The experiment is still on: How long into the winter will I succeed to keep up my daily twenty-one laps in the pool?
So far, so good. The water is much colder now, but the days have been sunny and friendly – the fog lifted while we were at the East Coast.
Truthfully, lately it has been harder to face the pool: I am still battling a minor cold, and every day I have to decide if it is prudent to swim with the cold, or if I should just snuggle up in a warm blanket. But the exhilarating feeling after my daily swim – I seem to be addicted to it. I look full of vigor. My posture definitely is straighter. I am building up muscles where I never had any – on my back and my arms. Plus, the tiny belly I had is getting smoother (not smaller).
On the negative side is my skin. No outright rash or itching yet, but I have the suspicion that my skin looks a bit older, notwithstanding the coconut oil I slab all over me after each bath.
For a few days, I had been getting extremely cold after each swim, and couldn’t get warm at all. If you ever read my water book, you know that staying cold after water exposure is not a good idea. But with my inborn stubbornness (which might just get worse with age …) and medical curiosity, I kept doing what I should not have done: go swimming. And got colder and colder. In spite of the knee bends, blankets and hot tea with fresh ginger. Two nights in a row, I didn’t get warm all night – certainly not a healthy state!
Until yesterday. Shortly after I went swimming, had taken my short cold shower to get rid of the chlorine, had done my exercise, had rolled up in my blanket and imbibed the tea, I got really warm. Even my hands felt tingling with warmth. This lasted all night, and is still going on. I suddenly had the feeling that, for the first time in my life, that I was getting on the warm side in life. Like, where my husband always is.
Looking around for an explanation, I stumbled onto brown fat. Brown fat gets activated by cold. Brown fat is supposed to be healthier than yellow fat that just stores superfluous calories. Babies have more brown fat because it protects them from hypothermia – a constant threat for newborns.
Brown fat is not so much fat but is related to muscles. Brown fat is brown from the mitochondria and their iron contents; mitochondria are tiny energy factories. Brown fat has also more blood vessels for better oxygenation and is metabolically more active than yellow fat – it actually burns calories instead just storing them.
So, by swimming in the cool pool, I must have tapped into my brown fat – I can’t come up with any other explanation. And did you know? Brown fat is implemented in weight loss. Yes! Brown fat can make you lose weight – IF you have enough brown fat.
Sebastian Kneipp, the father of the Kaltwasserkur (Cold Water Cure) is famous for jumping into the wintry Danube River to cure his tuberculosis. Later, he modified his approach because he observed that some weakened patients were not able to withstand the bitter cold he himself had applied to his body. One could say he watered down his original approach … I had always repeated what I had been taught: that too much cold might be hazardous to your health. Which still might be true for frail people.
But I might be onto something here … I will let you know how this will work out.
P.S. After today's laps, I have very warm hands. Read More

Sweating It
July 31, 2010
Awful, this summer heat, isn’t it? One sits, barely wants to move, and sweat runs out of every pore.
Actually, no! Sweating takes out toxins from our bodies; the skin is one of four elimination organs (the other three are kidneys, bowels, lungs). Sweating is beneficial. Enjoy your wet armpits – without them, you would age faster and might get cancer earlier. Sorry that I am so graphic. But the advantages of sweating are widely underrated.
People sit in air-conditioned houses, and at the same time they are shelling out big dollars for “colon cleansing.” Colon cleansing is a health scam. Eating better and drinking water or herbal teas will do the trick; colon cleansing will not make you purer - just poorer.
In the winter, a sauna does the trick. Not by accident was sauna in vented in Finland and Russia - cold, northern states that do not allow for sweat naturally. - Exercise can make you sweat. But don’t try too hard: Individual people start sweating at different points, and one should not exercise for the sake of sweating. Move for fun and purpose!
In the summer, let nature work for you: Sweat it out!
Heavy metals like nickel, copper, zinc, lead have been found in sweat in higher numbers than in the blood – but I wish, we had better studies available! For instance, I am only aware of a single study that saw mercury levels falling during a sauna protocol. Most medical studies are funded by pharmaceutical firms (and I don’t see any wrong in there, as long as they adhere to scientific ethics). But this situation leaves out studies on water, sauna, yoga, healthy food, to name a few – because not much money can be made of them. The only way to improve the situation is to demand such studies.
Medications may be released into the sweat, notably anti-epileptic drugs, amphetamines, methadone (but don’t get your hopes too high that sauna will get you through a drug test easily - it won’t!).
Sauna also prevents frequent colds and promotes better sleep. In Europe, people use saunas widely. Mostly, of course, for relaxation and fun.
Except for the very elderly and frail who are in danger of severe dehydration in the summer, an air conditioner is unnecessary. In our house, we have a built-in central air-conditioning system. We never – never! – use it (but we also live in Boston, not in the Deep South - perhaps I would feel different in New Orleans...). If it gets really sweltering at night, we run a simple fan in the bedroom. Summer is for sweating – and winter is for cold exposure; both have their health merits.
If you sweat, you lose salt and water. So drink enough! And put a pinch more salt than usually in your food to replenish – unless you tend to high blood pressure. - And before I forget it: Warm drinks are healthy; cold drinks - especially ice-cold - hurt you.
Instead of suffering through the summer months, take them as what they are: A free-for-all detox program – every year! Eat fruit and salads and enjoy the heat with a peppermint tea ... lukewarm. In the shade. Read More
