Likewise, what happens when we arechronically sleep deprivedwill that impact our memory on a more long-term basis?
While we sleep, we cycle through different stages of sleep.
Each of these primary memory stagesSWS and REMplay slightly different roles.

In a nutshell, SWS is for consolidating memories that include facts or events, Dr. Hafeez says.
But REM sleep is more about procedural memory consolidation.
Sleep also helps protect memories by stabilizing and safeguarding them over time, Dr. Hafeez explains.
This is due to something called synaptic plasticity.
Sufficient sleep allows our brains to process and store information effectively, facilitating optimal cognitive development, he describes.
Even though the millions of neurons in the brain slow down during sleep, theyre still performing important work.
Dr. John adds that memory processing in particular is one of the most importantbenefits of a good nights sleep.
Can Better Sleep Improve Your Memory?
Better sleepplays a significant role in improving memory, Dr. Hafeez explains.
Dr. John suggests jogging your memory back to when you were in school.
Imagine listening to a lecture during the day.
The brains glymphatic systems function is akin to clearing the cobwebs, or cellular trash, he describes.
Over time, this can contribute to long-term cognitive issues and an increased risk of dementia.
But its not all gloom and doom.
Consistently getting less than this amount can impair cognitive function, he says.
But its not just quantityits also quality of sleep.
Quality is as important as quantity, says Dr. Allen.
Left untreated, sleep disturbances can affect memory and even lead to larger health consequences.
You should speak to your healthcare provider if you are concerned about a possible sleep disorder.
Sleep plays an important role in memory.
The problem is that it can be super hard to get the sleep we need.
Consider connecting with a healthcare provider if sleep continues to feel out of reach.
