When it comes to understanding human health, Dr. Jack Kruse, a neurosurgeon who’s performed over 10,000 surgeries, encourages us to look beyond traditional medicine and consider natural principles. His interest in light, cellular biology, and melanin (the pigment in our skin) led him on a journey to unravel some of the body’s more mysterious processes, inspired by nature and its 3 legs Light, water and magnetism
The Role of Light and Health
One of Jack’s revelations came while on a trip in Florence viewing Michelangelo’s “David” statue. Observing how sunlight struck David’s chest, something clicked in Jack’s head and he began an 18-month journey in a try to understand light’s role in evolution. His research led him to realize that mammals and birds share a unique feature: both have melanin, a pigment capable of absorbing light across the electromagnetic spectrum. This pigment, according to Jack, was key to the survival of mammals when an asteroid struck Earth 65 million years ago, marking the extinction of dinosaurs.
The Leptin-Melanocortin Pathway – the Connection to Light
Old research on exposing cow eyes for different radiation deepened Jack’s understanding of light’s effect on the body. Jack found papers stating that UV light passes through the eye to reach retinal pigment epithelial cells, rich in melanin. These cells, Jack realized, may act as “fiber-optic cables” conducting light to the brain, potentially affecting the body’s overall health and wellness.
Blue-Light, Circadian Rhythms, and Mitochondria
Mitochondria function as “wideband semiconductors,” a property allowing them to generate energy from light. Exposure to light, especially in the morning, can support mitochondrial health and optimize functions like dopamine production, which is crucial for mood and health.
Jack’s research also highlights the negative effects of blue light (from screens and nonnative light) and AC electricity on human health. Blue light, for instance, can damage the retina and disrupt melanin stored in the substantia nigra in the brain impairing vision and potentially leading to health issues like myopia. He notes that many children, especially those frequently exposed to screens, are developing myopia due to the artificial blue light that interferes with their visual development.
According to Jack, spending time in natural light, especially sunlight rich in red and infrared wavelengths, is vital for maintaining good health. He cautions against overuse of screens and artificial light, advocating for outdoor time and reduced exposure to screens in favor for sunlight.
Melanin
Melanin acts as a screen for light within the body, directing light to the right place and enabling cells to convert light to electric energy inside the body. This concept aligns with the idea of humans as “carbon-based semiconductors,” meaning that our bodies can absorb and utilize light similarly to plants through photosynthesis.
Interestingly, he links the production of melatonin to mitochondria. Melatonin, synthesized in response to light and dark cycles, is critical for maintaining cellular and immune health. Modern exposure to artificial light can hinder natural melatonin production, a factor that Jack associates with increased susceptibility to diseases.

Mammalian Evolution
Melanin, primarily known for its role in skin pigmentation, has been essential for mammals, including humans, as a powerful light-absorbing pigment. It acts as a biological tool for storing and using light in various ways. Melanin’s three main types—eumelanin, pheomelanin, and neuromelanin—each have unique properties based on their chemical structure, which allows for different light absorption and energy storage functions. Interestingly, melanin doesn’t just interact with visible light but absorbs a wide range of frequencies, from VUV, UVA to UVB-light and can protect us from other cosmic radiation, providing a buffer against various environmental stresses.
After the KT-event, the neuroplasticity in mammals—a trait allowing brain cells to adapt and reorganize—was likely stimulated by low light conditions. When UV light was scarce, mammals developed mechanisms to harness internal melanin reserves. Humans, in particular, utilize UV light to regulate cellular functions, influencing everything from skin pigmentation to metabolic processes
The Power of Light and Cold in Human Physiology

