Dr. Jack Kruse Explains the Importance of Sunlight Vitamin D for Health

Of all the health secrets, one of the most sought-after is how to optimize our health, and a common question is why health and healing have to be so complicated. But perhaps it doesn’t.

Neurosurgeon Dr. Jack Kruse carries a simple message to think about how exposure to sunlight has gotten a bad rap over the past few decades and how our relationship to the sun is the key to staying well and energized.

Dr. Kruse says we seem to have forgotten that the sunlight’s system of photosynthesis supports most of the food chain on this planet. And, since our skin is derived from neuroectoderm (cellular structures associated with the brain and nervous system) we rely on the sun for photosynthesis to make vitamin D to protect our health. Vitamin D is too often overlooked by modern medicine in its role to keep us alive and healthy. Maybe, suggests Kruse, we need to rethink our position on Vitamin D and how we produce it.

Let There Be Light

In a recent interview, Dr. Kruse tells Regina Meredith that too many of us are continually exposed to artificial indoor light, causing us to miss out on vital factors required to boost the immune system and allow it to work optimally. Our bodies require the full spectrum of the sun’s rays to produce vitamin D, a hormone naturally created in our skin cells and used for myriad biochemical processes.

The Mayo Clinic explains that vitamin D is needed to regulate many cellular functions in the body and acts to support anti-inflammatory responses, antioxidant activity, nerve cells, the immune system, muscle function, and brain cell activity. Beyond this, explains Dr. Kruse, vitamin D is helpful in warding off viruses and bacteria, and helping the cells efficiently create and use energy.

Vitamin D is an overlooked nutrient, especially in northern climates where sunlight can be scarce for months at a time. Kruse links a number of health issues with vitamin D deficiency, including obesity, bone malformation, psoriasis, heart failure in the newly born, osteoporosis, cardiovascular disease, arthritis, mental illness, diabetes, and even cancer, as well as most autoimmune diseases. Much of these health issues may be attributed to what Dr. Kruse calls a “quantum-biological problem,” meaning that it’s a story about sunlight and our relationship to it. 

A fact of nature is that skin color, as well as other personal health factors, influences how much sunlight we need, which determines our state of health, the efficiency of the immune system, and the production of energy in our cells. People with darker skin need more sunlight than those with lighter skin to produce vitamin D. It’s not a racial problem, says Kruse, but rather a biological issue, despite how media may misinterpret it and how some physicians can misunderstand or overlook this fact. We have to be aware of our skin type and gauge our exposure to the sun accordingly, to glean the benefits of good health and to ward off a host of illnesses.

Powering Up Your Cells

Each cell in our bodies contains an energy-producing powerhouse called the mitochondria. Dr. Kruse explains that mitochondria need fuel from sunlight to produce basic electrical charges. And without enough vitamin D to produce sufficient electricity in the cells, the body cannot protect itself from myriad illnesses. So, explains Kruse, people with darker skin, those who spend too much time indoors, people who tend to be overweight, and other groups may lack the electrical energy needed to remain healthy. The cure is to maximize natural light and the intake of plenty of water while minimizing artificial light.

In “Sun: Full Spectrum Healing,” Dr. Kruse explains how sunshine provides “infrared A light,” the most important factor needed for the health of the mitochondria because it’s the only frequency of natural sunlight that can penetrate deeply enough into our bodies. However, glass—like that in your office, car, or home—blocks out 40 to 60 percent of this all-important light frequency. Once the sun’s “infrared A light” reaches the cells of your body, it helps repair or gets rid of damaged cells. This natural process of cellular death (apoptosis) and turnover (autophagy) boosts the immune system, creates T-cells to fight disease, and produces antigens to trigger the immune response. 

Wake Up and Smell the Sunshine

Dr. Kruse offers a wake-up call and warns us that we should be thinking of sunlight as more of a friend than the enemy so many physicians have painted. “It is beyond me why the sun is so vilified,” writes Kruse. “We could not have evolved past single-celled organisms without it. We all learned that simple fact in school. But now with our advanced degrees and plaques on our wall, are we going to blame all skin diseases all on the sun?” 

Since we are biological beings wholly dependent upon our one and only sun, it’s incumbent upon us to let it nurture our mind, bodies, and environment, and find a way to bathe in the outdoor light. 

You Can Rewire Your Brain to Eliminate Chronic Back Pain

PRT Chronic Back Pain Relief

A groundbreaking new study shows the remarkable efficacy of a brain-based treatment for chronic back pain. It provides new hope for a debilitating problem.

One in five Americans suffers from chronic pain, most often without receiving many benefits from invasive and costly treatments.

The most common type of chronic pain is chronic back pain- in 85% of cases of which no physical cause can be identified.

Dr. Yoni Ashar is a clinical psychologist and neuroscientist who studies psychological treatments for chronic pain. He recently led a study at the University of Colorado Boulder to determine whether a psychological treatment can eliminate chronic back pain — something no other therapy has ever before been scientifically proven to do.

“Our society predominantly thinks about chronic pain through a biomechanical, medical perspective. The most common treatments are physical; they’re injections or physical therapy, something targeting the body. What we’re learning more and more is that in many cases of chronic pain the problem lies in the mind or the brain. And we now have decades of research, both in neuroscience medicine and psychology, showing that there are a lot of changes that happen in the brain during chronic pain. In many cases, these can cause the pain to persist after an injury has healed.”

An important distinction that should be made when discussing chronic pain is that between the two types — primary and secondary.

“With secondary chronic pain, the pain is secondary to some medical problem or disease. With primary pain the pain is the primary problem, it is not secondary to anything else. What really is driving it are neuroplastic changes in the brain, and fear and avoidance. Fear is at the heart of chronic pain, so pain is a danger signal. The fundamental function of pain is to guide a person or animal away from things that are dangerous and when we perceive things to be dangerous that can amplify or even create this pain in our brains.”
