The Big Sleep Survey 2010 will remain open until the end of September. The data will then be given to scientists at the Woolcock Institutein Sydney to be analysed scientifically for significant results. This process is expected to take many months, and should result in a peer-reviewed paper in a scientific journal.
In the meantime, the Big Sleep Survey team has done its own ‘non-scientific’ analysis of the data so we can get an idea of what the results may be – it’s a bit like peaking into the box before Christmas.
Please note that these results have not been scientifically verified – find out more about how science works .
WHO DID THE SURVEY?
OUR SLEEP HABITS
When we take gender into consideration, the figures change somewhat, with women more likely to feel tired than men- 58% compared to 47%. Not surprisingly, women are more likely to say they are not getting enough sleep.
The average night sleep of people doing the questionnaire was 7 hours, but the range was broad. Researchers will probably get a more accurate answer from analysing the Sleep Diary results.
NAPS AND SLEEPING IN
While we might not be a country of nappers, we do like to make up for it at the end of the week: 43% of participants said they would always sleep in on the weekend.
And when Monday rolls around, almost half of us need to set an alarm in order to get out of bed in time to make it to work.
DO WE SLEEP ALONE?Half of those who took part in the Big Sleep Survey 2010 share a bed, with 48% stating they have a bed partner, 42% saying they didn’t, and an intriguing 10% admitting they had one occasionally.
Almost 25% of participants with pets had them in their bed at least a few nights a month. Yet only 9% of those with children had a child in their bed that often. Do pets make better bed fellows? Are children easier to train? Or maybe they take up too much space?
TECHNOLOGY IN THE BEDROOM
Is this modern technology in our bedrooms affecting our sleep? That question is too complex to answer in this simple analysis; we’ll have to wait for the sleep scientists to do their work before we have a definitive answer.
But we can say that while almost 40% slept with an electronic device that could wake them, it seems the majority of people are never woken up by a ‘beep’ or a ‘brrring from their mobile in the night. Only 1% of participants said they were woken every or almost every night by an electronic sound or alert.
And it’s the same with checking messages in the middle of the night. Although 4% of people checked their messages every night, almost 90% of participants said they would never or rarely do so.
Is the lure of modern technology keeping us from sleeping? Almost a quarter of people admit to watching TV, using their computer or playing with their mobile during the hours that they should be sleeping. Whether they are more likely to have problems with insomnia, or daytime drowsiness we’ll have to wait to see.
STATE VS STATE
Tasmania and Western Australian were the only states where participants were more likely to say they were getting the right amount of sleep.
Northern Territorians were most likely to feel tired – almost a third of them reported feeling tired most days. Perhaps to compensate for this, 55% of Northern Territorian participants say they sleep in on the weekends, compared with only 38% of Queenslanders who are the least likely to try to catch up on sleep.
It might have had something to do with the Big Sleep Survey coinciding with the federal election that participants in the ACT were the most likely to feel irritated at least a few times throughout the month of August. But, South Australians take the hat for all out grumpiness – over 8% of the South Australians who did the questionnaire reported feeling irritable every or almost every day.
THE REAL ANSWERS ARE STILL TO COME
While this simple analysis gives a nice overview of the data collected by the Big Sleep Survey 2010, it’s when the scientists do their work that we will have truly accurate and meaningful results.
Is this the biggest sleep survey ever? We’ll have to wait for the sleep scientists at the Woolock Institute to say for sure. But we’re erring on the side of saying YES!
