In all human cultures premastication/kiss-feeding or kissing between mother and infant has been observed in all with kissing believed to be a socially ritualized form of feeding premasticated food.

Chewing: Ingestion 1 Amylase in saliva chemically digests starch in the food. The mixing process is lubricated by mucin, a slippery protein in saliva. Each mouthful takes approximately 30–60 seconds.

Only certain STDs, or sexually transmitted infections (STIs), are transmittable through kissing. Two common ones are herpes simplex virus (HSV) and cytomegalovirus (CMV). Kissing can be one of the most exciting parts of a relationship. But you may also feel wary of kissing if you’re with someone for the first time.

Experts advise brushing your teeth and waiting at least 4 hours before kissing someone if you think you ate a food that person may be allergic to.

In rare cases, people have been known to have allergic reactions to proteins in their partner’s semen (semen allergy). Semen allergy isn’t a direct cause of infertility. Signs and symptoms of semen allergy include redness, burning and swelling where the semen has contacted the skin, usually in the outer genital area.

It turns out that their partners’ saliva is excreting the allergen hours after the food or medicine has been absorbed by their body. ‘Kissing’ allergies are most commonly found in people who have food or medication allergies. Symptoms include swelling of the lips or throat, rash, hives, itching and wheezing.

Kissing and your health

• Kissing can transmit many germs, including those that cause cold sores, glandular fever and tooth decay.
• Saliva can transmit various diseases, which means that kissing is a small but significant health risk.
• It’s not all doom and gloom.

The suction from your partner’s mouth causes damage to the capillaries, which are small blood vessels under your skin. This damage causes your capillaries to leak blood, but the blood doesn’t have anywhere to go. As a result, it gets trapped under your skin, where it appears purple.

Truth: You can get a cold sore by kissing. “One of the most common ways the virus is spread is through kissing, because the virus frequently occurs around the mouth and the lips,” said Joshua Zeichner, MD, a New York City-based dermatologist. Even if you don’t see the sores, the virus can still be contagious.

when you kiss your partner passionately, not only do you exchange bacteria and mucus, you also impart some of your genetic code. No matter how fleeting the encounter, the DNA will hang around in their mouth for at least an hour.

Kissing causes a chemical reaction in your brain, including a burst of the hormone oxytocin. It’s often referred to as the “love hormone,” because it stirs up feelings of affection and attachment. According to a 2013 study, oxytocin is particularly important in helping men bond with a partner and stay monogamous.

“During a really, really passionate kiss, you might burn two calories a minute — double your metabolic rate,” he says. (This compares to 11.2 calories per minute you burn jogging on a treadmill.)

An hour-long massage can burn more calories than you might think — 230 calories — the same as an hour of light weight training. And an hour of passionate playtime kills 270 calories, which would burn off a frosted cupcake.

During a kiss, this lip sensitivity causes our brain to create a chemical cocktail that can give us a natural high. The dopamine released during a kiss can stimulate the same area of the brain activated by heroin and cocaine. As a result, we experience feelings of euphoria and addictive behaviour.

On average, you can expect to burn 2 to 3 calories per minute with simple kissing and 5 to 26 calories per minute engaging in passionate kissing, although we’re betting it’s closer to the 2- to 3-calorie mark.

Here’s some news worth cuddling up to: Science shows that kissing, hugging, snuggling, and holding hands produce more than just magical moments. They can actually boost overall health, helping you lose weight, lower blood pressure, fight off sickness, and more.

Cuddling is a love language all its own. Hugging, snuggling, massage, and kissing all fall under the cuddling umbrella. There’s no right or wrong way to cuddle, but these common cuddling positions can pave the way to an epic cuddling session.

When you don’t get enough physical touch, you can become stressed, anxious, or depressed. As a response to stress, your body makes a hormone called cortisol. This can cause your heart rate, blood pressure, muscle tension, and breathing rate to go up, with bad effects for your immune and digestive systems.

One of the biggest things touch can do is reduce such stress, allowing the immune system to work the way it should. Touch can also calm certain bodily functions , such as your heart rate and blood pressure. It does so by stimulating pressure receptors that transport signals to the vagus nerve.

Haphephobia is an anxiety disorder characterized by a fear of being touched. Other names for haphephobia include chiraptophobia, aphenphosmphobia, and thixophobia. A person with allodynia may also avoid being touched, but they do so because it causes them to feel pain rather than fear.

“People who have higher levels of social anxiety, in general, may be hesitant to engage in affectionate touches with others, including friends.” And the fear of someone ‘reaching out’—literally and figuratively—can make that discomfort even worse, she warns. There’s also a cultural component to being hug avoidant.

Basic warm touch calms cardiovascular stress. It activates the body’s vagus nerve, which is intimately involved with our compassionate response, and a simple touch can trigger release of oxytocin, aka “the love hormone.”

Rubbing your partner’s back, or massaging them, can signal to them that you’re there for them and that you love them. You can also rub their arm, their hand, or another part of the body. Just make sure you’re communicating with your partner and making sure they are comfortable with it.

1. Invest in a weighted blanket. Weighted blankets have small weights sewn into pockets across them. When you wrap it around you or lie beneath it, this can simulate feelings of being hugged or held, and research has shown it may help with stress relief and insomnia too.

Here is an overview of some of the ways you can show your quality time partner that you love them.

1. Make Eye Contact.
2. Use Active Listening Skills.
3. Set Limits on Technology.
4. Focus on Quality, Not Quantity.
5. Make a Plan.
6. Be Present and Available.
7. Stay in the Moment.
8. Get Creative.

According to Chapman, the five ways to express and experience love called “love languages” are:

• words of affirmation,
• quality time,
• receiving gifts,
• acts of service,
• physical touch.

“If you or your partner’s love language is gifts, that means you feel loved [or that you’re demonstrating love] with a tangible item,” says Williams. A person who feels loved through these items might cherish the gift, however small, more than another who speaks a different love language.

Quality time is giving someone your undivided attention. I mean sitting on the couch with the TV off, looking at each other and talking, and giving each other your undivided attention. For some people, quality time is their primary love language, and if you don’t give them quality time, they will not feel loved.
