A warm compress is an easy home remedy to increase blood flow to sore or infected body areas, which can reduce pain and speed up the healing process. Warm compresses can be moist and dry. You can use a warm compress for a wide range of conditions, like sore muscles, eye issues (especially to treat a stye), ear infections, cramps, and sinus congestion (although you should not use a warm compress within the first 48 hours of a muscle injury).
When to Use a Dry or Moist Warm Compress
Warm compresses bring more blood into an area. If you have an infection, like a stye or boil, the heat can also help draw pus from the skin, so that the boil (pus-filled bump) or stye (red bump on eyelod) can drain on its own. Never pop a boil or stye.
Warm compresses can be used for many conditions including:
- Boils
- Cysts
- Dry eyes
- Muscle strain or pain (after the first 48 hours)
- Period cramps
- Sinus infections
- Styes and eye infections
Moist Compresses
Research shows that moist compresses are more effective than dry compresses. The moisture helps retain heat, so that you don’t have to reheat the compress as often. It also helps the heat penetrate your muscles, which encourages more blood flow and healing. The downside to moist compresses is that they can be messy, and you may get wet. Moist compresses are used for:
- Boils and skin ailments
- Dry eyes, styes, and other eye issues
- Sore muscles
Dry Compresses
Dry compresses, like a microwavable heating pad, are a quick and easy solution for creating a warm compress. They don’t retain heat as long as moist compresses, but they also aren’t as messy. Dry compresses are most often used for sore muscles.
When to Skip Heat
Never apply heat within the first 48 hours of a muscle injury. It can contribute to inflammation and make the injury worse, not better.
How to Make a Moist Warm Compress
Making a moist compress can take a few minutes, but the compress will provide lasting warmth. If you use moist warm compresses often, you can purchase a reusable moist warm compress that is microwaved or dipped in hot water before use. Alternatively, you can make your own warm compress at home. Here’s how:
Bundle Method
Research has shown the bundle method is the most effective at delivering moist heat. Here’s how to do it:
- Gather two or three washcloths or hand towels. Alternatively, fold a larger towel into multiple layers.
- Soak the cloth in water, then wring excess water out.
- Wrap or fold the towels together, forming a multilayered bundle.
- Cover the bundle by placing it in a bowl covered with plastic wrap, or placing it in a plastic bag (unsealed).
- Heat the bundle in the microwave for two minutes.
- Test the temperature. The compress should be warm to the touch, but not hot or painful.
- Apply for 10 minutes at a time.
Basin Method
This method has fewer steps, but can lose heat more quickly. To try the basin method:
- Fill a bowl with hot (but not boiling or scalding) water.
- Soak a washcloth or small towel in the water.
- Squeeze out extra water (the water should be cool enough that this isn’t painful or dangerous).
- Fold the towel.
- Apply for 10 minutes.
If you need to minimize mess or wetness, you can put the wet towel in a plastic bag. Wrap another towel around the bag, and apply the compress to your skin.
Microwave Method
You can make a moist, warm compress by using a microwave. To do this:
- Soak two towels with water and wring out the excess.
- Place one towel in a ziplock bag, leaving the bag open
- Microwave on high for two minutes, and carefully remove the bag from the microwave and shut it tightly.
- Wrap the second wet towel around the microwaved bag and apply it to the appropriate area.
How to Make a Dry Warm Compress
A dry warm compress utilizes rice, beans, or grain. It is warmed in the microwave and slowly releases heat. The filling is usually encased within sealed fabric. Making a dry warm compress can be tricky, so many people who prefer dry heat opt to purchase a microwaveable heating pad. These compresses are filled with rice, beans, or grain that retain heat and can be used again and again.
However, it’s possible to make your own dry warm compress at home. Here’s how:
- Gather a sock that can be discarded.
- Fill half of the sock with rice.
- Tie the open end of the sock, so the rice cannot fall out. Leave enough room that the rice can spread out, and the sock has a floppy, not hard, feel.
- Heat the sock in the microwave for 30 seconds at a time, until you reach your desired temperature.
- Apply heat for 10 minutes.
Summary
A warm compress can feel nice, and it promotes healing by increasing blood flow to an area. Warm compresses can be dry or moist. Moist compresses are generally most effective, since the moisture helps the heat reach deeper into your tissues and encourages more blood flow. Dry compresses are often easy-to-use, and some people prefer a dry heat.
