Shift Workers Have Higher Cancer Rates

Shift work is once again linked to an increased risk for cancer.
Multiple studies have linked night shift work to an increased risk for cancer.1-7
Now a new study in the American Journal of Epidemiology links rotating shift work
to an increased risk for prostate cancer in men.

Dr. Osborne’s Comment…
Improper sleep habits are a major contributing factor to poor health.  Many
studies have linked inadequate sleep to increased risk for cancer, autoimmune
diseases, high blood pressure, diabetes, hormone disruption, and more.  The
body has a natural circadian rhythm.  The hormone melatonin is secreted in
higher amounts through out the night during sleep.  This hormone has
antioxidant properties as well as cancer suppressing effects.  Inadequate sleep
suppresses melatonin pathways and diminishes its beneficial effects.
Studies show that the most beneficial sleep is between the hours of 10
pm and 2 am
Your body repairs and heals itself during sleep.
Artificial light sources in the bedroom should be turned off to prevent
disruptive sleep.
Keep in mind that some people require more sleep than others.
Generally speaking people require between 6 and 10 hours of sleep.
