Love lowers your blood pressure
Love is proven to lower blood pressure and decrease stress levels. A 2007 found that happily married couples had lower blood pressure levels than unmarried people, while unhappily married couples had higher blood pressure than both groups [US Department of Health and Human Services].
This is not exclusive to love between romantic couples – close friendships with loving friends have the same effect! A 2010 study found that people with quality relationships had lower blood pressure than their less social counterparts. In fact, the loneliest people in the study saw a 14.4-point rise in systolic blood pressure when compared to their popular peers [Journal of Psychology and Aging].
