Quick answer
Use a hot therapy pack before nursing or pumping to help with milk flow and clogged ducts, and a cold therapy pack after feeding to reduce swelling from engorgement or mastitis.
When to use hot vs. cold therapy
Heat helps increase blood flow and encourages milk let-down, making it ideal before feeding or pumping if you have a plugged duct or slow flow. Cold therapy reduces inflammation and numbs sore tissue, which is best after nursing or when you are dealing with engorgement or mastitis symptoms.
Never apply heat for more than 15–20 minutes at a time, and always wrap the pack in a thin cloth to protect your skin. If you have mastitis with a fever, consult your healthcare provider before using heat.
Choosing the right therapy pack
Look for packs that can be used both hot and cold so you can adjust your treatment as symptoms change. The Lansinoh Hot & Cold Breast Therapy Packs are designed for this purpose — they can be microwaved or frozen without boiling water, and they conform to the breast for even coverage.
Avoid using standard gel packs or ice cubes directly on your breast, as they may not maintain a safe temperature or shape properly. Dedicated breast therapy packs stay flexible and are sized to target the right areas.
How to use hot and cold therapy packs for breastfeeding relief
- Step 1: Prepare the pack: For heat: microwave the pack for 15–30 seconds (check your pack’s instructions for exact time). For cold: place the pack in the freezer for at least 2 hours. Always wrap the pack in a clean, thin cloth before applying to your skin. Test the temperature on your wrist first to avoid burns or frostnip.
- Step 2: Apply heat before feeding or pumping: Place the warm pack on the affected area for 10–15 minutes before nursing or pumping. Gently massage the breast while the heat is applied to help loosen a clogged duct. Do not use heat for longer than 20 minutes — prolonged heat can increase inflammation.
- Step 3: Apply cold after feeding or pumping: After nursing or pumping, place the cold pack on the breast for 10–15 minutes to reduce swelling and numb pain. This is especially helpful for engorgement or mastitis discomfort. Limit cold application to 15–20 minutes per session, and allow at least 30 minutes between sessions.
- Step 4: Clean and store the pack: Wipe the pack with a damp cloth after each use and let it air dry before returning it to the freezer or a dry storage area. Do not submerge the pack in water or use harsh cleaners. Check the pack for cracks or leaks before each use — damaged packs should be replaced.
