perked up
Grew more alert
Perked up means became more lively, alert, or cheerful after a period of low energy or spirits.
A tired person perks up after coffee; a sad dog perks up when its owner returns.
The phrase suggests a visible shift—ears literally perk up, posture straightens, attention sharpens: She perked up when she heard her name mentioned.
