Many massage therapists believe1 that massage releases toxins into the bloodstream, which can then be washed away by drinking water after you get off the table. Exactly which toxins and how they are “flushed” by massage or washed away by water is completely unclear to anyone. Many therapists know it’s all rather vague but apply the precautionary principle: drinking water certainly won’t hurt, right? No, probably not (although unnecessary worries about dehydration and over-hydrating are bigger problems than most people realize2).
It’s polite and pleasant to offer post-massage water, but there’s no biological, detoxifying need for it. It’s about on par with a recommendation to “think positively” or “go for a short walk to get your blood moving” — fine things, but tepid medical advice.
This article is detailed. For a much faster tour of the topic, just watch this fun video from Laura Allen, a massage therapist in Rutherfordton, North Carolina. I get a big kick out of her folksy 3-minute debunking of this classic massage myth. Her no-nonsense Southern twang and well-chosen words are perfect for this job!
How many massage therapists are still out there telling their clients that massage gets rid of toxins in the body? On any given day on Facebook, I see about half a dozen people making that claim … Would you maaahnd sharing with us exactly how that happens?
Laura Allen, Massage Therapist
Does massage release toxins? Which toxins are these, exactly?
There are real toxins and some legitimate “detoxification” treatments, but casual and careless use of these terms is almost always a red flag,3 and a strong theme in all the bizarre and medically illiterate “shit massage therapists say.”4 It is accompanied by a more or less perfect ignorance of which toxins. Are we talking about lead poisoning here? Pesticides? What chemicals? Dihydrogen monoxide?5 Magnesium sulfate?6 What?
The toxin-talkers do not know. Or, worse, they think they know — but give examples that are mythical,7 and/or absurdly extreme.8
The body deals with undesirable molecules in many ways. It excretes some and recycles others; some are trapped in relatively safe places (sequestering); and quite a few can’t be safely handled at all (metals like lead). Most alleged “detox” treatments are focused on supposedly stimulating an excretion pathway, like sweating in a sauna — but sweating is mainly secretory, not excretory (sweating is about cooling, not taking out the trash).9 There are very few truly “detoxifying” treatments that help the body eliminate or disarm molecules the body cannot process on its own. For instance, a stomach pump for someone with alcohol poisoning is literally “detoxifying.” So is an antivenom, or chelation therapy for heavy metals.10
When massage therapists talk (or think) about detoxifying, they need to be much more specific: what molecule, how it normally works, and how massage or water intake supposedly improves the speed or effectiveness of normal biological waste processing (recycling, sequestering, or elimination). So what are some of the specific possibilities?
The real toxins
A poison is literally any harmful substance, and even something safe in typical doses becomes a poison in overdose (so you can be poisoned by either lots of water or a minuscule amount of lead). Toxins are technically poisons produced by living things, like venom or metabolic wastes, but informally the word is synonymous with poison.
Of course there’s a staggering variety of poisons/toxins, but pollutants are probably what most people hope to purge. The best specific candidates would be the persistent organic pollutants like pesticides, flame retardants, and polychlorinated biphenyls (PCBs, now banned, but formerly ubiquitous in many plastics). Lead is also an alarmingly common environmental poison (and much in the news lately). All of these are indeed found in our environment and our bodies, where they mostly get trapped in fat and otherwise sequestered.
The idea that massage liberates any of these substances is extremely implausible, and is probably not what is meant by the average massage therapist. Any massage therapist who thinks they are squishing environmental pollutants out of your cells and into an excretory pathway (like urination) is really far out in left field. There is a more reasonable idea …
When pressed to be specific about what toxins massage is flushing, some therapists will guess “metabolic wastes,” the chemical products of cellular activity. The rest of the article will stick to the idea that the only “toxins” relevant to massage are waste metabolites.
