Exercise: The Controversial Approach
Exercise is a controversial topic when it comes to ME/CFS. You're probably asking, "How can exercise help when it's the cause of PEM in the first place?"
Most experts agree people with ME/CFS need to get some exercise.11 Muscle atrophy and inactivity make you even less able to handle exertion. They also increase other symptoms (pain, stiffness) and your risk of other illnesses.
However, you can't handle therapeutic exercise like other people.12 You must know your limits and stick to them strictly.
Some people with ME/CFS turn to physical therapy, but with mixed results. It's important your therapist is familiar with your inherent restrictions so they don't push you too far and make you worse.13
A segment of the medical community advocates a treatment called Graduated Exercise Therapy (GET) as a first-line treatment for ME/CFS. They point to research suggesting that it's beneficial.
On the other side, though, is research suggesting that GET is actually harmful to people with ME/CFS.14
