At a glance
Swimming is one of the most frequently recommended exercises for people with anal fissures. It is low impact, does not put direct pressure on the perineal area, and provides both physical and mental health benefits. This guide covers the practical considerations.
Why swimming works well
- No impact — unlike running, there is no repeated jarring
- No pressure — unlike cycling or sitting exercises, there is no direct pressure on the area
- Buoyancy — takes weight off the body entirely
- Full body exercise — maintains fitness without targeting the problem area
- Mental health — many people describe swimming as particularly calming
Practical considerations
Pool chlorine
Chlorinated water comes into contact with the fissure area during swimming. Most people report no problems with this. A minority describe mild stinging, particularly during the first few swims or when the fissure is acute.
If chlorine causes discomfort:
- Shower immediately after swimming
- Apply a gentle, unscented barrier cream after showering
- Consider swimming in a salt water pool if available
Changing and showering
The communal changing room and shower environment adds a layer of complexity. People describe:
- Showering promptly after swimming to remove chlorine
- Patting the area dry gently rather than rubbing
- Changing into clean, dry underwear immediately
- Applying any prescribed topical treatment after cleaning
Timing around bowel movements
Swimming shortly after a bowel movement — when the sphincter is in spasm and the area is most sensitive — is generally less comfortable. If possible, time swimming sessions for periods when fissure symptoms are at their lowest.
What to wear
Standard swimwear is fine for most people. Some people prefer slightly looser trunks or shorts to reduce friction. Avoid sitting on wet swimwear for extended periods after swimming.
When to avoid swimming
- If you have had recent surgery and the wound is still open (check with your surgeon)
- During episodes of heavy bleeding
- If the chlorine consistently causes significant irritation despite the strategies above
- If you develop any signs of infection around the area
