According to Ten, during a kiss, the partners’ breathing accelerates, and their blood vessels dilate, leading to more intense oxygenation of their bodies. Hormones such as adrenaline and oxytocin are released, and the brain actively produces endorphins (happiness hormones), which increases satisfaction levels and reduces pain.
Additionally, the level of cortisol (the stress hormone) decreases, and blood cholesterol levels drop. During a kiss, the saliva’s calcium and phosphorus levels rise, which strengthens tooth enamel, the doctor explained.
Ten also noted the benefits of kissing for facial muscles, as more than 30 muscles are actively engaged in the process, leading to increased blood flow to the facial tissues and promoting skin elasticity.
Today, July 6, marks World Kiss Day—an unofficial international holiday celebrated by enthusiasts in over 60 countries.
One version of the holiday’s origin traces it back to the United Kingdom in the late 20th century, with some sources pinpointing 1986 as the exact year when it was initially called National Kissing Day.
Gradually, the tradition of celebrating Kiss Day spread worldwide. The holiday was first recognized internationally in 2006, after which it became known as International Kissing Day.
On this day, it is customary to give a kiss to your loved one.
