How and when to use cryotherapy and heat therapy

To keep it simple, cryotherapy treatment is often used for swelling and pain from injuries.

Whereas heat treatment is often used for chronic pain, muscle spasms, and inflammation.

When should you use either one?

The best time to use cryotherapy and heat therapy depends on the type of injury or illness you are treating.

So, let’s break this down a little bit more!

Cryotherapy treatment

Cryotherapy is the process of using cold temperatures to treat injuries or sore muscles. 

Exposed to extremely low temperatures, it causes vasoconstriction and reduces inflammation.

Cryotherapy treatment is used immediately after injury to reduce pain and inflammation. It should be done for 10-20 minutes at a time, every 3-4 hours.

Heat treatment

Heat therapy, on the other hand, involves using warm temperatures to treat injuries or sore muscles. 

It enhances circulation by warming up the blood vessels and helps to reduce inflammation and pain. 

Heat treatment should be used on chronic or recurring injuries, or if you are recovering from surgery.

The benefits of heat therapy are that it is more economical, easier to apply and less likely to cause discomfort than cryotherapy. 

However, cryotherapy and heat therapy have combined benefits when used at various phases for things such as sprains, strains, muscle spasms, other soft tissue injuries and more.

Steps to treat an injury with cryotherapy and heat therapy

You’ve injured yourself and are probably in extreme agony, with severe swelling. 

You want relief and want it quick!

Here is some physiotherapy advice with steps for natural relief with cryotherapy and heat therapy.

Phase 1: Acute injury (1-5 days)

The first stage is an immediate response to injury or trauma. This includes inflammation, swelling, increased redness and pain, as well as decreased movement in the affected joints.

What should you use for acute injury? 

Cryotherapy treatment

Ice, a pack of peas (or sweetcorn if you prefer!), or even a gel pack. Whatever you have, get it on and let it get to work until it begins to feel numb but no longer than 20 minutes. 

If possible, elevating the injury will also aid in reducing the swelling and inflammation. See the RICE method.

Ice/ice pack should never be applied directly to the skin, on an open wound or bony part of the spinal column. Ensure you have a barrier/covering between the ice and your skin.

Phase 2: Subacute post-injury (3-8 weeks)

After a few days, the pain and swelling should be considerably less. At this stage, cellular generation and tissue repair are occurring.

However, you may still have trouble and discomfort when stretching the injury or using it in everyday activities.

You want to promote healing and have minimal scar tissue. What should you use for a subacute injury?

Cryotherapy and heat therapy

If you still have considerable redness or swelling apply cryotherapy treatment as instructed in the acute injury phase. 

If it has significantly reduced and you are experiencing pain outside your normal range of movement, then apply heat treatment for up to 20 minutes at a time, every 3-4 hours.

Make sure your heat pack is never applied directly to your skin and is at a bearable temperature to not cause further injury, burns or irritation.

Phase 3: Chronic post-injury (8 weeks +)

At this phase of inflammation, there’s continuous healing of damaged tissue. This can last up to several years!

Hence why, if not treated properly, many suffer from aches, pains, and complications from ‘old’ injuries.

To avoid this, seeking physiotherapy advice and treatment for chronic post-injury is advisable. 

In this phase, it's important to reduce the formation of scar tissue to ensure optimal healing. This can be done through various physiotherapy approaches and techniques.

But in the meantime, what can be used for chronic post-injury?

Heat treatment 

Apply heat treatment as described in the subacute phase to relieve aching and scar tissue formation. And ensure you receive physiotherapy treatment 1-2 times a month to reduce scar tissue and increase your strength, stability, and range of motion.

Use ‘new cold, heat old’ to remember when to use cryotherapy and heat therapy.
