Может и подходящий вариант, но хотелось бы узнать его актуальность в разговорной речи.

Или come back fresh TO. Например: "Rest, so you can come back fresh to do it again".

То что нужно! Спасибо, Jarek!

Elena, to "GET a new lease ON life" means to be close to death and to come away with a resolution to make something of oneself, to appreciate life after almost losing it.

Jarek, that's not very idiomatic, I'm afraid.

++Grumbler: you are fast becoming my favorite translator here.

Uly, in Br.E. they say "a new lease OF life" :) http://dictionary.cambridge.org/dictionary/english/a-new-lease-of-life
Russian dictionaries translate is as "воспрянуть духом", not necessarily after a period of illness. May be it's not correct...

A lease is a contract that gives you the right to use something or live somewhere for a certain length of time. When you come close to losing your life and then recover, you feel like somebody gave you a new contract and said "here, you can live another 50 years!" I can't believe the British say "lease of life," to me it sounds totally nonsensical. I learned something new.

Ok, thank you.
