Popping sealed air-capsules to reduce stress

30 undergraduate students participated in a study to assess whether tactile manipulation in the form of popping sealed plastic air-capsules would be stress-reducing. Three of the four dependent measures were significantly changed; subjects reported feeling significantly more energized, less tired, and more calm after popping the capsules. Some advantages to this technique over existing ones include that this technique involves minimum ability, essentially no training or practice, and little likelihood of paradoxical anxiety effects that have been shown to accompany meditative relaxation techniques in some subjects.
