In the world of biohacking, contrast therapy is one of the most popular options. It involves sitting in a sauna or warm shower/bath and then transitioning to a cold bath. Ideally, you go back and forth to improve circulation and accelerate muscle recovery. Many physical therapists and sports medicine specialists use this therapy, but a lot more facilities are becoming available to the general public.Â
According to research, contrast therapy can help reduce muscle spasms, pain, fatigue, lactic acid buildup, and swelling following intense exercise. It may also assist with functional mobility of joints and improve range of motion. In this article, we will explore how contrast therapy works and the standout benefits.Â
How Does It Work?
Contrast therapy involves alternating between warm and cold temperatures. The science is based on thermotherapy (using heat) and cryotherapy (using cold). The warmth of a sauna causes blood vessels to widen, while the cold of a plunge causes them to narrow. By going back and forth between the two extreme temperatures, you create a pumping effect within the body that may reduce inflammation. This process may also relieve pain and improve joint mobility.Â
Most people with soft tissue or joint injuries will benefit from contrast therapy. Some physical therapists also encourage contrast therapy to accelerate healing following orthopedic surgery. Other injuries that may benefit from contrast therapy include:
- Plantar fasciitis
- Dislocated elbow
- Ankle and leg fractures
- Torn meniscus
- Achilles tendonitis
- Anterior cruciate ligament (ACL) injuries
May Alleviate Pain And Accelerate Healing
A 2022 review of studies suggests that contrast therapy is highly effective at easing arthritis pain and stiffness. Researchers noted that it was more effective than a hot bath alone. The extreme cold works to block pain signals as well. Separate research found that it helps reduce muscle tension, inflammation, and accelerate recovery post-exercise. A 2018 study observed the effects of contrast therapy using infrared spectroscopy and other tools. Researchers found that it promoted healing by increasing oxygen delivery to bodily tissues, while also decreasing tissue swelling.
Helps Enhance Circulation
The heat component of contrast therapy works to increase blood flow. As mentioned earlier, blood vessels expand in the heat, allowing more blood to enter your muscles and supply them with minerals and oxygen. Oxygen serves as fuel for the muscle repair process, while the nutrients encourage robust, healthy muscle tissue. Your muscles are not the only things receiving more nutrients and oxygen during contrast therapy. It also aids the transfer of immune cells and other restorative components to wounded tissues. Enhanced circulation also works to regulate body temperature.Â
Improved Range Of Motion
Contrast therapy works to enhance range of motion in two ways. The cold plunge works to reduce inflammation and enhance joint mobility, while the sauna helps relax muscles and increases suppleness. Doing so can help you have more flexibility and mobility, making your body more able to do workouts with better form. That ultimately lowers your risk of injury and can help enhance overall performance.Â
Mental Rejuvenation
The benefits of contrast therapy extend beyond the physical. The unique combination of alternating between cold and hot temperatures can have positive effects on your mental health. Going back and forth between the two extremes helps recharge your mind and emotions. Ultimately, you will think more clearly and benefit from stress reduction, giving you an overall happier disposition.
Injury Prevention
Pushing yourself during a workout is great, but it can also increase your risk of injury. Contrast therapy positively impacts the body’s connective tissues, the strong network that supports muscles and joints. By strengthening the body’s support system, you can enhance your recovery regimen. Strains, sprains, and other injuries are less likely to occur in people who have stronger, more flexible connective tissues. The reason for that is because they can withstand the demands of training harder.
