Bhubaneswar: People who limit their sleep hours are at high risk of developing heart disease.
A study published in the journal Experimental Physiology, shows that people who sleep fewer than seven hours per night have lower blood levels of three physiological regulators, or microRNAs, which influence gene expression and play a key role in maintaining vascular health.
Besides, the researchers have also opined that less than seven hours of sleep may trigger the risk of developing cardiovascular disease (CVD) and coronary diseases.
For the study, the research team took blood samples from a small group of healthy men and women, age 44 to 62, who had filled out questionnaires about their sleep habits.
While half of the participants slept seven to 8.5 hours nightly, the other half slept five to 6.8 hours every night.
The study revealed that people with insufficient sleep had 40 to 60 per cent lower circulating levels of miR-125A, miR-126, and miR-146a than those who slept enough.
