Nowadays, many of us spend about 10 hours a day in front of a Computer or other electronic devices and less than 30 minutes a day outdoors.The result is that our Brain easily feels tired.We need to give the brain a rest, but how?
David Strayer is a professor of psychology at the University of Utah.He claims that camping may be just what a tech­tired brain needs.His argument finds strong support from Carl and Kate, two experienced campers.Carl, who works for a mobile phone company, says that being outdoors makes him feel relaxed.It also prepares him for the work he must do.Camping gives us a chance to be in touch with nature and it's very relaxing.When you return to work on Monday, you're in a better state of mind.I really like the way I feel on Monday.Kate is a senior editor.She says camping brings her some peace she couldn't have otherwise.She even finds herself more creative.
David Strayer explains that camping allows close contact with nature and being in nature calms the brain and helps it to focus.When people go camping, they need to learn about animals and natural environments; they have to deal with the weather, learn to stay dry in the rain or warm in the snow and have to keep the feet in good condition when hiking and walking.
Some might say that taking a long walk in the woods or by the ocean or in a city park is wonderful, too.But camping requires that one spend more time in nature and it can test him in different ways.And it brings more health benefit as well.
