[originaltext]M: Mrs. Hudson, a new research shows that even just five minutes

M: Mrs. Hudson, a new research shows that even just five minutes of exercise in a natural setting can significantly boost our mood. But, is it true that can have such a magical effect?
W: To a certain degree, I have to say yes. Because exercising in natural areas is not only good for our physical health—it can also improve our mood and sense of well-being in as little as five minutes.
M: So if we go for a walk in a park or work in a garden, we’re giving our mental health a good boost. But how was the result discovered?
W: Before this, exercise alone was known to make us happy. So was being in a natural setting. Scientists wanted to see the effect of combining the two.
M: So what did they do?
W: They evaluated ten different UK studies involving more than 1,200 people. Participants had taken part in activities such as gardening, sailing and country walks, and rated their mood and self-esteem.
M: What did the scientists find in the research?
W: They found that in a natural setting even a few minutes’ exercise can really promote the mood. The research showed that their mood and self-esteem got a significant boost with as little as five minutes of outdoor exercise. And people with mental disorders benefited the most.
M: Wow, this is the first study to quantify the amount of time needed to get a positive effect. So, maybe, if you want to be happy, just head out for a walk in the park.
