Experts Address 'Massage Flu' Phenomenon
Health professionals explain common post-massage fatigue and soreness, debunking myths about toxin release.
Some individuals report experiencing flu-like symptoms such as aches, fatigue, and headaches after receiving massages, a phenomenon often referred to online as "massage flu." While not a recognized medical diagnosis, health experts acknowledge that these symptoms can occur following massage therapy.
Physical therapist W. Zach Smith stated that while the concept of post-massage soreness has been discussed for a long time, the term "massage flu" has emerged more recently. He explained that prolonged or intense pressure on muscles during a massage can lead to soreness, similar to bruising. A mild inflammatory response in the body after a massage can also contribute to these feelings.
Chiropractor Drew Voelsch confirmed that he has heard patients describe similar reactions, sometimes calling it an "adjustment hangover." He noted that the symptoms, including soreness, fatigue, and mild headaches, are real but typically temporary, lasting about 24 to 48 hours. Headaches can sometimes be triggered by massage work around the neck, scalp, or jaw, areas associated with tension headaches.
Both experts, however, pushed back against the popular social media claim that massages release toxins from the body. Smith emphasized that this idea lacks scientific basis, and Voelsch added that the liver and kidneys are responsible for the body's detoxification processes.
To mitigate discomfort after a massage, Smith suggests requesting lighter pressure or shorter sessions, gradually increasing intensity over time. Voelsch recommends staying hydrated by drinking water, consuming a light meal beforehand, and engaging in gentle movement afterward.
While mild soreness is generally not a cause for concern, both professionals advised seeking medical attention for new, persistent pain. Voelsch specifically noted that symptoms lasting longer than approximately 72 hours, or those including fever, sharp or radiating pain, numbness, tingling, spreading swelling, or faintness, warrant a doctor's consultation.
