I believe the answer is:
refresh
This clue is a double definition.
'revive' is the first definition.
(I've seen this before)
'reinvigorate' is the second definition.
(I've seen this before)
(Other definitions for refresh that I've seen before include "Stimulate as by reminding, or top up drink" , "perk up!" , "Jog" , "Renew" , "Revive, cheer" .)
