Forget the medicine cabinet— romantic relationships can be a ticket to good healthLove promotes health. Esch, T., Stefano, G.B. Charité-University Medicine Berlin, Institute for General Practice and Family Medicine, Berlin, Germany. Neuroendocrinology letters, 2005 Jun;26(3):264-7.. (Thanks, sweetie.) But is Cupid’s bow a double-edged sword? We took a closer look at love— from long-term relationships to casual encounters, marriage to heartbreak— to see how it really affects our health.

Heart Healthy — The Need-to-Know

Love isn’t all about the butterflies. There are chemical processes in the brain that affect how we feelThe Neurobiology of Love. Esch, T., Stefano, G.B. Charité-University Medicine Berlin, Institute for General Practice and Family Medicine, Berlin, Germany. Neuroendocrinology Letters, 2005 Jun;26(3):175-92.. When we’re with a significant other, the body releases hormones, like oxytocin and dopamine, that signal feelings of trust, pleasure, and reward. And all that happens in the brain may be good for the heart— literally. In one study, researchers found people’s blood pressure was lower when they were with a romantic partner than when they were interacting with anyone else. (Guess they weren’t fighting…)Partner interactions are associated with reduced blood pressure in the natural environment: ambulatory monitoring evidence from a healthy, multiethnic adult sample. Gump, B.B., Polk, D.E., Kamarck, T.W., et al. Department of Psychology, State University of New York at Oswego, New York. Psychosomatic Medicine, 2001 May-Jun;63(3):423-33.. Scientists suggest blood pressure’s lower in these situations because romantic partners feel familiar and comfortable with each other. Yet, even new relationships have their advantages— researchers discovered fresh love may shield against stressLove alters autonomic reactivity to emotions. Schneiderman, I, Zilberstein-Kra, Y., Leckman, J.F., et al. Gonda Multidisciplinary Brain Research Center, Bar-Ilan University, Ramat-Gan, Israel. Emotion, 2011 Dec;11(6):1314-21.. Oh, the joys of the “honeymoon” stage.

Love Lockdown — Your Action Plan

In most cases, love and wellness go hand-in-hand. But beware: People in unsupportive and harmful relationships are at greater risk for developing heart problems, depression, and a weaker immune systemSocial relationships and health: a flashpoint for health policy. Umberson, D., Montez, J.K. University of Texas at Austin, Department of Sociology, Austin, TX. Journal of Health & Social Behavior, 2010;51 Suppl:S54-66.. And with any relationship comes the risk of heartbreak, which really does hurt,as scientists uncovered neurological similarities between feelings of social rejection and physical pain. And it may not be a good idea to get hitched too soon. When researchers looked at marriage among couples up to 26 years old, they found a link between tying the knot and a higher BMIMarriage and Health in the Transition to Adulthood: Evidence for African Americans in Add Health. Harris, K.M., Lee, H, Deleone, F.Yl. Carolina Population Center and Department of Sociology University of North Carolina at Chapel Hill, Chapel Hill, North Carolina. Journal of Family Issues, 2010 Aug;31(8):1106-1143.. And, sorry gents, early marriage was also associated with an increased rate of depression in African American men and smoking in white men. Maybe their spouses were Housewives? So here are some tips to take advantage of the potential health benefits of Cupid’s arrow, giving us another reason to thank a loved one this Valentine’s Day (and every day that follows!):

  • Write a love letter. Forget texting— one study found writing love letters can reduce cholesterol. Signed, sealed, delivered— it benefits both parties!
  • Grab a hand. Holding hands with a significant other can reduce stress more than holding a stranger’s (which would be weird anyway)Lending a hand: social regulation of the neural response to threat. Coan, J.A., Schaefer, H.S., Davidson, R.J. Department of Psychology, University of Virginia, Charlottesville, VA. Psychological Science, 2006 Dec;17(12):1032-9.. Looks likethe Beatles were onto something.
  • Hit the gym (together).
