6 Surprising Ways Nature Improves Your Memory And Productivity
Not only because trees are the highest free-standing organisms that have ever lived, but because trees - with their many restorative properties - save the U.S. $6.8 billion in health costs every year.Yet we're spending less and less time with our vertically gifted arboreal friends.Advertisement
According to the Proceedings of the National Academy of Sciences, nature-based recreation has fallen off by 35% in America over the past 40 years.
This is a problem, since the evidence suggests that trees make us happier and healthier.Let's leaf through the reasons why.
1. Trees may save your life.
A new "Environmental Pollution" study found that trees prevented a whopping 650,000 cases of acute respiratory symptoms and 850 deaths, the Atlantic reports. It's because trees deal with our pollution.
2. Trees help you de-stress.Research subjects who took forest walks (instead of walks in cities) had a 12.4% decrease in cortisol - a hormone associated with stress - and a 1.4% decrease in blood pressure, plus a 5.8% decrease in heart rate. It's like anxiety medicine, but free.
3. Trees make a good neighbor.A study of 10,000 Brits found that people "experienced lower levels of mental distress and higher levels of well-being when they lived near green space in their urban area." Advertisement
The takeaway: Psychologists say to hang out at the park at least once a week. Japanese has a great word for fit - shinrin-yoku, or forest bathing.
4. Trees help you remember.
A University of Michigan study found that people who walked around trees did 20% better on a memory recall test than those who wandered around urban pathways. So if you're studying something all day, a walk in the park not only helps you recover, it also helps to recall.
5. Trees give you energy.Just looking at trees made study subjects get rid of mental fatigue. Scientists say this is because nature gives us a sense of awe, which is one of the most restorative emotions we can experience. Advertisement
6. Trees help you concentrate.
Study subjects who walked through the woods scored better on a proofreading test than those who rested in a chair or walked through town. The effects were so pronounced that the researchers concluded that "doses of nature might serve as a safe, inexpensive, widely accessible new tool ... for managing ADHD symptoms." In other words, more trees, more focus.
Bonus: If you're looking for a particularly awesome tree to fall in love with, consider the Banyan Tree. They're gigantic.
