Sunlight Reduces the Risk of Hip Fracture by 77% in Alzheimer’s, Parkinson’s and Stroke Patients.

Sunlight Reduces the Risk of Hip Fracture by 77% in Alzheimer’s, Parkinson’s and Stroke Patients.

While perusing the medical and scientific literature for research that would be pertinent for my upcoming book on the value of sunlight exposure, I found a most interesting paper on sunlight exposure and bone strength.[i] The researchers searched the literature on three groups of patients, Alzheimer’s, Parkinson’s and Stroke which correlated to very high fracture rates among patients suffering from those diseases. They then found three randomized, controlled studies that determined the efficacy of sunlight exposure for reducing the risk of hip fractures in patients with these diseases.

In each study, there was a control group that did not receive the exposure and an experimental group that received regular sunlight exposure to a small part of the body daily for a year. The results were impressive: For Alzheimer’s patients, the reduction in hip fractures was 78% compared to the controls who stayed inside; for Parkinson’s patients, 73%; for stroke patients, 83%. Overall, the risk of the hip fracture was reduced by 77% in the sunlight exposed groups. Bone mass also increased in each sunlight-exposed group, so osteoporosis was obviously reversed. Did you even realize that such a thing was possible? You probably knew it only if you have been reading the Sunlight Institute blogs. There is an even more impressive study that I always mention when writing about sunlight and osteoporosis. For example, an investigation from Spain in 2008 concluded that women who actively participated in sun exposure had one-eleventh the chance of a hip fracture as those who stayed indoors.[ii] It appears from the materials on the different disease groups mentioned above, that reversibility is a reality, but how much more important is it to prevent the disease in the first place? The women in Spain did exactly that.  

The National Osteoporosis Foundation estimates that osteoporosis was responsible for more than 2 million fractures in 2005, including 297,000 hip fractures, 547,000 vertebral fractures, 397,000 wrist fractures, 135,000 pelvic fractures and 675,000 fractures at other sites. The foundation also estimates that the number of osteoporotic fractures is expected to rise to more than 3,000,000 by 2025, and that an average 24 % of hip-fracture patients aged 50 and over die within one year following the occurrence of their fracture.[iii]  If we take 24% of just the hip fractures that cause death we see that osteoporosis kills at least 71,280 people per year.

Do you believe that it might be worth a daily sunbath to save the lives of 70,000 people per year? Do you believe that it would be worth daily exposure (unprotected by sunscreen) to the sun (when possible) to reduce your own risk of fracture? Then why don’t we know about these statistics and the marvelous prophylactic effects of sunlight? That answers are simple: (1) it doesn’t sell any Fosamax or Boniva. (2) It doesn’t sell any noxious, deadly sunscreens. (3) It would be unthinkable for most dermatologists to admit that soaking up a little sun each day might be good for us. It has been said, “And ye shall know the truth and the truth shall make you free.”[iv] Now you have boned up on bone strength and sunlight, and you know the truth.  

My fervent hope is that all may be free from the deceptions of those who would ignore the truth in favor of making another dollar.
