Cold Therapy, Cryotherapy, and Hidradenitis Suppurativa
Cold therapy involves exposing the body to low temperatures in order to reduce inflammation and pain. This page explores what cold therapy is, why HS patients are interested in it, what the research says, and how to use it safely.
Proper cold therapy application with a protective cloth barrier between the cold pack and skin

What Cold Therapy Is
Cold therapy involves exposing the body to low temperatures in order to reduce inflammation and pain. It is one of the oldest and most widely used physical therapy approaches, with applications ranging from simple home remedies to advanced clinical cryotherapy systems.
Cold exposure has been used in sports medicine and rehabilitation for decades, primarily to manage acute injuries, reduce post-exercise inflammation, and accelerate recovery. Its application to chronic inflammatory skin conditions like HS is a more recent area of patient interest.
Common Forms of Cold Therapy
Ice packs
Reusable gel packs or crushed ice in a bag, applied with a cloth barrier
Localized cold therapy devices
Clinical devices that circulate cold water or compressed gas to a targeted area
Whole-body cryotherapy chambers
Enclosed chambers reaching -110 to -140 degrees Celsius for 2-4 minutes
Cold therapy reduces inflammation through vasoconstriction, reduced blood flow, and decreased inflammatory cytokine signaling at the cellular level.
Why HS Patients Are Interested
Inflammation plays a central role in HS. Because cold therapy is widely known to reduce inflammation in other conditions, many HS patients naturally explore whether it can help manage their symptoms.
Reducing Swelling
Cold temperatures cause vasoconstriction - narrowing of blood vessels - which can reduce fluid accumulation and visible swelling around HS lesions.
Numbing Pain
Cold exposure temporarily reduces nerve conduction velocity, which can provide short-term pain relief during and after HS flare-ups.
Decreasing Inflammatory Signaling
Cold temperatures can slow down the release of pro-inflammatory cytokines and reduce the metabolic activity of immune cells in affected tissue.
Slowing Nerve Activity
Cold therapy slows nerve activity in inflamed tissue, which can interrupt the pain-inflammation cycle that makes HS flares so difficult to manage.
Some patients report that cold compresses provide temporary relief during HS flare-ups, particularly for managing the intense pain and swelling that can accompany active lesions. This patient-reported experience is one reason cold therapy continues to be explored as a complementary approach, even in the absence of large clinical trials specifically for HS.
What Research Says
Limited HS-specific research
Scientific research specifically examining cryotherapy for HS is limited. There are no large randomized controlled trials (RCTs) confirming cold therapy as an effective treatment for HS. Most available evidence comes from its use in other inflammatory conditions.
Cold therapy is widely used for other inflammatory conditions and may help manage symptoms such as:
- Pain management during and after flare-ups
- Swelling and fluid accumulation around lesions
- Localized inflammation in affected skin areas
Research Gaps
- No large-scale RCTs specifically for HS
- Optimal temperature, duration, and frequency for HS are not established
- Long-term effects on HS disease course are unknown
- Most dermatology guidelines do not list cold therapy as a standard HS treatment
More clinical research is needed to determine the effectiveness of cold therapy specifically for HS. Until that evidence exists, it should be considered a supportive symptom-management tool rather than a disease-modifying treatment.
Whole-body cryotherapy chambers expose the body to temperatures between -110 and -140 degrees Celsius for 2-4 minutes. Clinical supervision is required.
Practical Uses
Many patients experiment with simple cold therapy approaches at home. These methods are generally low risk when used properly, though they should always be discussed with a healthcare provider.
Cold Compresses During Flare-Ups
A cold compress or cooling gel pack wrapped in a clean cloth can be applied to inflamed HS areas for 15-20 minutes at a time to reduce swelling and numb pain during active flares.
Cooling Gel Packs
Reusable gel packs that can be stored in a refrigerator (not freezer) provide a gentler, more consistent cold temperature than ice packs, reducing the risk of skin irritation.
Brief Cold Exposure
Some patients use brief cold showers or targeted cold water exposure to affected areas as part of their daily hygiene routine to help manage localized inflammation.
These methods are generally low risk when used properly. However, patients with open or draining HS lesions should consult their dermatologist before applying cold therapy directly to affected areas, as cold exposure over open wounds carries additional risks.
Safety Considerations
Cold therapy should be used cautiously. While generally safe when applied correctly, improper use can cause additional harm - particularly for HS patients whose skin is already compromised.
Safe Use Guidelines
- Always use a protective cloth or towel between cold pack and skin
- Limit each cold therapy session to 15-20 minutes maximum
- Allow skin to return to normal temperature before reapplying
- Use refrigerated gel packs rather than frozen ice when possible
- Discuss with your dermatologist before applying to open lesions
Potential Risks
- Frostbite from excessive cold exposure or direct ice contact
- Skin irritation, especially over already compromised HS skin
- Nerve damage if cold is applied too long or too intensely
- Worsening of open wounds if applied without proper precautions
- Raynaud's phenomenon flare in patients with vascular sensitivity
Key Rule: Always limit exposure time and avoid placing ice directly on bare skin. Never apply cold therapy to open, draining, or actively infected HS lesions without explicit guidance from your healthcare provider.
Frequently Asked Questions
Can cold therapy cure HS?
No. Cold therapy cannot cure HS. It may provide temporary symptom relief - particularly for pain and swelling during flare-ups - but it does not address the underlying immune dysfunction driving HS. It should be used alongside, not instead of, evidence-based medical treatments.
Is it safe to apply ice directly to an HS lesion?
No. Ice should never be applied directly to bare skin, especially over open or draining HS lesions. Always use a protective barrier such as a cloth or towel between the cold pack and your skin, and limit application to 15-20 minutes at a time to avoid frostbite or skin irritation.
What is the difference between cold therapy and cryotherapy for HS?
Cold therapy is a broad term covering any use of low temperatures for therapeutic benefit, including ice packs, cooling gel packs, and cold compresses. Cryotherapy typically refers to more intensive cold exposure such as whole-body cryotherapy chambers (reaching -110 to -140 degrees Celsius) or localized cryotherapy devices used in clinical settings.
How long should I apply a cold compress during an HS flare?
Generally, cold therapy sessions should be limited to 15-20 minutes at a time with a protective cloth barrier. Allow the skin to return to normal temperature before reapplying. Avoid using cold therapy on open wounds or actively draining lesions without guidance from your healthcare provider.
Is whole-body cryotherapy recommended for HS?
Whole-body cryotherapy is not a guideline-recommended treatment for HS. While it is used for other inflammatory conditions, there is currently no large-scale clinical evidence confirming its effectiveness specifically for HS. Some patients explore it as a complementary approach, but it should be discussed with a dermatologist first.
