Heat & Cold Therapy
Heating pads, ice packs, and contrast-therapy gear. When heat helps, when cold helps, and which products hold their temperature long enough to matter.
The single most common failure in this category is duration. A gel pack that is properly cold for six minutes is a gel pack that does nothing for the fifteen or twenty a session is supposed to last, and the cheap ones go slack and lukewarm well before that. We do not time them ourselves. We go after the buyer reviews that name how long a pack stayed properly cold, and we give that number rather than repeating the packaging.
Heating pads fail differently. The problem is rarely the maximum temperature and usually the auto-off timer, set at 15 or 30 minutes by a manufacturer worried about liability, which is shorter than most people want and cannot be changed. Uneven wire spacing is the other one: a pad with a hot stripe and a cold patch is a pad you keep shifting.
On which to reach for, the short version is that cold suits something that just happened and is swollen, heat suits something stiff and long-standing, and there are cases where the answer is neither. The tool on this site walks through that in four questions.
Burns from both ends are more common than people expect, particularly with a heat pad fallen asleep on, or an ice pack put straight on bare skin. A layer of cloth and a timer solve most of it.
This is general information, not medical advice. Loss of sensation, diabetes, circulation problems and open wounds all change the rules, and those cases belong with a clinician.
