温度疗法 - 简单有效的疼痛缓解
Strategic use of heat and cold to manage pain and swelling. Heat relaxes tight muscles. Cold reduces acute inflammation. Knowing which to use when makes the difference.
Most people get it backwards - they ice a stiff muscle or heat a swollen joint, and wonder why it does not help. Heat and cold are powerful pain management tools, but only when used correctly.
Your physiotherapist knows exactly which one to apply at which stage of recovery.
Cold therapy (cryotherapy) constricts blood vessels, reducing swelling and inflammation in acute injuries. Apply within the first 48-72 hours after a sprain, strain, or flare-up.
Ice packs, cold compresses, or ice massage are applied for 15-20 minutes at a time, with a barrier between ice and skin to prevent ice burns.
Heat therapy increases blood flow to tight, stiff muscles, making them easier to stretch and mobilise. Hot packs, heat wraps, or warm towels are applied for 15-20 minutes before stretching or exercise.
Heat works best for chronic muscle tightness, stiff joints, and old injuries that ache in Melaka's air-conditioned offices.
Neither replaces exercise - they are preparation tools. Your physio uses heat to warm up tight tissue before mobilisation, or cold to reduce swelling after an intense treatment session.
Many Melaka clinics use both modalities strategically within a single session.
运作方式
The science
Heat and cold work by changing local tissue temperature, and the body responds very differently to each. **Heat** (40–45°C) opens blood vessels, softens collagen, reduces muscle guarding, and calms nerve firing - it prepares stiff, chronic tissue for movement.
**Cold** (10–15°C) constricts vessels, slows nerve conduction, and dampens acute inflammation - it is a short-term brake on a freshly injured system.
What you feel
Heat: a comforting, deep warmth that often makes people sleepy. Cold: sharp bite for the first 1–2 minutes, then numbness, then the famous "CBAN" sequence (Cold, Burning, Aching, Numb).
Both should be tolerable without pain; ice directly on skin or water hotter than a warm shower are both wrong.
Session protocol
Hot pack: 15–20 minutes, at least two layers of towel between pack and skin. Cold pack or ice bag: 10–15 minutes maximum, also with a towel barrier.
Contrast bathing (alternating hot and cold) is used for stubborn sub-acute swelling and some chronic pain conditions - 3 minutes hot, 1 minute cold, repeat for 15 minutes.
When to use which - the rule of thumb
Fresh injury with swelling (<72 hours): cold. Chronic stiffness that feels "gummed up" first thing in the morning: heat.
Muscle spasm without swelling: heat. Exercise-induced flare: cold after, not before.
Pre-stretching tight chronic tissue: heat. Nerve pain: usually heat, unless there is active inflammation.
Evidence base
Cold: strong evidence for acute soft-tissue injury, post-exercise muscle soreness, and post-surgical swelling management. Heat: strong for chronic low back pain, neck pain, and muscle-dominant stiffness; useful pre-exercise warm-up for older adults.
Both are cheap, safe when used correctly, and offer meaningful short-term benefit - especially as a self-management tool between physiotherapy sessions.
Who benefits most
Anyone looking for a drug-free, cheap, controllable way to modulate pain and stiffness. Patients taking NSAIDs for chronic pain can often reduce dosing by pairing ice or heat with exercise.
Elderly patients with osteoarthritis particularly benefit from daily 15-minute heat sessions before activity.
When it's not the right pick
Cold is avoided in Raynaud's, cryoglobulinaemia, cold urticaria, and over areas with impaired sensation or circulation. Heat is avoided over acute injury, active bleeding, malignancy, anaesthetised or impaired-sensation skin, and on the abdomen in pregnancy.
Neither should cause burns, blisters, or colour change that persists hours later.
How it fits into the bigger plan
Heat and cold are the cheapest, safest, most under-used tools in the physiotherapy toolkit. They are almost never the primary treatment, but pairing them correctly with exercise (heat before, cold after in most cases) often doubles how much useful rehab work you can tolerate.
At PhysioMelaka we teach the timing as part of every home programme.

Ice for the first 48-72 hours after acute injury (sprain, strain, swelling). Heat for chronic tightness and stiffness.
Never ice a stiff muscle or heat a swollen joint. If unsure, your physio tells you exactly which to use.
Apply for 15-20 minutes at a time. For ice, always use a thin cloth barrier between the ice pack and your skin to prevent ice burns.
Wait at least 1 hour between applications. For heat, ensure the pack is warm but not burning - test on the inside of your wrist first.
Contrast therapy (alternating hot and cold) can be effective for chronic conditions and recovery. Typical protocol: 3 minutes heat, 1 minute cold, repeat 3-4 times.
This creates a pumping effect that flushes inflammation and brings fresh blood. Ask your physio if contrast therapy is appropriate for your condition.
Partly. Tiger Balm and Counterpain contain menthol and methyl salicylate - these create a warming sensation on the skin via nerve receptors without actually heating deep tissue.
They work as a counter-irritant and are genuinely useful for mild muscle aches. Voltaren (diclofenac) gel is not heat therapy at all - it is a topical NSAID that reduces inflammation.
For a true heat effect deep enough to loosen tight muscle before stretching, use a moist hot pack for 15-20 minutes. Topical rubs are fine adjuncts but not a replacement.
Stop heat immediately, remove the pack, and cool the area under running cool (not cold) water for 10 minutes. If the skin shows only redness that fades within an hour, you have a mild first-degree burn - aloe vera gel and avoiding further heat for 3-4 days is enough.
If the skin blisters, peels, or the redness persists beyond 24 hours, go to Klinik Kesihatan or Hospital Melaka A&E - burns can worsen over the next 48 hours and benefit from proper dressing. Always set a 20-minute timer before using any heat modality.
