Those who have short sleep duration, that is less than 7 hours per night and have poor sleep quality are associated with cardiovascular morbidity and metabolic disorders such as glucose intolerance, which also will lead to obesity, diabetes, heart disease, and hypertension. Individuals who experience shorter sleep duration are at 1.48 times greater risk of developing and dying of coronary heart disease than those who have sufficient sleep and 1.15 times more likely to have a stroke.


Adults who sleep less than 7 hours per night also have greater difficulty in concentrating, remembering, and performing daily activities than those who sleep 7 to 9 hours per night.

In 2005, drowsy driving contributed to 100,000 motor vehicle accidents and 15,000 deaths.
