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.

11 Important Things to Remember When Changing Habits

11 Important Things to Remember When Changing Habits

Most gurus talk about habits in a way that doesn’t help you:

You need to push yourself more. You can’t be lazy. You need to wake up at 5 am. You need more motivation. You can never fail…blah blah “insert more gibberish here.”

But let me share with you the unconventional truths I found out:

To build and change habits, you don’t need motivation or wake up at 5 am. Heck, you can fail multiple times, be lazy, have no motivation and still pull it off with ease.

It’s quite simple and easy to do, especially with the following list I’m going to show to you. But remember, Jim Rohn used to say,

“What is simple and easy to do is also simple and easy not to do.”

The important things to remember when changing your habits are both simple and easy, just don’t think that they don’t make any difference because they do.

In fact, they are the only things that make a difference.

Let’s see what those small things are, shall we?

1. Start Small

The biggest mistake I see people doing with habits is by going big. You don’t go big…ever. You start small with your habits.

Want to grow a book reading habit? Don’t start reading a book a day. Start with 10 pages a day.

Want to become a writer? Don’t start writing 10,000 words a day. Start with 300 words.

Want to lose weight? Don’t stop eating ice cream. Eat one less ball of it.

Whatever it is, you need to start small. Starting big always leads to failure. It has to, because it’s not sustainable.

Start small. How small? The amount needs to be in your comfort zone. So if you think that reading 20 pages of a book is a bit too much, start with 10 or 5.

It needs to appear easy and be easy to do.

Do less today to do more in a year.

2. Stay Small

There is a notion of Kaizen which means continuous improvement. They use this notion in habits where they tell you to start with reading 1 page of a book a day and then gradually increase the amount you do over time.

Advertising

But the problem with this approach is the end line — where the “improvement” stops.

If I go from reading 1 page of a book a day and gradually reach 75 and 100, when do I stop? When I reach 1 book a day? That is just absurd.

When you start a habit, stay at it in the intensity you have decided. Don’t push yourself for more.

I started reading 20 pages of a book a day. It’s been more than 2 years now and I’ve read 101 books in that period. There is no way I will increase the number in the future.

Why?

Because reading 40 to 50 books a year is enough.

The same thing applies to every other habit out there.

Pick a (small) number and stay at it.

3. Bad Days Are 100 Percent Occurrence

No matter how great you are, you will have bad days where you won’t do your habit. Period.

There is no way of going around this. So it’s better to prepare yourself for when that happens instead of thinking that it won’t ever happen.

What I do when I miss a day of my habit(s) is that I try to bounce back the next day while trying to do habits for both of those days.

Example for that is if I read 20 pages of a book a day and I miss a day, the next day I will have to read 40 pages of a book. If I miss writing 500 words, the next day I need to write 1000.

This is a really important point we will discuss later on rewards and punishments.

This is how I prepare for the bad days when I skip my habit(s) and it’s a model you should take as well.

4. Those Who Track It, Hack It

When you track an activity, you can objectively tell what you did in the past days, weeks, months, and years. If you don’t track, you will for sure forget everything you did.

There are many different ways you can track your activities today, from Habitica to a simple Excel sheet that I use, to even a Whatsapp Tracker.

Peter Drucker said,

“What you track is what you do.”

So track it to do it — it really helps.

But tracking is accompanied by one more easy activity — measuring.

5. Measure Once, Do Twice

Peter Drucker also said,

“What you measure is what you improve.”

So alongside my tracker, I have numbers with which I measure doses of daily activities:

For reading, it’s 20 pages.
For writing, it’s 500 words.
For the gym, it’s 1 (I went) or 0 (didn’t go).
For budgeting, it’s writing down the incomes and expenses.

Tracking and measuring go hand in hand, they take less than 20 seconds a day but they create so much momentum that it’s unbelievable.

6. All Days Make a Difference

Will one day in the gym make you fit? It won’t.

Will two? They won’t.

Will three? They won’t.

Which means that a single gym session won’t make you fit. But after 100 gym sessions, you will look and feel fit.

What happened? Which one made you fit?

The answer to this (Sorites paradox)[1] is that no single gym session made you fit, they all did.

