Why is sleep important?
Sleep Awareness Week – 11-18 March
So many people I see in clinic struggle with the effects of poor sleep. So, in aid of National Sleep Awareness Week this week, I want to talk to you about why a good sleep is so important and how you can go about getting it!
A good night’s sleep is as important to health as eating the right things and exercise. Your physical and emotional wellbeing depend on getting enough. Yet we’re living in sleep-deprived times. Some people are even competitive about how little sleep they’re getting, like dragging yourself through the day on four hours’ rest is a badge of honour. Scientists even say we’re now getting an hour or two less sleep each night than we were 60 years ago. And the effect on our bodies is not good.
The amount of sleep each person needs varies. Waking up feeling refreshed in the morning is a good indicator and so is being able to wake without an alarm. If you need an alarm to wake up, you are not getting enough sleep. If you don’t get enough sleep, you may not be able to concentrate properly, and become irritable or agitated. You may also have blurred vision, be clumsy, become disorientated or slow to respond, and have decreased motivation. And, on top of that, if you’re tired and cranky, you are significantly less likely to make the best food choices.
You might be surprised to learn that, in a computer simulated driving test, those who had had just a few hours sleep were more dangerous on the (virtual) road than the people who had had a few drinks! In fact, the majority of road accidents are caused by tiredness.
The purpose of sleep is to rest and recover – and to allow the body to repair itself. These maintenance and repair processes take 7 to 9 hours. Adults need between 7 and 9 hours per night – regardless of what you think you have trained yourself to get by with.
But just how do you get a good night’s sleep? Join me tomorrow….
