🔵 Ice Therapy (Cold Therapy)
✅ Best For:
- Acute injuries: sprains, strains, bruises, bumps, and inflammation.
- Post-surgical swelling.
- Sharp, sudden pain.
- Sports injuries or joint flare-ups (e.g., gout or tendinitis).
❄️ How It Works:
- Constricts blood vessels (vasoconstriction).
- Decreases blood flow to the injured area.
- Reduces inflammation, swelling, and tissue damage.
- Numbs pain by slowing nerve signals.
🧊 How to Apply Ice:
- Ice pack wrapped in a towel (never apply ice directly to skin).
- Gel cold packs, frozen peas, or cold water baths.
- Apply for 15–20 minutes at a time, every 1–2 hours as needed.
- Ideal within first 48–72 hours after an injury.
⚠️ Precautions:
- Avoid prolonged exposure—can cause frostbite or skin damage.
- Not ideal for people with poor circulation or nerve disorders.
- Don’t ice before physical activity (it tightens muscles).
🔴 Heat Therapy
✅ Best For:
- Chronic pain: arthritis, back pain, neck stiffness.
- Muscle tension or spasms.
- Joint stiffness or mobility issues.
- Delayed onset muscle soreness (DOMS) after exercise.
🔥 How It Works:
- Dilates blood vessels (vasodilation).
- Increases blood flow and oxygen to tissues.
- Helps muscles relax and reduces stiffness.
- Improves tissue elasticity and range of motion.
🌡️ How to Apply Heat:
- Heating pads (dry or moist).
- Warm towels or rice socks.
- Warm baths, showers, or hot tubs.
- Apply for 15–30 minutes, 2–3 times daily.
⚠️ Precautions:
- Avoid using heat on fresh injuries—it can increase swelling.
- Don’t sleep with a heating pad on.
- Not suitable for areas with numbness or open wounds.
- Avoid if you have vascular disease or diabetes without consulting a doctor.
🌀 Combo Therapy (Contrast Therapy)
Alternating ice and heat can sometimes help for:
- Chronic injuries with flare-ups.
- Stiff joints with intermittent swelling.
Example: 10 minutes heat → 10 minutes cold → repeat 2–3 times.
