I am being seriously distracted by the weather. It’s been so nice for the last few days. Like right now. The sun is out (yeah) and I’ve been in front of glass deck doorway soaking it all up like a little cat. My doc tells me to get more vitamin D so that’s what I try to do. I just haven’t figured out a way to lie in the sun and type on a computer yet.
Since I tend to run vitD deficient, I did a little search on how to get more of it without relying on vitD drops. Here is what I learned.
How common is vitamin D deficiency? Common!
Even in southern Arizona, where I live, vitamin D deficiency is common — Dr. Andrew Weil.
There have been concerns about vitamin D status in the U.S. because of increasing reports of deficiencies, with an estimated 10 million Americans over age 50 diagnosed with osteoporosis — Eduardo Baetti, MD.
More than half of all women are thought to be deficient in vitamin D, and the latest evidence from Johns Hopkins University confirms that failing to get enough boosts your risk of death by 26% — Health.com
Okay, so why do we need it?
New research suggests it [vitamin D] may also help protect against chronic diseases such as cancer, type 1 diabetes, rheumatoid arthritis, multiple sclerosis, and autoimmune diseases — Kathleen M. Zelman, MPH, RD, LD
Skip the sunscreen for a bit if your goal is vitD.
Dermatologists have made everyone so paranoid about sun exposure that most people here use sunscreen all the time, and sunscreen blocks vitamin D synthesis — Dr. Andrew Weil.
Southerners are lucky.
People living in the Southern United States can get enough vitamin D by getting about 10-15 minutes of sun exposure on their arms and face a few times a week — Michael Holick, PhD, MD.
Darker skinned people need more rays.
Dark pigment in the skin reduces the skin’s ability to synthesize vitamin D from sunlight by 95%.
If you’re African-American and live in Boston, New York or San Francisco, adequate exposure equals 25 to 35 minutes a day in the sun between the hours of 11 a.m. and 3 p.m., from June through August. After that time, apply sunscreen. — Michael Holick, PhD, MD.
Medium to Fairer complexions should take it easy.
Women who have medium skin tones may need 15 to 20 minutes’ exposure.
If you have a fair complexion, you’ll need just 5 to 10 minutes of sunshine on your arms, legs, or back—without sunscreen (yes, it shuts down the production of D)—between 10 a.m. and 3 p.m. three days a week — Min-Wei Christine Lee, MD, MPH.
And we all worry about skin cancer.
Sensible sun exposure to arms and legs for short periods of time will not increase the risk of serious skin cancer such as melanoma — Michael Holick, PhD, MD.
And you must get enough vitD in the summer.
If you get enough sun exposure in the summer, your body will make and store enough D to get you through the winter.
Overweight people present a special situation.
This [sun exposure in the summer] doesn’t work as well if you’re obese because body fat holds onto vitamin D tenaciously and doesn’t release it efficiently — Dr. Weil
Grandma and grandpa may need extra help.
With advancing age, the skin cannot synthesize vitamin D as efficiently as it once did and the kidneys are less able to convert vitamin D to its active hormone form — Dr. Weil

You may want to try to find this book in a library, The UV Advantage (iBooks, 2003). It has “tables showing how much sun exposure you need for adequate vitamin D synthesis, depending on your skin type, the season of the year, time of day, and where you live.”
