One aspect of my cold pool experience is that, every day, with my twenty-one laps, I am sucking up vitamin D - so to speak. The vitamin is manufactured under the skin with sunlight – or even just daylight, on a cloudy day.
There is not one vitamin D but several. The precursors are taken up with food – all vitamins D are fat-soluble, so a fat-free diet doesn’t do a thing for you. And then these precursors are metabolized under your skin with sun exposure. As we age, or with darker skin, we require more light to do the job.
And don’t think that “fortified” milk, yogurt or cheese will provide you with the right amount of vitamin D. They will only make any disease in your body worse because they are inflammatory. Also, there are several forms of vitamin D, your physician should supply you with a vitamin D preparation, particularly in the winter and particularly if you are living in the inner city where light might be filtered away by high buildings and smog.
Vitamin D is important for several reasons:
1. It protects you from all kind of cancers. And, please, don’t be afraid that you catch skin cancer from that short of an exposure – not more than twenty minute. On the contrary! The other mostly unknown fact about skin cancer is that vegetables protect you from skin cancer much better than a sunscreen. Disclosure: I don’t use any sunscreen, ever. I usually dress with long sleeves, long pants and a sun hat. But I don’t fool myself with sunscreen: They are not doing the job they advertise they are doing.
2. Sun and day light protect you from the so-called winter blues – Seasonal Affective Disorder (SAD). The more northern you live, the more at danger you are for depression, and the higher the incidence of alcoholism is. So, go out daily, at around noon, sun or rain, and fill up on light! You also get the exercise and the joy of walking in a park, or even just on a bustling street.
3. Vitamin D is essential for your bone health. Vitamin D is important for uptake of calcium and phosphorus, among others, from your bowels – without vitamin D the food or pill just passes you by. You also, of course, need a diet high in plant material so that you have access to all the minerals your body needs – because calcium alone doesn’t do a thing for your bones.
4. Vitamin D is essential for immune function - it protects your health in so many ways, not only against cancer. It also plays a role in warding off the common cold and the more dangerous flu. A virus alone can’t kill you – you also have to have a weakened body and a low immune function to make you susceptible to death and disease.
5. Insufficient vitamin D seem to lead to diminished intelligence and autism in children, and to dementia in older people.
6. The lack of vitamin D seems to be involved in the development of multiple sclerosis (MS). Being outside - especially in your youth - protects you.
7. Low vitamin D in your blood makes you more vulnerable to stroke – it is easy to see if you don’t eat fresh food and never get out of the house, that you immediately are at higher danger of vascular events.
8. Vitamin D seems to prevent or improve several other diseases like rheumatoid arthritis (RA) and asthma – and it protects against radiation damage.
All this I get from my twenty minutes in the pool each day. And that is apart from the cold stimulus and apart from the exercise I get.
Should we not start a movement making people use their unheated, underused pools more? – If I only knew how! I am such an apolitical person.
And I admit publicly: It is hard every day to walk into that cold pool. – But isn’t everything worthwhile hard? Like raising a family, doing your job day-in, day-out, learning a new skill – and being afflicted by a bad, possibly preventable disease? Read More

Taking Care Of Oneself
September 5, 2011
At a dinner, I came to sit beside a beautiful French lady of a certain age, elegant and sophisticated. Always looking for good stories and good advice, I asked her what she did to keep her weight. She gave me that long look, shrugged her shoulder and said: “One takes care of oneself.”
I have often thought of the French lady’s remark. It sounds so easy – “One takes care of oneself.” But it involves a lot. It obviously is easy in these times and age to gain a lot of pounds as we are getting older. Some folks even seem to think that aging itself puts pounds on the scale, so “normal” is it to gain weight with every additional birthday. Similar to what we physicians thought about blood pressure: It was “normal” to have higher blood pressure with higher age. So normal actually that physicians had a formula for it: 100+age, the systolic blood pressure was to be. It turned out it was only “normal” in a statistical sense: Most older people had indeed higher blood pressure. But not “normal” in a healthy sense: Healthy people should stay around 120 over 80 – no gain with age. High blood pressure hurts the heart and the arteries, the brain and the kidneys – nothing “normal” in it.
The same goes with weight. In some Asian cultures, the grandparents helped with raising the children, but they tried not to be a burden on the families. They voluntarily ate less. Because the thinking was older people need less food. I am not sure they need less food if they are still active. But in those Asian cultures it was “normal” that older folks got skinny.
