Heat or Ice for Lower Back Pain? What the Evidence Says
French's 2006 Cochrane review included nine trials (1,117 people). It reports moderate evidence, in a small number of trials, that heat-wrap therapy provides a small short-term reduction in pain and disability in a population with a mix of acute and sub-acute low back pain. Two trials of 258 people with a mix of acute and sub-acute low back pain found heat-wrap therapy reduced pain after five days versus oral placebo. The review finds not enough evidence on cold for low back pain of any duration, and no conclusions can be drawn from three poor-quality studies. For acute or subacute low back pain, the 2017 American College of Physicians guideline includes superficial heat, with moderate-quality evidence, within a strong recommendation. The guideline states that most patients with acute or subacute low back pain improve over time regardless of treatment.

I had low back pain for about ten years and have no medical credentials. Every research figure below comes from a source listed at the end of the page.
What the research and guidelines found
| Source | Finding | Certainty |
|---|---|---|
| French 2006 | Heat wrap therapy reduced pain after five days versus oral placebo in two trials of 258 people with a mix of acute and sub-acute low back pain. | There is moderate evidence that heat wrap therapy reduces pain and disability for back pain that lasts less than three months. The relief has only been shown for a short time, and the effect is relatively small. |
| French 2006, cold | For low back pain of any duration, cold evidence is not enough, from three poor-quality studies, and no conclusions can be drawn. | For low back pain, there is conflicting evidence on differences between heat and cold, and the evidence on cold is even more limited. |
| ACP 2017 | For acute or subacute low back pain, ACP includes superficial heat (moderate-quality evidence) among nonpharmacologic options in a strong recommendation. | Most patients with acute or subacute low back pain improve over time regardless of treatment. |
| ACP 2017, chronic | For patients with chronic low back pain, exercise is an initial nonpharmacologic option, and superficial heat is not listed. | For patients with chronic low back pain, Qaseem 2017 grades the recommendation strong, with moderate-quality evidence for exercise, multidisciplinary rehabilitation, acupuncture, and mindfulness-based stress reduction, followed by other options. |
| WHO, 7 December 2023 | The 7 December 2023 news release does not discuss heat or ice for adults with chronic primary low back pain (more than 3 months, not due to an underlying disease or other condition). | For adults with chronic primary low back pain, the 7 December 2023 WHO news release gives no per-intervention certainty grades. |
Adding exercise to heat-wrap therapy further reduces pain and improves function for a mix of acute and sub-acute low back pain, French's 2006 Cochrane review reports, with moderate evidence in a small number of trials. The review finds not enough evidence on heat for back pain lasting longer than three months.
In NICE NG59, acute means less than 3 months and chronic means 3 months or longer. For people over 16 with low back pain with or without sciatica, the recommendations do not mention heat or ice. For people over 16 with a specific episode or flare-up of low back pain with or without sciatica, recommendation 1.2.2 says to consider a group exercise programme within the NHS, taking people's specific needs, preferences and capabilities into account.
What to do in practice
- For people with low back pain with or without sciatica, NICE 1.2.1 (2016) says provide advice and information tailored to needs and capabilities at all steps of the treatment pathway, including the nature of low back pain and sciatica and encouragement to continue normal activities.
- For patients assessed after a minor back injury, the East Kent Hospitals leaflet (last reviewed July 2026) says heat or ice may provide temporary relief, and to use whichever feels most comfortable.
- For patients assessed after a minor back injury, wrap an ice pack, a bag of frozen vegetables, or a cold flannel in a towel on the painful area for up to 10 to 15 minutes, and never apply ice directly to your skin.
- For patients assessed after a minor back injury, the East Kent Hospitals leaflet says heat should not be hot enough to burn your skin, and not to fall asleep while using a heat or ice pack.
- For patients assessed after a minor back injury, East Kent's leaflet says do not use heat or ice with a skin abnormality such as poor circulation or thin shiny flaky, dry skin, with numb skin, with Sickle Cell Anaemia, or if it makes symptoms worse.
Where the program in the app fits
Low Back Pain Coach runs guided sessions on a required 45-degree back-extension bench. Floor Foundations last only until you have a bench, and the program is not written for a vertical 90-degree Roman chair. Recent workouts and pain logs help set the next session. The next-morning rule is a pacing rule, not a diagnostic test. The first guided session is free, as are the pain log, calendar, 30-day graph, CSV export, lessons, and flare help. Later guided sessions need a plan. The program is for chronic pain in people cleared to exercise. After a recent acute injury, fall, car accident, or surgery, finish the recovery plan your doctor set first. The exact bench progression has not been tested in a trial.
When to get care
Go to emergency care now for any of these:
- New numbness, tingling or change in feeling in the saddle area: around the groin, inner thighs, genitals or anus, or when you wipe
- New trouble getting or keeping an erection, not being able to orgasm, or a change in feeling during sex
- New bladder or bowel changes: trouble starting or stopping pee, a weak stream, not feeling when you need to go, or leaking pee or poo
- New pain, tingling, numbness or weakness in both legs
- Leg or foot weakness that is getting worse (tripping, a foot that slaps down)
- Back pain that started after a recent serious accident, like a car crash or a bad fall
See a clinician today (urgent care if no appointment today) for any of these:
- Other new weakness or numbness in one leg or foot
- Fever or chills alongside the back pain
- New pain after a recent smaller fall or knock
- Unexplained weight loss, or a history of cancer
- Pain that is rapidly getting worse
- Pain that is constant at rest and worse at night, not tied to movement
Common questions
Should I use heat or ice for lower back pain?
For acute or subacute low back pain, the 2017 American College of Physicians guideline says most patients improve over time regardless of treatment, and includes superficial heat (moderate-quality evidence) among the nonpharmacologic options in a strong recommendation. French's 2006 Cochrane review draws no conclusions on cold for low back pain of any duration.
How large was the heat-wrap difference in the trials?
French's 2006 Cochrane review reports moderate evidence, in a small number of trials, that heat-wrap therapy provides a small short-term reduction in pain and disability in a population with a mix of acute and sub-acute low back pain. Two trials of 258 people with a mix of acute and sub-acute low back pain found heat-wrap therapy reduced pain after five days versus oral placebo.
Does ice help lower back pain?
French's 2006 Cochrane review located three poor-quality studies on cold for low back pain of any duration and states that no conclusions can be drawn. Evidence on differences between heat and cold for low back pain is conflicting, and the evidence on cold is even more limited.
Does NICE recommend heat or ice for low back pain?
For people over 16 with low back pain with or without sciatica, NICE NG59 (published 30 November 2016, last updated 29 July 2026) does not mention heat or ice. Recommendation 1.2.1 (2016) says to provide advice and information tailored to their needs and capabilities at all steps of the treatment pathway, including the nature of low back pain and sciatica and encouragement to continue with normal activities.

The app
Low Back Pain Coach runs a guided strength program on a 45-degree back-extension bench: floor work until you have a bench, then four stages from short holds to weighted reps. You log your pain the next morning, and that log sets the next session. A voice counts the holds, reps and rest.
Your first guided session is free. Then $59.99 a year or $9.99 a month, renewing until you cancel, with a 7-day free trial for eligible new subscribers. US prices. iPhone and Android. The 45-degree bench is required. What the app does.

The printable program card has the four stages, the next-morning rule, and the stop signs on one sheet.
