Targeted cold, with a solid case for pain and a genuinely weak one for healing
Cold reduces the temperature of the tissue underneath it. That drop slows nerve conduction velocity in the area, raising the threshold at which a pain signal registers. It also narrows local blood vessels, reducing blood flow to the region while the cold is applied. Both effects are immediate, both are measurable, and both reverse as the tissue rewarms.
The pain effect is the one that survives scrutiny in humans. It is not subtle and it is not placebo: slowing the signal produces real, short-lived relief. That is why cold has been standard practice on sidelines for decades and why it remains reasonable for exactly that purpose.
The second half of the traditional story is that cooling limits secondary tissue damage and helps the area repair faster. That part has not been demonstrated in people. It comes from animal models, and some of those same models point the other way, suggesting prolonged cooling can interfere with the inflammatory processes that muscle and tendon regeneration depend on. Cold is a good analgesic with an unproven repair story attached.
Reach for cold when pain is the problem you are solving: an acute knock, a flared-up joint, or an area sore enough it is limiting what you can do. The early hours after an acute injury are where the case is strongest. Harder to justify is aggressive routine cooling of every session, because the mechanism that makes cold appealing, damping the inflammatory response, is the same one adaptation runs on, and the evidence against that being harmless is animal work rather than nothing. If a session was meant to make you fitter, there is a real argument for leaving it alone.
The evidence
Graded honestly. Where a finding argues against the way this service is usually sold, it still gets printed.
Cold produces genuine short-term pain relief after injury or exercise.

The caveat: The relief is short-lived and it is analgesia, not repair. Blunted pain can also let you load something harder than it is ready for, so the window right after cold is the wrong time to test how an injury feels.
Cold has not been shown in humans to limit secondary tissue damage or improve tissue regeneration.

The caveat: The review found no human evidence for either claim. Current understanding rests on animal models, and some of that work points toward cooling disrupting the macrophage activity and tissue clearance regeneration relies on. Treat the healing narrative as unproven.
The most defensible window for cold after an acute injury is early and short.

The caveat: The review suggests cold within roughly the first six hours for pain, and caution about continuing well past twelve hours because of the animal evidence on healing interference. That is a reasoned position drawn from mixed data, not a validated protocol.
