Should I Use Ice or Heat for My Injury?
The Age-Old Question That Confuses Almost Everyone
You’ve just twisted your ankle, pulled a muscle, or woken up with a stiff neck. You hobble to the freezer, then pause. Wait – should it be ice or heat? You’ve heard conflicting advice from friends, family, and Dr. Google. One minute you’re reaching for the ice pack, the next you’re wondering if a hot shower might be better.
At Milton Physiotherapy, this is hands-down the most common question we get asked. The confusion is understandable – even healthcare advice has evolved over the years. Here’s the straight answer.
What's Really Going On?
The ice vs heat debate stems from understanding what’s actually happening in your injured tissue and what you’re trying to achieve.
Ice (cold therapy) works by:
- Reducing inflammation and swelling in the first 24-48 hours
- Numbing pain by slowing nerve conduction
- Constricting blood vessels to limit further tissue damage
- Reducing metabolic demand of injured cells
Heat (thermal therapy) works by:
- Increasing blood flow to promote healing
- Relaxing muscles and reducing stiffness
- Improving flexibility and range of motion
- Providing comfort through pain gate mechanisms
The general rule: Ice for acute injuries (first 24-48 hours), heat for chronic stiffness or before activity. But like most things in healthcare, it’s not always that simple.
What You Can Do at Home
Here’s your practical guide:
Use ICE when:
- You have a fresh injury (within 24-48 hours)
- There’s visible swelling or inflammation
- The area feels hot to touch
- You’ve got sharp, acute pain
- After intense exercise or activity
Use HEAT when:
- You’re dealing with chronic stiffness or tension
- Before exercise to warm up tight muscles
- For general aches and pains without swelling
- When you need muscle relaxation
- The injury is more than 48 hours old and swelling has settled
Application tips:
- Ice: 15-20 minutes at a time, with a thin towel barrier
- Heat: 15-20 minutes, never directly on skin
- Both: Wait at least 1 hour between applications
When It's Time to See a Physio
While ice and heat can provide temporary relief, they’re not long-term solutions. If your pain persists beyond a few days, is getting worse, or is significantly affecting your movement, it’s time for professional assessment.
Don’t rely on ice or heat as your only treatment—they’re tools to help manage symptoms while your body heals, not cures in themselves.
