Treatment & self-care
Heat, cold and spray-and-stretch: when each one helps
Temperature is a way to make movement possible, not a treatment in itself. Here is how to pick and how to sequence it.

Heat before, movement after
For a stiff, chronically tight muscle, ten to fifteen minutes of moist heat before release and stretching makes the tissue easier to work with and the session more tolerable. Follow it immediately with movement.
Heat alone rarely changes anything for more than an hour, which is why it belongs at the start of a routine rather than as the routine.
Where cold fits
Cold is useful for an acutely irritable, recently overloaded area, and after a session that provoked more soreness than intended. Ten minutes, skin protected, is enough.
The classic spray-and-stretch technique uses a rapid cooling spray over the skin while the muscle is taken through a slow passive stretch — the cooling reduces the reflex resistance long enough to gain range.
A simple decision rule
Tight and old: heat first, then release and move. Angry and recent: cold, gentle range, and postpone deep pressure. Unsure: pick whichever makes the next movement easier and use that.
Neither replaces working out why the muscle keeps being overloaded — that is what the perpetuating-factors checklist is for.
