You’ve probably heard that coloring reduces stress. It’s plastered across every coloring book cover and wellness article. But “coloring reduces anxiety” isn’t quite the whole story. We dug into the actual research, and it’s more nuanced — and more interesting — than the marketing suggests.
What the Studies Actually Show
The most-cited study on this is from Curry and Kasser (2005), which found that coloring a mandala for 20 minutes reduced anxiety more than coloring a blank page or a plaid design. Since then, several other studies have added context:
- A 2020 study in the International Journal of Art Therapy found that structured coloring (like mandalas) reduced anxiety more than free-form drawing, but both were better than doing nothing
- A 2018 study showed that 30 minutes of coloring significantly reduced cortisol levels (a stress hormone) in adults
- Research from 2021 found that the anxiety-reducing effects were strongest for people with moderate anxiety — those with clinical anxiety disorders saw much smaller benefits
- A fascinating 2019 study found that coloring worked as well as a brief mindfulness meditation session for reducing anxiety, but people actually enjoyed the coloring more
Why Coloring Works (The Science)
There are a few mechanisms at play:
Flow state activation: Coloring engages enough of your attention that your brain can’t simultaneously ruminate on anxious thoughts. It’s the same principle as knitting or playing an instrument — focused, repetitive activity quiets the default mode network, which is the brain region responsible for anxious overthinking.
Structure reduces decision fatigue: One reason coloring works better than free-form art for anxiety is that the boundaries are already drawn. You don’t have to decide what to create — just what color goes where. That’s cognitively easier, which matters when your brain is already overwhelmed.
Repetition and predictability: The repetitive motion of filling in small areas is soothing in the same way that rocking or walking is. Your brain likes predictable, rhythmic activities. It’s why mandalas specifically work well — they’re symmetrical and predictable, which feels safe to an anxious mind.
What Coloring Won’t Do
Let’s be honest about the limitations:
- Coloring is not therapy. It’s a coping tool, not a treatment.
- It won’t address the root causes of anxiety. If your anxiety comes from a specific situation, coloring gives you a break from it, but it doesn’t solve it.
- The effect is temporary. Studies show anxiety reduction during and shortly after coloring, but there’s no evidence the effects last beyond that session.
- It can backfire. If you’re a perfectionist, coloring can become another thing to stress about. (This is real — some people find the pressure to “stay in the lines” makes them more anxious.)
How to Get the Most Out of Coloring for Anxiety
Based on the research, here’s what actually works:
- Choose structured designs — Mandalas, geometric patterns, and symmetrical designs reduced anxiety more than free-form coloring
- Set a timer for 20-30 minutes — That’s the sweet spot in most studies. Less than 15 minutes doesn’t seem to be enough to enter that flow state
- Don’t overthink the colors — Pick what feels right, not what “should” go together. The benefit comes from the process, not the result
- Use physical books over apps — Studies that showed anxiety reduction used physical coloring, not digital. The tactile experience matters
- Lower the stakes — If you mess up, keep going. The whole point is to let go of perfection. (Harder than it sounds, we know.)
The Bottom Line
Coloring genuinely reduces anxiety — the research supports it. But it’s not magic. It’s a 20-30 minute activity that gives your brain a break from anxious thought loops. Think of it like a walk for your mind: helpful, accessible, and free of side effects, but not a substitute for professional help when you need it.
If you want to try it, grab a mandala coloring book, set a timer for 20 minutes, and just start. Don’t pick the “right” colors. Don’t aim for a frameable result. Just fill in the spaces and let your brain rest.
