Poor sleeping patterns could be a contributing factor to cancer, a new test on mice suggests.
Researchers warn that though further testing on humans is needed, women with a family history of breast cancer should avoid working shifts that contribute to poor sleep patterns. The study also found that the mice with poor sleeping patterns were 20 percent heavier, despite consuming the same diet as the other mice.
Previous studies in people have indicated that shift workers and flight attendants have a higher risk of diseases like breast cancer.
Experts say the apparent link could be attributed to several factors, including the disruption of the body’s internal rhythm, more commonly referred to as the “body clock.” However, they warn that any link at all needs further research and that the cancer development could be due to other factors such as social class and activity level.
