Swimming with HS: pools, open wounds and what to do before you get in

Swimming can be a lower-friction way to stay active with HS. An open or draining wound changes the decision.

Choose where you plan to swim and what your skin is like today. You'll get a general steer — not a personal medical clearance.

This guide does not assume that chlorine or salt water treats HS. Evidence for that is limited, and we say so directly.

This page keeps HS-specific evidence, general recreational-water safety guidance and areas where evidence is limited clearly separate.

Can I swim with HS?

General recreational-water guidance

An open wound changes the risk

General recreational-water guidance recommends staying out of the water with an open wound where possible. If you do swim, completely cover the wound with a waterproof bandage.

Preventing Swimming-related Illnesses

Evidence limited

Chlorine is not an HS treatment

Some people report that chlorinated water feels better; others find it irritating. There isn't enough evidence to present pool chlorine as a treatment for HS.

Can the wound be completely covered with a waterproof dressing? Completely covered means the dressing forms a waterproof seal around the wound, not simply that the dressing itself is labelled water-resistant.

What to consider

Answer the questions above to see guidance.

Pool, sea, lake or hot tub — what's different?

Chlorinated pool

What we know: Properly maintained chlorine and pH levels reduce many waterborne germs. That does not make chlorinated water sterile, and chlorine can irritate skin.

In practice: Closed skin: generally reasonable if comfortable. Open wound: staying out is the lower-risk option; otherwise use complete waterproof coverage.

Sea / ocean

What we know: Natural water can contain microorganisms, and contaminated water entering an open wound may cause infection.

In practice: Check current official water-quality advisories. Open wounds warrant additional caution.

Lake / river

What we know: The same principle applies to lakes and rivers as to the sea — with the added wrinkle that not every inland waterway, especially smaller streams, is routinely monitored for water quality.

In practice: Check whether official quality data exists for your specific spot before entering with an open wound.

Hot tub / spa

What we know: A hot tub is not equivalent to a swimming pool. Warm water and a shared spa environment introduce different heat and hygiene considerations than a pool built for swimming.

In practice: If heat aggravates your HS, or you have an open wound, skipping the hot tub is the more conservative option.

Before you swim

A fixed, editorially reviewed checklist — independent of whatever you selected above.

  • Look at the area: closed, open, draining, or recently operated on?
  • If there's an open wound: decide whether swimming today is worth the additional exposure.
  • If swimming with a covered wound: make sure the dressing forms a complete waterproof seal.
  • Bring replacement wound-care supplies if you normally change dressings regularly.
  • For natural water: check current water-quality notices before swimming.
  • Choose swimwear that doesn't create painful rubbing at your usual HS sites.

After swimming

Get out of wet swimwear promptly, rinse or shower, gently dry the skin, and return to your usual wound-care routine.

If a dressing became wet, loosened or contaminated, replace it following your own wound-care instructions.

If swimming repeatedly leaves your skin noticeably more irritated, that's useful information — you don't need to keep using an activity simply because it's often described as "HS-friendly".

Frequently asked questions

Does chlorine help hidradenitis suppurativa?

There isn't enough evidence to recommend chlorinated pool water as an HS treatment. Individual experiences differ: some people report no problem or subjective improvement, while others find chlorine drying or irritating.

Can I swim with an open HS wound?

General recreational-water guidance recommends staying out of the water with an open wound where possible. If you do swim, completely cover the wound with a waterproof bandage. Natural water can additionally contain microorganisms that may enter open wounds.

Is the sea better than a chlorinated pool for HS?

There's no good evidence that one treats HS better than the other. Natural water and managed pools carry different risks, particularly when skin is open.

Can I swim after HS surgery?

Follow the instructions from the team managing your surgical wound. The right timing depends on the operation and wound healing — a generic timeline from this website should not replace those instructions.

Should I cover HS lesions in the pool?

Closed lesions don't automatically need a dressing just because you're swimming. For an open wound, general safety guidance recommends completely covering it with a waterproof bandage while swimming.
