For years, scientists have been researching how exposing(暴露) humans to nature may improve their physical and mental health. People are encouraged to visit forests and grow houseplants. Now researchers are also testing whether we can get some of the same benefits from experiencing nature in VR(虚拟现实).
Scientists are trying to understand what exactly about nature makes a real difference in health results. One tool that might help is VR, says Hector Alvarez, who wanted to find out if simply seeing nature can relax people. In an experiment, VR allowed him to expose people to the visual(视觉的) experience of nature while controlling temperature, light and air pollution. He is now preparing to publish his research.
People can feel safe faster in environments with lots of plants, Hector explains. "That's why I was interested in VR. If it is right that we feel safe faster in nature, it should bring your stress levels down. "
So far, Hector says, research shows there are some health improvements by experiencing nature in VR. However, they are smaller than those got in the real nature.
Gretchen Daily is an environmental scientist at Stanford University. She agrees at parts of this research, especially in situations without nature. But in the long term, connection with nature in the real world can not be replaced. To some degree, Gretchen worries that the idea might take off that VR can replace the real thing. "If that's taken very far, that' ll be really harmful overall because the real thing is necessary in so many ways, " she says. "We just cannot live on a dead planet. "
