A team of researchers from the University of Colorado Boulder in the United States of America, have explained, in a new study, how sleeplessness affects blood circulation in the body by aiding a build-up of fatty deposits in the arteries, thereby increasing a person’s risk of stroke or a heart attack.
According to medicalnewstoday.com, the findings of the researchers, published in Experimental Physiology, tied sleeplessness to changes in the blood levels of micro RNA, MiRNA, non-coding molecules that help regulate protein expression.
The researchers collected blood samples from 24 healthy participants whose ages fell between 44 and 62 years, who also provided information about their sleeping habits. About half of the participants reported sleeping seven and 8.5 hours per night, while the rest said they only slept for five or six hours per night. Read more
