The Role of Ultra-Weak UV Light in Histidine pathways
One of the most fascinating aspects of our biology is how our bodies interact with and omit light. The light we produce within our bodies are tiny particles known as biophotons and they are produced by cells during metabolic processes.
In this post I will aim to simplify the information on our ability to produce a particular spectra of light called ultra-weak ultra violet (UV) light and its potential role in histamine metabolism and mast cell activation syndrome, but first I will introduce you to the concept of biophotons.
What are Biophotons
Biophotons are tiny particles of light that are emitted by our cells during normal metabolic activities. They are produced in extremely small quantities, and their spectrum can include various types of light, including visible light, infrared, and even ultra-weak UV light.
Biophotons are thought to play a key role in several important bodily functions. One of their main functions is cell-to-cell communication, where they help cells transmit information, ensuring processes across different tissues work in harmony. They are also believed to aid in DNA repair, where biophoton signals may trigger mechanisms to fix damaged DNA, maintaining genetic health.
Additionally, biophotons are thought to regulate circadian rhythms by influencing how cells respond to light and dark, helping the body stay aligned with natural day-night cycles. Their role extends to the immune system potentially helping coordinate immune responses to detect infections and inflammation more efficiently.
One of the most fascinating aspects of biophoton activity is their potential influence on microbiome signalling, shaping how the body interacts with the microorganisms in the gut. This interaction could have significant effects on digestion, immune function, and overall health. Although research is still in its early stages, biophotons are increasingly being recognised as a crucial component in how the body communicates, repairs, and regulates its essential functions.
How is UV Light Produced in Humans?
Although UV light is often associated with the sun, research suggests that our bodies may produce ultra-weak UV light through biophoton emission during certain cellular processes. This light is thought to come from the mitochondria, the components of our cells that are described as generating energy. When our cells carry out oxidative reactions, such as breaking down molecules for energy, small amounts of UV light may be released as a byproduct.
In the context of molecules like histidine or urocanic acid, which I will explain about soon, they have to ability to absorb energy from light or undergo certain chemical reactions, to release biophotons. This process helps cells communicate with each other and may play a role in regulating important functions such as histamine metabolism.
Histidine: The UV-Responsive Amino Acid
Histidine which can be enzymatically converted to histamine, is an aromatic amino acid obtained from the protein we consume though the diet, plays a crucial role in this light-emitting process. Aromatic amino acids like histidine have a unique structure that allows them to absorb and respond to UV light. Specifically, histidine contains an imidazole ring, a structure that is reactive to UV radiation. When exposed to UV light, histidine can absorb this energy and potentially influence cellular processes, including those involved in histamine metabolism.
Histamine Metabolism and UV Light
The metabolism of histamine, is also likely influenced by UV light, primarily due to the presence of the imidazole ring within its structure, and many of the downstream metabolites. This suggests that the processes involved in histamine metabolism could be modulated by UV light.
In addition to its role in histamine production, the aromatic amino acid histidine can also be enzymatically converted into urocanic acid, a compound that plays several vital functions in the skin. Urocanic acid not only absorbs UV light—acting as a natural UV filter for the skin—but also helps moisturise and regulate its immune function. This regulation is particularly important, as it helps maintain the skin's barrier against pathogens and environmental stressors.
The metabolism of urocanic acid is quite intriguing, because it eventually converts into alpha-ketoglutarate, a key player in the Krebs cycle. Alpha-ketoglutarate functions as a non-enzymatic antioxidant, which helps reduce hydrogen peroxide (H2O2) into succinate, water, and oxygen. This process is essential for cellular health and energy production, and also triggers the release of biophotons, including in the ultra weak UV spectrum,
However, if there are disruptions in the metabolism of urocanic acid—especially in people who lack UV light—it could lead to an accumulation of histamine in the body, contributing to skin manifestations such as rashes, redness, and inflammation. As urocanic acid struggles to effectively regulate the skin's immune response due to insufficient UV absorption or production, the skin may become more reactive, leading to heightened sensitivity and a range of symptoms.
The triple role of histidine—as both a UV-responsive molecule, a UV protector and an ultra weak UV light producer—suggests that light in the form of external UV light and internal ultra weak UV biophotons, play a significant role in how the body manages and responds to histamine and it is likely that nature over medications and supplements hold the key to optimising this intricate pathway.
How this knowledge is helping my clients
As histamine reactivity increases, individuals often experience heightened sensitivity to light, heat, and sound. These reactions not only cause discomfort but can also create anxiety around minor environmental changes. This can lead to a simplified, more isolated lifestyle and further disconnection from the vital elements that promote well-being, such as sunlight, fresh air, grounding, and water.
By the time clients reach out to me, they are usually already taking the multiple anti-histamine medications and supplements and are on restricted diets. At this point, I focus on optimising foundational aspects of health, particularly reconnecting them with natural light rhythms.
Even those who are extremely sensitive can usually tolerate the soft light of sunrises and sunsets. This natural light is low in intensity and rich in red and infrared wavelengths, which can help regulate circadian rhythms, reduce inflammation, and promote overall cellular health. Viewing this gentle light—even if it is just through an open window—can help restore some balance to the body, even when being outside is not yet possible.
Balancing Artificial and Natural Light
I frequently discuss, both on social media and in podcasts, the importance of balancing exposure to artificial and natural light. Many people don’t realise how artificial lighting, particularly in the evening and at night, can disrupt their health, so simple strategies such as a digital and artificial light detox can have profound and very quick beneficial effects on health.
A number of my clients also come to me with electromagnetic hypersensitivity (EHS), a condition that is recognised by the World Health Organisation (WHO). EHS can be exacerbated by constant exposure to non-native electromagnetic fields (EMFs) from devices like smartphones, Wi-Fi, and modern lighting systems and is a collection of symptoms of a life spent indoors, that mimics many of the chronic illnesses that we see today. In my opinion non native EMF exposure is one of the key drivers of mast cell activation syndrome.

Quoted from WHO website:
The symptoms (of EHS) most commonly experienced include dermatological symptoms (redness, tingling, and burning sensations) as well as neurasthenic and vegetative symptoms (fatigue, tiredness, concentration difficulties, dizziness, nausea, heart palpitation, and digestive disturbances). The collection of symptoms is not part of any recognised syndrome. EHS resembles multiple chemical sensitivities (MCS), another disorder associated with low-level environmental exposures to chemicals. Both EHS and MCS are characterized by a range of non-specific symptoms that lack apparent toxicological or physiological basis or independent verification.
One of the most effective ways that I found to counteract these effects is through grounding—spending time in direct contact with the Earth and with the natural environment, which helps discharge accumulated non native electromagnetic energy and restores the body’s natural bioelectrical balance. Combining grounding with mindful natural light exposure is a simple yet powerful way to reset the body’s rhythms, without drastic lifestyle changes.

Conclusion: The Quantum Connection
The interaction between UV light, histidine, and histamine metabolism offers a compelling quantum explanation for some of the complexities of MCAS. By understanding how our bodies produce ultra-weak UV light and how key molecules like histidine, histamine and urocanic acid may respond to it, we can begin to view MCAS in a new way—both literally and figuratively.
This quantum perspective not only deepens our understanding of MCAS but also opens new possibilities for managing the condition. By optimising light exposure and considering the role of UV-reactive molecules, we may discover new ways to calm mast cells and reduce the symptoms of this challenging condition.
A holistic approach, grounded in quantum biology, I believe is the key to unlocking better health for those living with MCAS.
