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

Sebastian Kneipp Wins – I Lose
November 28, 2011
Traveling earlier this month in Europe, I missed my daily swimming in the pool so much that I filled a bathtub in the hotel with water to the brim and got in. Now, it happened to be Frankfurt/Main in late fall, and the water was cold. How cold? I don’t travel with a thermometer but it was definitely colder than my Californian pool.
But I enjoyed it. I got in to my neck, and stayed for a while. As it turned out, I stayed too long. Although the rest of my body heated up soon after I had toweled myself off, an ice-cold area over my kidneys the size of a football stayed with me – literally for days.
Uh-oh! I had overdone it! And Sebastian Kneipp had told me so. He used to warn that one should not exaggerate cold exposure. And as difficult it is to give exact numbers for the time frame of “too much” – if one stays cold in the kidney area for days after, as it happened to me, one clearly has gone too far.
Originally, he had cured himself from consumption (tuberculosis) by jumping into the winter-cold Danube River several times a week. When he later tried his method on other people, he quickly realized that not every body was not made for such endurance test: The older people were, and the thinner, the less cold they could handle – and he adjusted his theories to this insight.
In Traditional Chinese Medicine “qi” is the life force, and is generated in the “kidneys”, which is actually what we call the adrenals. In Western Medicine it is known that that the adrenals produce a hormone/neurotransmitter called adrenalin, which is an energizer. If you stimulate the adrenals a bit, it will give you that desired energy jolt; if you over-stimulate the adrenals, you get a downer.
Now, after two weeks of down time, when I didn’t dare to face the cold again, I swam again in the pool today. The temperature was 15 degree Celsius (59 Fahrenheit). I only swam one lap – wasn’t brave enough for more.
One lap might be too short to induce brown fat in my body, but it was exhilarating, and when I got out, my kidneys felt fine! And I restarted in time to strengthen my immune system for the winter. Read More
More About Brown Fat
November 2, 2011
My experiment is going on. Of course, I have no idea if it is really new brown fat that turns me into an oven every time after my daily cold laps in the pool. For all I know, I could have a not-yet-recognized infection or any other disease that makes me burn up. Only thing I know is that I feel terrific – for the moment.
But for the sake of an interesting exploration, let’s stick with my brown fat hypothesis. This is what I have learned about about brown fat so far:
1. It used to be thought that only babies (protecting them from hypothermia) or bears (keeping a reasonable core temperature during hibernation) have brown fat. It turns out that traces of brown fat are still around in adult people. – A little aside: Other ways to increase body temperature are increasing surrounding temperature, moving about, shivering, and eating certain “warming” foods like cinnamon, ginger, onions, garlic, rutabaga, coriander, cloves – interestingly foods often used in the winter kitchen. But there is no hint that those foods increase brown fat. Or a shred of a proof that a so-called "Brown Fat Diet" will increase that precious tissue in your body.
2. Brown fat can help weight loss by increasing metabolism speed.
3. Brown fat also can decrease elevated insulin-resistance (also called pre-diabetes) and a diabetic situation.
4. Brown fat can be induced to increase by cold exposure – be it by swimming in cold water, immersing in a tub filled with ice water, or dancing in a walk-in food refrigerator (don’t you wish you had one of those at home??).
5. Needless to say, there are already pharmaceutical firms are already working on drugs that might trigger growth of brown fat, without going through the ado of cold exposure. The easy way out, I call it. And definitely not an interesting way, if you ask me.
I like to think about cold-induced brown fat as one of the benefits of moderate stress. We all know that stress is bad for you, don’t we? Not necessarily though. Moderate stress might be what makes the body function in the way Nature intended it. With heated dwellings with forgo the winter cold stress – and get sick for it, lacking brown fat. With air-conditioning in the summer, we miss out on the sweating which give our body a good cleanse of all the toxins – and get sick for it. Occasional hunger stress (fasting!) is another beneficial stress mechanism. Not only do we get healthier on occasional fasting, and live longer with less belly ballast, it also seems we get to be happier with fewer pounds – and less depressed.
One estimate is that there are about three million residential swimming pools in California (I am not even mentioning the pools in Florida and all across southern U.S.A.). If these pools are anything like our pool here in La Jolla, all those turquoise eyes should be gazing at the sky, basically unused. All, of course, using up precious water resources. How about using them? If you are in decent health (ask your physician), you start by doing a single lap across your pool. Tomorrow two, and every day one more until you reach twenty-one laps. The brown fat will appear very fast – and will help you lose weight.
Putting on brown fat, however, might mean walking a fine line: You want to increase your metabolism by cold exposure. But you don’t want to get where most winter swimmers end up: with more fat on their bodies. Fat (of any kind) protects against cold, and makes you better able to withstand long swims in icy water. Don’t go there! Read More
