My intense dislike of the gym just got a scientific underpinning: A meta-analysis reveals that exercise done outdoors has more benefits that the one indoors. A meta-analysis is not a study from scratch but reviews already existing studies. In this case, researchers tried to figure out if there are benefits to exercise in a natural outdoors environment vs a confined gym.
The disadvantage of a meta-analysis is that the original studies might be flawed – in spite that the researchers tried to weed out those studies – and that their flaws get compounded. In this case, the original studies were furthermore hampered by not using objective measurements of wellbeing but “self-reported” statements: People just talked about how much better they felt outdoors than indoors.
And so the 833 individuals sound less scientific but gushing when reporting how they are feeling after their exercise in nature: “Compared with exercising indoors, exercising in natural environments was associated with greater feelings of revitalization, increased energy and positive engagement, together with decreases in tension, confusion, anger and depression. Participants also reported greater enjoyment and satisfaction with outdoor activity and stated that they were more likely to repeat the activity at a later date.”
I believe them even without a proper study because going to a gym would make me depressed – and I am not a depressed person to start with. On the other hand, when I putter around in the garden, I am suffused by bliss. Working out on my ages-old NordicTrack machine in the basement strengthens my muscles; going cross-country skiing lifts my spirit.
Clearly, working out in a gym increases endorphins and makes one feel better. But outside, we have the added benefit of light in our eyes and on our skin – which has been shown to decrease depression and boost vitamin D production. For once, Boston did not have another snow storm today so that I could not fill my outdoor needs by snow shoveling but I hacked away on ice for a good hour – to prepare for the next snowfall which is forecast for this week.
Outside, there's also less pollution. Contrary to common assumptions, indoor pollution generally is much higher than outdoor pollution (unless you live directly at a busy highway or near a spewing factory) – thanks to detergents and other cleaning supplies, cosmetics, wood preservatives, paints, varnish and lacquers, drywalls, molds, radon, asbestos, carbon monoxide, copiers, printers, correction fluid, glues and craft materials, wax, permanent markers, adhesives, degreasing products, building materials, upholstery, wall-to-wall carpeting and other floor coverings – to name some.
Therefore it is recommended that we aerate each room at least twice a day by pushing the windows open for fifteen minutes. And that we sleep with windows open all night. Asking around, I find that not many people do either.
Outside has usually uneven terrain – different from the even floor of a standard gym. The unevenness leads to better muscle workout – without that we notice the extra effort. This lowers blood pressure and might stave off Parkinson's.
Another advantage of the great outdoors is the color green: We are hard-wired to love a green landscape because green signals plants that produce oxygen and food for us, and hold precious water in place. Green is soothing to our eyes, and to our minds. There is not much life in eternal ice or the dry desert – green is our life. You can reduce indoor air pollution by having houseplants – heartleaf philodendron, spider plant and ficus are not hard to keep alive.
For the benefits of outdoors, let’s not forget the smell of flowers, mowed lawns, freshly turned soil. And the sounds: birds’ songs, rustling wind, lapping waves, babbling brooks – music to our ears.
Of course, researchers now call for better studies to measure all that. But you and I have known it all along: Outdoors is better! Read More

De-cluttering Your Home, Your Mind, Your Life
May 6, 2010
Believe it or not: A cluttered home is a severe stress factor in your life – at least, if I believe my patients. An untidy home makes people feel inadequate, ashamed and asocial. Because their homes are so messy, they don’t invite people over and become more and more isolated.
Feng shui, the Chinese art of bringing luck, health and prosperity to your life seems, on first look, rather outlandish – another form of quackery. On second look, feng shui (literally “wind water”) wants you to tidy up your place.
Actually, the “water” part refers to the place where you choose to live: It has to be at an “auspicious” spot - which sounds like weird magic. But in olden times, the perfect dwelling spot was near water; today, without having an inkling of feng shui, what appeals to us – a green neighborhood, a view from a little hill, not much traffic – is also a healthy choice (unless there is an undisclosed toxic dump nearby…).
The “wind” part means – at least in my interpretation – that you have to create space so that the wind can blow freely around in your home - a fancy way of saying you have no clutter around. The Chinese also call this wind “qi” (pronounced chi) - the positive life energy. In your house, is a visitor greeted by a pile of shoes, old newspapers and stacks of plastic bags that long should have been carried out to the garbage? Or is your entrance welcoming?
Now, with my cosmic greed for books, the wind has a bit of a hard time here. BUT those books I do love, they are not a burden on me, and I keep them in order by handing down some, from time to time, to local schools. I am really not the tidiest of persons. But here is a little secret, handed down from my late, beloved mother-in-law Hilde: If you don’t have time for big cleaning, at least keep the table free of clutter. Try it – immediately, the room looks better.
And here is the Ten-Minutes-De-cluttering Program I developed for my patients who are drowning in disorder and depression:
Have an egg timer (I use an egg timer for all sorts or weird things). Put it on ten minutes. Start de-cluttering in a corner – any corner, but preferably at the entrance. For everything you take into your hand, find a final place: file or shelf room, garbage, charity. And one box with "Cannot yet make up my mind." That box you store for one year; then throw it out.
When the egg timer rings, you are done for the day – unless you suddenly find yourself in the mood of doing some more. Next day, you do the same – even if you did over-time the day before. If you do only ten minutes per day, your place can’t but get "windier" – and you can’t but get relief. Read More
