It’s that time of year again. Thousands of households around the country are in the grips of ‘back to school’ fever and many of the mums and dads are determined to get their children back in to the right routine as the summer holidays draw to a close.
We spend a third of our lives doing it. So, why is sleep so important?
An easier way to understand why sleep is so critical is to actually think about what would happen if we didn’t sleep. We are always telling the children that they need to be in bed by a certain time and that they must get enough rest for whatever activity it is they have ahead of them the next day. But what’s the science behind this?
Lack of sleep affects the brain and its ability to function; it affects concentration and our attention span. Sleep is one of the few things we all have in common yet it continues to baffle scientists the world over. We need enough sleep to maintain normal levels of cognitive skills such as speech, memory and thinking and if we don’t get enough rest, our sense of time and judgement as well as our emotions are all impaired!
After a good sleep everything inside gets the boost, which is required for the next day ahead. The right amount of sleep helps to regulate the hormones that control appetite and even boosts the immune system. Sleep helps us feel happier and less cranky! And one of the things that is most important for the younger folk as they head back in to another academic year, it allows us focus, learn and make good decisions.

So, how much sleep do we need?
This is widely debated but in reality, it really differs from one individual to another as some people genuinely need a lot less or more sleep than others. Most studies advise that we need seven to eight hours daily. In an article I read recently, Jim Horne from Loughborough University’s Sleep Research Centre gave a simple answer: “The amount of sleep we require is what we need not to be sleepy in the daytime.”
It’s getting late. Goodnight All!
