Why is Sleep So Important?

Sleep is something we all need, it is one of the main pillars of health alongside nutrition and exercise. On average, an adult will spend at least eight hours of the day asleep, this leads to around 25 years asleep in their lifetime (give or take a few years). We know that if we don’t get enough sleep, we tend to be grumpy, moody, our appetite suffers and so does our concentration and motivation. Or maybe that’s just me.

Sleep goes hand in hand with well-being and getting a good night’s sleep is essential to your health. While we are asleep our body is busy doing its night time jobs. These include:

  • Healing damaged cells

  • Boosting your immune system

  • Recovering from the day’s activities  

 And yet, with all this going on in our bodies and busy lifestyles, many of us just don’t get enough sleep. People think they can do without sleep, run on fumes and just get through the day. So, the question is, why is sleep so important? Why do we need good quality sleep and how much do we need?


Research recommends at least seven to eight hours of sleep each night for an adult to be well rested. Good quality sleep can help protect your mental and physical health as well as your safety and improve your quality of life. The way you feel when you wake up depends on how much and the quality of sleep you have had the night before.


Good sleep is essential to healthy brain function as well as emotional well-being. Basically, sleep helps your brain work properly. When you sleep your brain focuses on preparing for the next day, creating new pathways to help you learn and remember information. Sleep also helps you make decisions, improves your concentration and helps with creativity. It’s hard to focus on what you are doing when you haven’t had a good night’s sleep.

 On the other side, if you haven’t had enough sleep you can have trouble solving problems, making decisions, controlling your emotions and behaviour as well as coping with changes that occur.


Sleep plays an essential role in your physical health. Sleep helps to maintain balance of the hormones that control your appetite as well as affecting your bodies reaction to insulin. It supports healthy growth and development and keeps the immune system healthy.

 If you’re not getting enough sleep you can have an increased risk of heart disease, high blood pressure, kidney disease, stroke and diabetes. There is also an increase in the risk of obesity and a decrease in the performance of your immune system, meaning you tend to get sick more often than not.


If you feel like you are not getting enough sleep, here are some helpful tips to start you on your journey to dreamland:

  • Go to bed and wake up at the same time everyday

  • Turn off electronics at least an hour before bed

  • Create a comfortable sleeping environment

  • Use your bed for sleep only (as well as that other thing…..)

  • No caffeine after 3pm
