What's Love Got to Do With Mental Health?

On Valentine's Day, people's thoughts often turn to love. And whether you spend your day focusing on the hearts and flowers related to romantic love or the love from friends, family, or pets, both all of love can have an important influence on mental health. 

In honor of Valentine's Day, we take this opportunity to point to a few interesting facts related to love and mental health. Love is important not just on Valentine's Day, but throughout the year. 

People who are happy with their marriages may feel less pain. According to a study of octogenarians, those who reported having happy marriages stated their mood didn't suffer even on days they reported more physical pain. Alternately, those who said they were in unhappy marriages reported more physical and emotional pain. 

Having strong relationships may lead to a healthier and longer life. According to the Harvard Study of Adult Development, the longest longitudinal study of adult happiness, individuals who have warm and supportive connections tended to be the happiest and stayed healthiest as they aged. Quality relationships were the strongest predictor of which individuals would report being happy and healthy as they got older. The psychologists behind this study believe that people need to exercise social fitness just as you would physical fitness by putting in regular work to strengthen relationships. 

Your brain may be responsible for any bad decisions you've made early in a relationship. Although your body will release feel-good chemicals like oxytocin and dopamine when you are in the early stages of a romantic relationship, your brain deactivates the neural pathway for emotions like fear and judgment. This essentially shuts down the ability to make critical assessments of people which explains why people don't always see their mates' flaws until those initial intense feelings calm down. 

The majority of singles aren't looking for romance. If you aren't in a relationship and don't want to be, you are not alone! According to a recent study from Pew Research, 56% of singles said they are not looking for a relationship. Near three-quarters of the group who is not looking to date say it is because they enjoy being single. Of those who are dating, nearly half report that their love life is a cause of stress, saying it is harder to date today than it was 10 years ago. 

There are neurobiological differences between romantic and parental love. Different areas of the brain are involved in parental versus romantic love. In romantic love, the hypothalamus is activated, which is responsible for testosterone and other hormones. Furthermore, part of the reward system that gets activated in romantic love comes from the knowledge that your love is being reciprocated by another person. This brain area is not as important in parental love which explains why parents can love their babies even before they can smile back at them.
