However, donating blood regularly may lower iron stores, according to a 2013 study. This may reduce the risk of heart attack. High body iron stores are believed to increase the risk of heart attack.
Regular blood donations were thought to lower blood pressure, but a 2017 study suggests these observations are deceiving and are not a real physiological response.
