the importance of memories

Sleep is a chance for our bodies to repair, recover and reflect on the day just gone, in order to prepare you for what tomorrow brings

Recent events are stored as memories and often contextualised within the bigger picture, allowing you to wake in the morning with a new outlook on a previous issue. With memories being key to defining who we are, we should be doing the utmost to care, protect and preserve them.


One of the best ways to preserve old memories and prepare your brain for making new ones is to ensure that you have a great night’s sleep. Matt Walker, author and sleep expert, recently discussed this during a TED talk in which he neatly explained the important relationship between sleep and memory consolidation:


“We need sleep after learning, to essentially hit the save button on those new memories. Recently we discovered that you also need sleep before learning, to actually prepare your brain, almost like a dry sponge ready to initially soak up new information, and without sleep,  memory circuits of the brain essentially become waterlogged as it were and you can’t absorb new memories.”


So the amount of sleep that we get directly corresponds with the quality of memory retention. Preparing our bodies properly before we sleep gives our minds the best chance to absorb those new memories. Matt identifies two essential ways we can prepare our bodies in this way to ensure optimum memory retention.


The first is regularity, making sure we go to bed and wake up at the same time every day, no matter if it’s a weekday or a weekend. This sets our circadian rhythm in perfect timing, and will result in you staying awake in the day and floating to sleep at night. As Matt suggests “Regularity is king. It will anchor your sleep and improve the quantity and quality of that sleep.”


The second is temperature, ensuring that your sleeping environment is in a state of perfect balance. “Your body needs to drop its core temperature by about 2-3 degrees fahrenheit to initiate sleep…and it’s why you’ll always find it easier to fall asleep in a room that’s too cold than too hot”


Here at nanu we and Matt Walker are on the same page. Sleep is a fundamental part of the recovery process, and ensuring you have the right pillow that supports your head, neck and back is an essential element of this. Our premium pillows can be tailored to the specifics of the way you sleep, giving you the ability to have the best sleep possible. By following our online pillow builder and selecting your weight, height, sleeping position and preferred density of your pillow, the experts at nanu can craft your perfect pillow.


It is crucial throughout life, especially in the early years of development and the later stages of memory erosion, that we maintain our memories through the proper regulation of sleep. As Matt rightly observes  “Sleep, unfortunately, is not an optional lifestyle luxury. Sleep is a nonnegotiable biological necessity. It is your life support system.”
