A new study has found that losing as little as one hour of sleep a night is associated with higher blood pressure in pre-teens and teenagers. Frequent or ongoing sleep loss, which can result in higher blood pressure, could put sleep-deprived youths at greater risk for cardiovascular disease in later years.
Researchers from the Chinese University of Hong Kong recruited 143 children ages 10 to 18, who had participated in an earlier study on sleep apnea. The participants were healthy, neither overweight nor obese, and they did not have sleep apnea. (Sleep apnea is a condition characterized by interrupted or shallow breathing when a person is sleeping; the disorder has been linked to higher blood pressure.)
