kissing is healthy

A person shares up to 100,000 kisses in a 70-year life. And these caresses are well invested: kissing is not only fun, it is also healthy. And if a kiss is intense enough, it even burns calories. But   kissing also has an effect on blood pressure, the immune system and the development of stress hormones. Find out what kissing does to the body, why kissing is so healthy and in which cases kissing can also pose a risk.

What kissing does to the body

A deep kiss turns the body upside down and triggers violent chemical reactions: pulse and body temperature soar,  metabolism  and blood circulation are boosted, endorphins make you forget pain, the immune system runs at full speed:

  • Blood pressure rises to 150 mmHg. Regular kissing can even lower blood pressure by expanding the blood vessels.
  • 36 historical muscles are moved.
  • The heart rate increases to 110 beats per minute in men and 108 in women.
  • Kissing releases the cuddle hormone oxytocin, which strengthens the bond between two people.

By the way:  There is a simple reason why noses don’t touch when kissing: most people instinctively approach their partner with their heads tilted to the right.

Healthy effects of kissing

The topic of kissing has already encouraged many scientists to do research. Here are numerous positive facts that have come to light in recent years:

  • Kissing helps relieve stress. This is because happiness hormones such as  serotonin  and endorphins are increasingly produced.
  • Kissing stimulates salivation. This has advantages for the teeth, because saliva contains calcium and the trace element  phosphorus . Absorbed by the tooth enamel, these substances make it hard and strong against tooth decay.
  • Kissing can relieve pain. This is probably due to the increased formation of the hormone oxytocin.
  • If you kiss a lot, you strengthen  your immune system because the formation of neuropeptides is stimulated. These activate the natural killer cells.
  • The kiss acts like a kind of oral vaccination that kissers give each other. Because the saliva contains up to 22,000 different types of bacteria. If these are exchanged during a kiss, impulses for the formation of defenses and antibodies are sent out.
  • Kissing can relieve tension and is said to help prevent annoying  hiccups  , since kissing increases the amount of CO2 in the blood.
  • Kissing connects: Kissing releases the cuddling hormone oxytocin, which strengthens the bond between two people.

How many calories do you burn kissing?

A frequently mentioned health aspect is that kissing  can burn calories  . That’s actually true. Because kissing speeds up the heartbeat and ensures that hormones are released in the body. Both increase the body’s energy requirements. In addition, about 36 facial muscles are “trained” with a kiss.

A normal kiss burns around 12 calories (50 kilojoules) per minute, and a passionate French kiss even burns up to 20 calories (84 kilojoules).

Can kisses be dangerous?

What serves to harden one person can have negative consequences for the other: meningococci or cytomegaloviruses can be transmitted when kissing. The Epstein-Barr virus can also be transmitted in this way. This can   trigger glandular fever . The disease is therefore popularly referred to as “kissing disease”.

The bacterium  Helicobacter pylori  can also be found in the saliva. According to researchers, it causes many  stomach ulcers , but can also promote inflammation of the gastric mucosa and even stomach cancer. However, scientists now strongly doubt that the amount transferred when kissing is sufficient to trigger a serious illness. The bacterium probably only remains in the oral cavity temporarily.

However, people with food allergies need to be careful: If the other person has eaten even the smallest amount of food that triggers the allergy, an intense kiss shortly afterwards can lead to an allergic reaction. This is particularly common with nut allergies.
