In this early study, it was reported that the blood pressure lowered in subjects who were put under the stress of reading loudly when they started looking at an aquarium that had fishes swimming. A similar study was conducted in the same year by Friedmann and his colleagues and this study also revealed that there was a reduction in the blood pressure of children when they were in the company of a dog following exposure to the stress of reading loudly. In 2002, another study was done by Allen, Blascovich and Mendes and this study reported similar reductions in heart rate and blood pressure following a stressful exposure, when a cat or a dog was present with a person. This study went further and revealed that the affect of these pets was more significant in comparison to the presence of a loved one. The work of these researchers was important because their studies helped in assessing an important factor that is the presence of pets provided for a reduction in the cardiovascular response following stress.
Dr. Wells performed this study based on a similar hypothesis that the cardiovascular impact on an individual following viewing of the recordings of animals should be similar to the presence of live animals, that is these recordings should lead to a lowering in the cardiovascular response of a person in stress. The purpose of this study was to assess and confirm if the recordings of animals led to a reduction in the blood pressure and heart rate of a person following the stressful exposure. This assessment was important because no study based on the recordings of animals was conducted in the past. Also, it was significant because many individuals cannot keep live animals and this study would be helpful for them in stress reduction and lowering of blood pressure and heart rate in stressful situations.
The participants of the study included hundred healthy university going students out of which 58 were males and 42 were females. The ...Show more
