exit during long sleep

Whats the easiest way to exit this While loop while its still sleeping? is there some kind of function that can detect if a value is true while sleeping? or do i set up a small sleep in a loop and check to exit if not sleep some more? if so how would i do that?

        while (_execute.load(std::memory_order_acquire)) 
        {
            //do stuff

            //How to exit druing this long sleep
            std::this_thread::sleep_for(std::chrono::minutes(_Delay));
        }
