Cryotherapy, which literally means “cold therapy,” is a technique where the body is exposed to extremely cold temperatures for several minutes.
Cryotherapy can be delivered to just one area, or you can opt for whole-body cryotherapy. Localized cryotherapy can be administered in a number of ways, including through ice packs, ice massage, coolant sprays, ice baths, and even through probes administered into tissue.
The theory for whole-body cryotherapy (WBC) is that by immersing the body in extremely cold air for several minutes, you could receive a number of health benefits. The individual will stand in an enclosed chamber or a small enclosure that surrounds their body but has an opening for their head at the top. The enclosure will drop to between negative 200–300°F. They’ll stay in the ultra-low temperature air for between two and four minutes.
You can get benefits from just one session of cryotherapy, but it’s most effective when used regularly. Some athletes use cryotherapy twice a day. Others will go daily for 10 days and then once a month afterwards.
1. Reduces migraine symptoms
Cryotherapy can help treat migraines by cooling and numbing nerves in the neck area. One study foundTrusted Source 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.