No single day makes a difference, but when combined, they all do. So trust the process and keep on going (small).

7. They Are Never Fully Automated

Gurus tell you that habits become automatic. And yes, some of them do, like showering a certain way of brushing your teeth.

But some habits don’t become automatic, they become a lifestyle.

What I mean by that is that you won’t automatically “wake up” in the gym and wonder how you got there.

It will just become a part of your lifestyle.

Advertising

The difference is that you do the first one automatically, without conscious thought, while the other is a part of how you live your life.

It’s not automatic, but it’s a decision you don’t ponder on or think about — you simply do it.

It will become easy at a certain point, but they will never become fully automated.

8. What Got You Here Won’t Get You There

Marshall Goldsmith has a great book with the same title to it. The phrase means that sometimes, you will need to ditch certain habits to make room for other ones which will bring you to the next step.

Don’t be afraid to evolve your habits when you sense that they don’t bring you where you want to go.

When I started reading, it was about reading business and tactic books. But two years into it, I switched to philosophy books which don’t teach me anything “applicable,” but instead teach me how to think.

The most important ability of the 21st century is the ability to learn, unlearn, and relearn. The strongest tree is the willow tree – not because it has the strongest root or biggest trunk, but because it is flexible enough to endure and sustain anything.

Be like a willow, adapting to the new ways of doing things.

9. Set a Goal and Then Forget It

The most successful of us know what they want to achieve, but they don’t focus on it.

Sounds paradoxical? You’re right, it does. But here is the logic behind it.

You need to have a goal of doing something – “I want to become a healthy individual” – and then, you need to reverse engineer how to get there with your habits- “I will go to the gym four times a week.”

But once you have your goal, you need to “forget” about it and only focus on the process. Because you are working on the process of becoming healthy and it’s always in the making. You will only be as healthy as you take care of your body.

So you have a goal which isn’t static but keeps on moving.

If you went to the gym 150 times year and you hit your goal, what would you do then? You would stop going to the gym.

This is why goal-oriented people experience yo-yo effect[2] and why process-oriented people don’t.

The difference between process-oriented and goal-oriented people is that the first focus on daily actions while others only focus on the reward at the finish line.

Set a goal but then forget about it and reap massive awards.

10. Punish Yourself

Last two sections are pure Pavlovian – you need to punish bad behavior and reward good behavior. You are the only person who decides what is good and what is bad for you, but when you do, you need to rigorously follow that.

Advertising

I’ve told you in point #3 about bad days and how after one occurs, I do double the work on the next day. That is one of my forms of punishments.

It’s the need to tell your brain that certain behaviors are unacceptable and that they lead to bad outcomes. That’s what punishments are for.

You want to tell your brain that there are real consequences to missing your daily habits.[3]

No favorite food to eat or favorite show to watch or going to the cinema for a new Marvel movie- none, zero, zilch.

The brain will remember these bad feelings and will try to avoid the behaviors that led to them as much as possible.

But don’t forget the other side of the same coin.

11. Reward Yourself

When you follow and execute on your plan, reward yourself. It’s how the brain knows that you did something good.

Whenever I finish one of my habits for the day, I open my tracker (who am I kidding, I always keep it open on my desktop) and fill it with a number. As soon as I finish reading 20 pages of a book a day (or a bit more), I open the tracker and write the number down.

The cell becomes green and gives me an instant boost of endorphin – a great success for the day. Then, it becomes all about not breaking the chain and having as many green fields as possible.

After 100 days, I crunch some numbers and see how I did.

If I have less than 10 cheat days, I reward myself with a great meal in a restaurant. You can create your own rewards and they can be daily, weekly, monthly or any arbitrary time table that you create.

Primoz Bozic, a productivity coach, has gold, silver, and bronze medals as his reward system.[4]

If you’re having problems creating a system which works for you, contact me via email and we can discuss specifics.

In the End, It Matters

What you do matters not only to you but to the people around you.

When you increase the quality of your life, you indirectly increase the quality of life of people around you. And sometimes, that is all the “motivation” we need to start.

And that’s the best quote for the end of this article:

“Motivation gets you started, but habits keep you going.”

Keep going.
