Back pain is the most common complaint in the Netherlands: according to the RIVM, more than 1 in 3 adults regularly suffer from back or neck pain, and lower back pain is the largest cause of disability worldwide. Infrared therapy relieves back pain by deeply heating muscle and connective tissue around the spine, increasing local blood flow and inhibiting low-grade inflammation in the surrounding tissue. Clinical studies consistently show that heat therapy for non-specific low back pain is more effective than placebo and comparable to short-term NSAID use, without the side effects.
This article explains which types of back pain respond to light therapy, how to set up the protocol at home, which products are most suitable and what you can realistically expect.
Three types of back pain: which responds to light therapy?
Not all back pain is the same. Before you start, it is important to know which category applies to you.
1. Non-specific low back pain
This is the most common form: pain in the low back without an identifiable structural cause such as a hernia or vertebral fracture. Often caused by muscle tension, overload, poor posture or sitting for long periods of time. This is exactly the complaint for which infrared therapy has the strongest evidence. A Cochrane Review (French et al., 2006, confirmed in updates 2021) concluded that superficial heat therapy provides statistically significant pain relief in acute non-specific low back pain, comparable to ibuprofen in the short term.
2. Muscle tension and myofascial pain syndrome
Trigger points and tense muscle bands in the back, gluteal muscles and hip flexors are a direct cause of chronic back pain in office workers and people with unilateral strain. Infrared heat relaxes muscle fibers, improves blood flow to the affected fascia and reduces local nociceptive activity. Also read our blog about it infrared therapy for muscle pain for the complete mechanism.
3. Back pain due to osteoarthritis or degeneration (facetarthrosis)
Infrared therapy works as additional pain relief for degenerative back problems, where the facet joints or intervertebral discs are worn out. It does not restore disc height or cartilage, but it relieves the chronic low-grade inflammation that perpetuates the pain. See also our about page chronic pain and light therapy. In case of hernia or radiculopathy (radiating pain), always consult a doctor first.
The mechanism: why heat and red light work on the back
The back consists of several layers: skin, subcutaneous fatty tissue, fascia, muscles (erector spinae, multifidus), ligaments and the spine itself. Infrared-A radiation penetrates up to 6 millimeters deep and reaches the superficial muscle layers and fascia directly. This produces four demonstrable effects:
Vasodilation: dilate the blood vessels in the treated area. Oxygen and nutrients flow faster to tense or irritated tissue. Lactic acid and inflammatory substances are removed more quickly. This is why back pain feels less 'tight' after an infrared session.
Break muscle spasm: heat lowers the threshold value of the muscle spindle, the mechanism that keeps muscles in a cramped state. This is the immediate relaxing effect that most people feel first, sometimes within five minutes.
Inflammatory modulation via photobiomodulation: Near infrared in the 810-850 nm range activates cytochrome c oxidase in the mitochondria of muscle cells, which inhibits the production of pro-inflammatory cytokines such as IL-6 and TNF-alpha. This is a deeper, cellular effect on top of the pure heat effect. More about this mechanism in our blog photobiomodulation explained.
Endorphin release: heat stimulates the production of beta-endorphins, the body's own painkillers. The pain-relieving effect lasts after the session is over, sometimes for several hours.
Protocol: how do you use an infrared lamp for back pain?
Basic protocol for lower back
| Parameter | Recommendation |
|---|---|
| Distance | 25-40 cm from the skin |
| Session duration | 15-20 minutes |
| Frequency | Daily for acute pain, 4-5x per week for chronic complaints |
| Timing | In the morning before getting up or in the evening before going to sleep |
| Position | Lying on the stomach, lamp above the lower back; or standing with lamp on tripod |
| Skin | Clean and dry, no creams just before the session |
The three zones for back pain
Back pain rarely has one exact spot. Treat in order:
Zone 1: low back (L3-L5, sacrum) — this is the most common pain area. Direct the lamp at the spine and the paravertebral muscles to the left and right of it.
Zone 2: glutes and piriformis — if there is radiating pain or stiffness in the buttocks, also aim the lamp at this zone. The piriformis is an overlooked cause of lower back pain in many people.
Zone 3: hip flexors (front of hip) — in people who sit a lot, the hip flexors are shortened and pull on the lumbar spine. Treatment of the front provides indirect relief in the back.
Which product is suitable for back pain?
Double Infrared Lamp — the most popular choice for back pain
The Double Infrared Lamp has two light heads that provide a wide beam angle. This is ideal for the lower back because it treats both the spine and the surrounding muscles at the same time. The two heads together provide an irradiation area of approximately 30x20 cm, exactly the size of the lumbar region.
This is the device for: acute attacks, chronic tension, daily routine.
TDP Lamp — for deep, mineral-rich heat for persistent back problems
The TDP Lamp combines infrared heat with a ceramic mineral plate. Has been used for decades in physiotherapy practices for persistent back and joint complaints. The heat feels deeper and lasts longer than with a standard infrared lamp.
This is the device for: chronic back pain, facet arthrosis, persistent muscle tension that does not respond to regular heat therapy.
Elite Series 306 — for those who also want to combine red light therapy
The Elite Series 306 supplies red light (660 nm) in addition to infrared (850 nm). This adds the photobiomodulation layer that has extra value in chronic inflammation. This is the most versatile investment for people with back pain and other complaints (skin, recovery).

When will you notice results?
In case of acute muscle tension (overload, incorrect movement): relief during or immediately after the first session. For chronic lower back pain: noticeable improvement in daily stiffness and pain level after 5-10 sessions, consistent effect after 2-4 weeks of daily application.
Back pain that returns after each treatment without structural improvement requires a broader approach. Infrared therapy is most effective as part of a routine that also includes exercise, ergonomics and possibly physiotherapy.
Infrared therapy as part of a broader back routine
Ergonomics: Most lower back pain in office workers is caused by posture or strain. Infrared treats the pain; a good office chair and exercise treat the cause.
Movement: Light exercise after an infrared session (walking, light stretching) strengthens the vasodilation effect and further stimulates blood flow.
Sleeping position: lying on the back with a pillow under the knees or lying on the side with a pillow between the knees reduces the load on the lumbar spine during sleep.
Physiotherapy: Physiotherapy is the appropriate treatment for chronic or structural back problems. Infrared therapy supports the recovery process and relieves pain between sessions.

Frequently asked questions about light therapy for back pain
Does an infrared lamp help with a hernia? For a hernia with radiating pain (radiculopathy), infrared therapy is not the primary treatment and heat can worsen the inflammation in the acute phase. Always consult a neurologist or orthopedic surgeon first. In case of a healed hernia or residual muscle tension after treatment, infrared can be useful as additional pain relief.
How long should I use infrared therapy for back pain? For acute non-specific back pain: daily until the pain disappears, usually 3-10 days. For chronic complaints: as structural maintenance 3-5 times a week, comparable to an exercise routine. Don't stop once the pain subsides; consistency prevents recurrence.
Can I use the infrared lamp if I have back pain and am pregnant? Heat therapy on the abdomen or lower back is not recommended during pregnancy. Consult your obstetrician or gynecologist before use.
Is the Double Infrared Lamp also suitable for the upper back and neck? Yes. The two heads provide sufficient radiation width for the upper back and trapezius. Direct the lamp at shoulder blades and neck to treat tension in that area. See also our page neck and shoulders.
Can I combine infrared with my back medication or muscle relaxant? Infrared therapy does not interfere with NSAIDs, paracetamol or muscle relaxants. It is a complementary, non-pharmacological intervention. Consult your doctor if you have any doubts about specific combinations.
