I love it when my favorite pastimes are proven to be highly beneficial.

Kissing has long been a means of showing affection, boosting confidence, connecting with a loved one and igniting your inner fire.

Most people love kissing… especially when they are kissing the right person! But did you know that there is actually a long list of health benefits that comes along with a good kiss?

As if the happy hormone rush wasn’t enough to keep us locking lips…

Here are 10 benefits of kissing you probably didn’t know about:

#1 Pain Relief

The hormones released during kissing act as natural pain relievers. Endorphins, one of these hormones, is said to be more powerful than any analgesic. Kissing also dilates the blood vessels, increasing blood flow and potentially soothing migraines and headaches.

#2 Lowers Blood Pressure

According to Dr. Mercola, kissing actually helps your blood vessels to dilate (open up) and may have a beneficial effect on blood pressure.

#3 Boosts Heart Health

In a study done by the University of Paisley, researchers found that men who kissed and made love regularly (at least twice a week) were 45% less likely to develop heart disease in their lifetime.

#4 Boosts Immune System

Some scientists believe that kissing evolved as a way to pass germs so that overall cultural immunity was boosted.

Studies show that kissing boosts activity of the immune system and may help to protect against specific viruses like the cytomegalovirus.

However, according to Dr. Hendrie of the University of Leeds, you receive the most immune-boosting benefits when you stick with the same kissing partner for at least 6 months or more.

#5 Improves Oral Health

Kissing naturally causes an increase in saliva production. There are enzymes in your saliva that fight cavity and plaque-causing bacteria.

#6 Reduces Stress

A study at Northwestern University Feinberg School of Medicine involving 2,000 couples found that those who kiss spontaneously throughout the day are less likely to suffer from stress and depression. This is due to the stress-relieving endorphins that are released during an enjoyable kiss.  

#7 Relieves Symptoms Of PMS

The natural pain-relieving endorphins released during a good kiss may also benefit those suffering from severe symptoms of PMS. Kissing helps to release tension in the down-under and increase blood flow – which may help to sooth discomfort during your “shark week.”

#8 Improves Mood

Your lips contain a ton of sensory neurons when compared to other surfaces in your body. These are stimulated by kissing and trigger a release of various happy hormones like oxytocin, serotonin and dopamine. It also triggers sebum, an oil believed to play a role in bonding.

#9 Strengthens Facial Muscles

There are 43 muscles in your face, 34 of which are used during kissing. A vigorous kissing session can help to strengthen and tone these muscles in your face and also your neck!

#10 Burn Calories

Although kissing won’t replace your weight-training session, a passionate kiss has potential to burn around 16 calories!

Ready to go wrap your arms around your lover’s neck and give them a good kiss?

What Our Clients Say*

During my FitLife transformation, I lost 70 pounds! That's why I signed up for the protocol, but the most exciting result is that I found ME in the process. I had been hiding under a pile of pounds, self-doubt, and grief! FitLife changed my life and I knew I had to share it with others.

-Lynne, Longwood FL

I started with Fitlife back in 2011-2012…I wrote into Fitlife asking for an extreme amount of help. I was 300 pounds, with high cholesterol, and Drew helped me transform my life. I lost over 130 pounds and I no longer have high cholesterol. Not only did I lose weight, so did my husband, who lost over 70 pounds!
