Being in a state of happiness gives phenomenal benefits to your heart, In a study called Positive affect and biological function in everyday life Andrew Steptoe and JaneWardle found that happiness lowers heart rate and blood pressure. “In the study, participants rated their happiness over 30 times in one day and then again three years later. The initially happiest participants had a lower heart rate on follow-up (about six beats slower per minute), and the happiest participants during the follow-up had better blood pressure.” Research has also found a link between happiness and another measure of heart health: heart rate variability, which refers to the time interval between heartbeats. In 2008 Bhattacharyya MR , Whitehead DL, Rakhit R, and Steptoe A monitored 76 patients suspected to have coronary artery disease. Was happiness linked to healthier hearts even among people who might have heart problems?
