According to new research, falling in love can help a variety of physical conditions like high blood pressure and can actually increase brain activity. Researchers at the university concluded that falling in love is the “result of activity in 12 areas of the brain working together.” They have found that just by looking at a loved one can actually trigger the release of dopamine, which is one of the body’s natural pain killers. A 2006 study also shows that there are benefits to kissing – 30 minutes of kissing reduces the production of histamine which triggers allergy symptoms.
