People who have irregular sleep schedules may have an increased risk of dying from cancer and heart disease, compared with people who have regular sleep schedules, according to a seven-year study of middle-age and older adults.
Scientists have previously found that a lack of sleep may increase the risk of dying from any cause, but it was unclear whether irregular sleep schedules similarly affected mortality rates. Now, new research, which was posted April 17 on the preprint database medRxiv and has yet to be peer-reviewed, suggests they do.
