5 Scientific Health Benefits of Kissing

4. Lowers stress


When you are stressed out, your body produces lots of cortisol (a stress hormone) which makes you feel cranky and on edge. Kissing actually lowers the levels of cortisol in the body. Also, because of the blood vessel dilation, kissing can actually lower your blood pressure. If you are stressed out and exhausted after a long day of work and dealing with the kids, just kiss your spouse to feel better!
