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.
