What is a hug without the squeeze? In America, they’ll tell you that’s like apple pie without the cheese. We prefer ice cream with our pie but we definitely like our hugs with the right amount of squeeze. Turns out, however, that hugging has been studied fairly carefully in the research!

Hugging is Old School

The word "hug" originates from the Saxon word "hog" meaning "to be tender to" and the old Norse word  "höggva", meaning "to catch or seize[i]". Hugging has been around at least since Biblical times, for example brothers Jacob and Esau hugging when reunited in the book of Genesis. It is not just a modern phenomenon but something that is a long-standing part of human history.

We’re going to have some fun and some research with this subject today — let’s look at some fun facts related to hugging.

Fun Facts

Tree Hugging

Turns out there are some cultures who believe that hugging trees can help restore your body and mind. In remote areas of Finland, hugging snow-covered trees is used as a kind of meditation or spiritual practice to connect with nature. This is now becoming a tourist trade where people travel into the wilderness to hug trees. Not my idea of a romantic getaway, but whatever works for you.

National Hugging Day

January 21st is National Hugging day in the US and other countries, founded in 1986 to promote healthy expression of emotion.

I’m going to have to mark that one down on my calendar.

Self Hug Machines

Got no-one to hug you? Never fear — science has your back. The "Sense Roid" is a recently invented machine that recreates the sensation of being hugged using a mannequin with pressure receptors and a jacket with artificial muscles that constrict to give the sensation of being hugged. The idea behind it was that hugs are better when you are hugging someone you are intimate with, and who are you more intimate with than yourself? So now you can get the benefits of hugging without needing other people. Maybe.

Should You Hug Dogs?

Good question. Research shows that while many pet owners like hugging their pets, most animals don't appreciate it. For example 8 out of 10 dogs show signs of distress when hugged, as it restrains them and prevents them from being able to get away. I guarantee that every dog owner reading this is now thinking “well my dog is obviously one of the 2 out of 10 who loves hugs!”

Cultural Rules

Hugging as a greeting varies a lot between cultures. In some places a hug with one or more kisses is the normal greeting for friends and acquaintance, in some countries any kind of physical touch would be an offence. In some countries such as France the rules on an appropriate greeting even vary between cities. Some examples (from most to least contact):

Paris: Hug and four kisses

Netherlands, Switzerland, Brittany: hug and three kisses

Spain, Austria: hug and two kisses

Belgium: one kiss

Germany, Italy, UK, America: hug with close friends/family only

Thailand, Japan: no physical contact. Just a bow!

Got all that? Good. Don’t want to look like an idiot going in for too many kisses. Ok, let’s move on to the actual science of what makes hugging great.

The Science of Hugging

Hugging Releases Oxytocin

Oxytocin is the brain's "love hormone" which creates attachment between spouses and increases feelings of affection, empathy and bonding. Oxytocin is released through hugging[ii]. Meaning that hugs don’t just feel great, they work to strengthen the bond between you and your spouse.

Hugging Activates Pressure Receptors

There are pressure receptors all over the body which respond to physical touch. When those receptors are gently activated by hugging, they prompt chemical changes in the brain such as reducing the stress hormone cortisol increasing endorphins and serotinin, as well as lowering heart rate and blood pressure[iii].

Very cool.

Hugging Promotes Support and Belonging

As well as these chemical changes there are more conscious psychologica...
