Sleep is one of the most powerful tools you can master. But how can you master something you don’t even know is happening in real-time? On this page, we’ll explain why sleep is so valuable - but not before we touch on common misconceptions, how to rewire your brain to respect deep sleep, and sleep’s impact on your health.
Misconceptions About Sleep; Fixing How we Interpret Rest
We, as humans, share many core needs biologically. Sleep is one of those needs, no matter who you are or what you do. You may tell yourself “I function well on just a few hours of sleep” or “It doesn’t affect me”; some people even flaunt their lack of sleep to demonstrate how ‘hard working’ they are. However, none of these are true. Sleep is productive, and something you shouldn’t miss. While you sleep, your brain cleanses itself from sticky toxic proteins, increasing your expected life span. Another common misconception is equating time in bed to time asleep. Let’s say you go to bed at 11pm and wake up at 7am (“I’ll get about 8 hours of sleep, perfect”). But it takes time for us to fall asleep. We often wake up or fall out of sleep through the night without even realizing it. If you don’t believe me, try using a sleep tracking app for a week and you’ll notice this (unless you are already a master sleeper). Generally, the rule is, If you want to sleep x amount of hours, you’ll need an extra 1-2 hours in bed on top of that to adjust for unexpected disturbances.
Why Sleep is So Valuable
In this section we have four lists you can review that will give you a general sense of how important sleep is for everything we do in life.
Sleep for Preventing disease and health problems

“Insufficient sleep is also associated with lower levels of leptin, a hormone that alerts the brain that it has enough food, as well as higher levels of ghrelin, a biochemical that stimulates appetite. As a result, poor sleep may result in food cravings even after we have eaten an adequate number of calories.” Source
Heart attacks are more likely to occur when daylight savings happens, reverse for when we spring forward. (Less sleep, more Sleep.)
We all know that sleep is important for our health, but having a good understanding of why that is
Sleep for Better Learning
The hippocampus - Responsible for short term learning, like an SD card with limited space, or computer RAM for your brain.
The neo-cortex - Responsible for long term storage
Sleep gives you more room for short term storage, by moving what you learned it into the neo-cortex. Sleep is crucial for studying and learning. Sleeping after learning cements what you are studying or learning. Early night NREM sleep is superior for cementing information.
Non-rapid eye movement (NREM) sleep: about 80% of sleep. We do not dream in NREM sleep, we are very still and relaxed. A perfect time for your brain to truly process what has taken place during the day
Good sleep will improve your capacity for knowledge.
Sleep for Motor Skill Enhancement
This ties into NREM sleep and learning
Motor skills such as instruments, exercise and sports are all improved by a well rested brain.
Example: I am a drummer, when I started improving my sleep, my flow and comfort level on the drum set improved. Beats and timings I struggled on the day before got a lot better the day after. Especially after getting stuck on something.
Sleep for Self-Love and Mental Health
Sleep is without a doubt a key pillar in establishing good mental health and development of self love.
Sleep deprivation can cause sudden mood changes and increased levels of anger. When sleep deprived, our brain does not have the capacity to adequately suppress the amygdala (the emotional control centre of our brains). This can be a source of stress and irritation. A fairly calm and manageable day could turn into a stressful and turbulent one when your brain is not well rested.
Therefore, staying consistent with your sleep routine will have you feeling better daily. That in and of itself is an act of self-love: sacrificing time you could have spent elsewhere to help out your brain.
Once you establish a good sleep routine, you’ll notice how much better you feel in all aspects of life, especially if you haven’t been practising good sleep ‘hygiene’. Speaking of good sleep hygiene, let’s get into that in the next section.
Once you establish a good sleep routine you will notice how much better you feel in all aspects daily, especially if you haven’t been practising good sleep ‘hygiene’. We’ll talk about that in the next few sections.
Sleep optimization strategies
If you want to achieve better sleep tonight here are some great strategies:
Avoid Blue light before going to bed: If you have a bad habit of using your phone before sleeping, it would be in your best interest to stop. Blue light, the kind of light that comes from our devices disrupts our natural circadian rhythm and melatonin release, a hormone that tells our body that it is time to shut down for the day. The experts say 1-2 hours, however I try and make sure I’m staying away from blue light 30 mins before sleeping and it works.
Aim for regularity: To complement your circadian rhythm going to bed at the same time and waking up at the same time most days will set your body on a schedule, you will be tired when its time to sleep and ready to get up when it’s time to get up. This makes routine much easier.
If you can’t sleep get out of bed: This may sound contrary to what has already been said but it’s true, especially if you’re adjusting to a new sleep schedule. You have to associate your bed with sleep, during the day try to not lie down on your bed, the only time you are in your bed is to sleep.
Go to bed earlier
Stretch before you sleep
Make sure you are hydrated before you go to bed
Look into melatonin supplements (not medical advice)
Conclusion
Sleep is the foundation for everything you do in life. We live in a strange time where people overlook their health because they think it gives them an advantage in their career or personal success, but this is simply untrue. Sleep is an asset and we need to learn how to utilize it to the fullest. I hope that this article was of use to you, and that you start getting better sleep tonight.
