Women who sleep a lot have a higher risk of cancer

According to specialists, women who love lying down to sleep for a long time are more likely to develop breast cancer.

Although it is true, the rush, the responsibilities at home, work, children, and so on, make most of the women finish their day exhausted, and look for a moment to rest at least a nap. However, it was discovered that women who sleep a lot have a higher risk of cancer. 

According to a recent study, women who love lying down to sleep for longer during the day, have a greater risk of breast cancer.

This was determined by specialists from the University of Bristol, who were responsible for analyzing the relationship between sleep patterns and breast cancer in women, showing that women who remain active from the beginning of the day until the end, they have a lower risk of having breast cancer, compared to those who usually go to bed between hours.


This was determined by analyzing the behavior of 409 thousand166 women, some who are already going through the disease, and others who do not.

“Using genetic variants associated with people’s preference in the morning or afternoon, sleep duration, and insomnia. We investigated whether these sleep lapses contributed to the development of breast cancer,” explained by Dr. Rebecca Richmond.

The study revealed that women who preferred to sleep in the morning reduced the risk of the disease by 40%, compared to those who take naps in the afternoon.

Women who sleep a lot have a higher risk of cancer. 

They also discovered that women who sleep more than 7 or 8 hours at night, increased their risk of breast cancer for every hour more than they sleep.

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

“We would like to use genetic data from large populations to better understand how the division of the body’s natural clock can contribute to the risk of breast cancer,” they concluded.
