Kidney and Heart Disease both respond to Sun (UV) Therapy.

By Marc Sorenson, EdD.  Sunlight Institute…

In end stage kidney disease, heart disease and other vascular diseases are often the most dreadful accompanying disorders, also known as a comorbidities. Any healthful procedure that can mitigate the distress of these diseases can be a godsend to the patient suffering from kidney deterioration. UV therapy, similar to sun exposure, has now been shown to alleviate some of the difficulties of cardiovascular diseases and thereby increase the quality of life.[1]

The research was conducted on fourteen kidney-dialysis patients. They were irradiated with whole-body UV for six months. Before and after that time, they were measured for several physiological functions to determine if there had been worthwhile changes in indicators of cardiovascular diseases. These were the results:

  1. Hematocrit increased, indicating a larger volume of red blood cells, which are important for carrying oxygen to the heart, vessels and all other parts of the body.
  2. The patients required less erythropoietin, a hormone that stimulates production of red blood cells and hemoglobin in case of low-tissue oxygen. This would indicate that oxygen need was reduced after the UV treatment, putting less stress on the cardiovascular system.
  3. In addition to, or perhaps because of, these positive changes, maximal oxygen uptake increased, indicating greater work capacity and physical fitness.
  4. Workload capacity increased and lactic acid production decreased, also indicative of enhanced physical fitness.
  5. Pulse rate decreased, indicative of an ability of the heart to deliver more oxygen per beat through the cardiovascular system. This is also a fitness measurement.
  6. Both systolic and diastolic blood pressures decreased, showing a healthier vascular system.

The researchers made the following conclusion: “Cardiovascular disease is the most important comorbidity [to kidney disease]. Exposure to simulated sunlight that contains both UVB and UVA reduce cardiovascular risk factors and improve quality of life.”

Protect your kidneys or protect your heart either by safe exposure to the “simulated sunlight” of sunlamps or tanning devices, or by regularly exposing yourself (again, safely) to mankind’s best friend the Sun.
