Does the timber species affect biophilic response?

Yes, research indicates that lighter-coloured timbers with visible grain patterns (such as spruce, birch, and ash) produce stronger relaxation responses than very dark timbers or timbers with minimal grain. However, cultural context matters — Japanese studies show strong positive responses to hinoki cypress, while Scandinavian studies favour pine and spruce.

However, cultural context matters — Japanese studies show strong positive responses to hinoki cypress, while Scandinavian studies favour pine and spruce. The most consistent finding is that natural, uncoated timber with visible grain produces stronger biophilic responses than painted, stained, or heavily lacquered timber regardless of species.
