Definition
Sedatives are drugs that depress activity in the central nervous system, producing calmness, drowsiness, reduced anxiety, or sleep. They slow reaction time, impair judgment, and degrade coordination, and are disqualifying for flight under FAA medical standards.
Plain English
Medications that calm you down or help you sleep by slowing the brain and nervous system. They make you slower to react and less sharp -- which is why pilots cannot fly while taking them.
Context Anchor
Seen in aeromedical discussions about drugs, fitness to fly, and medications that can make a pilot unsafe to operate an aircraft.
Derivation
From the Latin sedare, meaning 'to settle' or 'to calm.' The same root gives us 'sedate.' The word literally describes drugs that settle the body and mind down.
Why Pilots Care
Sedatives impair reaction time, judgment, and coordination, directly violating FAA rules against flying under their influence.
Intuition Check
Do not think of sedatives only as strong sleeping pills. In aviation, any drug that calms or slows the nervous system enough to affect alertness or judgment can be a safety problem.
Example Sentence 1
The pilot grounded himself for the trip after his doctor prescribed sedatives to help him sleep through a stressful week.
Example Sentence 2
