The benefits of cryotherapy: a cold therapy method


Cryotherapy, a therapeutic method using cold, is growing in popularity among top athletes, amateurs and people suffering from chronic pain. This ancient approach, dating back to antiquity, offers many benefits for the body and health. In this article, we will explore in detail the different aspects of cryotherapy, including its definition, mechanisms of action, local and global benefits, sports indications and the different techniques used.

Cryotherapy: definition and techniques

Cryotherapy, which literally means "cold therapy", encompasses various techniques used in physiotherapy, traumatology, dermatology and aesthetic medicine. These techniques can be local, targeting a specific area of ​​the body, or global, involving the treatment of the whole body with cold. Each technique has specific benefits and indications.

Mechanisms of action of cryotherapy

The principle of cryotherapy is based on the application of cold to the area to be treated, which causes vasoconstriction, ie a reduction in the caliber of blood vessels. This phenomenon helps to reduce bruising and pain. For example, applying ice immediately after a sports injury helps reduce inflammation and limit the occurrence of edema. In dermatology, cryotherapy uses very low temperatures, usually through liquid nitrogen, to treat skin conditions such as warts and warts.

To be effective, cryotherapy must respect the principle of thermal shock , which combines two essential elements: a rapid lowering of the temperature of the skin to less than 15 degrees, followed by a short-term action generally not exceeding 10 to 15 seconds.

Benefits of cryotherapy

The benefits of cryotherapy are numerous and vary depending on the technique used, whether local or global.

Benefits of cryotherapy in local application:

  • Pain reduction: Cold slows nerve conduction and increases the threshold of pain sensory receptors, which helps relieve painful sensations.

  • Relief of inflammation: The immediate vasoconstriction caused by the cold helps to quickly stop the inflammatory reaction and limit the formation of edema. Subsequently, the cold causes vasodilation, favoring the drainage of the blood and lymphatic system, which contributes to the healing of edema and the reduction of inflammation.

  • Promoting recovery: By increasing blood flow in the treated area, cryotherapy allows the body to more effectively eliminate lactic acid accumulated during physical exertion. This improvement in blood circulation thus promotes better recovery, notably reducing muscle pain.

Benefits of cryotherapy in global application:

  • Improved respiratory function: The cold causes mild bronchodilation through the reaction of the sympathetic nervous system, which helps to improve respiratory capacity.

  • Boosting the immune system: Studies have shown an increase in certain markers of immunity after regular cold baths. Thus, cryotherapy can help prevent common disorders during the winter season such as angina and bronchitis.

  • Benefits for the muscles: The increase in blood flow and heart rate during exposure to cold promotes drainage, muscle oxygenation and better elimination of toxins.

  • Improvement of the quality of the skin: Thanks to the increase in the cutaneous microcirculation, cryotherapy contributes to make the epidermis firmer and toned, thus improving the quality of the skin.

By acting on the nervous system, cryotherapy also has beneficial effects on stress, anxiety and sleep disorders.

Sports indications for cryotherapy

Cryotherapy is widely used in the field of traumatology and sports medicine, especially by top athletes. It has benefits for all aspects of sports practice, from training preparation to recovery, injury prevention and healing. This is why health professionals who accompany athletes, such as sports doctors and specialized physiotherapists, often recommend it.

Recovery :

After intense physical exertion, muscles accumulate toxins that can cause pain if not eliminated properly. Whole body cryotherapy stimulates blood circulation by increasing heart rate and alternating between vasodilation and vasoconstriction. This stimulation promotes oxygenation of the muscles, reduces inflammation, aches and other pains, thus improving muscle recovery.

Prevention and healing of injuries:

Cryotherapy contributes effectively to the prevention of sports injuries by limiting aches and inflammations resulting from shocks and falls during physical activity. In addition, it can accompany and accelerate the healing of certain injuries. Among the injuries for which cryotherapy can be beneficial, we find muscle micro-traumas, muscle tears and strains, sprains, tendinopathies and certain fractures. Although it is not a full-fledged treatment for these injuries, cryotherapy promotes healing, reduces symptoms such as swelling and pain, and speeds up the healing process.

Physical preparation and athletic performance:

By improving recovery, cryotherapy allows athletes, whether amateur or high-level, to resume training more quickly while optimizing their performance. Cryotherapy sessions are beneficial after exercise (training and competition) by reducing pain and promoting muscle recovery. They can also be used before training to soothe possible pain and prepare the body for the effort to come.

The different cryotherapy techniques

Cryotherapy offers different forms of treatment, adapted to the specific needs of each situation.

Local treatment:

This technique is commonly used in trauma and sports medicine to target specific injuries such as sprains, tendonitis and bursitis. It consists of applying cold directly to the affected area. Several methods are used, including the direct application of ice, the use of ice packs or cryogel (gel placed in the freezer), as well as the use of cryogenic sprays.

Cold baths:

Cold baths are widely used by top athletes for physical recovery. They consist of immersing yourself in a bath of cold water at a temperature of around 10°C for at least 10 minutes. Immersion can be continuous or discontinuous depending on preferences and needs. This method is becoming increasingly popular. Indeed it is easy to acquire a portable ice bath nowadays at affordable prices in order to be able to practice this practice at home with ease, whether you live in a house or in an apartment, the ice bath is the ideal solution.

Whole body cryotherapy:

This form of cryotherapy takes place in a specially designed chamber or cabin. The person is exposed to extremely low temperatures, generally around -110°C, for less than 3 minutes. Specific equipment such as socks and gloves are used to protect the extremities of the body.

Whole body cryotherapy is used not only for athlete recovery and preparation, but also to treat chronic conditions such as rheumatism, sleep disorders and fibromyalgia.


Cryotherapy offers many benefits for the body and health. Using cold as a therapeutic method, it reduces pain, relieves inflammation, promotes muscle recovery, improves respiratory function, strengthens the immune system, improves skin quality and contribute to the prevention and healing of sports injuries. Whether through local treatment, cold baths or whole body cryotherapy, each technique offers specific advantages.

It is important to note that cryotherapy is not suitable for everyone. Some contraindications, such as high blood pressure, wearing a pacemaker, Raynaud's syndrome, sensitivity disorders and kidney disease, must be taken into account. It is recommended to consult a healthcare professional before using cryotherapy to ensure that it is suitable for your specific situation.

In conclusion, cryotherapy is an effective therapeutic method using cold to bring many benefits to the body and health. Whether you are an athlete looking to improve your recovery and performance, or someone suffering from chronic pain, cryotherapy can be an interesting option to consider. Nevertheless, it is essential to consult a qualified health professional to determine if cryotherapy is suitable for your particular case.
