was also calibrated by age to distinguish between light, and moderate-to-vigorous physical activity.

“This study suggests that for older women, any and all movement counts towards better cardiovascular health,” said David Goff, Director at National Heart, Lung, and Blood Institute (NHLBI) in the US. (IANS)
