Healing 101(b)(i)
Seriously, sometimes it is simple...sunshine, good food, rest and play. And companionship. So today I will again bore people with my take on optimal sun. Wow. this is seriously a new low.
as an aside, I went to my Dad's for Thanksgiving. It was the first holiday with him in which I did not have to concern myself with feeling off. THat was, itself, a pleasure. It is sometimes like I have rewound the past. It was so long that I could not connect with the people I love and the people with whom I was spending time. It is an endless joy just to be with them, and to laugh, and be bored, and just be.
Sun.
When I was young, parents sent thier kids to play in the sun. Now, kids are slathered in sun screen and kept indoors. Everyone wears sunscreen so that even when you are in the sun, you are not in the sun. SEE Caryl A Nowson and Claire Margerison (2002). "Vitamin D intake and vitamin D status of Australians". The Medical Journal of Australia 177 (3): 149–152. PMID 12149085.
I played sports. I swam and I played water polo. I surf. I spent so many long hours in the sun, exposing almost every inch of my body to the sun, that I grew concerned when mainstream health media began to tell me that what I had done was damaging and potentionally increased by tendency to certain cancers.
I will not bore you with my research, or my journey thROugh it, and my many opinions. I will tell you my conclusion now.
Regular exposure to the sun is necessary to wellness. Exposure to sun is good, but trauma is bad.
Vitamin D From Sunlight
The ultraviolet wavelength that stimulates our bodies to produce vitamin D is UV-B. It is sometimes called the "burning ray" because it is the primary cause of sunburn. However, UV-B also initiates the beneficial responses, stimulating the production of vitamin D that the body uses in many important processes. Although UV-B causes sunburn, it also causes special skin cells called melanocytes to produce melanin, which is protective. UV-B also stimulates the production of Melanocyte Stimulating Hormone (MSH), an important hormone in weight loss and energy production.
It is difficult to get adequate vitamin D from sunlight because while UV-A is present throughout the day, the amount of UV-B present has to do with the angle of the sun's rays. Thus, UV-B is present only during midday hours at higher latitudes, and only with significant intensity in temperate or tropical latitudes. Only 5 percent of the UV-B light range goes through glass and it does not penetrate clouds, smog or fog. Sun exposure at higher latitudes before 10 am or after 2 pm will cause burning from UV-A before it will supply adequate vitamin D from UV-B. It means that sunning must occur between the hours we have been told to avoid. Only sunning between 10 am and 2 pm during summer months (or winter months in southern latitudes) for 20-120 minutes, depending on skin type and color, will form adequate vitamin D before burning occurs.
The current suggested exposure of hands, face and arms for 10-20 minutes, three times a week, provides only 200-400 IU of vitamin D each time or an average of 100-200 IU per day during the summer months. In order to achieve optimal levels of vitamin D, 85 percent of body surface needs exposure to prime midday sun. (About 100-200 IU of vitamin D is produced for each 5 percent of body surface exposed, we want 4,000 iu.) Light skinned people need 10-20 minutes of exposure while dark skinned people need 90-120 minutes. Latitude and altitude determine the intensity of UV light. UV-B is stronger at higher altitudes. Latitudes higher than 30° (both north and south) have insufficient UV-B sunlight two to six months of the year, even at midday.12 Latitudes higher than 40° have insufficient sunlight to achieve optimum levels of D during six to eight months of the year. In much of the US, which is between 30° and 45° latitude, six months or more during each year have insufficient UV-B sunlight to produce optimal D levels. In far northern or southern locations, latitudes 45° and higher, even summer sun is too weak to provide optimum levels of vitamin D.
So I live in Boston, which lies at just above 42 degrees norhtern latitude. That means that if I suddenly decided to lie stark naked in the commons at 12 noon tommorrow, I would not revieve sufficeint UVB to give me the needed vitamin D for my system. While I have no immediate plans for public nudity nor exposure to the sun in 35 degree weather, the fact remains, I am not getting enough Vitamin D during the winter, and, as an office bound attorney, probably not in the summer either.
So what am I missing?
Your buddy Vitamin D:
"Sunlight and vitamin D are critical. Standard textbooks state that the principal function of vitamin D is to promote calcium absorption in the gut and calcium transfer across cell membranes, thus contributing to strong bones and a calm, contented nervous system. It is also well recognized that vitamin D aids in the absorption of magnesium, iron and zinc, as well as calcium.
Receptors for vitamin D are found in most of the cells in the body and research during the 1980s suggested that vitamin D contributed to a healthy immune system, promoted muscle strength, regulated the maturation process and contributed to hormone production.
