Sleeping in total darkness can reduce cancer risk, thanks to melatonin. Melatonin, a hormone that regulates sleep and is produced in a daily cycle, is only made by the pineal gland in the brain in the dark. Research has shown that melatonin is a strong antioxidant, can enhance immune function, can inhibit the growth of and actually kill cancer cells.

Since melatonin is made in the dark, it is important to sleep in total darkness. Even low levels of light and short duration of light exposure impair its production. That means that sleeping with any lights on, the TV on, lights shining through bedroom windows, or even turning on the light at night when going to the bathroom will inhibit melatonin production. So…for better health, sleep in TOTAL darkness.
 
 
New breast cancer screening guidelines recommend against routine mammograms for healthy women in their 40s due to the number of false positives. Although controversial, I can appreciate the decision. As a naturopathic physician, I strongly believe in the basic medical tenet “first do no harm” and breast trauma (squishing) and radiation are harmful. The decision to do a mammogram should be an individualized and educated decision.

The bottom line is prevention. Naturopathic physicians are experts in preventive medicine. Generally speaking, there is much to be done preventively. Regarding breast cancer risk assessment, I highly recommend vitamin D level testing and extensive hormone testing that includes estrone metabolites. Contact me, or your local naturopathic physician, for a complete preventive wellness check, including vitamin and hormone testing.