Presently, we hear much about self-reliance and self-care. It doesn’t come out of the blue. It comes from bad economic times and the realization that overweight, obese people not only eat more than they need, they also gobble up a bigger share of health care costs.
Taking care of oneself should not take the form of starving oneself – which is never healthy. But to make oneself knowledgeable about which foods pack on the pounds and leave us with a ravenous appetite right after we have eaten might be a way to go. It is easy to blame advertisements, the food industry, indulgent parents, or what not. But in the end it comes down to ourselves who make the decisions.
One doesn’t wake up one morning, and all of a sudden, with no forewarning, one has gained fifty or more pounds. It is a daily process, and we should look at our face in the bathroom mirror and should take a long look at what the bathroom scale shows. We harvest what we sow. The natural laws apply to all of us – no one is exempt. That’s what the French lady wanted to say, I guess.
Society has ways of dealing with people who can’t care for themselves: We are caring for the very young and for the very old, and usually that caring is fairly benign. We also put people in mental institutions and, in extreme cases, in jail if they can’t care for themselves. When States want to make laws restricting sugary drinks or forbidding smoking in public places, there usually is an outcry that rights are taken away. To me, who always was deathly afraid that somebody might take over my life and make decisions for me, it only seems consequent that laws have to take over personal responsibility in certain situations.
One doesn’t let oneself go. One shouldn’t be the problem but the solution to the problem. One takes care of oneself. Read More
Varicose Veins - Phlebitis - Thrombosis
July 29, 2011
Varicose veins are thought to be ugly, and in a way, they are. But as a doctor, I am less concerned with beauty, more with health problems – and varicose veins are not always as harmless as they seem.
Thrombosis is a clot that blocks a vein, usually in one leg. Thrombosis may lead to pulmonary embolus and, in rare cases, to a stroke; both can be fatal. The symptoms are swelling and pain and warmth of the affected limb. Physicians order a Doppler scan, to make sure the patient does not have the feared clotting situation. If it is a clot, the patient will be admitted to a hospital and a severe thinning of the blood will be administered with heparin, Coumadin and other anti-coagulants, until the clot is gone or at least stabilized.
Often the Doppler test comes back negative – no clot, good news! The patient has “only” phlebitis, an inflammation of the wall of a vein. The symptoms are exactly the same: pain, swelling, warmth. In German phlebitis is generally called “cramping veins” because cramps are also a feature of phlebitis/thrombosis. What can you do against inflamed veins?
Phlebitis and thrombosis can have several causes, sometimes combined: A genetic disposition plays a role. Longtime immobility - like sitting on a long trans-Atlantic flight without getting up, or being bed-ridden, especially after surgery – is known to cause clots. Hormone therapy can lead to clotting. Less well known reasons are cancer and food sensitivities, or even just plain food that is not healthy.
Nutrition that is less than optimal is known to promote inflammation. That inflammation can show up as different diseases in the body; one is phlebitis/thrombosis. Junk foods with high sugar content, white starches, trans-fats and particularly dairy are highly inflammatory for everybody. Food sensitivities, on the other hand, specific for individuals, can also inflame, but the causative foods are sometimes hard to pinpoint. I have seen reactions to banana, avocado, nuts, beef (it might be more what the cattle ate than the cows themselves) and cherries – but there are endless possibilities; a food diary might help in recurrent cases.
Varicose veins frequently occur in people with unrecognized gluten intolerance. Slowly, over the years, the varicosities grow, which is often thought as being just another sign of aging. However, varicosities can be viewed as a sign of chronic inflammation of the body. Pregnancies and much standing can aggravate the condition.
What to do in phlebitis:
1. Eliminate all offending foods.
2. Move moderately every day. Don’t sit for prolonged times. Go for a walk every day.
3. Don’t sit with legs crossed – that clamps down of the veinous blood flow.
4. Elevate legs as often as possible.
5. High-dosed fish oil, three capsules three times a day. Fish oil is a mild blood thinner (and could be contra-advised in some conditions) and a strong anti-inflammatory agent.
6. Cold washings and gushes of the legs, cold sitzbaths and barefoot walking in the ocean all are beneficial.
7. In the acute situation, an icepack (not longer than 16 minutes at a time) might bring relief.
8. Wear support panty hose. It prevents the veins to bulge out bigger and bigger. On very hot days cut out the crotch of the panty hose. Wear the support hose also after you are better.
9. Don’t rush into surgery. Phlebitis is often not just a mechanical problem – think about the food connection first.
10. If symptoms get worse with fish oil therapy, you better return to your physician – soon! Read More
