If you’ve tweaked your back, strained a calf, or picked up a niggling shoulder ache, you’ve probably been told to “just rest it.” It’s well-meaning advice, and for the first day or two after an injury, it isn’t wrong. But for most of the aches, strains and sports injuries we see here at Next Level Physiotherapy in Cork, complete rest for weeks on end tends to do more harm than good.
Here’s why, and what we would recommend instead.
Why “just rest” became common advice
The idea that rest heals injuries isn’t baseless. Decades ago, the standard advice for almost any soft tissue injury was RICE: Rest, Ice, Compression, Elevation. It made sense at the time: reduce movement, reduce pain, let the body do its thing.
The trouble is, research into tissue healing has moved on a lot since then, and “rest” got stretched well beyond what it was ever meant to cover. A few days of protecting an injury became weeks of avoiding activity altogether, and that’s where problems start.
Why rest actually is important
To be clear, rest still has a place. In the first 24–72 hours after an acute injury (a sprained ankle, a pulled muscle, a fresh strain), some protection and reduced load can help manage pain and swelling. This is sometimes referred to as the POLICE principle: Protection, Optimal Loading, Ice, Compression, Elevation, which replaced RICE for good reason: it builds gentle movement back in early, rather than removing it altogether.
So short-term, modified rest: yes. Weeks of avoiding movement: generally not.
Why too much rest can slow recovery
Once you’re past the acute stage, prolonged rest can actually work against you. Muscles, tendons and joints are designed to be loaded. When you stop using them:
- Muscles lose strength and size: deconditioning can begin within days of inactivity
- Tendons lose tolerance to load: making them more sensitive when you do return to activity
- Joints can stiffen: reducing your range of movement
- Pain sensitivity can increase: meaning normal movement starts to feel more uncomfortable than it should
- Confidence in the injured area drops: which often leads to people moving more cautiously long after they’re physically ready to move normally
None of this means you’re making the injury worse by resting, but it does mean recovery stalls, and getting back to normal activity often takes longer than it needs to.
What happens inside the body when tissues stop being loaded
Tissue healing isn’t a passive process, it responds to load. When you gradually and appropriately load a healing muscle, tendon or ligament, you’re giving it a signal to rebuild stronger and more resilient muscles. Collagen fibres realign along the lines of stress, blood flow improves, and strength returns.
The importance of gradual movement
The key word here is gradual. We’re not suggesting you push through an injury or ignore pain. What we’re talking about is appropriate, progressive loading, starting with gentle movement, building up strength and range, and gradually reintroducing the activities you want to get back to.
This is exactly what a tailored rehabilitation programme is designed to do: match the right amount of movement to where your tissue is in its healing process and build from there.
Why pain doesn’t always equal damage
One of the biggest hurdles in recovery is the belief that any pain during movement means you’re causing more damage. In reality, some discomfort during rehab exercises is normal and expected, especially with tendon and muscle injuries.
A useful general guide we use with patients: mild discomfort means keeping pain under a 4/10 (0 being no pain and 10 unbearable), when exercising, is considered the safe zone. A pain that settles down afterwards and isn’t worse the next day is usually fine. Sharp, worsening pain, or pain that lingers and gets worse over the following days, is a sign to scale back and get it checked.
How physiotherapists guide safe recovery
This is where expert physiotherapy guidance can make all the difference. Recovery isn’t one-size-fits-all, the right amount of rest, and the right progression of movement, depends on the specific injury, how irritable it is, your goals, and your starting point.
At Next Level Physiotherapy, a thorough assessment lets us build a plan that’s specific to you: identifying what’s driving your pain, how much load your tissue can currently tolerate, and a clear, staged pathway back to full activity, whether that’s running, playing GAA, getting back to the gym, or simply being able to sit and stand without discomfort.
When you should stop exercising and seek assessment
This isn’t a blanket “keep pushing through everything” message. There are times when it’s important to stop and get assessed rather than continue on your own:
- Sharp, sudden, or severe pain
- Significant swelling, bruising, or visible deformity
- Pain that’s getting worse day by day despite rest and activity modification
- Instability, giving way, or an inability to bear weight
- Pain that hasn’t improved after a couple of weeks of trying to manage it yourself
- Any injury you’re unsure about
Signs it’s time to book a physiotherapy appointment
If you’re dealing with any of the following, it’s worth getting a proper assessment rather than guessing:
- An injury that’s stopping you doing the things you enjoy
- Pain that keeps coming back
- Uncertainty about whether it’s safe to keep exercising
- An injury that hasn’t improved despite rest
- Wanting a clear, structured plan to get back to sport, training, or everyday activity
If you’re dealing with an injury and you’re not sure how much rest is enough, or how to safely start moving again, we’re happy to help you figure out the right approach. Book an assessment with us and we’ll build a plan around your injury and your goals.
FAQs on injury recovery
Only for a short period immediately after an acute injury (roughly 24–72 hours). Beyond that, most injuries benefit from gradual, appropriate movement rather than complete rest.
In most cases, yes. Walking is low-impact and can help maintain circulation, mobility and general conditioning while you recover, as long as it doesn’t significantly worsen your pain.
Yes. Appropriate, progressive loading is a key part of tissue healing, particularly for tendon and muscle injuries, and is generally more effective than rest alone.
If pain is severe, worsening, not improving after a couple of weeks, or if you’re unsure how to safely return to activity, it’s worth booking an assessment.
No. Mild to moderate discomfort during rehab exercises that settles afterward is common and often part of the recovery process. Sharp or increasing pain is different and worth getting checked.
