breathe life into something
breathe (new) life into (someone or something)
1. Literally, to revive someone who is not breathing, as by mouth-to-mouth resuscitation The lifeguard was able to pull the drowning boy from the pool and breathe life into him, thank goodness.
2. By extension, to revitalize something that has become dull or stale. The new CEO's creative approach really breathed new life into that failing company.
