Do affirmations work? What the research actually says

Do affirmations work? They can, a little, when the lines feel believable to you. Kind, realistic self-talk seems to steady people. Big, glowing claims you don't believe can leave some people feeling worse.

We make an affirmations app, so you might expect us to promise wonders. We'd rather be straight with you. Below is what the studies actually found, where they stop, and how to use affirmations so they have a fair chance of helping.

What counts as an affirmation?

An affirmation is a short, kind sentence you say or read to yourself on purpose, like "I can handle today" or "I'm allowed to rest". It's self-talk you choose, instead of the automatic kind, which is often much harsher.

So, do affirmations work? What the studies found

Three lines of research are worth knowing about. They point in slightly different directions, which is exactly why the wording of your lines matters.

Writing about what you value seems to help

Psychologists have studied "self-affirmation" for decades. In these studies, people usually spend a few minutes writing about a value that matters to them, such as family, kindness or creativity, before facing something stressful. A 2014 review by Geoffrey Cohen and David Sherman links this with people feeling less defensive and less rattled, with some benefits in school, health and relationship studies. The effects are usually modest and they vary from study to study. Still, the core idea is useful: reminding yourself what you care about can steady you.

Can affirmations backfire?

Sometimes, yes. In a 2009 study, Joanne Wood and her colleagues asked people to repeat "I'm a lovable person". People with low self-esteem who repeated it ended up feeling worse than people who didn't repeat it at all. People with high self-esteem felt a bit better, but only slightly.

One likely reason: a line that clashes hard with how you see yourself can remind you of every reason you disagree with it. That doesn't mean affirmations are useless when you're struggling. It means the wording matters a lot, and our guide to writing affirmations that feel true is built around that.

Why "you" can work better than "I"

A 2014 study led by Ethan Kross looked at how people talk to themselves before stressful moments, like giving a short speech or meeting someone new. People who used their own name or "you" instead of "I" showed less distress, did better according to outside judges, and dwelt on it less afterwards. A little distance, as if a friend were talking, seems to make self-talk calmer.

Does saying affirmations out loud help?

It may help them stick. Memory researchers call it the production effect: words you say out loud tend to be remembered better than words you read silently, probably because speaking makes them stand out.

A 2017 study by Noah Forrin and Colin MacLeod compared four ways of learning: reading silently, hearing someone else read, hearing a recording of yourself, and reading aloud yourself. Reading aloud yourself came out on top. So hearing a line read to you is nice, but saying it back in your own voice is the part that seems to count.

One honest caveat. These studies used word lists and study material, not affirmations. So "say it aloud in the morning and it's more likely to come back to you in a hard afternoon" is a sensible hint, not a proven fact.

How to use affirmations so they actually help

• Choose lines you can nearly believe. Aim for "this could be true", not "this is obviously not me".
• Lean on bridge words like "I'm learning to", "I'm allowed to" and "I can". They're easier to say honestly than big declarations.
• Anchor a line in something you value. "I care about being fair, and I was fair today" rests on something real. Our confidence affirmations for work lean on this a lot.
• Talk to yourself the way a kind friend would, using "you" or your own name.
• Say it aloud, slowly, a couple of times. Then get on with your day.
• Don't use them to shout down real feelings. "This is hard, and I can take one step" is usually kinder than "Everything is fine". Our affirmations for hard days are written that way.

If you'd like this to become a small daily thing rather than a one-off, there's a whole guide on making affirmations a daily habit. Or just try today's line from our free kind line of the day.

What affirmations can't do

They can't change hard circumstances. They can't stand in for sleep, food, rest or people who care about you. And they can't treat depression, anxiety or any other health condition.

They're one small, gentle tool. Used alongside everything else that helps you, they can make the voice in your head a bit kinder, and that's the honest limit.

Where Kind to Me fits

We built Kind to Me around the parts that hold up. It shows one line at a time rather than a wall of them, and it reads lines aloud if you want to hear them. Its Say It With Me practice walks you through a few lines to repeat out loud, which is the part the memory research favours. You can also mark a line "More like this" or "Less like this", and the app leans towards the kind of lines that suit you.
