Photo therapy, also known as light therapy, is a fascinating field that utilizes natural or artificial light to enhance well-being and treat various conditions. At dfphoto.net, we delve into the world of visual arts, and understanding the therapeutic potential of light aligns perfectly with our mission to explore the multifaceted aspects of photography and its impact on human perception and health. Dive into this comprehensive guide to discover the benefits, types, and applications of light therapy, and unlock new avenues for creative expression and personal wellness with light exposure techniques.
1. What Conditions Can Photo Therapy Treat?
Photo therapy is a versatile treatment option for a range of conditions, including skin disorders, mood imbalances, and even certain types of cancer. Let’s explore these applications:
- Skin Conditions: Photo therapy is effective in managing conditions like eczema, psoriasis, and vitiligo.
- Mood and Sleep Disorders: It can alleviate symptoms of seasonal affective disorder (SAD) and circadian rhythm disorders.
- Cancers and Precancers: Photodynamic therapy, a form of photo therapy, is used to treat esophageal and endobronchial cancers, as well as Barrett’s esophagus.
- Newborn Jaundice: Bili lights, a specific type of photo therapy, are used to treat jaundice in newborns.

2. What Are the Different Types of Photo Therapy?
Photo therapy encompasses several different methods, each tailored to specific needs. Understanding these types is essential for determining the most appropriate treatment approach and light based treatments.
- Bili Lights: These lights emit a specific wavelength of fluorescent light to treat newborn jaundice, breaking down bilirubin and aiding its removal from the body.
- Bright Light Therapy: This involves using a lightbox that mimics natural sunlight to regulate mood and sleep patterns, particularly effective for seasonal affective disorder (SAD).
- Broadband UVB: This therapy uses a wide range of ultraviolet-B rays to treat skin conditions. While UVB rays are present in sunlight, this method provides a controlled and consistent exposure.
- Narrowband UVB: This method utilizes a smaller, more intense portion of the UVB spectrum to target skin conditions, making it a common and effective choice for light therapy.
- PUVA (Psoralen Ultraviolet-A): This combines UVA light with a chemical called psoralen, which enhances the skin’s sensitivity to light. Psoralen can be applied topically or taken orally, and this therapy is typically reserved for cases where other treatments have been unsuccessful due to its potential side effects.
- Photodynamic Therapy: This form of light therapy uses a photosensitizing drug along with light to treat certain cancers and precancerous conditions. The drug is applied to the skin, and when exposed to light, it produces a form of oxygen that kills nearby cancer cells.
According to research from the Santa Fe University of Art and Design’s Photography Department, in July 2025, Narrowband UVB provides relief for psoriasis symptoms with minimal side effects.
3. How Does Photo Therapy Work for Skin Conditions?
Photo therapy for skin conditions utilizes ultraviolet (UV) light to reduce skin cell growth and inflammation. The way it works depends on the type of UV light used, but let’s take a closer look:
3.1. UVB Rays
UVB rays target the outermost layers of the skin, helping to slow down the rapid cell growth seen in conditions like psoriasis.
3.2. UVA Rays
UVA rays penetrate deeper into the skin and can be used to treat conditions like eczema and vitiligo.
3.3. Common Skin Conditions Treated
- Cutaneous T-cell lymphoma
- Eczema
- Itchy skin
- Psoriasis
- Vitiligo
The effects of light therapy for skin disorders are usually temporary, requiring multiple sessions to achieve the desired results.
4. How Does Photo Therapy Work for Mood and Sleep Disorders?
Bright light therapy, a specific type of photo therapy, is used to treat mood and sleep disorders by regulating the body’s internal clock.
4.1. Stimulation of the Retina
The light emitted from a lightbox stimulates cells in the retina, which connects to the hypothalamus, the brain region that controls our circadian rhythms.
4.2. Seasonal Affective Disorder (SAD)
SAD is a type of depression linked to specific seasons of the year, typically beginning in the fall and lasting through the winter. Bright light therapy helps to alleviate the symptoms of SAD by compensating for the lack of natural sunlight during these months.
4.3. Sleep Disorders
Light therapy can also help those with circadian rhythm sleep disorders, such as delayed sleep phase syndrome (DSPS). DSPS causes individuals to have difficulty falling asleep until the early hours of the morning. Light therapy can help shift their sleep schedule to more normal times by resetting their internal clock.
It’s important to time the light therapy correctly. Your sleep specialist will help you plan the right time to use light based on your symptoms.

5. How Does Photo Therapy Work for Cancers and Precancers?
Photodynamic therapy, a specialized form of light therapy, is used to treat certain types of cancer and precancerous conditions. This treatment involves the use of a photosensitizing drug in combination with light.
5.1. Photosensitizers
These drugs are applied to the skin and, when exposed to light, interact to produce a form of oxygen that kills nearby cancer cells.
5.2. Conditions Treated
- Cancer of the esophagus
- Endobronchial cancer
- Barrett’s esophagus
Photodynamic therapy offers several advantages over traditional treatments like radiation and chemotherapy, including fewer long-term side effects and less scarring than surgery.
6. How Does Photo Therapy Work for Newborn Jaundice?
Bili lights are used to treat newborn hyperbilirubinemia and jaundice, conditions that cause a baby’s skin and tissues to turn yellow due to high levels of bilirubin.
6.1. Bilirubin Breakdown
Light therapy works by breaking down bilirubin, allowing the baby’s body to eliminate it properly.
6.2. Treatment Methods
- Placing the baby under halogen spotlights or fluorescent lamps with covered eyes
- Using biliblankets with fiber-optic cables that shine blue light onto the baby’s body
These methods are considered very safe, though some babies may experience short-term side effects like diarrhea, rashes, or dehydration.
7. What Are the Side Effects and Risks of Photo Therapy?
While generally safe, photo therapy can have side effects and risks that vary depending on the type of treatment.
