When it comes to enhancing the recovery and healing process after workouts, injuries and surgery, is it better to use hot (Thermotherapy) or cold (Cryotherapy) therapy?
It depends.
First, one of the benefits of utilizing both Cryotherapy and Thermotherapy for recovery and healing purposes is that in its various forms, it’s a non-evasive, drug-free way to help relieve pain and swelling while promoting the recovery and healing processes.
Before we dig deeper into this topic, here are a few general rules and recommendations.
Recommended:
Cryotherapy is used immediately after an injury to reduce inflammation
Thermotherapy is used to relax and sooth sore, stiff muscles and to increase range of motion
Not Recommended:
Cryotherapy is not recommended for stiff or tight muscles and joints.
Thermotherapy is not recommended on an injury that is already warm to the touch.
People with diabetes or other sensory conditions, injuries or issues that prevent them from feeling certain sensations in the extremities or other parts of the body should not use Cryotherapy or Thermotherapy in any setting where a qualified healthcare professional is not actively monitoring or available. This is primarily because patients with certain conditions, injuries or issues that cause a lack of adequate feeling or sensory perception are at risk of further injury.
Thermotherapy should be avoided if the area being treated is either bruised or swollen, or on open wounds.
Patients with heart disease or hypertension should consult a qualified health care professional before use of Thermotherapy.
Patients with following health conditions should also avoid Thermotherapy because of the increased risk of burns or additional complications:
Dermatitis
Diabetes
Deep Vein Thrombosis
Multiple Sclerosis(MS)
Vascular diseases
Thermotherapy
Thermotherapy is primarily used for reducing several different kinds of body pain.
Dull, persistent pains that accompanies stiffness and cramping.
Post exercise soreness after a hard workout or exercise program.
DOMS, (Delayed Onset Muscle Soreness), is the pain that arrives 24-48 hours after exercising.
Thermotherapy can be an effective treatment to relax muscles, helping to increase range of motion.
Thermotherapy has been shown to be effective with stiffness and pain in specific areas or joints from conditions like osteoarthritis, muscle soreness from cramps and spasms.
Thermotherapy works by relieving pain, reducing muscle spasm and improving circulation to the injured area.
Thermotherapy is able to carry the heat in to the tissue to the depth of around two centimeters depending on the method and the body part being treated.
In general, when heated, a dilation of the blood vessels in the muscle tissue occurs, increasing the flow of nutrients and oxygen, promoting the healing process.
Here are some of the benefits associated with thermotherapy:
Pain Relief: Heat therapy can help alleviate muscle pain, stiffness, and tension by increasing blood flow to the affected area, relaxing muscles, and reducing stiffness.
Improved Flexibility: Applying heat to muscles and joints can help improve flexibility and range of motion, making it beneficial for athletes, individuals with arthritis, or those recovering from injuries.
Reduced Inflammation: Heat therapy can help reduce inflammation by dilating blood vessels, increasing circulation, and promoting the removal of waste products and toxins from tissues.
Relaxation and Stress Reduction: Heat therapy promotes relaxation by soothing tense muscles and reducing stress levels. It can also trigger the release of endorphins, which are natural pain-relieving and mood-enhancing chemicals.
Enhanced Healing: Heat therapy can accelerate the healing process by increasing the delivery of oxygen and nutrients to injured tissues, promoting cell regeneration, and speeding up the removal of metabolic waste products.
Improved Blood Circulation: Heat therapy helps dilate blood vessels, leading to improved circulation throughout the body. This can benefit overall cardiovascular health and promote the delivery of essential nutrients and oxygen to cells and tissues.
Muscle Relaxation: Applying heat to tight or spasming muscles can promote relaxation and reduce muscle tension, helping to alleviate discomfort and improve mobility.
Treatment for Certain Conditions: Thermotherapy is commonly used as a complementary treatment for various conditions, including muscle strains, arthritis, fibromyalgia, menstrual cramps, and chronic pain conditions.
It's essential to use thermotherapy safely and appropriately, as excessive heat or prolonged exposure to heat can lead to burns, dehydration, increased inflammation or other adverse effects. Always follow the instructions provided with Thermotherapy devices and consult with a healthcare professional if you have any underlying health conditions or concerns.
Thermotherapy Summary:
The use of heat for therapeutic purposes has been practiced for thousands of years across different cultures. Like cryotherapy, it has ancient roots and a long history of use in various forms.