Jack explored how exposure to cold and sunlight can enhance human health. Cold exposure has been shown to increase the production of mitochondrial based light within the body, creating cellular energy without sunlight means that the human body can produce energy together with stored melatonin This process occurs because colder environments encourage the mitochondria to emit VUV-light, that drives energy processes within our cells.
A significant finding is that the endolymphatic system in the ear contains calcium chloride, which, in conjunction with potassium, acts as a wide-based semiconductor. This system helps the body process light into cellular energy, interacting with melanin to create internal light. This understanding underscores how the interplay of light, melanin, and temperature shapes biological functions, supporting health and adaptation to environmental changes.
The body is a semiconductor
Water, particularly structured water, plays a vital role in biological energy transfer and storage. Structured water, which has a unique molecular arrangement, has the ability to store and conduct energy more efficiently. Jack found that this special water type is created when sunlight hits water, making it more “quantum coherent.” This structured form of water not only aids in energy transfer within cells but also has a net negative charge, facilitating the migration of light and other signals across cell membranes.
Water’s dual-phase properties make it an ideal medium for cellular communication. It can adapt to different energy states, transitioning between liquid and structured forms to regulate temperature and energy flow within cells. These properties make water integral to photosynthesis and mitochondrial function, allowing cells to efficiently manage energy intake and waste disposal.

Modern Health Implications of Light and Melanin
Today, our environments have dramatically shifted. The prevalence of artificial light, especially blue light from screens and LED lighting, interferes with our natural light-processing mechanisms. Blue light disrupts melatonin production, and destroys the stored melanin in our body. causing body to not communicate properly due to the lack of melatonin the light cannot be distributed the right way causing sleep disorders, and potentially contributing to other major health issues. Kruse points out that, unlike sunlight, blue light lacks the full spectrum of UV and infrared wavelengths necessary for optimal health, which may hinder processes regulated by natural light exposure, including hormone balance and cellular function.
He suggests that grounding, making direct contact with the earth’s surface could improve our body’s electrical efficiency by providing electrons that facilitate the transfer of light energy within cells. Walking barefoot on natural surfaces, particularly wet sand, and grass can increase the body’s electrical charge, enhancing cellular efficiency and supporting melanin’s energy-storing properties.
Nutrition, Melanin, and Modern Diseases
Kruse recommends a keto diet high in fats, with limited carbohydrates, especially later in the day, to better align with our evolutionary energy requirements. He argues that modern dietary habits, coupled with low natural light exposure and high artificial light exposure, disrupt the body’s energy metabolism and lead to diseases linked to mitochondrial dysfunction. This you could link to almost every modern disease out there.

Factbox
Leptin-Melanocortin Pathway: This biological pathway helps regulate energy balance, appetite, and body weight. Leptin, a hormone produced by fat cells, signals the brain to reduce hunger when energy stores are sufficient. The pathway involves the melanocortin system in the hypothalamus, where melanocortin receptors influence satiety and metabolism.
Mitochondria: Known as the cell’s powerhouses, mitochondria are organelles that produce energy in the form of ATP through cellular respiration. They play crucial roles in metabolism, energy production, and regulating cell death.
Melatonin: A hormone produced by the pineal gland in response to darkness, melatonin helps regulate the body’s sleep-wake cycle. It signals to the body that it’s time to sleep and is essential for circadian rhythm regulation.
Mammals: A class of warm-blooded vertebrates characterized by the presence of mammary glands (for feeding young), hair or fur, and, typically, live birth. Mammals include humans, cats, elephants, and dolphins.
KT-event: Short for the Cretaceous-Paleogene (K-Pg) extinction event, the KT-event was a mass extinction around 66 million years ago, likely triggered by a massive asteroid impact. It led to the extinction of many species, including non-avian dinosaurs.
VUV-light: Vacuum ultraviolet light (VUV) is a part of the UV spectrum with wavelengths ranging from 100 to 200 nm.
Endolymphatic System: A fluid-filled system within the inner ear that plays a key role in maintaining balance and hearing. It helps transmit sound vibrations and detects head movements to support balance.
Structured Water: A hypothesized form of water with a specific molecular arrangement, thought to have unique properties that support biological processes. Also called “exclusion zone” (EZ) water, it is believed to form near cell membranes, though its existence and benefits are still debated.
Grounding: Also called “earthing,” grounding involves direct physical contact with the earth (e.g., walking barefoot on soil). It’s thought to balance electrical charge in the body, potentially reducing inflammation and improving well-being, although scientific support is mixed.
This is part of a short summary from a collective appearances That Dr Jack Kruse has made in the public domain and I highly recommend you to continue to collect information about this topic, as you can imagine there is a lot more to it than the info displayed above.
