Hardly any toxins. That is unless you're exposed to high levels of chemicals, such as chloride, arsenic, mercury, and lead, almost everyday in your work or living environment. But if you live in a typical neighborhood in a First World society, like most parts of the U.S., Canada, and Sweden, then your chances of being constantly exposed to deadly levels of “toxins” is likely to be very low. However, there is a common misconception among massage therapists that massage therapy can “get rid of toxins” or drinking more water help “flush toxins out,” but that isn't exactly how our body works. Also, it is not our responsibility or business to decide whether a client or patient needs to get “detoxed” or not. Unless you are a qualified toxicologist, this is outside of our scope of practice.

This morning, I saw two posts on Facebook that address a very prevalent myth that many massage therapists still believe. Alice Sanvito, a massage therapist in St. Louis, Missouri, quoted someone who made big claims that “lactic acid and cellular waists (yes, that's what was written) wring from the muscles and become accessible to the lymphatic system for easy detoxing after a massage with proper hydration. Without hydration after deep tissue massage results in toxins and acids staying in the muscles resulting it soreness and even headaches.”
Another asked, “How do we address the overwhelming ignorance of our field?” and used the lactic acid release debate as an example. In fact, this shouldn't even be a debate, no more than debating whether our planet is spherical or flat. It's somewhat entertaining to read the comments this early in the morning because they're not scripted like “The Walking Dead” or a Trevor Noah stand-up. That's why I don't watch TV or even own one.
I don't know where the idea that lactic acid is a toxin and can be squeegeed out of your muscles like cleaning your car's windshield come from. What I do know is that massage therapists — even myself occasionally — need to review and understand basic human physiology so that we don't tell our clients, patients, colleagues, and other healthcare professionals such outdated and unsupported beliefs.

Like eating pizza and drinking wine, running should also be done in moderation if we want to reduce your risk in developing hip and knee osteoarthritis. A recent systematic review and meta-analysis published in the Journal of Orthopaedic & Sports Physical Therapy found that recreational runners had a lower incidence of knee and hip osteoarthritis than competitive/elite runners and sedentary and non-running folks. “These results indicated that a more sedentary lifestyle or long exposure to high-volume and/or high-intensity running are both associated with hip and/or knee [osteoarthritis]. However, it was not possible to determine whether these associations are causative or confounded by other risk factors, such as previous injury,” the authors reported. (1)
