![]() Oral or intramuscular vitamin D supplementation should be considered for those whose levels remain suboptimal. These levels are lower and the difference is statistically significant (p<0.0004) than those of the general British population from a recent national survey, but similar to those in patients with other chronic conditions.Ĭonclusions: This data supports the recommendation made in recent NICE guidelines that all patients with moderate to severe CFS should be encouraged to obtain adequate sun exposure and eat foods high in vitamin D. To get an optimal vitamin D supplement from the sun at a minimal risk of getting cutaneous malignant melanoma (CMM), the best time of sun exposure is noon. Results: 25-OH vitamin D levels are moderately to severely suboptimal in CFS patients, with a mean of 44.4 nmol/L (optimal levels >75 nmol/L). We compared this to a group of patients attending the hospital for other chronic conditions and to a large British longitudinal survey of 45-year old women, using a variety of appropriate statistical approaches. If you expose yourself to the midday sun without sunscreen, yes, you can get your blood level of vitamin D quite high but I don’t think the trade-off is good, says JoAnn Manson, M.D., a professor of medicine at Harvard Medical School and chief of preventive medicine at Brigham and Women’s Hospital in Boston. Subjects and Methods: We performed a retrospective survey of serum 25-OH vitamin D levels in 221 CFS patients. Children are more likely to develop skin cancer from sunburns. Don’t expose yourself to the sun in winter or at higher altitudes. Which time sunlight is harmful The sun’s rays are strongest in the morning and afternoon. If the shadow cast by your body is the same length, or longer, than your height you will not produce Vitamin Deven while your skin is exposed to direct sunlight. Is morning sunlight good for vitamin D Exposure to sunlight after 10 am can be harmful to the body. We hypothesised that serum 25-OH vitamin D levels are lower in CFS patients than in the general British population. A good way to test if the sun is about 50 degrees above the horizon, or higher, is that your shadow should be slightly shorter than you are tall. Introduction: Patients with chronic fatigue syndrome (CFS) may be at risk of osteoporosis due to their relative lack of physical activity and excessive time spent indoors, leading to reduced vitamin D synthesis.
