Understanding Sleep: How to Improve Your Memory

Understanding Sleep: How to Improve Your Memory

Memories are something that many of us fear losing: traditional family recipes or the first time you went out on a dateeverything has a sentimental value that deserves a place in your memory. Think of the times you’ve flicked through old photos and spent the next few minutes or hours running through all the past memories; it’s a great feeling.

Due to our hectic lifestyles and multitasking schedules we’ve inadvertently lost the ability to remember things, but there is a saviour and few acknowledge the power of it. Sleep, alongside food and water, is one of the most essential parts of your life. An essential tool in recovery from a day’s worth of gruelling tasks, sleep has a sensationally brilliant effect on your memory storage and recalling abilities. We spend a third of our lives sleeping—by the age of 60 you would have slept a total of 20 years, so it’s important that you’re using that time effectively right?

To use it effectively, you need to understand the powers and capabilities you can unleash, try it tonight and chances are you’ll wake up with a number of new memories stored.

So, let’s look at how to improve your memory with sleep:

Habitual Practice

In order to improve both cognitive and muscle memory, the general guideline is to practice, practice, and practice some more. We assume that if we spend 1 or more hours going through the motions then the process will be stored into our memory bank.

This is true to an extent: Let’s say that you’ve got an important business meeting coming up that will require you to pitch from memory. Most people will walk around running through the slides for hours on end hoping that they remember everything and miss nothing.

The problem will be that only certain key stats and figures will be stored; in order to remember everything you’ll need to sleep on it. This is when the power of REM sleep (see further down) takes over and begins to rehearse the motions during your sleep.

High Value

Research shows that the if a memory has a higher value placed onto it, such as money-related tasks, the more likely it is to be rehearsed and stored in our memory bank during sleep. So how can you improve your chances of storing the pitch to your memory? Sleep on it.

Stress Free Problem Solving

Stressful situations release hormones into your body – notably cortisol, which, when large amounts are released, not only causes cognitive damage but also impairs the hippocampus (located in the medial temporal lobe of the brain) and its ability to store and recall memories. Excess cortisol leaves the body in a constant physiological arousal, the stress will then begin to activate our fight-or-flight responses which during pro-longed periods of stress can begin to impair our cognitive abilities.

When we sleep we go into the “safe zone”, which then drastically lowers chemicals in our body associated with stress. Memories can now be effectively rehearsed during periods of REM sleep, which will have a far higher chance of being stored in the long-term memory bank.

REM Sleep (Rapid Eye Movement)

To fully maximise the benefits and effects of sleep and improving our memories, we need to ensure we go through all the stages of REM sleep. Generally REM sleep occupies 20-25% of an adults total sleep, which equates to 90-120 minutes. We generally go through REM four to five times during a sleep cycle, with it generally being shorter at the beginning of the night and longer towards the end.

Stages of REM Sleep:

  • Stage 1 is when we close our eyes—this stage lasts between 5 and 10 minutes, during which we can be easily awoken.
  • Stage 2 is when our body begins to produce positive and negative waves, with the heart rate slowing and body temperature dropping, preparing to go into deep sleep.
  • Stages 3 & 4 are the deep sleep stages, also known as slow-wave sleep.

Each of these stages has a responsibility for our process of learning and memory storage. Some are good for creating and remembering new habits, others are good for retaining new facts you’ve learned, whilst others are used for building the understanding of relationships with the new found facts.

Some stages of learning during sleep are most notably effective at the end of the cycle, so when you’re doing research on how to improve your memory, it’s vital to understand that a full night of uninterrupted sleep is essentially the reason why you’ll store something or throw it away.

7 Signs That You’re Way Too Busy (And Need to Change That)

7 Signs That You’re Way Too Busy (And Need to Change That)

“Busy” used to be a fair description of the typical schedule. More and more, though, “busy” simply doesn’t cut it.

“Busy” has been replaced with “too busy”, “far too busy”, or “absolutely buried.” It’s true that being productive often means being busy…but it’s only true up to a point.

As you likely know from personal experience, you can become so busy that you reach a tipping point…a point where your life tips over and falls apart because you can no longer withstand the weight of your commitments.

Once you’ve reached that point, it becomes fairly obvious that you’ve over-committed yourself.

The trick, though, is to recognize the signs of “too busy” before you reach that tipping point. A little self-assessment and some proactive schedule-thinning can prevent you from having that meltdown.

To help you in that self-assessment, here are 7 signs that you’re way too busy:

1. You Can’t Remember the Last Time You Took a Day Off

Occasional periods of rest are not unproductive, they are essential to productivity. Extended periods of non-stop activity result in fatigue, and fatigue results in lower-quality output. As Sydney J. Harris once said,

“The time to relax is when you don’t have time for it.”

2. Those Closest to You Have Stopped Asking for Your Time

Why? They simply know that you have no time to give them. Your loved ones will be persistent for a long time, but once you reach the point where they’ve stopped asking, you’ve reached a dangerous level of busy.

3. Activities like Eating Are Always Done in Tandem with Other Tasks

If you constantly find yourself using meal times, car rides, etc. as times to catch up on emails, phone calls, or calendar readjustments, it’s time to lighten the load.

It’s one thing to use your time efficiently. It’s a whole different ballgame, though, when you have so little time that you can’t even focus on feeding yourself.

4. You’re Consistently More Tired When You Get up in the Morning Than You Are When You Go to Bed

One of the surest signs of an overloaded schedule is morning fatigue. This is a good indication that you’ve not rested well during the night, which is a good sign that you’ve got way too much on your mind.

If you’ve got so much to do that you can’t even shut your mind down when you’re laying in bed, you’re too busy.

5. The Most Exercise You Get Is Sprinting from One Commitment to the Next

It’s proven that exercise promotes healthy lives. If you don’t care about that, that’s one thing. If you’d like to exercise, though, but you just don’t have time for it, you’re too busy.

If the closest thing you get to exercise is running from your office to your car because you’re late for your ninth appointment of the day, it’s time to slow down.

6. You Dread Getting up in the Morning

If your days are so crammed full that you literally dread even starting them, you’re too busy. A new day should hold at least a small level of refreshment and excitement. Scale back until you find that place again.

7. “Survival Mode” Is Your Only Mode

If you can’t remember what it feels like to be ahead of schedule, or at least “caught up”, you’re too busy.

So, How To Get out of Busyness?
