Sleeping less than 6 hours may increase the risk of stroke
Sleeping less than 6 hours a night increases the risk of stroke symptoms among middle-age to older adults with normal weight and at low risk for obstructive sleep apnea, according to a new study that involved 5,666 people and lasted for up to 3 years.
The participants had no history of stroke, transient ischemic attack, stroke symptoms or high risk for obstructive sleep apnea. Researchers recorded the first stroke symptoms, along with demographic information, stroke risk factors, depression symptoms and various health behaviors.
After adjusting for body-mass index (BMI), researchers found a strong connection between daily sleep periods of less than 6 hours and a greater incidence of stroke symptoms for middle-age to older adults, even beyond other risk factors. But there were no association between short sleep periods and stroke symptoms among overweight and obese participants.
‘These results may serve as a preliminary basis for using sleep treatments to prevent the development of stroke’, - said lead author Megan Ruiter, PhD.
