I wonder why we would never drink someone’s saliva but would kiss someone. When kissing we exchange saliva in the mouth. Kissing has benefits too and these include:
Good for your teeth—as long as the two of you are fairly hygienic.
Gives your immune system a boost
More than 700 types of bacteria have been found in the human mouth, but no two people have the exact same makeup of oral germs, so exchanging saliva with someone can introduce new “foreign” bacteria into your body, which isn’t a bad thing.
One of the primary health benefits of kissing is its ability to release the hormone (known as the love hormone) whose ability to induce a sense of calm, relaxation, and bonding in humans.
Helps delay signs of ageing.
Increases your sex drive.
Dilates your blood vessels.
This helps reduce your blood pressure.
Helps soothe headaches.
Prevents cavities by increasing saliva production.
Kissing stimulates your salivary glands, which increases saliva production. Saliva lubricates your mouth, aids in swallowing, and helps keep food debris from sticking to your teeth, which can help prevent tooth decay and cavities.
