Yes, there's still a lot not known about the actual cause of psychic abilities, and although I've never known any side effects being caused by the Limiters, we do take into account that it does suppress the power, so I'd recommend at least having some time without wearing it now and then, possibly when you're at home or in a place where, if the ability was to act up, it wouldn't do any harm.

For Tomoko here, her powers showed signs of developing when she was quite young, but we didn't get her a limiter until the ability started to manifest more strongly a few years ago, just so we didn't risk anything like accidentally stunting her abilities as they were developing.
