While we sleep, a process known as consolidation takes our short-term memories and transfers them into long-term memories. All of the short-term memories are made up of the information we gather during the day, information which needs to be processed. Sleep is vital in that it helps us with this, it enables us to understand the information and strengthen memories.

No sleep, no memories.
