The Science Behind Happiness and How to Achieve It

25 February 2025

Happiness. It’s something we all crave, right? But have you ever stopped to wonder what happiness actually is? Why do some people seem naturally happier than others, and more importantly, is there a way to scientifically crack the code to find true, lasting happiness?

Well, you’re in luck! In this article, we’re going to dive into the fascinating science behind happiness and, more importantly, how you can achieve it. Spoiler alert: it’s not just about chasing pleasure or avoiding pain. Ready? Let’s get started!

What is Happiness Anyway?

Before we get into the nitty-gritty science, let's first define happiness. It’s a term we toss around so casually, but what does it really mean?

Psychologists typically break happiness down into two main types:

1. Hedonic Happiness: This is all about experiencing pleasure and avoiding pain. Think of it like eating your favorite dessert or binge-watching a Netflix series. It feels good in the moment but doesn’t necessarily lead to long-term fulfillment.

2. Eudaimonic Happiness: This is the deeper, more meaningful form of happiness. It’s about living in alignment with your values, having purpose, and contributing to something bigger than yourself. It’s the kind of happiness that sticks around long after the Netflix binge is over.

Both types of happiness play a role in our lives, but if you’re looking for long-lasting joy, eudaimonic happiness is where the magic happens.

The Science Behind Happiness: Chemicals in Your Brain

Let’s get geeky for a minute. When we talk about happiness, we can’t ignore the chemicals in our brains. These little guys are responsible for the highs, the lows, and everything in between.

The "Happy Chemicals"

There are four main chemicals that are often referred to as the “happiness quartet”:

1. Dopamine: Known as the "feel-good" chemical, dopamine is linked to pleasure and reward. When you accomplish a goal, hit a milestone, or even just check something off your to-do list, dopamine kicks in and gives you that rush of satisfaction.

2. Serotonin: This one plays a key role in mood stabilization. Low serotonin levels are linked to depression and anxiety, while higher levels are associated with feelings of well-being and happiness.

3. Oxytocin: Often called the "love hormone," oxytocin is responsible for feelings of trust, bonding, and intimacy. It’s released during moments of connection, like hugging a loved one or even petting your dog.

4. Endorphins: These are the body’s natural painkillers. They’re released during exercise, laughter, or even when you eat spicy food. Endorphins give you that "runner’s high" and help to mask pain, both physical and emotional.

The balance of these chemicals plays a huge role in how happy we feel. But here’s something interesting: our brains are wired to crave novelty and rewards, which means we can’t rely on just dopamine hits to keep us happy. That’s why long-term happiness requires a bit more than just chasing fleeting pleasures.

Let’s dig deeper into how we can achieve that.

The Happiness Set Point: Are We Doomed By Genetics?

Ever notice how some people are just naturally more cheerful while others seem perpetually grumpy, even if they win the lottery? That’s not just in your head; it’s actually backed by science.

The 50-40-10 Rule

Psychologists have found that about 50% of our happiness is determined by genetics—this is often referred to as the "happiness set point." It’s like a baseline level of happiness that we tend to return to, whether good or bad things happen.

But here’s the good news: 40% of our happiness is within our control, determined by our thoughts, behaviors, and actions. The remaining 10% is influenced by external circumstances like income, relationships, and health.

So while genetics play a role, the choices you make every day have the biggest impact on your happiness. That’s empowering, right?

How to Achieve Happiness: Practical Steps

Okay, so now that we’ve covered the science, let’s talk action. How do we take control of that 40% and boost our happiness levels?

1. Cultivate Gratitude

This might sound cliché, but practicing gratitude really works. When you focus on what’s going well in your life, rather than what’s lacking, you shift your mindset. It’s like putting on a pair of rose-colored glasses that help you see the beauty in everyday moments.

Studies show that keeping a gratitude journal can significantly boost your happiness levels. Try writing down three things you’re grateful for every day. It doesn’t have to be big—something as simple as “I had a delicious cup of coffee this morning” counts!

2. Invest in Relationships

Remember oxytocin, the “love hormone”? It thrives on human connection. Building strong, meaningful relationships is one of the most powerful ways to increase your happiness. And I’m not just talking about romantic relationships—friendships, family, and community connections all count.

Make time for the people who matter. Call an old friend, have dinner with your family, or even join a club or group where you can meet new people. Strong social connections are consistently linked to higher levels of happiness.

3. Engage in Acts of Kindness

Here’s a fun fact: helping others actually makes you happier than helping yourself. It’s true! When you engage in acts of kindness, your brain releases a flood of feel-good chemicals like dopamine and oxytocin.

Try doing something small for someone else today—whether it’s complimenting a colleague, buying coffee for a stranger, or donating to a charity. Not only will you brighten their day, but you’ll get a happiness boost too. It’s a win-win!

4. Find Flow

Ever been so absorbed in an activity that you lose track of time? That’s called “flow,” and it’s a key ingredient for happiness.

Flow happens when you’re fully engaged in something challenging yet rewarding. It could be anything from painting, writing, coding, or even playing a sport. The key is to find activities that push you just outside your comfort zone but are still enjoyable.

If you haven’t yet found your flow activity, try experimenting with different hobbies until something clicks.

5. Exercise Regularly

We’ve all heard it: exercise is good for you. But did you know it’s also one of the quickest ways to boost your mood?

Exercise releases endorphins, those natural painkillers that make you feel good. Plus, it reduces stress and anxiety, boosts self-esteem, and improves sleep—all of which contribute to higher levels of happiness.

You don’t have to run a marathon to get the benefits. Even a 20-minute walk in nature can do wonders for your mood. The key is to find an activity you enjoy.

6. Practice Mindfulness and Meditation

Mindfulness is about living in the present moment and fully experiencing it without judgment. When we’re constantly worrying about the future or dwelling on the past, it’s hard to be happy.

Meditation is one way to cultivate mindfulness, and research shows that regular meditation can rewire your brain to be more focused, calm, and happy. But you don’t have to be a monk to get started! Even just 5-10 minutes of meditation a day can make a noticeable difference.

7. Set Meaningful Goals

Remember eudaimonic happiness? It’s all about living with purpose. Setting meaningful goals gives your life direction and gives you that sense of accomplishment when you achieve them.

But here’s the catch: the pursuit of the goal is often more fulfilling than actually reaching it. So don’t just focus on the end result—enjoy the journey. Whether it’s learning a new skill, volunteering for a cause, or improving your health, set goals that align with your values, and you’ll find happiness along the way.

The Role of Perspective: Can Happiness Be a Choice?

Now, here’s the million-dollar question: Can you choose to be happy?

While you can’t control everything that happens to you, you can control how you respond to it. Happiness isn’t about avoiding challenges or pretending everything is perfect. It’s about cultivating a mindset that allows you to find joy even in difficult moments.

Think of happiness like a muscle. The more you work on it—through gratitude, mindfulness, and positive connections—the stronger it becomes.

Conclusion: The Journey to Happiness

So, there you have it—the science behind happiness and how to achieve it. It’s not about chasing quick dopamine hits or avoiding life’s challenges. Happiness is a combination of brain chemistry, genetics, and, most importantly, the daily choices we make.

Remember, happiness is a journey, not a destination. It’s something you can actively cultivate through gratitude, relationships, kindness, and personal growth.

And the best part? The more you focus on building habits that promote happiness, the easier it becomes to sustain. So why not start today?
