Kissing does wonders for you; it releases oxytocin, which makes you feel a sense of comfort and bonding, and dopamine, which activates your brain's reward center.
Those butterflies in your stomach? They come from epinephrine and norepinephrine, which increase your heartbeat and send oxygenated blood to your brain.
Some studies have even shown that kissing can cause a reduction in the stress hormone cortisol, which could help lower your blood pressure.
Share a kiss every day lasts at least six seconds. Why six seconds? Because it's long enough to feel romantic.
Plus, as John Gottman likes to say, "A six-second kiss is a kiss with potential. It's a kiss worth coming home to."
