1. What is heat therapy?
Heat therapy is the therapeutic application of heat to the body — to specific acupuncture points, areas of pain, or broader regions — to improve circulation, relieve pain and muscle tension, dispel cold and damp, and support the body’s natural healing processes. It is an integral component of traditional Chinese medicine (TCM) and has been used alongside acupuncture and moxibustion for thousands of years as a way of warming the body, moving qi and blood, and restoring balance in conditions dominated by cold and deficiency.
In my clinic I use heat therapy primarily through an acupuncture infrared heat lamp — specifically a TDP (Teding Diancibo Pu) mineral lamp — which emits far-infrared radiation at wavelengths closely aligned with those naturally emitted by the human body, allowing deep tissue penetration and absorption. This is typically positioned over the patient during the acupuncture session, providing continuous therapeutic heat to the treated area while the needles are retained. The warmth significantly enhances the relaxing, analgesic and circulatory effects of the treatment, and most patients find it one of the most pleasurable aspects of their session.
Heat therapy is particularly well-suited to conditions characterised by cold, stiffness and deficiency in TCM — such as back pain, neck pain, muscle pain, frozen shoulder, Kidney yang deficiency, and gynaecological conditions driven by cold in the uterus. It can be used as a standalone technique or, as is most common, as an add-on to acupuncture, electroacupuncture or cupping therapy within the same session. I offer heat therapy at my clinics in Wokingham, Berkshire.
2. History of heat therapy
The therapeutic use of heat is among the oldest medical practices known to humanity — present in virtually every traditional healing system across the world, from ancient Egypt and Greece to India, China and the indigenous healing traditions of the Americas. The application of warmth to areas of pain, stiffness and cold has been observed to bring relief for as long as people have experienced these complaints, and its therapeutic value is deeply embedded in both intuitive human experience and formal medical tradition.
In Chinese medicine, heat therapy has been practised alongside acupuncture and herbal medicine for at least 2,500 years. Moxibustion — the burning of dried mugwort (Artemisia vulgaris) at or near acupuncture points — is the classical TCM form of heat therapy and predates the development of metal needles. The Huangdi Neijing, the earliest known Chinese medical textbook (approximately 300 BCE), describes conditions in which heat and warmth are the appropriate therapeutic response and cold is contraindicated.
The TDP mineral lamp was developed in China in the 1980s by scientist Gou Wenbin at the Chongqing Institute of Ceramics, inspired by the observation that workers in a factory producing mineral clay had unusually low rates of musculoskeletal illness. Analysis of the clay revealed a high concentration of trace minerals. Wenbin developed a lamp with a mineral-coated plate containing 33 earth elements that, when heated, emit far-infrared radiation in the 2–25 micrometre wavelength range — the same spectrum naturally emitted by the human body. TDP lamps have since been adopted by acupuncturists and medical practitioners across China, Japan and increasingly in western countries.
3. Types of heat therapy used in acupuncture
Several forms of heat therapy are used within TCM and acupuncture practice. I use the following at my clinic:
Infrared TDP mineral lamp
The TDP (Teding Diancibo Pu, meaning “special electromagnetic spectrum”) lamp is the most effective and most commonly used form of heat therapy in contemporary TCM acupuncture practice. It emits far-infrared radiation in the 2–25 micrometre wavelength range from a mineral-coated plate containing 33 trace elements essential to the human body. This far-infrared energy penetrates up to 3–4 inches (7–10 cm) beneath the skin surface — far deeper than conventional heat sources — stimulating microcirculation, reducing inflammation, relaxing muscle tissue and supporting cellular repair. The TDP lamp is used positioned over the patient during an acupuncture session, typically over the back, abdomen, lower limbs or affected joint.
Moxibustion
Moxibustion is the burning of compressed mugwort herb at or near acupuncture points to apply direct or indirect heat stimulation. It is the classical TCM form of heat therapy, with a specific warming action on the meridians and organ systems that differs in character from infrared heat. Moxa is particularly used for conditions of Kidney yang deficiency, cold uterus, breech presentation and digestive cold. Please see the dedicated moxibustion page for full information.
