Here's another condition to add to the growing list of illnesses associated with poor quality sleep - colon cancer.
According to new research, those who get less than six hours of sleep each night have close to a 50% increase in their risk of developing colorectal adenomas (precursors to cancer tumors) compared to those who sleep for at least seven hours.
Dr Li, one of the authors of the study, claims that the increase in risk due to a lack of sleep is the equivalent of having a parent or sibling with cancer.
All rather worrying - and yet another reason why insomnia deserves more respect, more research and more understanding.
