The Pain and Pleasure Principle: Why Your Brain Chooses Pleasure Over Pain (and How Your Words Shape It)

The pain and pleasure principle is simple: your brain moves you away from what it links with pain and toward what it links with pleasure, because its number one job is keeping you alive. The tricky part is that your brain doesn't only learn "pain" from your body. It also learns it from your emotions and from the words you use, which is why something that isn't dangerous at all can start to feel like a threat.

I'm Paola Mendez, a certified RTT (Rapid Transformational Therapy) hypnotherapist in Coral Gables and the founder of Mochi Zen. In my sessions, I see this principle running quietly behind so many "why do I keep doing this?" questions. Here's how it works, why your brain chooses pleasure over pain even when you know better, and how your words can make things feel more painful than they are.

What Is the Pain and Pleasure Principle?

The pain and pleasure principle is the idea that most of what we do comes down to two forces: moving away from pain and moving toward pleasure. Psychology has talked about this for a long time. Sigmund Freud called the pleasure-seeking side the "pleasure principle," the instinct to seek pleasure and avoid pain.

Here's how I explain it to clients. Pain, to your brain, means danger. It means something might be happening to your body that could stop you from surviving. So your brain does two things on repeat: it pushes you away from pain, and it pulls you toward pleasure, because pleasure signals "this is safe, do more of this."

That system is brilliant when the danger is real. The problem starts when your brain files something under "pain" that isn't actually dangerous.

Why Does Your Brain Choose Pleasure Over Pain?

Because your brain cares about survival first and your goals second. When you're deciding between the couch and the gym, or between speaking up and staying quiet, the logical part of you might know what's best. But the part of your mind that runs on autopilot is asking a much older question: "Which one feels safer right now?"

And here's the key: your brain doesn't wait for something to actually hurt you. It reacts to what it has learned to expect will hurt. If a situation has been linked with embarrassment, stress or exhaustion, your brain treats it as something to escape. Not because you're weak or lazy, but because your mind is doing exactly what it was built to do: protect you.

What Are the Parts of Pain, According to Psychology?

Pain isn't just one thing, and even the official definition says so. The International Association for the Study of Pain (IASP) defines pain as "an unpleasant sensory and emotional experience" linked with actual or potential tissue damage, and its 2020 revision adds that pain is always influenced by biological, psychological and social factors, and that pain and the nerve signals for damage are not the same thing.

Back in 1968, pain researchers Ronald Melzack and Kenneth Casey proposed that pain has several dimensions, an idea Casey later revisited and refined. In Melzack's own later description, those are the sensory-discriminative, affective-motivational and evaluative-cognitive dimensions. Add the basic nerve signal underneath them, and in plain language pain has these layers:

• The nerve signal. Your nerves pick up a signal and your body reacts, sometimes before you even think. That's why you pull your hand off a hot stove or flinch from a needle without deciding to.
• The "what and where" part (sensory). How strong is it? Where is it? Is it sharp, burning, aching?
• The emotional part (affective). How much does this pain upset me? How much do I want it to stop?
• The meaning part (evaluative). What do I think this pain says about me, my safety or my future?

Those last two are where things get interesting. We can attach strong emotion and meaning to things that aren't physically painful at all: a job, a stage, a gym, a conversation. And once something carries that emotional weight, your brain starts pushing you away from it, because it thinks it's protecting your survival.

How Do Words Affect Your Subconscious Mind?

Think about the things we say without a second thought:

• "This job is killing me."
• "I'd rather die than speak in front of people."

In my practice, I've come to believe that the subconscious mind doesn't have a sense of humor and doesn't understand sarcasm. It takes what you say at face value. So when you say "this job is killing me" every day, your mind hears: this job is a threat to my survival, and I need to get you away from it.

The mind-body link here is real. Stress is one of the most commonly reported migraine triggers; the American Migraine Foundation says it's a trigger for almost 70% of people with migraine. And Harvard Health explains that the brain has a direct effect on the stomach and intestines, and that emotions like anxiety can trigger symptoms in the gut.

Here's what that can look like with my clients. Someone who tells themselves their job is killing them starts waking up with headaches on workday mornings. Someone who was laughed at by classmates in school, and decided "I'd rather die than do that again," now gets an urgent upset stomach every time they have to get on stage. I see these patterns again and again. Not every headache or stomach problem comes from words, but when we trace the pattern back, there's very often a moment where the mind decided "this is dangerous" and has been protecting the person ever since.

That's why I tell everyone: be very careful with the words you say. Use them with intention, and say exactly what you actually mean.

Why Does Food Feel Like Comfort and Exercise Feel Like Punishment?

The pain and pleasure principle shows up most clearly at 9pm. If your brain links food with comfort and exercise with punishment, guess which one wins? This isn't a willpower problem. Those links were learned, which means they can be relearned.

I've written about each piece of this in more depth. If the workout never happens, start with why you can't motivate yourself to exercise. If you keep "trying harder" and it keeps not working, read why willpower doesn't work for weight loss. And if food has become your main source of comfort, how to stop emotional eating goes deeper into where that comes from.

How Do You Change What Your Brain Links to Pain?

The good news is that the same system that learned these links can learn new ones. Here's where I'd start.

1. Catch your phrases. For one week, notice the dramatic things you say about your job, your body, your relationships or your goals. Write them down.
2. Say what you actually mean. "This job is killing me" becomes "This job is stretching me right now, and I'm deciding what I need." "I'd rather die than present" becomes "Presenting makes me nervous, and I can learn to handle nerves."
3. Attach pleasure to what you want more of. Your brain moves toward what feels good. Pair the thing you avoid with something you enjoy, and talk about it in terms of what it gives you, not what it costs you.
4. Go to the root with hypnotherapy. In RTT sessions, we use a relaxed, focused state to find where an association started, like the classroom moment or the first time exercise felt like punishment, and rewire it. Then repetition helps the new meaning become the automatic one.

One important note: if you're getting regular migraines, stomach problems or any new physical symptom, please see a doctor first to rule out a medical cause. Hypnotherapy works best alongside good medical care, not instead of it.

Frequently Asked Questions

What is the pain and pleasure principle in psychology?

The pain and pleasure principle is the idea that people are driven to move away from pain and toward pleasure. Freud called the pleasure-seeking side the "pleasure principle." Because your brain's top priority is survival, it treats anything it links with pain as a threat and anything it links with pleasure as safe.

Why does my brain choose pleasure over pain even when I know better?

Because the automatic part of your mind is focused on what feels safe right now, not on your long-term goals. If something has been linked with stress, embarrassment or discomfort, your brain will steer you away from it, even when the logical part of you knows it's good for you.

How do words affect your subconscious mind?

In my experience as a hypnotherapist, the subconscious takes words at face value and doesn't understand sarcasm. Saying "this job is killing me" over and over can teach your mind that your job is a threat. Choosing words that say exactly what you mean helps your mind stop treating everyday things as dangerous.

Can you change what your brain associates with pain?

Yes. Associations are learned, so they can be relearned. Noticing and changing the words you use is a good start, and RTT hypnotherapy works on finding where an association began and replacing it with a new meaning that you repeat until it feels automatic.