Electric heated blanket
A gently heated electric blanket on the treatment couch provides whole-body comfort and warmth during acupuncture sessions — particularly important during colder months. In TCM, having acupuncture on a cold surface is considered counterproductive, as cold impedes the flow of qi and blood that the treatment is working to restore. Maintaining a warm, comfortable treatment environment significantly enhances the therapeutic effect of the session.
Heat packs and hot water bottles
For home self-treatment between clinic sessions, I recommend the use of a wheat bag, heat pack or hot water bottle applied to areas of pain, cold or tension. These provide surface heat and gentle comfort, particularly for conditions of lower back cold and pain, abdominal cold and menstrual cramping. They are most effective when used consistently and regularly rather than as a one-off intervention.
4. How does heat therapy work?
Heat therapy produces its therapeutic effects through a combination of physiological mechanisms that align closely with both western physiological science and TCM theory:
Improved circulation and microcirculation
Heat causes vasodilation — the widening of blood vessels — which increases blood flow to the heated area. Far-infrared radiation from the TDP lamp penetrates deeply into soft tissue, stimulating microcirculation: the movement of blood through the smallest capillaries and lymphatic vessels. Improved microcirculation accelerates the delivery of oxygen, nutrients and immune cells to damaged tissue, while simultaneously removing metabolic waste products, cellular debris and inflammatory mediators. In TCM terms, heat moves blood and qi, dispersing stagnation and nourishing depleted tissues.
Muscle relaxation and reduced spasm
Heat reduces muscle tone and relieves muscle spasm by reducing the sensitivity of the spindle fibres that control muscle contraction, and by directly relaxing the smooth muscle in blood vessel walls. This relaxation reduces pain from muscular tension, releases tightness in connective tissue and fascia, and improves the range of motion in affected joints. The deep penetration of infrared heat into muscle tissue produces a more sustained relaxation effect than surface heat sources.
Analgesia and pain relief
Heat activates thermal receptors in the skin and soft tissue that directly modulate pain signals in the spinal cord — a mechanism related to the gate control theory of pain. It also stimulates the release of endorphins and increases the production of nitric oxide, which promotes vasodilation and further amplifies the pain-relieving effect. Research has shown that infrared heat therapy produces significant reduction in chronic pain, including chronic low back pain, fibromyalgia, knee osteoarthritis and myofascial pain syndrome.
Anti-inflammatory effects
Far-infrared radiation has been shown to reduce levels of pro-inflammatory cytokines — the chemical messengers that drive chronic inflammation — and to promote the resolution of oedema and swelling. This anti-inflammatory mechanism is particularly important for chronic inflammatory conditions such as arthritis and tendinopathies, and complements the anti-inflammatory effects of acupuncture needling at the same session.
Immune activation
In TCM, a rise in body temperature is understood as the immune system working at optimal efficiency — the raised temperature allowing the body’s defensive qi (wei qi) to move more quickly and effectively against pathogens and dysfunction. This mirrors the western physiological understanding: mild therapeutic heat stimulates the production of heat shock proteins, activates immune cell function and improves the body’s innate resistance. People fall ill more frequently in cold conditions in part because reduced temperature slows the circulation of white blood cells and the speed of immune response. Heat therapy actively counters this process.
TCM mechanisms: moving qi and blood, warming yang
In TCM, heat is understood as a direct expression of yang energy — the warming, activating, moving force within the body. Qi (energy) flows more freely when the body is warm; blood, as a fluid, moves more readily in warmth than cold. The TDP lamp’s far-infrared radiation directly reinforces the warming and moving action of acupuncture treatment, particularly for Kidney yang deficiency — the constitutional cold pattern underlying many chronic conditions including infertility, low back pain, fatigue and poor circulation. Heat therapy activates specific acupuncture points and channels in a way that mirrors the warming action of moxibustion, but with the added benefit of continuous, precisely directed far-infrared penetration.
