How Sleep Affects Your Memory

Making sure you get at least eight hours of productive sleep a night is also one of the surest ways to keep a sharp mind. No matter how much one learns in their waking hours, it is during slumber that our day’s events are processed and formed into something we can remember and focus on later. Without proper sleep, our short-term memories can’t be transferred into the brain’s long-term hard drive, and there is little hope of ever remembering anything.

In order for something to become a memory, three processes must occur.

ACQUISITION

First, there is the acquisition of memory. While we are awake we learn about or experience something new. This event is registered in our short-term memory and stays there until we go to sleep.

CONSOLIDATION

During sleep, the body recharges and the brain replays the events of the day for review, consolidating and transferring them to the back of the brain and into our long-term memory. This process allows them to stick with us as stable entities.

RECALL

Finally, upon waking up, we are able to enjoy recollection of these memories and can access them in the future.

Both acquisition and recall are functions that take place when you are awake. However, researchers believe sleep is required for consolidation of a memory, no matter the memory type. Without a good night’s sleep, the storage of these memories is compromised, which affects not only our ability to concentrate on forming new memories during the day, but also to remember those that we’ve already spent time storing.

And not only is your brain holding onto valuable memories, it’s also wiping out the inconsequential stuff.

Here are a few strategies to ensure a good night’s sleep that leads to a sharp memory:

Keep a routine

Keeping set times for waking, eating, exercising, and going to bed helps keep the body in check and allows it to make the most of the sleep cycle.

Have fun in the Sun

Our bodies are heavily regulated by sunlight. Spend time outdoors or near sunlight to help your body align with its circadian rhythm.

Talk to your doctor

Pharmaceuticals can interfere with sleep. Talk to your doctor to make sure that any medications you are taking are properly timed and will not affect your ability to fall asleep.

 

We encourage you to try some of these strategies, and be mindful of how your mind and body react.

Sweet dreams!
