Dr Parr Says…

You probably know that exercise is good for you and that going for a daily walk 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. This is the topic of my Health & Fitness column in the Aiken Standard this week.

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 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!

Almost any indoor exercise exercise can be moved outdoors. While walking, running, and cycling are most obvious, resistance training exercises using body weight and many high-intensity interval training workouts can be modified for outdoors. Yoga, tai-chi, and aerobics classes in the park are also great ways to promote both the physical and psychological benefits of exercise.

Much of the psychological benefit of outdoor exercise occurs in the first five minutes, so even short bouts of activity are meaningful. It also means that going for a short walk outside when you have a break at work or walking instead of driving short distances can have positive effects. At home, taking the dog for a walk, playing outside with the kids, or doing yard work are good ways to be active and reap the benefits of being outdoors.

There are a great many places to walk, run, bike, or paddle outdoors in the Aiken area. With cooler weather on the way, this time of year is perfect for outdoor activity and there are many local events to motivate you to explore the great outdoors. Every little bit of activity you do outdoors will have both physical and psychological benefits to help you become and feel healthier. So, get outside and get active!

Recently I introduced the idea that we live in a “toxic environment,” which provides easy access to high-calorie, unhealthy, inexpensive food and promotes physical inactivity.  The focus was on the toxic food environment, so now it is time to explore our toxic activity environment which makes easy to be inactive and can discourage activity. This is the topic of my Health & Fitness column in the Aiken Standard this week.

Today is Martin Luther King, Jr. Day, a time to celebrate the birthday and reflect on the accomplishments and legacy of Mr. King. It is also a  on which people are encouraged to use their day off from work and school to volunteer in their community. Individuals and groups across the country participate in community service, with some making this their first-time volunteer effort and many more continuing a year-round commitment to service.

You can maximize your impact in community service activities by being fit and healthy. To be sure, there are ways that people of physical abilities can contribute, but many service opportunities require a baseline level of fitness to participate. And it is certainly more enjoyable to volunteer if you aren’t being pushed to your limits. In fact, some service activities are similar in exertion to many forms of exercise and some may be consistent with maximal exercise. Unfortunately, the common pattern of inactivity and obesity can limit people’s ability to function optimally at school, work, or in leisure-time activities, including community service.This is the topic of my Health & Fitness column in the Aiken Standard this week.

The term “toxic environment” was popularized years ago to refer to conditions that promote the consumption of high-calorie, unhealthy food and encourage being physically inactive. This combination is thought to be a major factor that contributes to obesity and other chronic diseases, so understanding both aspects is important. For now, lets focus on our toxic food environment, which I do in my Health & Fitness column in the Aiken Standard this week.