5. Health benefits of heat therapy
Heat therapy is used in conjunction with acupuncture at my clinic for a wide range of conditions. It is most beneficial for:
- Chronic and acute pain — back pain, neck pain, sciatica, muscle pain, frozen shoulder, tennis elbow, joint pain and arthritis
- Fibromyalgia — research has shown that infrared heat therapy produces significant reductions in fibromyalgia pain scores and Fibromyalgia Impact Questionnaire (FIQ) scores, improving both pain intensity and quality of life
- Muscle spasm and tension — the deep penetration of far-infrared heat is highly effective at releasing chronic muscle tightness and spasm, particularly in the back, neck and shoulders
- Cold conditions in TCM — conditions characterised by cold, stiffness, pallor and deficiency in TCM, including Kidney yang deficiency, cold uterus, abdominal cold and cold-type menstrual pain (dysmenorrhoea)
- Fertility — heat therapy over the lower abdomen and lower back during acupuncture supports the treatment of cold uterus patterns and Kidney yang deficiency that impair fertility, complementing the hormonal and circulatory effects of the acupuncture itself
- Post-injury recovery — heat applied after the acute inflammatory phase of an injury (typically 48–72 hours after injury) promotes tissue healing by improving circulation to the damaged area and accelerating cellular repair
- Immune support — regular heat therapy supports the body’s immune function, particularly in people who are constitutionally cold, frequently ill or run down
- General relaxation and stress reduction — the warmth of the TDP lamp during acupuncture significantly deepens the relaxation response of the treatment, enhancing the effects on the nervous system and amplifying the reduction in cortisol and sympathetic activation
6. Is heat therapy safe?
Yes — heat therapy using an infrared TDP lamp is safe when applied by a qualified practitioner at the correct distance and duration. The lamp is positioned at 30–50 cm from the body surface and the intensity of warmth is adjusted to ensure the patient experiences a comfortable, therapeutic warmth — never hot enough to cause discomfort. The TDP lamp automatically regulates output, and I monitor the patient’s comfort throughout the session.
The following situations require caution or avoidance of heat therapy:
- Active acute injury or inflammation (the first 48–72 hours following trauma) — heat is not applied directly to acutely inflamed tissue, as it can increase swelling in the immediate post-injury phase. Heat becomes appropriate once the acute inflammatory phase has resolved.
- Directly over open wounds, broken skin or areas of active infection
- Areas with significantly impaired sensation — patients who cannot reliably report heat sensation (e.g. due to peripheral neuropathy) require extra care
- Areas of active malignancy — heat therapy should not be applied directly over known or suspected tumours
7. Side effects of heat therapy
Heat therapy using the TDP lamp has minimal side effects when properly applied. The most common minor response is temporary redness of the skin in the treated area (erythema), which fades within minutes to an hour of treatment. This is a normal physiological response to heat and increased blood flow and is not a cause for concern.
Prolonged direct heat from contact heat sources (such as heat wraps left in place for extended periods) can cause a skin condition called erythema ab igne — a mottled, reddish-brown discolouration from repeated heat exposure. This is the reason I do not recommend using electric heat wraps directly on the skin for extended periods. The TDP lamp, being a non-contact radiant heat source applied at a distance, does not carry this risk when used correctly.
Excessive heat applied for too long to a single area can, in rare cases, cause a superficial burn — which is why I always monitor the lamp position and patient comfort throughout the session. Patients should always tell me if the heat becomes too intense at any point.
8. Heat therapy in pregnancy
Heat therapy can be used safely during pregnancy with appropriate modifications. It should not be applied directly over the abdomen or lower uterine area during pregnancy, as excessive heat in this region can cause the baby to become restless and is not appropriate. Similarly, moxibustion on the abdomen is avoided during pregnancy.
