Study Shows You Can Shower Away Stress

Plenty of people would tell you one thing they do after a really stressful day is to either hop in a hot shower or to climb into a warm bath. The connection between getting clean and lowering your anxiety has been known but not really understood.

A recent study took a look at it and they found that there’s biological effects and measurable differences in the anxiety of people when cleaning oneself is involved. Published in Social Psychological and Personality Science, the new findings provide some of the first scientific evidence that cleaning oneself is related to reductions in anxiety.

Study author Spike W. S. Lee, an associate professor of management and psychology at the University of Toronto and director of the Mind and Body Lab, and his research team recruited 1,150 adults via Prolific and had them watch a brief video clip of a terrified woman standing at the edge of a bungee jump station. The video had previously been shown to induce anxiety, tension, and uneasiness in viewers. The participants were then randomly assigned to watch a video showing how to properly wash one’s hands, a video on how to draw a circle, or a video on how to peel an egg.

Those who watched the handwashing video tended to subsequently report lower levels of anxiety compared to those who watched the two other videos. The researchers then replicated the findings in a second experiment that included 1,377 individuals recruited from Amazon’s Mechanical Turk crowdsourcing platform. But the researchers noted that the handwashing video involved the element of self-touch. “Because touch is soothing and calming, what appeared to be cleaning effects might have been touch effects instead,” they noted.

To account for this potential confound, the researchers conducted a third experiment with 465 participants in which the three videos were replaced with mental imagery tasks. After watching the anxiety-inducing video, the participants were randomly assigned to either “imagine you are getting your arms, face, neck, and hair thoroughly cleansed with water,” “imagine you are touching your arms, face, neck, and hair to thoroughly feel yourself,” or were not instructed to imagine anything.

In line with their hypothesis, Lee and his colleagues found that anxiety levels tended to be lower among those who imagined cleaning compared to those who imagined touch and those in the control condition.

“When we engage in cleaning behavior, it involves separating residues from our body (e.g., washing dirt off your hands),” Lee told PsyPost. “This basic, physical experience of separating residues from our body can trigger a more psychological form of separation, namely, separating the residual influence of past experiences from the present (e.g., wiping the slate clean). If the past experiences were stressful, then psychologically separating them from your present would reduce your stress.”

So your hot shower or your leisurely bath? Those work. And you can tell the family that it’s for your mental health and based in science!

However, Lee noted that the study — like all research — includes some caveats. “While we demonstrated the phenomenon in samples with a wide age range, they are drawn from Western populations only,” he explained. “Whether the phenomenon generalizes to other cultures remains to be seen. Also, our findings invite future research to investigate what other protective effects may result from cleaning behavior in daily life.”
