The fastest way to help muscle soreness is to keep moving. Light activity, proper nutrition, and adequate sleep do more for recovery than most popular remedies, and some widely used strategies like stretching and icing have far less evidence behind them than you might expect.
Muscle soreness that peaks 24 to 72 hours after a workout is known as delayed onset muscle soreness, or DOMS. Understanding what actually causes it, and what the research says about each recovery method, helps you spend your time on what works.
What Actually Causes the Soreness
For years, the standard explanation was that tiny tears in muscle fibers trigger inflammation, which causes pain. That story is incomplete. Research published in the Journal of Physical Therapy Science found that DOMS occurred even in conditions where no measurable muscle damage was present. The soreness appears to be driven more by nerve sensitization than by structural damage alone. Two specific signaling pathways, one involving nerve growth factor and another involving a compound that increases pain sensitivity in nerve endings, ramp up after unaccustomed exercise and make the tissue around your muscles temporarily hypersensitive to pressure and movement.
This matters because it changes how you should think about recovery. You’re not waiting for torn fibers to knit back together so much as waiting for your nervous system to calm down and your body to adapt to the new demand you placed on it. That adaptation is the whole point of training. Soreness is a side effect of the process, not a sign that something went wrong.
Light Movement Beats Rest
The single most effective thing you can do for sore muscles is gentle, pain-free movement. A 20 to 30 minute walk, an easy bike ride, or a light swim increases blood flow to sore tissues without adding further stress. This approach, called active recovery, temporarily reduces pain and delivers oxygen and nutrients to muscles that need them.
A framework published in the British Journal of Sports Medicine reinforces this idea. Called PEACE and LOVE, it was designed for soft-tissue injuries but applies well to exercise-related soreness. The “L” stands for load: mechanical stress should be added early, and normal activities resumed as soon as symptoms allow. The “V” stands for vascularization, meaning pain-free aerobic exercise started within a few days boosts blood flow to the affected area and supports recovery. The key word is “pain-free.” If your soreness is so intense that walking changes your gait, scale the intensity down further or give it another day.
Cold Water Immersion
Ice baths remain popular, but the evidence is more nuanced than locker-room wisdom suggests. Cold water reduces blood flow to damaged tissues, which limits swelling and can provide real pain relief. Research temperatures typically range from 8 to 15°C (46 to 59°F), with an average of about 11°C (52°F). Immersion should last at least 10 minutes for fluid shifts between tissues and blood vessels to occur, with 11 to 15 minutes appearing to be the sweet spot.
Here’s the catch. The same BJSM framework that recommends early movement also questions whether ice is wise beyond short-term pain relief. Cold can disrupt the inflammatory process your body uses to repair tissue, potentially delaying the formation of new blood vessels and slowing the arrival of immune cells that clean up cellular debris. If your goal is to feel better for a game tomorrow, a cold plunge may help. If your goal is long-term adaptation and strength gains from training, letting inflammation run its course could be the smarter choice.
Stretching Does Almost Nothing for Soreness
This one surprises most people. A large Cochrane review, the gold standard for summarizing medical evidence, found that stretching before exercise reduced soreness by about half a point on a 100-point pain scale. Stretching after exercise reduced it by roughly one point. Even combining both pre- and post-exercise stretching only shaved off about four points. The reviewers concluded that stretching does not produce clinically important reductions in delayed-onset muscle soreness in healthy adults.
That doesn’t mean stretching is useless. It can improve flexibility and range of motion over time. But if you’re stretching specifically to prevent or reduce next-day soreness, the data says you’re unlikely to notice a difference.
Eat Enough Protein
Your muscles rebuild using the amino acids from dietary protein, and falling short slows the process. Sports nutrition experts generally recommend 1.6 to 2.2 grams of protein per kilogram of body weight per day to maximize muscle repair and growth. For a 70 kg (154 lb) person, that’s roughly 112 to 154 grams daily, spread across meals.
Spacing your protein intake throughout the day matters more than slamming a shake immediately after your workout. Three to four meals each containing 25 to 40 grams of protein gives your body a steady supply of building blocks. Chicken, fish, eggs, Greek yogurt, beans, and tofu all work. The source matters less than the total amount.
Compression Garments
Wearing snug sleeves, socks, or tights after a hard workout can modestly reduce perceived soreness and swelling. The pressure limits fluid buildup in the tissue and supports blood return to the heart. For general recovery, garments in the 15 to 20 mmHg range are sufficient. Higher pressure (20 to 30 mmHg) is sometimes used after particularly intense sessions or for people managing specific medical conditions.
Compression won’t dramatically speed healing, but it’s low-risk and easy to use. If you find it comfortable, there’s no downside to wearing compression gear for a few hours after training.
Think Twice Before Reaching for Anti-Inflammatories
Ibuprofen and similar anti-inflammatory drugs are a reflexive choice when muscles ache, but they may work against you. The PEACE and LOVE framework specifically advises avoiding anti-inflammatory modalities after soft-tissue stress because inflammation is a necessary part of repair. Suppressing it, especially at higher doses, can negatively affect long-term tissue healing. The various phases of the inflammatory response help recruit repair cells, clear debris, and lay down new tissue.
For mild to moderate soreness, this means tolerating some discomfort is actually productive. If pain is genuinely interfering with sleep or daily function, a short course at the lowest effective dose is reasonable, but routine use after every workout is counterproductive.
Sleep and Hydration
Most muscle repair happens during deep sleep, when your body releases its highest concentrations of growth hormone. Consistently getting seven to nine hours gives your tissues the time and hormonal environment they need to rebuild. Dehydration, even mild, can amplify the perception of soreness and slow nutrient delivery to muscles. Drinking enough water throughout the day, not just during your workout, supports every other recovery strategy on this list.
When Soreness Is Something More Serious
Normal DOMS peaks between one and three days after exercise and gradually fades over the next few days. If your pain is far more severe than you’d expect for the workout you did, persists beyond a week, or comes with dark tea- or cola-colored urine, those are warning signs of rhabdomyolysis, a condition where muscle breakdown floods the bloodstream with proteins that can damage the kidneys.
Rhabdomyolysis symptoms can mimic ordinary soreness, heat cramps, or dehydration, and they sometimes don’t appear until several days after the initial muscle stress. Feeling unusually weak or unable to complete tasks you could normally handle is another red flag. The only definitive test is a blood draw that measures a muscle protein called creatine kinase. If you notice dark urine or extreme, worsening pain after exercise, get it checked promptly.
