Effects of an 8 hour sleep and what modulates our circadian rhythm

May 3, 2021

I have recently become a big nerd when it comes to analysing my sleep efficiently and it's all thanks to the book ‘why we sleep’ by Matthew Walker.

Here's a little insight I found out about the necessity of having a minimum 8 hours sleep and how our natural hormones and byproducts help control our circadian rhythm.

Our circadian rhythm is known as our wake and sleep cycle. This cycle is individualised and is influenced by Melatonin which is a natural hormone and adenosine which is a byproduct of our body’s energy consumption.

Melatonin is light sensitive. The pineal gland is prompted to release melatonin with darkness which inhibits the brain's alertness and initiates sleep.The smallest sight of light inhibits the release of melatonin which is why we begin to wake up to the sunrise.

Adenosine on the other hand slowly increases throughout the day. As we use energy there is an increase of adenosine in our bloodstream this creates a sensation of tiredness and sleepiness which marks the beginning of the sleep process. Throughout sleep our body slowly eliminates adenosine and it is believed to take at least 8 hour to remove. Thus if not receiving 8 hours sleep we wake up with adenosine already in our bloody stream and therefore can feel tired earlier within the day (Adenosine sleep deprivation).

So now you know a little more about your sleep, do yourself a favour and give this book a read. You'll be amazed to find out all the amazing benefits of getting a good night's rest every night!.
