The vital importance of sleep are being celebrated for World Sleep Day today.
The big day is on Friday and the annual event aims to show how sleep is essential to health but there are still huge issues with it across the world.
To put the topic in the spotlight, we found these nine sleep-related Echo photos in our archives.
Settle back for a trip into the past at Ryhope, the Stadium of Light and even a town centre car park.
