When an individual sustains an injury, their body attempts to heal itself by sending different cells to the injured area. These cells try to limit blood and fluid loss which in turn causes inflammation and pain. The five signs of inflammation are redness, heat, swelling, pain and loss of function.
What Does Ice Do?
Ice is a modality that can be used in order to prevent or slow down inflammation. When an individual applies ice to their injured area, it will decrease the tissue temperature causing a reaction from the body to protect itself against the cold. The smooth muscles around the cold will contract which will cause the blood vessels to narrow (vasoconstriction). In turn, this will reduce blood flow to the area.
Ice also helps to reduce an individual’s pain. Pain is a signal that gets transmitted to the brain by different pathways in the body. This signal gets activated at the area of injury, travels to the spinal cord and then travels up to the individual’s brain. Ice can help modify this signal by blocking the pain signal at the spinal cord and allowing the individual to focus on another stimulus, i.e. the ice.

What Does Heat do?
Heat is a modality used to help speed up healing and/or help with an individual’s pain. Heat increases the temperature of the tissues which causes relaxation of the smooth muscles. This causes the blood vessels to open up (vasodilation) and increases blood flow. Increased blood flow will help to accelerate healing because blood will bring oxygen to the tissues and bring the necessary healing cells to the area.
Heat also helps to reduce an individual’s pain as it modifies the perception at the level of the spinal cord and distracts the individual from their pain.
Heat also helps to increase range of motion and decrease stiffness as it helps to relax muscles and increases their extensibility/elasticity.
When Should I use Heat?
How Long Should I use Heat?
If you are using ice for a healing modality, it should be applied when there is a lot of inflammation or at the beginning of the injury process (the first 1-3 days).
If you are using heat for a healing modality, it should be used when the area has decreased blood supply, is stiff, or has signs of chronic inflammation. It should NOT be used in the first 48-72 hours of an injury or when there is a lot of swelling and inflammation in the area.
If an individual is using ice or heat for pain management, the choice is up to the individual. Both ice and heat modify the signal at the spinal cord in the same way, therefore the patient can use which modality they enjoy more.
Definitely! If you are starting new exercises to your injured area and feel the area is aggravated or there is an increase in inflammation, you can apply ice for 10 minutes to slow down the inflammation. Immediately follow with heat for 10 minutes to relax the area and increase blood flow.

This patient came in with a painful and disturbing clunking sensation while reaching overhead. With his consistency you can see his progress through his injury rehabilitation.
Many people don’t realize that they can come in BEFORE they have pain. You don’t have to wait until the pain effects your quality of life to come to physio.
