What Triggers Happiness Hormones And How Can We Make The Most of Them In Everyday Life?

Updated: Nov 27, 2020

There are four main hormones (a type of chemical your body makes) that trigger feelings of happiness, and each chemical is connected to specific events or rewards. Understanding these chemicals and how they work can help you figure out even small ways to feel better at a stressful time.

Loretta Breuning, founder of the Inner Mammal Institute and author of Habits of a Happy Brain explains exactly how these happiness chemicals work.

Almost everything that makes you feel happy is linked to one of the four happiness hormones: dopamine, serotonin, endorphin and oxytocin. Here are some ways you can boost them:


The hormone dopamine is associated with motivation and reward. It's why you feel motivated when you set an exciting or important goal, and why it feels good to reach that goal. On the flip side, if you have low dopamine (which experts say can occur with depression), it can explain feelings of low motivation or loss of interest in something you used to enjoy.

"Approaching a reward triggers dopamine. When a lion approaches a gazelle, her dopamine surges and the energy she needs for the hunt is released. Your ancestors released dopamine when they found a water hole. The expectation of a reward triggers a good feeling in the mammal brain, and releases the energy you need to reach the reward." Breuning says.

How to boost it

Some not-so-healthy habits increase dopamine like drinking caffeine and eating sugar. But you can find ways to activate this hormone without turning to potentially unhealthy substances. 

"Embrace a new goal and take small steps toward it every day. Your brain will reward you with dopamine each time you take a step. The repetition will build and establish a new dopamine pathway" Breuning. 

You may already have goals set around your career, work or how much money you'd like to make. But don't forget personal goals. Committing to a rewarding hobby or sport can be just as gratifying as professional goals. Don't just set a few big goals that will take longer to complete, adopt shorter-term goals so you stay motivated.

"Set a short-run, long-run, and middle-term goal so you will always be approaching one when another is blocked. Focus on things you have control over and don't wait for others to set your goals for you," Breuning.

Other ways to boost Dopamine:

  • get enough sleep

  • sunlight

  • eat lots of protein

  • exercise


Serotonin is a neurotransmitter that plays a role in mood, but it also helps regulate other functions in your body like digestion, sleep and bone health. When it comes to happiness and how you feel every day, serotonin is important for reducing depression and regulating anxiety.

How to boost it

"Confidence triggers serotonin. Monkeys try to one-up each other because it stimulates their serotonin. People often do the same," Breuning.

You've probably never thought about confidence on a neurochemical level, but according to Breuning, if you don't prioritise confidence, your serotonin levels could take a hit. 

If you are trapped in a cycle of low self-esteem or have had others undermine your confidence, it can be hard to build it back up. It may sound strange, but don't ignore your need for respect and status.


"You can develop your belief in your own worth. If you focus on your losses you will depress your serotonin, even if you're a rock star or a CEO. You can build the habit of focusing on your wins. Your serotonin will suffer if you don't," Breuning. 

Besides focusing on what you've achieved in life, you can also build confidence in other ways. One way to do this is by working out or adopting a new exercise routine, which helps bolster your confidence when you stick to it over time and your physical strength.

Something else you can try is finding ways to get out of your comfort zone each day. Every day that you challenge yourself to adapt to something new, even if it feels uncomfortable at first, you build more confidence. 

Other ways to boost Serotonin:

  • essential oils

  • spending time in nature

  • eating Omega-3 fatty acids (which you find in cold-water fish like salmon)

  • reliving happy memories


Oxytocin is sometimes called the "love" hormone and is associated with how people bond and trust each other. Certain activities like kissing, hugging and having sex can trigger the release of oxytocin in the brain. 

It explains why you feel happy when you interact or cuddle with your pets. It's important in childbirth since oxytocin helps the mother's uterus contract to deliver the baby, and oxytocin plays a role in breastfeeding too. It also helps parents bond with a baby after birth.

How to boost it

You can boost oxytocin by being physically intimate with others. But besides the physical aspect, it's important to know that there's an emotional connection to how oxytocin is released.

"Social trust is what triggers oxytocin. If you hug someone you don't trust, it doesn't feel good. Trust comes first. You can build social trust by taking small positive steps toward people," Breuning. 

You can reach out to a friend or contact you'd like to get to know better. Send someone a thank you note or a card just to tell them you're thinking about them. "Take a small step toward someone each day, and they may reciprocate months later, but if you keep doing it you will build trust networks," Breuning. 

Other ways to boost Oxytocin:

  • active listening

  • giving a compliment

  • yoga

  • listening to music


Endorphins are notoriously linked with exercise, it's the phenomenon that explains the runner's high or post-workout endorphin "rush." They function as "natural painkillers" that help minimise pain and maximise pleasure. This chemical experience can explain why a runner may be able to push through a race with an injury that they don't notice until it's over.

"In the state of nature, it helps an injured animal escape from a predator. It helped our ancestors run for help when injured. Endorphins evolved for survival, not for partying. If you were high on endorphins all the time, you would touch hot stoves and walk on broken legs," Breuning explains.

How to boost it

Laughter is one way to boost endorphins naturally, so is eating dark chocolate, watching your favourite drama on Netflix, working out and meditating

Endorphins are released in response to pain, but that doesn't mean you should seek out ways to cause yourself harm (like overexercising or pushing yourself beyond your limits) just to feel good. 

"Inflicting harm on yourself to stimulate endorphins is a bad survival strategy. Fortunately, there are better ways: laughing and stretching. Both of these jiggle your innards in irregular ways, causing moderate wear and tear and moderate endorphin flow," she says.

Other ways to boost Endorphins:

  • meditate

  • eating chilli peppers

  • getting a massage
