clearheaded
Thinking without fog
Clearheaded means thinking clearly, not confused or impaired.
A clearheaded person can assess situations rationally and make sound decisions: Despite the chaos, she remained clearheaded.
The term often implies freedom from influences that cloud judgment—alcohol, emotion, fatigue: I need to be clearheaded for tomorrow's meeting.
