Cryotherapy
Emerging evidenceWhy it might help
Applying cold to the neck over the carotid arteries is thought to cool passing blood and dampen some of the vascular changes and nerve (nociceptive) signaling involved in a migraine attack.
What the research shows
A small randomized controlled trial of targeted neck cooling reported reduced migraine pain during an attack, but the evidence comes from localized cold application rather than whole-body cryotherapy chambers, and studies remain small and short-term.

Frozen neck wrap targeting the carotid arteries produced a significant decrease in pain versus control (P<.001).
