Cryotherapy, which involves exposing the body to freezing or near-freezing temperatures, encompasses a range of treatments with potential physical and mental health benefits. It includes targeted therapies like cryoablation for specific medical purposes and broader applications such as whole-body cryotherapy (WBC) in wellness contexts. Here’s a closer look at the benefits, applications, and considerations for cryotherapy.
What is Cryotherapy?
Cryotherapy treatments use extreme cold to target various health concerns. These treatments include:
- Targeted Cryotherapy: Medical procedures that use controlled cold exposure to remove warts, skin tags, or abnormal tissues. It’s also employed in treating certain cancers.
- Whole-Body Cryotherapy (WBC): A wellness therapy where individuals expose their entire body to temperatures as low as -200°F for short periods. People claim WBC can boost physical recovery, enhance mental well-being, and potentially extend lifespan.
What Happens During a Cryoablation Procedure?
During cryoablation, doctors use real-time imaging, such as ultrasound or CT scans, to precisely guide a thin, needle-like probe into the tumor. Once positioned, the probe is cooled to sub-freezing temperatures, forming an ice ball at its tip. This ice ball freezes and destroys the cancerous tissue by disrupting its cellular structure.
The procedure is typically performed under general anesthesia. While many patients spend one night in the hospital, some may be discharged on the same day, depending on their recovery. Most individuals can resume walking within a few days, with full recovery generally occurring within two to three weeks.
Potential Benefits of Cryotherapy
1. Lesion Removal Targeted cryotherapy effectively removes skin lesions and small abnormal growths. Conditions treated include:
- Skin tags, warts, verrucas, and seborrheic keratosis.
- Certain cancers, such as basal cell and squamous cell carcinomas, retinoblastoma, and early-stage liver or prostate cancer.
Cryosurgery offers a less invasive alternative to traditional surgical methods. However, its long-term efficacy for cancer treatments remains under study.

2. Muscle Recovery Cryotherapy has long been associated with muscle recovery and pain relief. Applying cold therapy, such as ice packs, can reduce inflammation and improve blood flow, aiding healing.
- A 2017 review found positive effects of WBC on inflammatory markers after exercise.
- However, a 2019 study indicated no conclusive benefit to athletic performance, although a 2021 study noted potential benefits for muscle growth.
3. Cognitive Function Emerging research suggests cryotherapy may enhance cognitive performance:
- A 2021 trial found it improved cognitive markers and showed promise in managing mild cognitive impairment.
- A 2018 study indicated positive effects on memory retention, suggesting potential for preventing cognitive decline.
4. Mental Health: Anxiety and Depression Cryotherapy may improve mental well-being. A 2020 study found participants reported better mood, reduced depression symptoms, and improved quality of life after WBC compared to a control group.
5. Eczema Symptom Relief Some evidence suggests cryotherapy might alleviate symptoms of eczema, such as intense itching and dry skin patches. A 2021 study highlighted its potential, but further research is required to confirm its effectiveness.
Applications in Medical and Wellness Contexts
- Medical Use: Doctors recommend targeted cryotherapy in outpatient or hospital settings for suitable candidates. These procedures are well-tolerated and effective for localized treatments.
- Whole-Body Cryotherapy: WBC, often offered in spas or wellness centers, involves brief sessions in cold chambers or pods. While it is not FDA-approved or endorsed by dermatologists, anecdotal claims suggest benefits for physical and mental health.
Risks and Side Effects
While cryotherapy can offer benefits, it comes with risks:
- Common side effects include frostbite, rashes, swelling, and skin discoloration.
- Certain populations, such as pregnant women, children, and individuals with heart conditions or high blood pressure, should avoid WBC.
Considerations for Safety and Efficacy
- Evidence: While targeted cryotherapy for lesion removal has established medical backing, evidence for WBC’s broader benefits remains anecdotal or preliminary.
- Not a Replacement: Cryotherapy should not replace conventional medical treatments but may complement them under professional guidance.
Summary
Cryosurgery, also referred to as cryotherapy or cryoablation, is a medical procedure that utilizes extreme cold, typically generated by liquid nitrogen or argon gas, to destroy abnormal tissues, including cancer cells. As a localized treatment, cryosurgery targets a specific area of the body without affecting surrounding healthy tissue.
This technique is commonly employed to treat tumors on the skin, such as warts, skin tags, and certain precancerous conditions. Additionally, cryosurgery is effective for addressing specific internal tumors in organs like the liver, prostate, and lungs, depending on the patient’s condition and the type of abnormal tissue.
By leveraging precise and controlled freezing, cryosurgery provides a minimally invasive option for patients, offering reduced recovery times and fewer complications compared to traditional surgical methods.
Cryotherapy offers diverse potential benefits, from lesion removal to supporting muscle recovery, mental health, and cognitive function. While targeted treatments have proven efficacy, the claims around whole-body cryotherapy require more robust scientific validation. Anyone considering cryotherapy should consult healthcare providers to weigh its risks and benefits, ensuring it aligns with their health needs and goals.
