Heat or Cold Therapy: Which One is Better?

As people’s living standards are getting higher and higher, heat or cold therapy often appears in people’s daily lives. Some people like cold therapy to restore their bodies, while others like heat therapy. Then, people will have a question: Is cold therapy better or heat therapy better? This article will introduce the benefits of heat or cold therapy, as well as a new therapy – hot/cold immersion therapy, to help everyone choose the right therapy according to their needs.

Heat or Cold Therapy

Cold therapy is a treatment method that uses low temperature to cool down body tissues to achieve treatment. Common cold therapy methods include ice packs, ice pads, ice baths, ice massage, etc.

Heat therapy is a treatment method that uses various heat sources as a medium to transfer heat to the body to achieve treatment. Common therapies for heat therapy include: hot water bag, infrared, wet heat compress, warm water immersion, sauna, etc.

Benefits of Heat or Cold Therapy

The benefits of heat and cold therapy are described below to help people understand them better.

Benefits of Heat Therapy

Control inflammation: Cold therapy can reduce the speed of nerve conduction and blood flow to muscles, thereby limiting the process of inflammation and swelling.
Relieve stress: Cold therapy activates the body’s stress response, leading to the release of cortisol, which has the effect of regulating microcirculation and maintaining blood pressure.
Enhance the immune system: Cold therapy can stimulate the body’s sympathetic nervous system and blood circulation, enhance immunity, and reduce the risk of infection.
Promote blood circulation: Cold therapy can promote blood circulation and accelerate metabolism.
Analgesia: Coldness reduces nerve excitability and slows down conduction speed, so it can relieve pain.

When Is Heat or Cold Therapy Suitable?

The suitable time of heat and cold therapy are described below to help people understand them better.

When Is Cold Therapy Suitable?

Acute injury: Cold therapy is more effective for acute injuries such as soft tissue contusion in local areas and swelling and pain in limbs caused by fractures. Patients using cold therapy can generally effectively prevent the swelling of limbs from worsening, and can also achieve local hemostasis.
High fever: Using ice packs or cold water towels to cool the head for high fever can reduce fever and temperature.

Acute inflammation: Cold therapy can treat some acute inflammations, shrink skin blood vessels, and limit the gradual spread of inflammation.

When Is Heat Therapy Suitable?

Lumbar muscle strain, renal colic, gastrointestinal spasm, sty, mastitis: Hyperthermia is very helpful for patients with these diseases and can help them relieve pain.

Common perineal and anal diseases and before and after surgery: Heat therapy can achieve the effects of anti-inflammatory, swelling, analgesia, local cleaning and comfort.
Of course, in addition to the above, heat therapy can be used for muscle pain, sleep quality problems, fatigue and anxiety problems.

Precautions for Heat or Cold Therapy

The precautions for heat and cold therapy are described below to help people understand them better.

Precautions for Heat Therapy

The treatment area has vascular diseases or defects. If there is a vascular disease, poor blood circulation will lead to poor heat dissipation ability of the tissue, which may cause burns.
Pay attention to control the temperature and time. Different heat therapy methods have different temperatures and times. Pay attention to confirm the temperature and time of heat therapy according to your physical condition and detailed consultation. During the heat therapy process, if you cannot detect the temperature change, it is possible that the temperature is too high but you don’t find it and get burned.

Precautions for Cold Therapy

People with the following contraindications are not suitable for cold therapy: heart dysfunction, arteriosclerosis, and vascular embolism.
Patients who are allergic to cold may experience rash, joint pain, muscle spasms, etc. after cold therapy.
Pay attention to controlling temperature and time: Different cold therapy methods have different temperatures and times. Pay attention to confirming the temperature and time of cold therapy according to your physical condition and detailed consultation.
Cold therapy cannot be performed on the back of the pillow, auricle, and scrotum, which can easily cause frostbite. In addition, the precordial area, abdomen and soles of the feet are areas that cannot be treated with cold therapy.

Hot/Cold Immersion Therapy: Combining Heat Therapy and Cold Therapy

In addition to cold therapy and heat therapy, there is another fitness method that is good for the body, that is, hot/cold immersion therapy, also known as contrast bath therapy. It refers to the method of alternating cold therapy and heat therapy, which is one of the special methods of hydrotherapy in physical therapy.

Benefits of Hot/Cold Immersion Therapy

Like the two separate methods of cold therapy and heat therapy, Hot/Cold immersion therapy also has a strong effect of exercising the body. The body alternates between hot and cold water, so that the body undergoes alternating stimulation of hot and cold. The alternating stimulation of hot and cold causes the blood vessels to expand and contract, thereby increasing the elasticity of the blood vessels and tolerance to stimulation, enhancing blood circulation, and promoting wound healing.

How to do Hot/Cold Immersion Therapy

The method of hot/cold immersion therapy is to soak the body in a hot water bucket for a few minutes after exercising, and then soak it in a cold water bucket for a few minutes. After alternating several times, it ends in cold water. Hot/Cold immersion therapyis often used to treat sports injuries, eliminate edema, and reduce soreness after exercise.
In addition, when performing hot/cold immersion therapy, you also need to pay attention to some issues. You can refer to the precautions for cold therapy and hot therapy for details and perform it while ensuring your own physical condition.

FAQ

The above article has a relatively comprehensive understanding of cold and heat therapy. Below are some common questions and answers to help people answer their inner doubts. If you have other questions not mentioned, you can comment in the comment area.

Are Cold Therapy and Heat Therapy the Same?

There are similarities and differences between the two. Both cool the body, but the temperature is different. The temperature of cold therapy is generally above 0℃, while the temperature used in cryotherapy is much lower than 0℃. Cryotherapy is mainly applied locally, while cold therapy is mainly applied locally or whole body.

Is Heat Therapy Effective for Chronic Pain?

It has a certain effect. Using continuous low-level heat therapy is helpful for relieving chronic pain, such as arthritis, sprains, muscle spasms, etc.

How Long Does Hot/Cold Immersion Therapy Take and What Is the Temperature?

Hot water is usually at a temperature of 37-40°C and lasts for about 3-4 minutes. Cold water is 10-15°C and lasts for about 1 minute. Repeat the cycle 3 to 4 times and end with cold water.

Heat therapy and cold therapy have different functions and different effects on the human body. Both cold therapy and heat therapy have their own advantages. Which therapy to take depends on people’s needs. People need to choose the therapy that suits them according to their own situation, or a combination of the two is also a good choice.
