1. Reduces Migraine Symptoms
    Cryotherapy can help treat migraines by cooling and numbing nerves in the neck area. One study found that applying a neck wrap containing two frozen ice packs to the carotid arteries in the neck significantly reduced migraine pain in those tested. It’s thought that this works by cooling the blood passing through intracranial vessels. The carotid arteries are close to the skin’s surface and accessible.
  2. Numbs Nerve Irritation
    Many athletes have been using cryotherapy to treat injuries for years, and one of the reasons why is that it can numb pain. The cold can actually numb an irritated nerve. Doctors will treat the affected area with a small probe inserted into the nearby tissue. This can help treat pinched nerves or neuromas, chronic pain, or even acute injuries.
  3. Helps Treat Mood Disorders
    The ultra-cold temperatures in whole-body cryotherapy can cause physiological hormonal responses. This includes the release of adrenaline, noradrenaline, and endorphins. This can have a positive effect on those experiencing mood disorders like anxiety and depression. One study found that whole-body cryotherapy was actually effective in short-term treatment for both.
  4. Reduces Arthritic Pain
    Localized cryotherapy treatment isn’t the only thing that’s effective at treating serious conditions; one study found that whole-body cryotherapy significantly reduced pain in people with arthritis. They found that the treatment was well-tolerated. It also allowed for more aggressive physiotherapy and occupational therapy as a result. This ultimately made rehabilitation programs more effective.
  5. May Help Treat Low Risk Tumors
    Targeted, localized cryotherapy can be used as a cancer treatment. In this context, it’s called “cryosurgery.” It works by freezing cancer cells and surrounding them with ice crystals. It’s currently being used to treat some low-risk tumors for certain types of cancer, including prostate cancer.
  6. May Help Prevent Dementia and Alzheimer’s Disease
    While more research is needed to evaluate the effectiveness of this strategy, it’s theorized that whole-body cryotherapy could help prevent Alzheimer’s and other types of dementia. It’s thought that this may be an effective treatment because the anti-oxidative and anti-inflammatory effects of cryotherapy could help combat the inflammatory and oxidative stress responses that occur with Alzheimer’s.
  7. Treats Atopic Dermatitis and Other Skin Conditions
    Atopic dermatitis is a chronic inflammatory skin disease with signature symptoms of dry and itchy skin. Because cryotherapy can improve antioxidant levels in the blood and can simultaneously reduce inflammation, it makes sense that both localized and whole-body cryotherapy can help treat atopic dermatitis. Another study (in mice) examined its effect for acne, targeting the sebaceous glands.

Related Risks and Side Effects (according to Healthline.com):

The most common side effects of any type of cryotherapy are numbness, tingling, redness, and irritation of the skin. These side effects are almost always temporary. Make an appointment with your doctor if they don’t resolve within 24 hours.

You should never use cryotherapy for longer than is recommended for the method of therapy you’re using. For whole body cryotherapy, this would be more than four minutes. If you’re using an ice pack or ice bath at home, you should never apply ice to the area for more than 20 minutes. Wrap ice packs in a towel so you don’t damage your skin.

Those with diabetes or any conditions that affect their nerves should not use cryotherapy. They may be unable to fully feel its effect, which could lead to further nerve damage.
