Welcome back to our weekly edition of Friday Field Notes.
This week inside our Doctor of Natural Medicine program, we explore the therapeutic foundations of Phototherapy—also known as light therapy.
Phototherapy refers to the use of specific wavelengths of light to promote healing, regulate biological function, and support the body’s natural restorative processes.
This may include exposure to natural sunlight through heliotherapy, or the use of targeted artificial light designed to mimic specific therapeutic properties of sunlight itself.
Light interacts with the body in profound ways, influencing cellular energy production, hormone regulation, circadian rhythm, mood, immune response, inflammation, and recovery.
Different wavelengths produce different biological effects, which is why various forms of phototherapy are now used across dermatology, mental health, sleep medicine, pain management, and cellular recovery therapies.
Within the holistic and natural medicine space, light is understood as more than simple illumination—it is biological communication.
In our Doctor of Natural Medicine program, students learn the history, science, and therapeutic applications of heliotherapy and phototherapy through both traditional and modern healing perspectives.
Read on to explore various forms of light medicine. 👇🏼 |

| ☀️ Heliotherapy (Sun Therapy)
Heliotherapy utilizes controlled natural sunlight exposure to support physiological balance and overall wellbeing.
Sunlight plays a direct role in regulating multiple biological systems throughout the body.
- Vitamin D synthesis — Supports immune function, bone health, and mineral regulation
- Circadian rhythm support — Helps regulate healthy sleep and wake cycles
- Mood regulation — Natural light exposure influences serotonin and emotional wellbeing
- Circulatory support — Sun exposure may help enhance circulation and vitality
- Seasonal balance — Often utilized to support seasonal mood and energy fluctuations
Pro tip: ditch the sunglasses—our bodies make natural melanin to protect against the harmful rays when our eyes are bare 😎 |

| ❣️🌀 Red, NIR + Blue Light Therapy
Red and near-infrared (NIR) wavelengths are commonly utilized to support tissue repair, mitochondrial function, and recovery processes.
Whereas blue light is often used for surface-level skin and bacterial support.
- Cellular energy support — Red and near-infrared light help stimulate mitochondrial ATP production
- Recovery + restoration — Commonly utilized for tissue repair, muscle recovery, and skin rejuvenation
- Inflammation support — Light therapy may help reduce oxidative stress and support recovery responses
- Blue light applications — Often used therapeutically for acne support and newborn jaundice treatment
- Collagen + skin support — Red wavelengths are associated with collagen production and wound recovery
- Deep tissue penetration — Near-infrared wavelengths reach beneath the skin’s surface to support deeper structures

| 💡 Other Therapeutic Light Modalities
Phototherapy includes a wide range of light-based applications, with different wavelengths influencing the body in unique ways depending on frequency, depth, and therapeutic purpose.
- UV light therapy — Controlled UVA and UVB exposure are used therapeutically for psoriasis, eczema, and vitiligo
- Full-spectrum light therapy — Mimics natural daylight to support mood, serotonin balance, and circadian rhythm
- Cold laser therapy — Low-level laser applications are used for tissue repair, circulation, and neural support
- Purple light therapy — Combines blue and red wavelengths to support both acne reduction and skin rejuvenation
- Nur light therapy — Utilized symbolically in wellness spaces to represent healing, illumination, and restorative light-based therapies
🤍 Light has always shaped human biology, consciousness, rhythm, and restoration.
