Abnormal Sleep

Recommendation: Get Enough Sleep

Abnormal sleep is another risk factor for type 2 diabetes. Poor sleep has been linked to metabolic problems and increased hunger. Sleeping for too few hours (less than 5 hours a night) and too many hours (more than 9 hours a night) is associated with increased risk of diabetes.1 Sleep apnea, a sleep disorder during which breathing obstructions lead to intermittent sleep, is very common among obese adults and may further increase risk of type 2 diabetes.2-3 Working night shifts, which disrupts sleep rhythms, has also been associated with an increased risk of type 2 diabetes.4