But it’s a large category that isn’t much of an answer. Cellular chemistry produces a lot of molecules, with many fates. Technically they are toxins because they are biologically produced, and would be harmful in abnormal concentrations. But these are the normal products of biology, and so most of them are either safely excreted, or actually re-used and re-cycled, not “waste products” at all …
As in the rest of nature, not much in cellular chemistry is wasted. Most metabolic “wastes” actually have utility throughout a cascade of functional interactions. You literally don’t want to “flush” these. You want them to go through their normal chemical lifecycle, processed and re-processed. Trying to flush them out would be sort of like trying to improve a car engine by getting rid of the exhaust before it hits the turbocharger.11 Such metabolic by-products are not just nasty chemicals pooped out by cells that just hang around, stuck in tissue, waiting for your friendly neighbourhood massage therapist to come along and flush them away.
Lactic acid is the ultimate example.
It’s clear that we still don’t have a fix on exactly which toxins therapists might think they are flushing. Let’s work with an example of a rock-star-popular waste metabolite: lactic acid, or lactate.
Lactic acid is the poster boy for the “waste” metabolites, probably the only one that’s a household name, and most massage therapists still assume that lactic acid can be flushed by massage. This is not a difficult thing to test, and it has been tested, and some results were a bit shocking: not only does massage definitely not “reduce” lactic acid,12 perhaps massage even “impairs lactic acid and hydrogen ion removal from muscle.”13
This is not really surprising. If people needed massage to help them “clear” lactic acid, sprinters would drop like flies without emergency massage after every race. The effect must be minor or non-existent.
In any case, it’s worth emphasizing that lactic acid is not the cause of muscle pain at any time. Recent (2008-2010) research has shown that muscle fatigue and the “burn” that you feel as you exercise intensely is probably caused by calcium physiology, not an accumulation of lactic acid.14 In particular, lactic acid does not cause soreness the day after exercise — it’s long gone by then.
And there’s more: lactic acid is actually a useful molecule with a productive metabolic fate, not a dead-end waste product. Lactate as a “bad” molecule is one of the most persistent silly myths in all of exercise science.15
So presenting lactic acid as some kind of metabolic bogeyman that massage can get rid of is wrong, wrong, wrong on many levels. And any other metabolic waste is even less likely to fit the bill. So this is another nail in the coffin of the biologically illiterate notion that massage somehow “detoxifies.”
But it gets worse. Now it’s time for a plot twist.
Oh, irony: poisoned by massage!
Massage is toxic?
Technically. But so is good scotch. And hard exercise.
Not only is massage not a detoxification treatment in any sense, it is actually the opposite: a toxifying treatment. A little bit. Sometimes.
Post-massage soreness and malaise (PMSM) is a common phenomenon after any strong massage. It is probably caused by mild rhabdomyolysis (“rhabdo”), a form of poisoning. True rhabdo is a medical emergency in which the kidneys are poisoned by myoglobin from muscle crush injuries. Myglobin is a true toxin, a biologically produced poison, which we can handle in small doses but start to struggle with in larger doses.
Many physical and metabolic stresses cause milder rhabdo-like states — even just intense exercise, and probably massage as well. This is substantiated by a case study of acute rhabdomyolysis caused by intense massage,16 by many well-documented cases of exertional or “white collar” rhabdo, and by the strong similarity between PMSM and ordinary exercise soreness (delayed-onset muscle soreness).
A rhabdo cocktail of waste metabolites and by-products of tissue damage is probably why we feel a bit cruddy after biological stresses and traumas — even massage, sometimes. It’s not that big a deal. Massage is still worthwhile. But it is, technically, a little bit toxifying — not de-toxifying.
Nor can massage get rid of any rhabdo it causes. You can’t “flush” the rhabdo cocktail away with massage, or drinking a little extra water — or any amount of water. PMSM is just an unavoidable mild side effect of strong massage, just like soreness after intense exercise. I have a detailed article just about rhabdo, which explains exactly why it can’t be “flushed.” The rest of this article explains the futility of flushing in more general terms.
And how is water supposed to help anyway?
Even if there are some problematic waste metabolites in your tissues, and even if they can be mostly liberated into the bloodstream … why would drinking a couple extra glasses of water help get rid of them?
