A tremendous lightning-and-thunder storm brought a huge downpour and a bit of cooling to our region. Not much so. It is nearly ten o’clock at night, and I am still sweating.
You hear me often talk of the benefits of a cold shower (after the hot one). The cold water mimics the exposure to cold we need for a functioning immune system. Since we live in rooms with central heating and are not working outside so much, we don’t get enough of our birthright: cold exposure.
We likewise don’t get enough of the summer heat because most of us live in air-conditioned rooms. Not we though. In twenty years, we have used our central air conditioner a single time. We didn’t like it. We prefer to sleep with window open to get cleaner air. Contrary what you might think, the indoor air pollution usually is much worse than the outdoors air pollution. Hint: Houseplants help cleaning up indoor air.
We sleep with window open even in winter, in severe minus grades. I lie under about five duvets then and stay snugly warm.
Now, in summer, I am sweating – I can’t remember a hot and humid summer like this one. But sweating: That is what summer is for. Summer is a season that gives you a sauna for free: You can sweat out toxins which otherwise are hard to eliminate. Now I am getting rid of waste and damaging agents about twenty hours a day. Of course, I make sure that I take in enough water and salt, to make up for the losses. And be reasonable about it: If you have a medical condition, switch on the air conditioner. Keeping a cold facecloth at hand or taking a short cold shower can keep you cool.
I feel uncomfortable now, sweating. But I know I good I will feel come September: Cool and ready to work hard again. In this heat, I admit, working and writing comes nearly to a standstill; the garden slowly turns into a jungle again as if the months of weeding and pruning never happened. This is the time for cold black tea with mints from the garden, reading in the shade, enjoying delicious music and light dinners – cold fish with a salad and some cherries afterwards. On the weekends, I am planning long afternoon naps, This is not my most effective time – but it is getting me ready for work and creativity in the fall.
Soon I will give you my summer reading list. But for now I am in the middle of the summer string camp with two hundred kids playing violin, viola, cello and bass – and I am one of them. The one who plays cello badly. But having fun.
In an air-conditioned room, actually. Read More

I Hate The Gym – You Too?
February 6, 2011
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
