Why Cold Works Better Than Heat for Clogged Milk Ducts
I’ve been an International Lactation Consultant (IBCLC) for a very long time. Fifteen years to be exact. We were always trained that applying heat to clogged ducts was the surefire way to get relief and prevent mastitis. I’d advise mamas to take a hot shower, use warm compresses, and massage the area to get the milk going and clear the blockage. Recent research shows that’s the wrong recommendation. Cold is the new hot!
The Problem with Using Heat for Clogged Ducts
While heat on a clogged duct may provide temporary relief, it can actually make things worse. We now know that heat can worsen a situation by:
- Increasing inflammation: heat can cause blood vessels to expand and make matters worse. Applying cold will help reduce edema and calm down swelling
- Intensifying Engorgement: getting more engorged is the last thing you need. We need to decrease the inflammation so that the milk can drain
- Increasing Infection Risk: because heat not only keeps ducts inflamed and prevents proper milk flow, it can make things worse. Thel longer the milk stays clogged in the milk duct, the higher the risk for mastitis
On the Other Hand, Cold is Your Friend
If you have a clogged duct, here are the following recommendations:
- Apply cold compresses
- Breastfeed as usual
- GENTLE massage
- Take ibuprofen
- Get some rest and stay hydrated
If you still have a clogged duct after 24–48 hours and have flu-like symptoms like fever or chills, reach out to your OBGYN, midwife, or other healthcare provider.
