Ice or Heat? Why Sports Science Moved On From RICE

Introduction:

You go over on your ankle stepping off a kerb, or landing badly in five-a-side. Within minutes it’s throbbing and starting to swell. Almost on autopilot, you hobble to the freezer for a bag of peas, prop your foot up on the sofa and resign yourself to a week of doing nothing.

For decades, that was the textbook response: RICE, or Rest, Ice, Compression, Elevation. But sports science has moved on. The doctor who coined RICE has since changed his mind about ice, and many physiotherapists now follow a newer approach that puts gentle movement and loading front and centre.

In this guide, we explain what changed and why, whether you should reach for ice or heat, and what sprained ankle recovery time really looks like when you treat it the modern way.

Where Did RICE Come From?

RICE was introduced in 1978 by American sports medicine doctor Gabe Mirkin. It was simple, memorable and quickly became the go-to advice for sprains, strains and bumps everywhere, from school PE lessons to professional sport.

Over time, the acronym grew. PRICE added Protection, and POLICE swapped Rest for “Optimal Loading”. But the ice and rest parts stayed at the heart of it for a long time.

Why the Thinking Changed

As research piled up, two parts of RICE came under scrutiny.

Ice

Ice is good at one thing: numbing pain in the short term. But there’s little good evidence that it speeds up healing. Inflammation, the swelling and warmth you feel after an injury, isn’t just a nuisance. It’s part of how the body starts the repair process. Some researchers have suggested that heavy icing may interfere with that early repair work.

Dr Mirkin himself revisited his advice. In 2015 he wrote that it now appeared that both ice and complete rest may delay healing, instead of helping.

Rest

A short period of protection helps in the first day or two. But long periods of complete rest lead to stiffness, muscle loss and weaker tissue. Healing tissues respond to gentle, gradually increasing load. That’s how they rebuild strength and get back to doing their job.

Meet PEACE & LOVE

In 2019, physiotherapists Blaise Dubois and Jean-François Esculier published an update in the British Journal of Sports Medicine called “Soft-tissue injuries simply need PEACE and LOVE”. It splits recovery into two phases.

PEACE: the first few days

• P – Protect. Unload or restrict movement for one to three days, easing off as soon as pain allows.
• E – Elevate. Raise the injured limb above the level of your heart to help fluid drain away.
• A – Avoid anti-inflammatories. The authors argue that routinely suppressing inflammation, with medicines or heavy icing, may affect long-term tissue healing.
• C – Compress. A bandage or taping can help limit swelling.
• E – Educate. Understanding your injury, and that active recovery beats passive treatment, makes a real difference.

LOVE: after the first few days

• L – Load. Let pain guide you back into normal movement and activity as soon as you can.
• O – Optimism. Confident, positive expectations are linked with better recovery.
• V – Vascularisation. Exercise without pain by doing cycling or swimming so that the blood circulation is increased at the tissues which are in recovery mode.
• E – Exercise. Restore strength, mobility and balance. For ankle sprains, exercise is one of the best ways to prevent the injury coming back.

Notice what’s missing? There’s no “I” for ice.

So… Ice or Heat?

Here’s the practical, balanced answer.

In the first two to three days

Avoid heat. The NHS advises avoiding heat, such as hot baths and heat packs, as well as alcohol and massage for the first couple of days after a sprain or strain, because they can increase swelling.

Ice is optional. The NHS guide to sprains and strains still includes ice as part of PRICE, and a wrapped cold pack for short periods can genuinely ease pain. If it helps you feel more comfortable and move more easily, it’s fine to use. What sports science questions is relying on heavy, repeated icing to speed healing. Never put ice directly on your skin.

After the first few days

Once the early swelling has settled, gentle warmth can help ease stiffness and make movement more comfortable. A warm shower before your exercises is a simple option.

The real priority

Whether you choose ice, heat or neither matters far less than what you do next: protect briefly, then start moving. That’s the biggest single change in how injuries are treated today.

Sprained Ankle Recovery Time: What to Expect

Ankle sprains are one of the most common injuries there are, so it’s worth knowing what a realistic sprained ankle recovery time looks like.