However, heat therapy can be comfortably and beneficially applied to other areas of the body during pregnancy — including the upper and mid-back, shoulders, legs and feet — to provide relief from pregnancy-related pain, muscle tension and the general cold and fatigue that many women experience, particularly in the later stages of pregnancy. Heat over the lower back (below the level of the uterus) is generally comfortable and beneficial for pregnancy-related back pain.
At home, a hot water bottle applied to the mid or upper back, or a warm bath, is perfectly safe and beneficial during pregnancy. Excessively hot baths or saunas should be avoided as they can raise core body temperature to levels that are inappropriate during pregnancy.
9. Why Chinese medicine avoids cold therapy
One of the most practically distinctive aspects of TCM is its consistent recommendation of heat over cold — even for conditions that western physiotherapy would typically treat with ice or cold packs. This reflects a fundamentally different understanding of how the body functions and heals.
In Chinese medicine, cold is understood as a pathological force that causes contraction, stagnation and obstruction. When cold invades the body — whether from the external environment, cold food and drink, or the application of cold therapy — it causes the contraction of channels, blood vessels and muscles, which slows circulation and impairs the flow of qi and blood. Far from resolving inflammation, cold in TCM is considered to drive it deeper and potentially create more persistent, chronic problems. This is why TCM consistently recommends warm baths, hot water bottles and heat therapy rather than ice packs for acute joint pain and musculoskeletal injuries — even when swelling is present.
This does not mean that western ice therapy is always harmful — in a very acute injury with significant bruising and haemorrhage, brief cold application to reduce immediate swelling has a rationale. But the routine use of cold packs as the default treatment for all musculoskeletal pain and inflammation — which is standard in physiotherapy and sports medicine — is inconsistent with the TCM understanding of how the body heals, and in my clinical experience, patients who use heat rather than cold for their musculoskeletal pain consistently recover faster and experience less residual stiffness.
For ongoing joint pain, back pain and muscle pain, I recommend hot baths, warm showers, wheat bags, hot water bottles and the use of heat therapy in clinic as part of an ongoing management strategy. Many patients are surprised by how much relief a consistently warm treatment approach provides compared to the cold packs they have been using.
10. Commonly asked questions about heat therapy
What is the TDP lamp used in acupuncture?
The TDP lamp (Teding Diancibo Pu — “special electromagnetic spectrum”) is a far-infrared mineral lamp developed in China in the 1980s. It differs from a standard infrared heat lamp in containing a mineral-coated plate with 33 trace elements that, when heated, emit far-infrared radiation in the 2–25 micrometre wavelength range — the same spectrum the human body naturally emits. This allows the energy to be readily absorbed by the body’s tissues, penetrating up to 3–4 inches beneath the skin surface to stimulate deep microcirculation, reduce inflammation and relax muscles. It is widely used by acupuncturists in China and increasingly in western acupuncture clinics.
Is heat better than ice for pain and injuries?
In TCM, heat is almost always preferred over cold for both acute and chronic musculoskeletal pain. Cold causes vascular contraction and impairs the circulation needed for tissue repair; heat promotes vasodilation and accelerates healing by improving blood flow to damaged tissue. The one exception is the immediate acute phase of a significant injury with active bleeding or bruising, where brief cold application can limit initial swelling. Once that acute phase has passed (typically after 48–72 hours), heat is consistently more beneficial than cold for recovery. For chronic pain conditions, heat is always preferable.
Can I use heat therapy at home between sessions?
Yes — I actively encourage patients to use heat at home between clinic appointments. A wheat bag, hot water bottle or warm bath applied to areas of pain, tension or cold is a useful supplement to clinic treatment. For gynaecological conditions with cold uterus patterns, regular warmth over the lower abdomen and lower back — applied for 20–30 minutes before bed — is a simple and effective self-care measure. Personal TDP lamps are available for home use if you wish to replicate the clinic treatment at home.
Does heat therapy cost extra?
No — heat therapy using the TDP lamp is included as part of the standard acupuncture session fee with no additional charge. Full pricing information is on the treatment prices page.
