As things like whatever you’re reading this on have made us more sedentary, researchers have found that even low intensity physical activity has measurable health benefits, including the biggest benefit of all: a longer life.
A recently published study by an international team found that doing more physical activity – even something as simple as cooking, washing dishes or walking slowly – is linked with a lower risk of early death in middle-aged and older folks.
You may have heard or just assumed that you need to break a sweat or get your heart rate up to the point that you’re panting for exercise to really be of any benefit.
People with busy modern schedules may have a hard time fitting in all that sweating, especially when you add the time it takes to get ready and then clean yourself up afterward.
“It has previously been widely assumed that more is better in terms of physical activity for health,” said Tom Yates, a professor at the University of Leicester and a co-author of the paper, which was published in the journal BMJ. “However, this study suggests health may be optimized with just 24 minutes per day of brisk walking or other forms of moderate-intensity physical activity.”
“Another important finding was that spending 9.5 hours or more each day sedentary – which essentially means sitting – was associated with a statistically significant increased risk of death, with each hour more above this threshold increasing the risk of death further.”
Co-author Charlotte Edwardson, also from Leicester, said the study reinforces the idea that ‘doing something is better than doing nothing,’ even if it just means standing up for a bit at work.
“A large risk reduction was seen between the least and the second least active group suggesting that incorporating some time doing physical activity, light or moderate intensity, in daily life is associated with a big health benefit.”
Living a longer life could be as simple as standing up while you read things like this, so long as you’re not crossing the street.
Gadgets and their ever increasing speed have become firehoses of information. Our nervous systems are awash in bits and bytes by the trillions around the clock whether we’re online or not, awake or sleeping. In this talk, Pack will describe vital behavioral strategies we can re-learn and re-purpose to leverage and focus upon to create virtuous feedback circles.
Pack Matthews is known in Columbia, Missouri primarily as a local musician, yoga instructor and piano tuner, and has recently added the moniker “inventor” to his credentials. His passions are numerous and leave him making hard choices to avoid becoming a jack of all trades. So far he’s keeping them focused on Jazz piano and bass while devoting most of his time to his start- up, mysoulseat.com. He particularly enjoys unearthing the depth of talented people here in Columbia.

In the world of health research, exercise is one of the few things that pretty much everyone agrees on.
Regular physical activity improves heart health, reduces your risk of cancer, keeps your bones healthy, improves mental health, and the list goes on.
But does it matter where you do your exercise? Will a gym work-out have the same health benefits as a bootcamp in a local park?
The bottom line is any exercise is better than no exercise, doctor and researcher Sandro Demaio tells ABC Life. So if exercising indoors works for you, stick with it.
“But there is some interesting evidence that running on a treadmill does not give the same mental health benefits as running outside, and it may not give you the same happy hormone boost as running outside,” Dr Demaio says.
“That makes sense because you’re not just running to improve your heart health and get the blood moving around the body and improve your fitness. You’re also outside seeing things, smelling things and getting fresh air. All those things will have an effect.”
Time in nature can boost mental health
It turns out, simply ‘being’ in a beautiful, natural environment really can benefit your mental health.
Levi Wade is a University of Newcastle PhD student studying the effects of outdoor exercise on mental health and cognition in teenagers.
“There’s a big evidence base on its effect on concentration and stress reduction. Those are the two big effects you’ll find,” Mr Wade says.
Broadly speaking, we can exert two different types of focus: hard and soft. Doing homework, checking over a spreadsheet, or crafting a pithy email all require hard focus.
Being immersed in a beautiful natural environment, on the other hand, can stimulate our soft focus. You might acknowledge the rustling of the leaves, or pay attention to the bird life.
Switching to soft focus allows your hard focus to recover: this is referred to as the restorative effect.
“If you’re walking in a forested environment or just somewhere that’s fascinating and beautiful, then a lot of the mechanism behind that effect on stress and mood is due to that environment taking your mind away from your own problems and whatever stress you are experiencing,” Mr Wade says.
“It’s just relaxing your mind because you’re not focusing on those thoughts.”
Much of the research around these benefits of outdoor exercise has been conducted on walking — specifically, walking in forested environments in Japan. It’s a popular activity there (not surprising given that 65 per cent of the country is covered in forest) and it’s termed shinrin-yoku, or “forest-bathing”.
One of the world’s leading shinrin-yoku researchers is Professor Yoshifumi Miyazaki, who has been conducting research on the physiological relaxation effects of nature since the early 1990s.
“The most important thing is to make use of nature that you like,” he says.
“During our research, we found that even small elements of nature that you personally like, like plant aromas, flower arrangements, potted plants, or bonsai can have a physiological relaxation effect.”
Of course, sitting next to a potted plant for halfa won’t have the same effect on your health (physical or mental) as a 5k run. But if you’re feeling overworked, then taking some time away from the city is likely to make you feel better.
Then there’s vitamin D boost
Exercising outdoors is also a great way to get your vitamin D, which you need for healthy bones, muscles and other vital body functions.
If you have fair skin you need roughly around 5–15 minutes of sun exposure a day, but this can vary depending on the time of year, and where in Australia you are.
It’s common knowledge that there are many benefits to being fit, but one large new study found that skipping out on the gym is practically the worst thing you can do for your health. In fact, the study claims not exercising might be more harmful to your health than smoking. New findings, published Friday in the journal JAMA Network Open, detail how researchers at the Cleveland Clinic studied 122,007 patients from 1991 to 2014, putting them under treadmill testing and later recording mortality……..
