SAN ANTONIO — We've all heard that not getting enough sleep can have terrible consequences on your health. But as we report in tonight's Verify, the amount of you sleep you get is just as important as the quality of sleep.

Some of us sleep on our back, some our right or left side, and some on our stomachs. But is one certain position the best for your heart?

THE QUESTION

Is it true that sleeping on your side is better for your heart?

THE SOURCES

• Dr. Chelsea Perry, a doctor of dental medicine with Sleep Solutions and Diplomate of the American Board of Dental Sleep Medicine
• Dr. William Lu, the Medical Director of Dreem Health
• Dr. Jacob Teitelbaum, a board certified integrative physician and author of "From Fatigued to Fantastic!"

THE ANSWER

TRUE

WHAT WE FOUND

Dr. Perry says sleeping on your back is the worst position if you have sleep apnea because sleep apnea has been linked to heart disease and atrial fibrillation. 

"Usually as part of my treatment plan I'll advise my patients to try some device that will help them sleep on their side through some kind of pillow or even sleep trainers that help you - just subconsciously remind you to not sleep on your back," he said. 

Dr. Lu, whom agrees with this assessment added, "What we know is that sleep apnea can potentially cause heart issues. And so besides sleeping, we can sometimes avoid snoring or reduce the severity of sleep apnea." 

Dr. Teitelbaum also says sleeping on your side could help you with indigestion and heartburn. 

"It can help a little bit. But again, the position of this minor factor, if you keep your head of your bed elevated a bit, that will help decrease nighttime acid reflux," he said.

So yes, it is true. Sleeping on your side is better for your heart.

Dr. Teitelbaum says if you are out of breath lying in bed flat, that could be a sign of heart failure and to see a doctor right away.