There’s a prevalent and vague belief that drinking water somehow “rinses” your blood vessels or cells … or something. But your circulatory system is not a simple system of tubes that you can flush out by imbibing extra water. This makes about as much sense as adding fuel to a car to make it go faster.
In fact, fluid balance is quite stable and somewhat independent of modest changes in water intake. Drink some extra, drink some less — your blood volume will stay almost exactly the same. Your body is an “ugly bag of mostly water,” but the total amount of water in circulation — in your blood and between your cells — remains nice and steady. You only need so much of the stuff. Just like your respiratory system excels at maintaining constant levels of oxygen and blood acidity, your guts cleverly keep your insides just the right amount of wet. Drinking more water than you need doesn’t add it to your bloodstream — you just piss away the extra!
The liver and the kidneys are the primary detoxifying organs: this is where most junky molecules are transformed, disarmed, and/or excreted. And they don’t require extra water to work any more than they need extra food to work. Their elaborate chemistry marches on unperturbed, whether you drink 4 glasses of water per day or 12. If you are significantly dehydrated, of course you would certainly start to have problems — but liver and kidney failure are not among the early consequences!
The many fates of metabolites
Carbon dioxide is a prevalent waste metabolite, and an easy one to understand: your cells produce it via combustion of fuels with oxygen, like a trillion17 teensy car engines. It may be found at high levels in myofascial trigger points (muscle knots), indicating that they are metabolically “revving.”18 To hammer home that this stuff really is a “toxin,” CO2 is also chemically equivalent to acidity: to be CO2-polluted is to be acidic!
But CO2 disposal just has nothing to do with water, nothing at all. Its fate is completely separate from fluid balance.
Carbon dioxide is processed at extreme speeds — quite “aggressively,” because we cannot tolerate much variation in acidity — primarily by a chemical pathway through the bloodstream and lungs: a pathway that does not much involve the kidneys, fluid balance, or fluid excretion. And the amount of CO2 involved in trigger point toxicity is a drop in an ocean of chemistry anyway. Even if massage squished a trigger point’s full cargo of CO2 into the bloodstream, that’s an infinitesimally small amount of CO2 compared to the total CO2 produced in a single second by all of the body’s cells. We produce and process vast quantities of CO2 constantly, and we do it effortlessly.
So much for that prominent toxin being flushed away by water!
And so it is with all the other “toxins” in a trigger point — problematic when concentrated in a patch, they are otherwise trivial and unaffected by water intake in any case. Even supposing that squishing a trigger point magically forces every molecule of every pain-causing metabolite into the bloodstream (not just into adjacent intercellular fluids, which is actually more likely), they still wouldn’t require further “flushing” by any means. Once in the bloodstream, they would be lost like motes in a sandstorm, joining billions of their metabolic siblings that are routinely produced — and processed — by all the cells of the body, and drinking water has no relevance to those processes.
What about “lymphatic drainage”? Isn’t that a clear example of detoxifying massage?
No. This comes up in most Facebook debates between massage therapists on this topic. It’s a red herring. Manual lymphatic drainage (MLD) is a fairly exotic and specialized manual technique for reducing swelling. Although it is performed with the hands and a natural fit for massage therapists to learn, it is not “massage” per se, and the effect is mostly absent from all other kinds of massage. It has a reputation for impressive, visible effects on swelling — which have been totally absent from some well-controlled tests,20 or (at best) quite a bit less impressive than its reputation would suggest.21
In principle, MLD supposedly stimulates/exaggerates the normal action of the lymphatic system, the primary function of which is not waste disposal but the removal of excess tissue fluids, and then the filtration of lymph through nodules of immune cells (lymph nodes). Lymph nodes are really not at all like the liver, which actually is a “waste processing plant.” The liver is the organ that processes junk in your blood. Lymph nodes are about catching invaders, foreign microbes, which makes them more like “security check points.” You can see from this difference that it’s not really correct to say that lymphatic drainage is about “waste removal,” even if there are some cellular waste products in lymph (and there probably are).
