“A calm heart is the life of the fleshly organism.”​—PROVERBS 14:30.

Concerning a calm heart versus one given to anger, the Journal of the American College of Cardiology states: “Current findings suggest a harmful association between anger and hostility and CHD [coronary heart disease].” Hence, the Journal notes: “Successful prevention and treatment of CHD might involve . . . not only conventional physical and pharmacological therapies, but also psychological management focusing on anger and hostility.” Simply put, a calm heart fosters good health, just as the Bible says.
