One out of eight women develop breast cancer at some point in their lives and nearly every woman knows someone who has been affected by it if she herself hasn’t. While there is no telling exactly how or why the killer disease chooses its victims, there are ways to lower that risk.

Besides maintaining a healthy diet and exercise routine to lower cancer risk, a new research by the National Cancer Institute of America has found significant correlation between sleeping habits and cancer risk. Night owls, you may want to pay attention to this.

The research, which encompassed data from several hundred thousand women, found that women who wake up earlier in the day to go about their routine at that time had a lower risk of developing breast cancer. In fact, a preference for mornings reduces the risk of breast cancer by a whopping 40%.

Additionally, women who sleep longer than the recommended seven to eight hours had a 20% increased risk of breast cancer per additional hour of sleep. That’s pretty disheartening considering all the weekends we’ve chosen to sleep in or turn the alarm off completely..

With all that said, it’s not strictly about the time you wake up daily. The research attests correlation between the two, not direct causation. The findings aren’t absolute, but sleep is inherent to health so you may as well develop a good relationship with it.