This is what happens when lymph doesn’t flow — swelling & lots of it. Not “toxicity.” It is easy to find many gruesome pictures of elphantiasis on the internet.
If lymph were critical for waste removal, then the major impact of failure of lymphatic drainage would be tissue pollution. But failures of lymphatic drainage — for instance, drainage can fail because of surgical damage to lymph vessels and nodes, and indeed that is why MLD exists as a therapy — do not result in tissue “toxicity” at all, but severe swelling (elephantiasis, in the most extreme cases). It’s super unpleasant, but it’s not an issue of toxicity.
So MLD isn’t really “massage” as we normally know it, and doesn’t “release toxins/wastes” in any case: that’s a gross misrepresentation of the physiology as I understand it, and cannot be used as an example of detoxifying massage … even if it weren’t for the evidence that it doesn’t work as advertised!
A classic case of oversimplification
The idea that drinking water after massage matters is a hopeless oversimplification, easily undermined by a cursory understanding of biochemistry. Metabolic wastes are already ubiquitous in tissue fluids, and they are constantly being produced and recycled. While massage has never been shown to have any significant effect on these processes — except to actually impair lactic acid removal! — it doesn’t even make logical sense that water would have anything to do with it. Anything the body can get rid of it is going to get rid of, with or without massage, and with or without any extra water.
The body is good at handling metabolic wastes, and even many exogenous poisons, without any special help. If it weren’t, we’d really be up the creek.
It’s certainly nice to offer patients some water after massage, to quench whatever thirst they may have. But it is not medically important for any specific biological reason, and it perpetuates several minor myths we would be better off without. Massage doesn’t really “detoxify.” Water doesn’t detoxify. And lactic acid is a useful metabolite, not a waste product. Adequate hydration is easy and mild dehydration is not a health risk.

The major myths about massage therapy are:
- Massage increases circulation. Probably not… and definitely not as much as a little exercise.
- “Tightness” matters. The three most common words in massage therapy — “you’re really tight” — are pointless.
- Massage detoxifies. It’s actually the opposite, if anything.
- Massage patients need to drink extra water to “flush” the toxins liberated by massage.
- Massage treats soreness after exercise. Studies have shown only slight effects.
- Massage reduces inflammation. An extremely popular belief based mainly on a single seriously flawed study.
- Fascia matters. The biggest fad in the history of the industry.
- The psoas muscle is a big deal. The most overhyped single muscle.
- Massage stimulates endorphins (natural opioid) and reduces cortisol (stress hormone). They do not.
- “Trigger points” are evidence-based. Actually, the science is seriously half-baked.
- Massage therapists have spooky palpation skills. No, it’s just ordinary expertise… and misleading.
The complete list of dubious ideas in massage therapy is much larger. See my general massage science article. Or you can listen to me talk about it for an hour (interview).

Appendix: What do massage therapists really believe about detoxification?
A common criticism of this article is that few massage therapists actually believe or say anything about detoxification at all — that it’s a myth that massage therapists believe that massage detoxifies. A myth? It’s reasonable counter-skepticism, but just speculation and contrary to my extensive experience.
I have an unusually good sense of what “many massage therapists believe” because they tell me, constantly, for many years now, responding to my widely read website. My email inbox is more or less constantly filled with examples. Here’s one that just happens to be in there as I write this, from a discontented massage therapist writing about her clinic:
My boss has an infrared sauna and she wants us all (her staff) to try to get our clients to have regular saunas because they are good for ‘detoxing the body’. She always uses the mercury example of how we must rid our bodies of this insidious substance, citing that most of us have amalgam fillings in our teeth.
I have also witnessed countless Facebook arguments on this topic — often triggered by this article — and there is often a militant “detox contingent” that truly, madly, deeply believes detox dogma. For example, here is the first comment on a Facebook share of this article:
massage stimulates circulation, mechanically and metabolically, which is an enormous factor in “toxin” processing.