According to the NHS, most sprains and strains start to improve within about two weeks. However, you should avoid strenuous exercise such as running for up to eight weeks, as there’s a risk of further damage. Severe sprains can take months to get back to normal.

As a rough guide, physios often describe sprains like this:

• Mild sprain: some pain and swelling, but you can walk. Often feels much better within one to two weeks.
• Moderate sprain: more swelling, bruising and difficulty walking. Typically three to six weeks before you’re back to most activities.
• Severe sprain: a large ligament tear, significant swelling and instability. Can take several months, and may need specialist assessment.

Your sprained ankle recovery time also depends on what you’re going back to. Walking to the shops is very different from playing football or running a half marathon.

How to Shorten Your Sprained Ankle Recovery Time

The fastest recoveries usually follow the LOVE principles: gentle, progressive movement started early. Here’s a simple progression:

1. During the first three days: the injured ankle should be protected, elevated, compressed, and the toes and ankle have to be moved gently but within the limits of painlessness.
2. Days 3–7: start walking normally as pain allows. Draw the alphabet with your foot to keep the ankle moving.
3. Starting from week two: calf raises must be added to the rehabilitation routine, alongside resistance bands training and balance training (e.g. standing on one leg).
4. Weeks 3–6: progress to hopping, jogging, and side-to-side movements.
5. Return to sport: only when you can hop, sprint and change direction without pain or wobbling.

Balance training is the step most people skip, and the reason so many ankles get sprained again. Retraining the ankle’s control is one of the most effective ways to cut your sprained ankle recovery time next time round, or avoid a next time altogether.

Common Mistakes That Slow Recovery

• Resting for too long. A week on the sofa leaves the ankle stiff and weak. Gentle movement from day two or three is usually better.
• Icing for ages, several times a day. Short spells for pain relief are fine; marathon icing sessions won’t make it heal faster.
• Going back to sport because it “feels fine” walking. Running, jumping and twisting ask far more of the ligaments.
• Skipping balance exercises. This is the biggest reason ankles get sprained again.
• Ignoring a wobbly ankle. If it keeps giving way, get it assessed.

Avoiding these mistakes is one of the simplest ways to keep your sprained ankle recovery time as short as possible.

When to Get Help Urgently

Go to A&E or call 999 if: you heard a crack, your ankle or leg looks out of shape, it’s numb or tingling, or the skin is blue, grey or cold. Contact NHS 111 if: you can’t put any weight on it, the pain or swelling is severe or getting worse, or you have a high temperature.

It’s also worth seeing a physio if your ankle still feels weak, unstable or painful after a couple of weeks, or if you keep going over on the same ankle.

How a Physio Helps You Recover Faster

A physiotherapist can check how badly your ankle is sprained, rule out a fracture or more serious ligament injury, and build a step-by-step plan that matches your goals. That usually includes hands-on treatment, a progressive strength and balance programme, advice on how much to do and when, and a clear return-to-sport plan.

Frequently Asked Questions

How long does a sprained ankle take to heal?

Most sprains improve within about two weeks, but the NHS advises avoiding strenuous exercise such as running for up to eight weeks. Severe sprains can take months.

Is it better to ice or heat a sprained ankle?

Avoid heat for the first two to three days, as it can increase swelling. A wrapped ice pack can ease pain if you find it helpful. After a few days, gentle warmth can help with stiffness.

Is RICE still recommended?

The NHS still recommends PRICE for the first couple of days. Many sports physios now favour PEACE & LOVE, which keeps protection, elevation and compression but adds early movement and drops routine icing.

Should I walk on a sprained ankle?

After the first day or two, gentle walking within comfort usually helps recovery. If you can’t put any weight on it, get it checked.

Can I take ibuprofen for a sprained ankle?

Some experts suggest avoiding anti-inflammatories in the first few days, as inflammation is part of healing. Ask a pharmacist or GP what’s right for you, especially if you have other health conditions.

Give Your Injury Some PEACE & LOVE

Ice isn’t the villain, and rest isn’t useless. But the science is clear that early, gentle movement is what really drives recovery. Protect your injury for a day or two, then let pain guide you back into movement, and your sprained ankle recovery time is likely to be shorter and your ankle stronger for it.
