The ‘Massage Flu’ Myth, Explained

You Should Know: Massages are supposed to feel great, but sometimes people feel pretty terrible afterward — even like they’re coming down with a cold. It’s a phenomenon known as “massage flu.” Some claim it’s caused by the body “releasing toxins,” while others point the finger at lymphatic fluid movement or post-rubdown inflammation. So, why does this actually happen? 

Going Deeper: “Massage flu” is not an official medical term or diagnosis, nor are people actually sick afterward. Even so, that doesn’t mean they don’t sometimes feel a little off after getting one. Experts say that unwell feeling is most likely due to the body responding to changes to the circulatory, lymphatic, and nervous systems. 

Takeaway: Following a massage, some people may get a little headache after, or feel more emotional than normal, a little sore, or deeply relaxed. Others might feel like they’re getting a cold or the flu. Dehydration can contribute to this. Drinking lots of water after a massage is super-important because of increased circulation and lymphatic drainage. 

Bottom Line: Deep-tissue massages tend to trigger flu-like symptoms more than relaxing types, like Swedish massage. Be sure to book massages only with licensed, experienced practitioners.
