A static (also known as a stationary or standing) electromagnetic wave is nothing more than a normal electromagnetic wave x2. To be as specific as possible without being technically wrong, it can be described as the end result of an electromagnetic wave reflecting off "something" thus retracing it's steps (hence the x2).
In the off chance another "something" causes more reflecting, the situation can become a little hairy. Which is one way to describe what's perceived should a person be located in the middle of several such waves.
Electromagnetic waves - being quick and related to the speed of light as Danish astronomer Ole Roemer measured - can reflect around quite often in a short amount of time. Should a set of "somethings" reflect them multiple times, a person can actually notice their existence while passing through. This also introduces interference which breaks or collapses the static, stationary, or standing part of it all.
Static, stationary, or standing waves are stated to have no net transfer of energy - and there's no reason to disagree with that. Leaving the subject behind on that one fact might give someone the impression they're harmless. If the x2 nature (or another x of greater number but diminishing return) is considered, there's more potential harm to go around.
Healthline.com has a thorough article on what that may entail. It's not their fault that it's excerpted by Google as:
"Exposure to large levels of high-frequency EMFs is known to damage human DNA and cells. But it's very unlikely that you'll be exposed to levels high enough to endanger your health in your daily life."
