Today we’ll focus on the following cold therapy machines:


What Are Cold Therapy Machines?

Ice therapy machines also known as cold therapy machines are used for cold compression therapy which utilizes the freezing effect in conjunction with compression. 

Cold therapy machines incorporate two aspects of the R.I.C.E healing and recovery method. This stands for Rest, Ice, Compression and Recovery; cold therapy machines focus on the Ice and compression phases. [1]

Cold therapy machines look similar to an ice cooler and utilizes freezing agents such as ice and water. They usually come with a hose; one side of the hose is attached to the container while the other end is attached to a circulation pad, which is placed on a section of the body.

When the ice and water are added to the container, you must then wrap the pad which is connected to the hose, around the body part that requires treatment.

The machine then disperses the cold therapy through the hose and on to the surface of the pad, which is wrapped around the knee, leg, shoulder or other body parts thus compressing the injury in the process.  

The compression aspect of the machine helps to remove fluid that has been built up in the area and caused the swelling. While the cold temperature narrows the blood vessels thus temporarily inhibiting blood flow to the injured area.

What are the Benefits?

Medical professionals, along with sports and rehabilitation specialists all agree that compression therapy in combination with cold therapy ranks among the best treatment for injury, inflammation and pain related to your muscular system. [2]

Cold compression therapy helps to mitigate pain, thanks to its numbing effect, and it does not have the dangerous side effects of over-the-counter medication.

It also helps your tissues repair themselves faster by reducing swelling and inflammation, and increasing nutrients and oxygen to the injured area.

Its other benefits include stimulating blood flow and stimulating the movement of lymphatic fluid which then provides injured tissues with both nutrients and oxygen.

What to Look for When Choosing a Cold Therapy Machine

If you’ve never bought one before and need further advice on choosing a machine, we have some useful information on what you should pay special attention to. 

Timer Setting

Some devices have to be timed within 15 or 30-minute increments, while others allow you hours of continued use.

Depending on your condition, you will need to utilize cold therapy for a specified time so this is an important feature to consider before you purchase.

Tube Dimension  

An extra-long tube allows you the flexibility to move around without having to lug the machine with you wherever you go. 

Another option is a detachable tube which allows you to remove it during use if you need to go somewhere.

Customizable Pads

Some pads are designed to be used only on specific areas such as the knee and won’t work on other body parts.

If you want a product that can be used on different areas, ensure that this is stated in the product description.

Motorized & Non-Motorized

A motorized device comes with a motor; thus the name, and it does have its benefits. These can send a stronger and more consistent flow of cold therapy to the injured area.

The downside is that they can be noisy, although some options boast ‘whisper quiet’ features.

The benefits of non-motorized machines are that they are quiet and are often light, making them a portable option if you want a machine that you can travel with.

Another great benefit is that there are no plugs, so you can use it any and everywhere.

These are usually very basic, however, so you won’t get the fancy timers, settings, or led screens that are available on some motorized models.

Weight and Size

These machines can weigh anywhere from 2-8 pounds since they differ in size, style and features.

The heavier ones are usually motorized, but this will only be an issue if you tend to move around a lot during use – and if the cord is not long enough for the item to stay in one place while you move.

Special Features

One of the machines on our list offers both a cold and heat therapy setting, so look out for special features like these which could be an added benefit to help your condition.  


Other Types of cold therapy units

Ice pack – This is a reusable packet that may contain gel or something similar. The pack must be frozen for a specified time, then it is placed directly on the swelling or painful area.

Coolants – These come in the form of sprays or ointments and are either rubbed into or sprayed onto the area to relieve pain. They have a cooling sensation, but don’t usually require refrigeration. 

Ice massage – This is performed using an ice cup which is placed on the injured area and gently rotated. This movement is said to mobilize soft tissues much like a regular massage, while the ice helps with pain. [3]


Before we go, it is always advisable that you consult a doctor before utilizing this type of therapy. NB. This is especially important if you suffer from a heart or cardiovascular related medical condition. 

A medical professional will be best able to indicate if cold therapy is the best course of action for your ailment, and will also determine the proper length of time you should use your machine each day.

Do not use the machine longer than the recommended time.

This is very important because cold therapy applied for extended periods can cause adverse issues such as nerve damage, tissue damage or skin damage.

Always read the instructions carefully so that your treatment is effective, and with proper and consistent use will soon start to reap the benefits of cold therapy.
