overactive
Excessively busy, restless
Overactive means functioning more than normal or necessary.
An overactive thyroid produces excess hormones.
An overactive imagination conjures worries or fantasies beyond what circumstances warrant.
An overactive bladder signals urgency too frequently.
The word often carries mild criticism—suggesting something needs calming down rather than ramping up.
