Brief exposure to very cold dry air in a chamber or cabin, distinct from a cold-water plunge.
What it is, why people use it, the evidence, and what to know before trying it.
Cold air lowers skin temperature and changes thermal sensation. Claims about improved recovery depend on clinical comparisons, not the chamber’s displayed air temperature.
Regulatory status: Therapeutic claims and device authorization depend on the specific device and jurisdiction; no approval is assigned to an unspecified chamber.
Evidence basis: Human clinical evidence
A Cochrane review found very uncertain evidence for exercise soreness and subjective recovery, mainly in young men. That evidence does not establish benefits for women, elite athletes or a specific chamber schedule.
Confidence: weak
Situations where this practice may need modification or professional guidance.
Extreme cold can injure skin and requires appropriate screening and supervision. Small exercise trials provide inadequate safety reporting; nitrogen-based and electrically cooled systems have different operational risks.

Session and schedule patterns reported in public protocols; these are observations, not instructions. Private and hidden usage is excluded.
