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

The Role of Your Neck in Urge Incontinence
February 21, 2011
As a physician I sometimes make observations that strike me as plausible – but I don’t have the wherewithal or time to scientifically check on them. Writing a blog might be one method to test an idea, and find out if others made similar observations.
So, here is my first one, pertaining to urge incontinence.
Wikipedia defines urge incontinence as “involuntary loss of urine occurring for no apparent reason while suddenly feeling the need or urge to urinate.” What really happens is the patient makes it to the stall but then goes before she has a chance to pull down her pants. Or she hears water tinkling, and tinkles herself.
The two other forms of urinary incontinence are stress incontinence and overflow incontinence. Stress incontinence comes from weak pelvic floor muscles – when you sneeze or run or laugh, you suddenly can’t hold your urine. Overflow incontinence is a constant dribbling of urine – as if the faucet can’t be shut off. All three forms are common in people of a certain age – therefore the hilarious TV ads for adult diapers. But according to my patients, incontinence is no laughing matter. People thus afflicted (women are in the majority here, probably because of what childbirth can do to one’s organs) are on the constant lookout for the nearest restroom.
The interesting part of Wikipedia’s definition of urge incontinence is “for no apparent reason.” Urge incontinence has been linked to stroke, Alzheimer’s, spina bifida, multiple sclerosis (MS), Parkinson’s – they all can lead to urge incontinence. All are neurogenic causes (stemming from the brain and the nerves) – we lump them in one group, but still they are poorly understood. And then there is “idiopathic” urge incontinence. Idiopathic means: Doctors have no clue at all. But they think it has to do with local inflammation around the bladder.
Years ago a patient with urge incontinence told me that she could make the urge disappear (at least long enough to make it to the bathroom), if she stretched her neck. For a while I was not sure if any sudden distraction – like clapping your hands or hopping up and down – would do the same. But lately I returned to my first hypothesis, namely that the stretching of the neck works best. Because I have observed that the condition occurs more often in people with less than stellar posture, especially the ones whose head is slightly bent most of the time. Standing tall and erect, at least for a moment, seems to release the urge.
As for the mechanism – are certain spinal nerve fibers pinched when the head is bent? We need more research on that.
Poor posture is more common in people with gluten intolerance and food allergies – it seems as if they don’t have the muscular strength to keep their heads straight on their shoulders – perhaps on the basis of poorly functioning mitochondria (this is all speculation on my part; I would be happily disproved).
If urge incontinence is your problem, try this out – nod a bit, stretch your neck - and write me if it works for you! Perhaps one day a peer-reviewed study will be done. Read More
