Can nature-themed art influence short-term brain responses?

A virtual-room study examines EEG, blood pressure and perceived restoration after brief exposure.

An image of nature is not the same exposure as a garden. Chen and colleagues tested a nature-themed artwork alongside other indoor scenes.

The study

30 people were recruited and 23 were analyzed. On separate days, after stress and fatigue, they viewed five one-minute versions of the same furnished virtual office: a blank foreground, an architectural window view, nature art, a natural window view and a living wall. Scene order was balanced.

The findings

Compared with the blank foreground and architectural window view, nature art was associated with lower systolic blood pressure, higher perceived restorativeness and greater alpha power in frontal, central and parietal EEG regions. Heart rate and diastolic blood pressure showed no significant differences. Nonsignificant comparisons with the natural view and living wall do not establish equivalence.

Architectural interpretation

Nature imagery is worth investigating where direct outdoor contact is limited. The study does not show that pictures can replace access to nature.

Limits and conclusion

The sample was small, exposure lasted one minute and only one artwork was tested. Multiple comparisons and the laboratory setting limit generalization. EEG differences do not demonstrate new synapses, lasting plasticity or clinical improvement.
