How a cold therapy machine works
Main components
A cold therapy machine uses several key parts to deliver effective pain relief and swelling reduction. You will find these main components in most machines:

|
Component |
Function |
|---|---|
|
Central cooling and water cycling chamber |
Maintains the cold temperature and circulates water for effective cooling. |
|
Tubing |
Transports the cooled water from the chamber to the treatment area. |
|
Compression wrap |
Applies pressure and holds the cooling pads in place on the body part being treated. |
You will also see these features in many devices:
- Reservoir for ice and water: Holds the ice and water mixture for cooling.
- Pump: Circulates the cooled water through the system.
- Specialized pads: Fit the treatment area, making sure you get the best cold therapy.
These parts work together to give you steady and targeted relief.
Cooling and compression process
When you use a cold therapy machine, you fill the reservoir with ice and water. The pump moves the cold water through the tubing and into the therapy pad. This pad wraps around your knee, shoulder, or other body part. The cold water flows through the pad, keeping the area at a steady, low temperature.
The machine’s insulated system helps keep the water cold for a long time. Many machines, like the Novarhome Cold Therapy Machine, let you adjust the timer and flow rate. You can set your session for as little as 10 minutes or as long as 60 minutes. Most people use cold therapy for about 15 minutes at a time. This length of time helps lower swelling and pain without harming your skin.
Compression is another important part of the process. The wrap applies gentle pressure to your injury. This pressure improves blood flow, helps your body remove waste, and reduces swelling. Here is a quick look at the benefits of compression:
|
Benefit |
Description |
|---|---|
|
Improved Circulation |
Helps blood carry oxygen and nutrients to the injured area for healing. |
|
Lymphatic Drainage |
Moves waste out of the area, reducing soreness and discomfort. |
|
Reduced Swelling |
Stops fluid from building up, which lowers stiffness and swelling. |
You get a more comfortable and effective recovery when you combine cooling and compression.
💡 Tip: Always follow your doctor’s advice for how long to use your cold therapy machine. Too much cold can harm your skin.
