SWEET SPOT OF SLEEP
Steve & Bonnie: According to findings presented at this year's European Society of Cardiology Congress, the sweet spot of six to eight hours sleep a night is most beneficial for heart health. More or less is detrimental.
The study investigated the relationship between sleep duration and cardiovascular disease. The analysis included more than one million adults without cardiovascular disease.
Two groups, one with short (less than six hours) and another with long (more than eight hours) nightly sleep duration, were compared to the reference group (six to eight hours).
The researchers found that both short and long sleepers had a greater risk of developing or dying from coronary artery disease or stroke. Compared to adults who slept six to eight hours a night, short and long sleepers had 11% and 33% greater risks, respectively, of developing or dying from coronary artery disease or stroke during an average follow-up of 9.3 years.
