The Importance of Sleep
The average adult needs between 7-8 hours of quality sleep a night to maintain a healthy body.
That’s the key. Sure you feel you can manage on less, you can do all the things you need to in a day, have an early night now and then you’ll feel fine, but in reality your body will already be revealing just how sleep deprived you are.
Each night your body goes through different levels of sleep from light to deep. If you’re sleeping well, you can cycle through these different levels up to five or six times a night. It is during the deepest phase of sleep in each cycle that the good stuff happens.
Your body sets to work repairing itself, the Glymphatic system in the brain eliminates toxins, the growth hormone is released and cells are rejuvenated. Did you know that this is also when your memories are consolidated? Your brain prefers to do all this whilst you sleep and this is why it’s so important to get a Good Night.
So, what happens when you are aren’t getting enough sleep?
Well you’ll feel physically tired, you’ll have low energy, your metabolism will be disrupted, your decision-making will be slower, you’ll be more forgetful and your mood will be lower. You will certainly notice it when you look in the mirror because prolonged periods of sleep deprivation lead to premature ageing, as your skin loses its elasticity, is less plumped-up, less radiant and less quick to heal.
New research now shows that lack of sleep may also have a neurogenerative effect on the body, so sleep helps keeps the brain healthy as well as the body.
