The rapid pace of modern life, as well as chronic work and academic overloading, contribute to our society’s progressively increasing stress levels. Chronic stress can affect both physical and mental well-being. Numerous studies have confirmed that viewing a nature-based video presentation can reduce stress and result in attention recovery. However, the discourse has been primarily focused upon stimulation applied over a single duration, rather than over various durations. Therefore, the present study explored the effect of various viewing durations with regard to forest-related videos on stress reduction and attention recovery. Before the videos’ presentation, the participants’ stress and distraction levels were increased through stimulation. Data on stress, attention, and relaxation were collected through the implementation of the State–Trait Anxiety Inventory and an electroencephalogram instrument. Equal numbers from the 90 participants (i.e., 30) were assigned to watch a short, medium-length, or long video (5, 10, and 20 minutes in duration, respectively). The viewing of 20-minute forest-related videos significantly promoted stress reduction and physiological relaxation. The present findings advance the understanding of the relationship between viewing nature scenes duration and psychophysiological states; thus, they serve as a reference for future research on the natural-dose concept, as well as the development of relevant activities and courses.
