A recent study out of Japan shows that diabetes may be linked to sleep patterns. Researchers found that people who get five or fewer hours of sleep per night are more than five times more likely to get diabetes than people who get seven or more hours of sleep per night. The research team tracked a group of adult males and females for four years. In the end, of the 3,570 participants, 121 of them developed some level of diabetes after the four years. After ruling out any participants who had family history of diabetes it was found that those who were getting five hours of sleep or less were five times more likely to get the disease than the others who were getting seven or more hours of a restful night’s sleep. In addition, a large amount of those who developed diabetes were also working night shift schedules.
