You probably know that exercise is good for you and that daily activity is associated with improved health. A lower risk of weight gain, diabetes, heart disease and some cancers are among a long list of positive health effects of physical activity. Lesser known benefits include improved mental health, cognitive function and greater feelings of wellbeing. What you may not know is that where you exercise matters and that exercise outdoors, especially in nature, can be particularly beneficial. This is not surprising given that being active in a natural environment has been shown to have an impact on mental health. Indeed, activity outdoors leads to enhanced feelings of energy and diminished fatigue, anxiety, anger and sadness compared to similar activity conducted indoors. Additionally, some research suggests that outdoor activity may improve attention in adults and children. Research has uncovered additional benefits of simply going for a walk outdoors in nature as well possible explanations as to why. These studies show that participants who went for a walk in a quiet, tree-lined area experienced greater improvement in mood – they felt happier – than those who walked along a busy street in an urban area. The researchers also completed brain scans to determine that the difference in mood was related to changes in blood flow in the brain. The finding that being active in a natural environment caused physiological changes that led to psychological benefits is exciting! Another advantage of exercising outdoors is that you might get a better workout. This is mostly due to the fact that you will likely walk or run faster outdoors, but other factors like varied terrain, hills and wind resistance add to your effort. Research shows that even though people tend to exercise at a higher intensity outside, they don’t necessarily feel it. In fact, ratings of effort are lower outdoors for the same exercise. This is partly because the pleasant visual stimuli outdoors distracts you from unpleasant sensations of effort during exercise. This is the same reason that listening to music makes exercise more enjoyable and why fitness centers have televisions on the walls or built into exercise equipment. Think of the outdoors as a really big TV screen!
