Study Confirms: UV From Tanning Lowers Blood Pressure
According to research published in the Journal of Investigative Dermatology,
when UV rays reach the skin, a compound that helps lower blood pressure is
released into our blood vessels.
The Researchers At The University Of Edinburgh In The Uk Postulate That
The Cardiovascular Benefits Of Vitamin D May Outweigh The Risks Of Skin Cancer.
The researchers recruited 24 volunteers to sit under sunlamps for two 20 minute
sessions while the scientists observed their blood pressure. In the first
session, the participants were exposed to UV rays and the heat of the lamp. In
the second session the UV was blocked so only the heat was affecting the skin.
The researchers found that the participants’ blood pressure decreased and their heart rate rose in the UV exposure session,
but not when they were exposed to the heat only. The reduction in blood
pressure lasted for 50 minutes. Vitamin D levels were unaffected in both
Richard Weller, lead author of the research explains, “We suspect that the benefits to heart health of sunlight will outweigh the risk
of skin cancer. The work we have done provides a mechanism that might account
for this, and also explains why dietary vitamin D supplements alone will not be
able to compensate for lack of sunlight.”
The researchers plan to focus future research on the risks of heart disease and
skin cancer in people with different levels of sun exposure. He concludes, “If this confirms that sunlight reduces the death rate from all causes, we will
need to reconsider our advice on sun exposure.”
New Study Finds High Rates Of Vitamin D Deficiency In Kidney Transplant Patients
As reported by The Vitamin D Council (5/14)- Researchers have recently found that vitamin D deficiency is common in
kidney transplant patients in Southern California.
These findings were presented at the National Kidney Foundation’s 2014 Spring Clinical Meeting. This meeting allows for kidney health care
providers to come together and learn about and discuss the latest developments
in various aspects of kidney health. Vitamin D is important in any surgical procedure as higher vitamin D levels can
help decrease the risk of inflammation and infection. Vitamin D deficiency may
increase the risk of the patient’s body rejecting the new kidney after a transplant.
In this new study, researchers from the University of Southern California looked
at the vitamin D levels of 53 patients who had received kidney transplants in
2013. They found that 26 patients had levels between 10 and 20 ng/ml, 17
patients had levels between 20 and 30 ng/ml, and only 9 patients had levels
above 30 ng/ml. “Our initial data suggests that approximately 83 percent of our transplant
populations is vitamin D deficient four weeks after transplantation. These
results were surprising, as most of these patients were taking vitamin D
supplements,” said lead researcher Dr. Rahul Dhawan. “It shows us that we need to be even more aggressive in recognizing and treating