Ancient civilizations such as the Greeks, Romans, Egyptians, and Chinese all used heat therapy for medicinal purposes. They employed methods like hot baths, hot stones, heated sand, and thermal springs to treat various ailments and promote healing.
In more recent history, heat therapy gained traction as a recognized medical treatment in the 19th and 20th centuries. Physicians began to systematically study and document its effects on the body, leading to the development of more sophisticated heat therapy techniques and devices.
Today, thermotherapy encompasses a wide range of modalities, including hot packs, warm baths, heating pads, heated blankets, infrared therapy, and more. It's used for pain relief, muscle relaxation, improved circulation, and various medical conditions, ranging from muscle strains and arthritis to chronic pain and stress management.
Overall, thermotherapy has a rich history spanning millennia and continues to be an essential part of both traditional and modern medical practices worldwide.
Cryotherapy
Cryotherapy is used during the early stages of sub-acute and acute injuries such as ankle sprains, muscle strains, bruising and inflammation.
Cryotherapy reduces blood flow. This reduction in blood flow limits the amount of fluid that is able to pool around the injury, which helps minimize swelling and bruising.
Cold therapy also helps to numb the nerve endings which decreases messages sent to the brain by the pain receptors.
Cold therapy should typically be used for three to five days following an injury utilizing the RICE protocol – rest, ice, compression and elevation.
Also, it should be noted that cryotherapy products should never be directly applied directly to the skin. A thin cloth or fabric barrier should be used to provide a layer of protection between the skin and the cryotherapy product in use.
Cold therapy should be used for short periods of time, several times a day. Periods of 10 to 15 minutes are usually best depending on the size of the body part being treated. Treatment periods over 20 minutes increase the possibility of nerve, tissue or skin damage.
Some of the commonly cited benefits of Cryotherapy:
Pain Relief: Cryotherapy can help alleviate muscle pain, soreness, and inflammation, making it popular among athletes recovering from injuries or intense workouts.
Reduced Inflammation: The extreme cold triggers vasoconstriction, reducing blood flow to the affected area and decreasing inflammation, which may benefit conditions like arthritis or tendonitis.
Improved Recovery: Athletes and fitness enthusiasts often use cryotherapy to speed up muscle recovery and reduce downtime between workouts.
Boosted Metabolism: Some proponents claim that exposure to cold temperatures can increase metabolism and aid in weight loss efforts.
Enhanced Mood: Cold exposure may trigger the release of endorphins and other mood-boosting chemicals, leading to improved mood and reduced feelings of stress or anxiety.
Skin Benefits: Cryotherapy can stimulate collagen production, resulting in tighter, smoother skin. It may also help reduce the appearance of cellulite and promote overall skin health.
Potential Treatment for Certain Conditions:
Cryotherapy is being studied as a potential treatment for various conditions, including certain types of cancer, autoimmune disorders, and even mental health issues like depression and anxiety.
Additionally, individual responses to cryotherapy can vary, so it's essential to consult with a healthcare professional before incorporating it into your routine, especially if you have any underlying health conditions.
Cryotherapy Summary:
Cryotherapy, in various forms, has been used for centuries, with records of its application dating back to ancient civilizations. Ancient Egyptians, Greeks, and Romans reportedly used cold therapy to treat injuries and reduce inflammation. They applied cold substances like snow, ice, and cold water to the body to relieve pain and promote healing.
In more recent history, the development of modern cryotherapy techniques began in the 20th century. The concept of localized cold therapy gained traction in the medical community, leading to the invention of devices like ice packs and ice baths for therapeutic use.
Whole-body cryotherapy (WBC), which involves exposing the entire body to extremely cold temperatures for a short duration, gained popularity in the late 20th century. The first modern WBC chamber was reportedly developed in Japan in the late 1970s by Dr. Toshima Yamaguchi for the treatment of rheumatoid arthritis.
Since then, cryotherapy has evolved, and various forms of cryotherapy, including whole-body cryotherapy, localized cryotherapy, and cryosurgery, have been used for medical, therapeutic, and cosmetic purposes. While it has ancient roots, cryotherapy in its modern forms has been in use for several decades, continually evolving as new technologies and applications are developed.
For further information, you will find a significant number of studies and research projects related to Cryotherapy and Thermotherapy are available on PubMed.
