Differences between cold therapy and hot therapy

Cold therapy and heat therapy are two popular methods of treating injuries or chronic pain. Cold therapy is typically used to reduce swelling, pain, and inflammation, while hot therapy is used to increase blood flow and promote healing through tissue relaxation.

Cold therapy, also known as cryotherapy, involves applying ice or a cold compress to the affected area. The cold helps decrease blood flow to the area, reducing inflammation, swelling, and pain. It also numbs the area, which can relieve pain and discomfort. Cold therapy is often used for acute injuries, such as sprains or bruises, and is usually done by alternating between 15 minutes of ice and 15 minutes without ice for 1.5 hours at a time, several times a day.


What types of ailments are best treated with ice?

Cold therapy is generally used as the first treatment for acute injuries caused by sprains, strains, sprains and muscle strains. When ice is applied to an acute injury, it can help reduce inflammation by inhibiting the transfer of glucose to active inflammatory cells. It can also help decrease pain by blocking certain sensory nerves.

Cold treatment is also recommended for chronic muscle tension because it slows down the inflammatory process that produces swelling and can reduce the intensity of pain. However, the use of cold should not be excessive as this may lead to lack of oxygen and compromise tissue healing.

What precautions should be taken when applying ice?

When applying ice to an acute injury, it is important to wrap the frozen product carefully in a wet, soft cloth to prevent the skin from freezing. One should also check the temperature of the frozen product frequently by touching it with one's hand to strategically scan its surface.

It is important to consult a physician before using heat treatments on sensitive areas such as joints or around vital organs. Care should also be taken to ensure that the treatment does not cause persistent numbness or tingling as this could mean overuse of heat treatment or too long exposure to frozen products.


Heat treatment

On the other hand, hot therapy, also known as thermotherapy, involves applying heat to the affected area. The heat helps increase blood flow to the area, which can promote muscle healing and relaxation. It can also relieve muscle stiffness and tension. Heat therapy is often used for chronic conditions, such as arthritis or back aches, and is usually done for 20 to 30 minutes at a time, several times a day.


Heat Therapy


What types of conditions are best treated with heat?

The conditions that generally respond best to heat therapy are those where there is a chronic musculotendinous problem such as joint and muscle pain, arthritis and tendonitis. Diseases such as osteoarthritis, osteoarthritis, and bursitis can also be effectively treated using this therapy as it will improve blood circulation to those painful areas.

Heat can also help relieve some more specific conditions such as neck and headaches related to stress and pressure points, such as migraine headaches or due to a stiff muscle. The heat will also soothe contracted muscle which can lead to soreness in the legs or back after strenuous physical exertion or any other prolonged physical activity.


What precautions should be taken when applying heat?

Before using heat-based heat treatments, it is important to consult with a medical professional. It is also important to use an appropriate heat source suitable for your condition.

Heat must be applied but without overdoing it, making sure that the heat treatment does not cause irritation or redness on the skin. The temperature chosen for the treatment must be low enough to avoid any burns and be bearable by the patient.

In summary, cold therapy is used to reduce inflammation and swelling, while hot therapy is used to increase blood flow and promote relaxation. Both methods can be effective in treating pain and injury, depending on the situation.



Ice constricts blood vessels, which numbs pain, relieves inflammation and limits bruising.


Heat increases blood flow, which relaxes tense muscles and relieves stiff joints.


Herniated disc, bulging disc or pinched disc. Osteoarthritis of the spine. BACK PAIN The ice dulls the inflammation and numbs the pain.
Worn cartilage in the joints (knee, shoulder, elbow, fingers, etc.). ARTHROSIS - ARTHRITIS The moist heat relieves joint stiffness and relaxes tense muscles.
Nerve or blood vessel pain in the head

or muscles in the neck.

HEADACHE - NECK Ice relieves nagging headaches.

The moist heat relaxes the muscle spasms in the neck.

Stretched muscles or injured tendons in the thigh, calf, back, etc. STRAIN Heat reduces stiffness after inflammation has subsided.
Stretching or tearing of ligaments in joints such as the knee, ankle, foot, elbow, etc. SPRAIN The ice dulls the inflammation and numbs the pain. Heat reduces stiffness after inflammation has subsided.
Acute irritation, following an activity, of the tendons attached to the joints such as the shoulder, elbow, knee, wrist, heel, etc. TENDONITIS - BURSITIS The ice dulls the inflammation and numbs the pain.
Chronic inflammatory arthritis (big toe, instep, ankle, heel, knee, wrist, finger, elbow, etc.) ACHE The moist heat relaxes muscle spasms and reduces pain.



  • Apply ice for 15 minutes then remove for 15 minutes and reapply, alternately, for one and a half hours.


  • Do not use heat for acute injuries (48 hours). It increases inflammation and can delay healing. When in doubt, use ice!
  • Use ice immediately after an injury to reduce inflammation.
  • Do not use heat on an injury that is already warm to the touch.
  • It is recommended never to apply ice or heat in the following cases: severe circulatory problems, significant decrease in sensitivity, heart problems, taking medication affecting judgment (danger of burning), malignant tumor (cancer) or on burned skin.
