Welcome to the health and happiness blog. This week’s topic concerns a hormone that not many people know about, called oxytocin. 

Oxytocin’s role in the body

Oxytocin was initial considered to be a hormone mostly with a pivotal role in pregnancy. It starts the final stages of pregnancy and helps prepare for and start the delivery phase. 


But although that’s kind of where research interest in it began, it was soon discovered that it has a much bigger role in both men and women, and it began to be referred to as the love hormone or the bonding hormone. Not only is that good for your mental wellbeing, this hormone also impacts your physical health too. 

What affects oxytocin levels

There are many things that we can do to improve and increase the amount of oxytocin in our body (without having to get pregnant!) Doing anything that connects us to somebody else will increase our oxytocin levels, that includes:

  • talking to somebody
  • walking with somebody
  • singing with somebody

and the ‘with somebody’ is really important. 

Oxytocin is increased when we do activities together. Although singing and dancing on their own will increase oxytocin, doing it with others increases it further.

 Hugging, which of course tends to be an activity involving somebody else, connecting, touching people and making eye contact with others also increases oxytocin.

So combining these things, looking into somebody’s eyes when you speak to them or hold their hands that will increase oxytocin even more. This building a sense of connection is why things like walking together rather than just walking on your own Increases your oxytocin levels.

Health effects

Oxytocin levels are important for a range of body systems and has an important role in undoing the harms of stress, as a result it has been found to affect cardiovascular health, gut health, memory and learning, building trust, being kind, developing relationships. neuroplasticity and mental health.(Argiolas & Gessa, 1991; Froemke & Young, 2021; Kosfeld et al., 2005; Uvnas-Moberg & Petersson, 2005; Zak et al., 2007)

Increasing your levels

Based on this, think about what you can do to increase your oxytocin levels.

How can you connect to others more? This is going to be particularly important currently, as I’m writing this just coming out of lockdown from the pandemic, where there’s been a lot of people who’ve not been able to connect to others. The interesting thing, of course, is that oxytocin is still increased when we connect on things like videos or zoom or Twitter, even. As long as it’s a positive conversation, you’ll get a degree of increase in oxytocin, it’s not as strong as if you’re directly with someone. 

Do something that’s kind for another person, spend time with them, Virginia Satir, the famous family therapist said

We need 4 hugs a day for survival. We need 8 hugs a day for maintenance. We need 12 hugs a day for growth.

And of course, if you do that with somebody else, you’ll be increasing their oxytocin too. 

So it’s good for us and it’s good for them.

Let me know how you get on with checking in with your oxytocin levels. See you on the next one.
