Just five minutes of exercise a day outdoors can improve mental health, according to a study.
Researchers from the University of Essex, UK have found that as little as five minutes of a “green activity” such as walking, gardening, cycling or farming could help to improve mood and increase self-esteem (自信).
Many studies have shown that outdoor exercise can reduce the risk of mental illness and improve a sense of well-being, but the new study, led by Jules Pretty and Jo Barton, was the first to determine how much time needed to be spent on green exercise for the benefits to show.
Barton and Pretty looked at data from 1,252 people of different ages, genders (性别) and mental health status (情况) taken from 10 studies in Britain.
They analyzed their different outdoor activities including walking, gardening, cycling, fishing, boating, horse-riding and farming in locations such as a park, garden or nature trail (路径).
They found that the mental health changes were seen after just five minutes. With longer periods of time exercising in a green environment, the positive effects were more apparent.
Looking at men and women of different ages, the researchers found the health changes were particularly strong in the young and the mentally ill.
Green and blue
A bigger effect was seen with exercise in an area that also contained water – such as a lake or river.
“This is because historically we are drawn to water to survive and it is in our genetic (遗传的) make-up to be at one with nature,” the researchers wrote in their report.
Pretty said those who were generally inactive, or stressed, or with mental illness would probably benefit the most from “green exercise”.
“Employers, for example, could encourage staff in stressful workplaces to take a short walk at lunchtime in the nearest park to improve mental health.”
He also said exercise programs outdoors could benefit youth offenders.

【小题2】What can we conclude from the findings of the study?
A.Gardeners and farmers do not need “green exercise”.

D.“Green exercise” is not suitable for the mentally ill.
【小题3】According to Pretty, _______ would probably benefit the most from “green exercise”.

Only about 30 percent of people in the US know how to perform CPR (心肺复苏术). Recently, a 9-year-old boy showed a Georgia woman how to perform CPR on her newborn baby.
Susanna Rohm said she had experienced a parent’s worst nightmare (噩梦) — her 2-month-old son, Isiah, was not breathing. “I noticed he looked pale. I looked at his arms and his legs and they were limp (无力的),” Rohm told a local newspaper. “Then I noticed that he looked like he wasn’t alive.” Indismay, she dropped and broke her cellphone. Rohm had to run into the street, screaming for help.
“I had him in my arms and screamed over and over. Then I ran outside. I saw two boys playing across the street, and I yelled, ‘Go and ask your parents to call 911,’” Rohm said. But the two boys were able to do more than that. Nine-year-old Ethan Wilson took action, showing Rohm how to perform CPR on little Isiah while ten-year-old Rocky Hurt helped as well.
Rocky said he had learned the CPR technique from a poster in a health class at their school, Sedalia Park Elementary. “I was thinking we’d better give her a helping hand instead of getting scared,” Ethan said. “I told her to push on the baby’s chest five to ten times a minute with only two fingers, tilt back the baby’s head, plug the baby’s nose and breathe into the baby’s mouth,” Ethan said in an interview.
At last, Isiah began crying and was breathing again. He spent two nights in a local hospital. “If the little boy hadn’t shown me what to do right there, my baby would probably not be alive right now,” Rohm said.
