Three Key Elements to a Good Night's Sleep

You probably ask yourself all the time what makes a good night’s sleep? If you google it, you’ll most likely see lists upon lists of top ten tips or the 5 best secrets to a good night’s sleep. Whilst these lists probably have great ideas, they may be redundant without understanding the key elements that make a good night’s sleep.

We’ve narrowed it down to three key elements for a good night’s sleep:

1. Duration
2. Continuity
3. Depth

Now you know the three elements let’s expand on what they are so you have a basic understanding and can apply those great tips you see everywhere including our Instagram 😉.

1. Duration

Duration refers to the length of time that you sleep for, your sleep needs to be long enough that when you wake up the next day you are feeling refreshed and alert. Generally speaking, for an adult this is between 7-9 hours of sleep, with the length being longer for teenagers and young children.

2. Continuity

Your sleep needs to be long and uninterrupted, even if you are still getting your required hours of sleep a night if you are waking up multiple times this can affect the overall quality of your sleep. There are four stages of sleep that humans go through each night:

1. Stage 1 – A light sleep that only lasts a few minutes and is a transition period between wakefulness and sleep. Our body and brain start slowing down.
2. Stage 2 – Occurs when the body starts transitioning from a light sleep to a deeper sleep. Our bodily functions continue to slow down, muscles relax, eye movement stops and our body temperature reduces. On top of this brain waves slow down further.
3. Deep Sleep – Our heart rate and breathing rate are at their lowest during this part of the sleep cycle. The muscles and eyes are also very relaxed, and the brain waves become even slower.
4. REM (Rapid Eye Movement) Sleep – Occurs roughly 90 minutes after falling asleep, this is closer to a state of wakefulness with our breathing and heart rate increasing as well as our eyes start to move rapidly side to side behind our eyelids, this is when most of our dreams occur.

As you can see our body slides through different and important stages of sleep each night and can do this multiple times, so if you are repeatedly waking up during the night you are disrupting your bodies sleep cycle.

3. Depth

This ties in with the stages of sleep we touched on above when talking about sleep continuity, you want your sleep to be deep and restorative. This means we especially want to make sure we are reaching the third and fourth stage of sleep known as slow wave sleep.  Slow wave sleep is attributed to play a pivotal role in brain restoration and recovery as well as memory consolidation, whilst also producing human growth hormone which repairs tissues and cells in our bodies. All very important for us to be functional humans the next day.

Now you are equipped with the understanding of the key factors making up a good night’s sleep, you can now start creating a sleep routine that will aid you in sleeping the required amount and protecting it from interruption.
