Colonic or rectal polyps tend to grow in people who sleep less than six hours a day, a new study published in the journal Cancer reveals. Based on research of 1,240 men and women who answered questions relating to their sleeping habits before undergoing colonoscopy and a number of other tests, this is the first ever study that shows a correlation between sleep and colorectal polyps.
Among the probable reasons put forward as reasons behind the polyps growth for sleep-deprived people were obesity and insulin resistance, and action of the sleep hormone melatonin that inhibits growth of tumors.
Ten percent of cases of patients have cancerous polyps, and the National Cancer Institute estimates that over 140,000 people will be diagnosed with colorectal cancer this year in the US, with 51,000 likely to die from the disease.
