Physio Bangkok is receiving more queries about when to use heat or cold for their injuries. The confusion is understandable as many tend to reach out to social media channels and not knowing the difference between hot and cold exposures to sprains, strains and injuries of any kind.
Not only do physiotherapists often use hot or cold packs as part of their treatment plan to manage pain and inflammation; the general public seems to have a lot of misconceptions about when to use a hot pack or a cold pack. Let’s raise the benefits and drawbacks of applying heat and cold, and provide examples of injuries when each method is appropriate.
Let’s summarise the topic at large here.
Ice packs are typically used in the acute phase of an injury or inflammation. They can help to reduce swelling and pain by constricting blood vessels and slowing down the inflammatory process. Ice packs are often used for injuries such as sprains, strains, and bruises. Advantages to cold therapy is the reducing effects of inflammation, it has a numbing effect, and cold packs can prevent or reduce swelling.
On the flipside, prolonged exposure to cold can damage the skin or cause frostbite, and can cause muscle stiffness and reduce range of motion in some cases. We also do not recommend cold therapy for chronic conditions, as it can cause further tissue damage.
A review published in the Journal of Emergency Medicine found that cold therapy can be effective in reducing pain and swelling in acute musculoskeletal injuries. The authors noted that cold therapy is a safe and inexpensive treatment option that can be easily applied at home.
Hot treatments are typically used in the sub-acute or chronic phase of an injury or inflammation. They can help to promote blood flow, relax muscles, and relieve pain. Hot packs are often used for conditions such as muscle spasms, stiffness, and chronic pain. Some of the advantages are seeing an increase in blood flow, it has more relaxing tendencies for tight muscles and stiffness, and it has shown to be beneficial for those with chronic conditions.
Some of the disadvantages of hot treatments lie in the potential swelling of acute injuries, the higher risk of bleeding and bruising (particularly when the injury is near the skin). Additionally, prolonged exposure to heat can lead to burns or skin damage.
A study published in the Journal of Sports Science and Medicine found that heat therapy can be effective in reducing muscle soreness and improving muscle function in athletes after exercise. The authors noted that heat therapy can also promote tissue repair and regeneration.
It’s important for clients to apply the right stimulus – be it hot or cold – on the appropriate use of such therapies and to address any misconceptions they may have. This will help ensure that clients get the most benefit from their treatment plan and avoid any potential harm.
Aside from other crucial aspects of seeing your discomforts and pains fade away, always consider including activities such as controlled movement and potential stretching, as well as implementing periods of rest and recovery in speeding up the process.
It’s important to note that hot or cold therapy should always be used under the guidance of a healthcare professional, as they can determine the best approach for each case. Improper use of hot or cold therapy can lead to further injury or aggravate existing conditions.
