Warm Compress or Soak


A warm compress or soak helps improve blood flow to tissues and relieve pain and swelling. This will help you heal from an injury or illness.


Call your doctor if:

  • Your symptoms do not improve or you have new symptoms.
  • You see blisters on the area where you applied the compress or soak.
  • You have questions or concerns about your condition or care.

How to prepare and use a moist warm compress:

Your healthcare provider will tell you how often to apply a warm compress:

  • Wash your hands.
  • Use a washcloth, small towel, or gauze as your compress.
  • You can place the compress under running water or place it in a bowl with warm water. Check the temperature of the water with a thermometer. The water should not be warmer than 100°F (37.8°C) for babies and children, 120°F (49°C) for adults, and 100°F (37.8°C) for older adults. Adults should use water that is 100°F (37.8°C) if they will apply the compress to an eye.
  • If directed, add 1 tablespoon of salt to the water. Squeeze extra water out of the compress.
  • Place the compress directly on the area. If directed, gently massage the area with the compress. Check your skin in 2 minutes for blisters or bright red skin. Your skin should look pink to light red.
  • You may need to rewarm the compress every 5 minutes.
  • Remove the compress in 15 to 30 minutes, or when the compress starts to feel cold. Gently pat your skin dry with a clean towel.
  • Wash your hands.
  • Reapply the compress as many times as directed each day. Use a clean compress every time.

How to use a dry warm compress:

A dry compress may be a hot water bottle or a heating pad. You can also buy a prepared hot pack. Follow the package directions for how to use these devices. Cover a bottle or hot pack with a towel before you apply it to your skin. Do not leave a dry compress on your skin for more than 20 minutes or as directed. Do not fall asleep with a dry compress on your skin. A dry compress may burn your skin if it is left on for too long.

How to prepare and use a warm soak:

  • Fill a clean container or tub with warm water and soap. The container should be deep enough to cover the area completely.
  • Check the temperature of the water with a thermometer. The water should not be warmer than 100°F (37.8°C) for children and babies, and 110°F (43°C) for adults.
  • If directed, add 1 tablespoon of salt to the water.
  • Remove any bandages.
  • Soak the area for 30 minutes or as long as directed. Gently pat your skin dry when you are done soaking.
  • Replace bandages as directed.
  • Clean the container or tub when finished.
  • Wash your hands.
