The environment that we live in and make use of is being stripped off its precious components day by day. There are many angles from which the problem of environmental problem can be studied.
Numerous studies in the U. Recognizing those benefits, inthe Japanese Ministry of Agriculture, Forestry and Fisheries even coined a term for it: It means taking in the forest atmosphere or "forest bathing," and the ministry encourages people to visit forests to relieve stress and improve health.
Research is casting light on how spending time outdoors and in forests makes us healthier: Exposure to forests boosts our immune system.
While we breathe in the fresh air, we breathe in phytoncides, airborne chemicals that plants give off to protect themselves from insects. Phytoncides have antibacterial and antifungal qualities which help plants fight disease.
When people breathe in these chemicals, our bodies respond by increasing the number and activity of a type of white blood cell called natural killer cells or NK. These cells kill tumor- and virus-infected cells in our bodies. In one study, increased NK activity from a 3-day, 2-night forest bathing trip lasted for more than 30 days.
Japanese researchers are currently exploring whether exposure to forests can help prevent certain kinds of cancer. Spending time around trees and looking at trees reduces stress, lowers blood pressure and improves mood. Numerous studies show that both exercising in forests and simply sitting looking at trees reduce blood pressure as well as the stress-related hormones cortisol and adrenaline.
Looking at pictures of trees has a similar, but less dramatic, effect. Studies examining the same activities in urban, unplanted areas showed no reduction of stress-related effects. Using the Profile of Mood States test, researchers found that forest bathing trips significantly decreased the scores for anxiety, depression, anger, confusion and fatigue.
And because stress inhibits the immune system, the stress-reduction benefits of forests are further magnified. Green spaces in urban areas are just as important as rural forests. Gardens, parks and street trees make up what is called the urban and community forest.
These pockets of greenspace are vitally important because they are the sources of our daily access to trees. Spending time in nature helps you focus.
Our lives are busier than ever with jobs, school, and family life. Trying to focus on many activities or even a single thing for long periods of time can mentally drain us, a phenomenon called Directed Attention Fatigue.
Spending time in nature, looking at plants, water, birds and other aspects of nature gives the cognitive portion of our brain a break, allowing us to focus better and renew our ability to be patient.
In children, attention fatigue causes an inability to pay attention and control impulses. Studies show that children who spend time in natural outdoor environments have a reduction in attention fatigue and children diagnosed with ADHD show a reduction in related symptoms.
Researchers are investigating the use of natural outdoor environments to supplement current approaches to managing ADHD. Such an approach has the advantages of being widely accessible, inexpensive and free of side effects. Patients recover from surgery faster and better when they have a "green" view.
Hospital patients may be stressed from a variety of factors, including pain, fear, and disruption of normal routine. Research found that patients with "green" views had shorter postoperative stays, took fewer painkillers, and had slightly fewer postsurgical complications compared to those who had no view or a view of a cement wall.
What happens if we lose trees? The invasion of the emerald ash borer, or EAB, Agrilus planipennis since has provided an unfortunate opportunity to look at the effect of tree-loss on human health. EAB is a non-native, wood-boring beetle that kills all species of ash Fraxinus trees within three years after infestation.
In some communities, entire streets lined with ash were left barren after the beetle arrived in their neighborhood.
A study looked at human deaths related to heart and lung disease in areas affected by EAB infestations. It found that across 15 states, EAB was associated with an additional 6, deaths related to lung disease and 15, heart-disease-related deaths.South African environmental law describes the legal rules in South Africa relating to the social, economic, philosophical and jurisprudential issues raised by attempts to protect and conserve the environment in South Africa.
South African environmental law encompasses natural resource conservation and utilization, as well as land-use planning and development.
