Negative emotions have been linked to increases in blood pressure.
Here is a recent study concerning positive emotions and lower blood pressure. The objective of the researchers was to test the hypothesis that high positive emotion would be associated with lower blood pressure in older adults.
The study included 2564 Mexican Americans aged 65 or older living in one of five southwestern states.
Their findings indicated an association between high positive emotion and lower blood pressure among older Mexican Americans. They proposed that targeting the emotional health of older adults might be considered part of non-pharmacologic hypertension treatment programs or as part of adjunctive therapy for those on antihypertensive medication.
