“Restless, fragmented sleep and irregular sleep patterns have both been linked to elevated cancer risk…”

Sleep Doctor, Michael J Breus, PhD.

According to the Sleep Doctor, Michael J Breus, PhD, people ask him all the time “if I sleep poorly, does my risk of cancer go up?” The Sleep Doctor’s answer? The relationship between sleep and cancer is complicated, but “sleep can be a key preventative strategy that may help reduce your risk of cancer.” He follows that up with, “sleep is now being used as a therapeutic tool in the treatment of cancer.” As such, it seems pretty evident that sleep, at least, helps reduce the risk of cancer. But let’s look a bit deeper, shall we?

Sleeping and Cellular Health

Sleep is essential to the body’s health. When we sleep, our body repairs damaged cells and DNA, grows new and healthy cells, and strengthens our immune system. To emphasize, a study in 2014 found lack of sleep increases damage to DNA, as well as injury and dysfunction to cells. When you connect the study to cancer, one must remember that all types of cancer involve out-of-control growth and replication of damaged cells. So when your lack of sleep slows down the repair process, you’re basically leaving yourself open to damaged cells to stick around longer to replicate and potentially become cancerous.


Multiple studies seem to say so, emphasizing that short sleep may increase breast cancer risk, and a higher risk of colorectal cancer. Additionally, studies show that disrupted sleep may contribute to making cancer more aggressive. As such, finding ways to have more quality sleep is crucial to keeping ourselves healthy.


“Researchers concluded that weighted blankets were effective in improving quality and quantity of sleep for participants with mild to moderate insomnia who had some excessive daytime sleepiness. Thus, these blankets could be beneficial for use by those with general insomnia and mild sleep problems.”