During the last ten years, researchers have made a number of exciting discoveries about vitamin D. They have ascertained, for example, that vitamin D is an antioxidant that is a more effective antioxidant than vitamin E in reducing lipid peroxidation and increasing enzymes that protect against oxidation.19;20
Vitamin D deficiency decreases biosynthesis and release of insulin.21 Glucose intolerance has been inversely associated with the concentration of vitamin D in the blood. Thus, vitamin D may protect against both Type I and Type II diabetes.22
The risk of senile cataract is reduced in persons with optimal levels of D and carotenoids.23
PCOS (Polycystic Ovarian Syndrome) has been corrected by supplementation of D and calcium.24
Vitamin D plays a role in regulation of both the "infectious" immune system and the "inflammatory" immune system.25
Low vitamin D is associated with several autoimmune diseases including multiple sclerosis, Sjogren's Syndrome, rheumatoid arthritis, thyroiditis and Crohn's disease.26;27
Osteoporosis is strongly associated with low vitamin D. Postmenopausal women with osteoporosis respond favorably (and rapidly) to higher levels of D plus calcium and magnesium.28
D deficiency has been mistaken for fibromyalgia, chronic fatigue or peripheral neuropathy.1;28-30
Infertility is associated with low vitamin D.31 Vitamin D supports production of estrogen in men and women.32 PMS has been completely reversed by addition of calcium, magnesium and vitamin D.33 Menstrual migraine is associated with low levels of vitamin D and calcium.81
Breast, prostate, skin and colon cancer have a strong association with low levels of D and lack of sunlight.34-38
Activated vitamin D in the adrenal gland regulates tyrosine hydroxylase, the rate limiting enzyme necessary for the production of dopamine, epinephrine and norepinephrine. Low D may contribute to chronic fatigue and depression.39
Seasonal Affective Disorder has been treated successfully with vitamin D. In a recent study covering 30 days of treatment comparing vitamin D supplementation with two-hour daily use of light boxes, depression completely resolved in the D group but not in the light box group.40
High stress may increase the need for vitamin D or UV-B sunlight and calcium.41
People with Parkinsons and Alzheimers have been found to have lower levels of vitamin D.42;43
Low levels of D, and perhaps calcium, in a pregnant mother and later in the child may be the contributing cause of "crooked teeth" and myopia. When these conditions are found in succeeding generations it means the genetics require higher levels of one or both nutrients to optimize health.44-47
Behavior and learning disorders respond well to D and/or calcium combined with an adequate diet and trace minerals.48;49"
So what do I do?
Well, I try to get into the sun. That means biking to work in the summer, I take as many sun walks as I can, and I try to get out into it on the weekend. I avoid burning. The strongest cancer links are found in those who regulalry burn, or who have burned traumatically, or who have burned before the age of 12. People who have regular exposure to sunshine do not have extremely elevated risk of skin cancer. It is the Summer and weekend burn sets that are most in danger.
I stopped wearing sunglasses as often as I used to. Apparently some of the conversion process from pro-hormone to hormone only occurs in the cornea is stimulated directly with sunshine. Beisdes that, I like the sun. I like the way it feels. I like spring time sun naps, and the way it warms the summer concrete around the pool.
I wear sun screen when I surf. I try to get into the sun for a bit before I put it on. I put a lot of it on my face. I am looking into UV googles for the ocean because I made a very stupid mistake when I was playing polo and burned my retina when I was in college. I have a cateract now for my indescretion, and it is not a process I am long to accelerate.
I have considered buying a sun lamp. Sperti makes the best ones. I dont know much more about it, though I do have fantastic images of sun lamp driven bikini pool parties this winter in Boston. Hey, they make fake snow, why not fake sun?
I take cod liver oil. It is the foundation of all my other supplments. I take a teaspoon every day with my morning nutrients. It tastes, well, like fish oil. But they do make flavored oils. It was my experience that my nutrients were absorbed better with it. Amount of nutrient prescribed by the PTC all of a sudden were a bit too much. I am thinking of vitamin b-6 in particular. Its good, cheap insurance, and if I had only one supplement in my chest, that would be it.
here is a bit on it:
"This marvelous golden oil contains large amounts of elongated omega-3 fatty acids, preformed vitamin A and the sunlight vitamin D, essential nutrients that are hard to obtain in sufficient amounts in the modern diet. Samples may also naturally contain small amounts of the important bone- and blood-maintainer vitamin K.
There is hardly a disease in the books that does not respond well to treatment that includes cod liver oil, and not just infectious diseases but also chronic modern diseases like heart disease and cancer. Cod liver oil provides vitamin D that helps build strong bones in children and helps prevent osteoporosis in adults. The fatty acids in cod liver oil are also very important for the development of the brain and nervous system. "If you want to prevent learning disabilities in your children," said David Horrobin, distinguished medical and biochemical researcher, "feed them cod liver oil."Cod liver oil contains more vitamin A and more vitamin D per unit weight than any other common food. One hundred grams of regular cod liver oil provides 100,000 IU of vitamin A, almost three times more than beef liver, the next richest source; and 10,000 IU vitamin D, almost four times more than lard, the next richest source. Of course, cod liver oil is only consumed in small amounts, but even a tablespoon (about 15 grams) provides well over the recommended daily allowance for both nutrients.
In addition, cod liveroil contains 7 percent each of the elongated omega-3 fatty acids EPA and DHA. EPA is the precursor of important prostaglandins, localized tissue hormones that help the body deal with inflammation; and DHA is extremely important for the development and function of the brain and nervous system. So it's no surprise that in numerous studies cod liver oil has proven to be a powerhouse in fighting disease."