But massage does not “stimulate circulation” to any significant degree (certainly much less than exercise).22 If not a militant “detox contingent,” even more inevitable is the innocent question (thoroughly answered above):
Doesn’t it help to flush lactic acid?
Sometimes I have heard massage therapists argue that it’s only a minority of bad apples and poorly-trained therapists who make detox claims. However, I was trained in British Columbia when 3000-hour training was standard — by far the most rigorous massage therapy training program in the world at that time, closer to physical therapy programs than most other training for MTs. And that is where I first encountered widespread detox claims and beliefs! So it’s clearly not a belief that is limited to poorly trained therapists.
Another clue that detoxification claims are not so rare or mild is that it tends to come up, with depressing frequency as an excuse for adverse effects. Unpleasant symptoms in the aftermath of massage, even serious ones, are often attributed to a “healing crisis” brought on by the detoxifying effects of massage. I have heard such anecdotes (complaints) countless times over the years from massage therapy consumers; my own clients told me about them many times, and many more readers. For a particularly chilling example, see What Happened To My Barber?

- Do they really? I substantiate this in an appendix to the article, What do massage therapists really believe about detoxification?
- Technically, it can hurt … and even kill. Excessive concern about dehydration leads to excessive hydration. And there is such a thing as “water toxicity,” and there have even been some deaths from drinking too much water, prescribed by alternative health care professionals who believe that chronic dehydration is the cause of many ills. That is not true. See Water Fever and the Fear of Chronic Dehydration.
- The idea of “toxins” is usually used as a tactic to scare people into buying de-toxifying snake oil of one sort or another. It’s not that there’s no such thing as a toxin — obviously there are toxic substances in the environment. The problem is with the kind of people who toss the idea around, the reasons they do it (profit), and their consistent and total failures to ever be biologically specific about what they mean. It is so vague that it’s literally meaningless, except as a marketing message. Indeed, “detoxification” may be the single most common marketing buzzword in alternative health care.

- Another joke! Magnesium sulfate is Epsom salt — often touted as a detoxifying agent, but this is chemically illiterate and biologically absurd. The irony and the joke is that Epsom salt is actually mildly toxic if you eat it or inject it. But bathing in it? Epsom salt in your bath makes bath water feel “silkier,” but that’s probably all: it’s unlikely to be biologically relevant to aches and pains, and it may not even make it through the skin (osmosis is not even relevant, and it cannot “detox” anything).

One of the classic claims of massage therapy is that it “aids muscle recovery from exercise … by increasing muscle blood flow to improve ‘lactic acid’ removal.” But this 2009 evidence shows that just the opposite may be the case, in at least some circumstances. It was a straightforward experiment: the researchers subjected twelve people to intense hand-gripping exercises and then measured their blood acidity with and without basic sports massage. Their measurements showed that massage significantly “impairs lactic acid and hydrogen ion removal from muscle following strenuous exercise by mechanically impeding blood flow.” Yes, you read that right: massage impairs.
That’s quite a surprising result that applies a firm push to the side of a classic sacred cow of massage lore. (Note that good corroborating evidence was published again in 2012: see Crane 2012. Or see Franklin 2014 for some contrary evidence.)

This research, funded in part by a giant corporation that sells bottled water, supposedly shows that surprising mild dehydration can make you a bit pissy and headachy.
The level of dehydration studied here is similar to what it takes to provoke thirst, and the effects on mood are presumably milder at the lower end of the range. So if the effect on mood is significant, we are probably also thirsty ... and if we’re not actually thirsty, the effect is probably pretty minor. That said, I might agree with the author’s conclusion that “increased emphasis on optimal hydration is warranted,” but I’m also guessing it’s not that big a deal, and I’m inclined to be rather cynical about it, because the conclusion is just so pitch-perfect for a study funded by a water bottling company.
Mood effects are not to be ignored, for sure, but they are also a lot less serious than the health effects that people tend to believe (mostly based on very successful fear-mongering by people selling ‘water cures’).
