ColorNestResearch consistently shows that coloring reduces anxiety in adults — but so does free drawing, and neither is clearly superior to the other. The benefit appears to come from the focused, repetitive nature of any structured creative activity, not from coloring specifically. That said, the anxiety reduction is real and measurable, and coloring has practical advantages as a daily stress management tool.
What the research actually shows
Three studies are worth knowing well:
1. A 2020 SAGE Journals randomized study (n = 60) compared anxiety reduction from coloring a design, drawing a design, and drawing to express emotions after an anxiety induction. All three activities reduced anxiety significantly after the session. Heart rate decreased and respiratory sinus arrhythmia increased across all conditions — physiological markers of reduced stress. There were no significant differences between groups. The researchers concluded that “drawing, regardless of emotion regulation strategy used, reduces anxiety” (doi: 10.1177/0276237420923290).
2. A 2022 meta-analysis published in a Swedish academic repository analyzed eight studies (578 participants total) comparing mandala coloring to free drawing for state anxiety reduction. The pooled effect size (Hedges’ g = 0.16) was not statistically significant (p = 0.12), meaning mandala coloring was not found to reduce anxiety more than free drawing. The researchers noted evidence of publication bias toward smaller, positive-result studies. Importantly, both mandala coloring and free drawing were anxiety-relieving — the finding is that one is not superior to the other (diva2:1650566).
3. A randomized controlled trial published in Academic Emergency Medicine tested adult coloring books against a placebo in 53 emergency department patients with significant anxiety (Hospital Anxiety and Depression Scale score of 7 or above). After 2 hours, the coloring group showed a mean HADS-A decrease of 3.7 points (95% CI: 2.4–5.1, p less than 0.001) versus 0.3 points in the placebo group (95% CI: −0.6–1.2, p = 0.51). The adjusted mean difference between groups was 3.2 points (p less than 0.001). The researchers concluded that adult coloring books are a reasonable strategy for reducing anxiety in a clinical setting (doi: 10.1111/acem.13838).
The honest summary
- Coloring reduces anxiety. So does free drawing. Both are anxiety-relieving activities.
- Mandalas are not measurably more effective than other coloring pages.
- The effect size in the ED study was clinically meaningful (3.2-point HADS-A reduction).
- The mechanism is likely focused attention displacing worried thinking — sometimes called “cognitive easing” or “active distraction.”
- More high-quality RCTs are needed before strong clinical recommendations can be made. The existing studies use convenience samples, are mostly female, and have small sizes.
Why coloring may work for stress
Attention displacement: Coloring requires you to make continuous small decisions — where to place the next stroke, which color to use, whether the shade is right. This specific, concrete engagement leaves little mental bandwidth for the rumination that sustains anxiety.
Repetitive motor action: Like knitting or other crafts, coloring involves repeated physical motion with a predictable outcome. Repetitive motor actions are associated with a calming effect on the autonomic nervous system in occupational therapy practice.
Achievable mastery: Completing a coloring page gives a tangible sense of accomplishment with a low skill floor. Unlike many stress-relief activities that require learning (meditation, yoga), coloring produces a visible result from the first session, which sustains engagement.
Low social demand: Coloring can be done alone, at any time, without equipment, performance pressure, or social interaction — making it accessible during high-anxiety periods when social activities feel overwhelming.
Practical guidance for using coloring for stress relief
Choose the right design: Medium-complexity designs (sections roughly 0.5–1.5 inches wide) are best for stress relief. Very simple pages do not engage attention enough. Very intricate pages can increase frustration.
Set aside interruption-free time: even 15–20 minutes of uninterrupted coloring produces a measurable mental shift for most adults. Put the phone in another room.
Choose colors intuitively rather than planning analytically: the planning step can itself become stressful. Let color choices be spontaneous.
Have a regular time slot: making coloring a predictable part of a daily or weekly routine — like 20 minutes before bed — builds it as a reliable stress management tool rather than something you only do when you remember.
Pair with other calming activities: coloring while listening to music, a podcast, or an audiobook extends the session naturally and adds a second layer of positive engagement.
Best page types for relaxation
| Page type | Why it works for stress |
|---|---|
| Mandalas | Repetitive, symmetric structure guides attention clearly |
| Florals and botanicals | Organic shapes allow interpretive coloring choices |
| Geometric patterns | Clear structure, no ambiguity about where colors go |
| Landscapes | Larger sections fill quickly; rewarding progress |
| Fantasy and abstract | Freedom from “correct” colors reduces performance pressure |

What coloring is not
A few claims circulate that go beyond what the evidence supports:
“Coloring is as effective as meditation.” Not established. Clinical mindfulness meditation has a large body of randomized evidence behind it. Coloring has a handful of small studies, some positive, some null. The mechanisms may overlap, but the evidence base does not.
“Adult coloring books cure anxiety disorders.” No study makes this claim. The ED trial (Marchesi et al.) showed benefit for situational anxiety in a waiting-room context, not for anxiety disorders. Coloring is a coping strategy, not a treatment.
“Mandala patterns are uniquely calming.” The meta-analysis found no significant difference between mandala and free drawing. Both work. The structure of the activity matters more than the specific pattern.
“You need expensive supplies to benefit.” No evidence supports this. The ED trial used standard adult coloring books. A printed page from ColorNest and a basic crayon set produce the same opportunity for focused engagement as a premium product.
The practical upshot: coloring is a genuinely useful, low-cost, no-barrier relaxation activity. It does not require expensive supplies, specialized knowledge, or prior art skill. The primary risk of over-claiming is that people become disappointed when it does not replace more intensive stress management or clinical treatment. Used as one tool among several, it is worth adding to a regular self-care routine.
