Although writer Karen Emslie argues that a continuous block of sleep is a modern phenomenon, the Sleep Health Foundation has concluded that Australians are not embracing the importance of sleep after conducting a study with 1,500 participants. The study results found that optimal sleep conditions do not exist in many Australian bedrooms, leading to poor sleep quality.
Professor Dorothy Bruck, a psychologist who ran the study, explained to the Daily Mail that "A quiet and comfortable bedroom environment is an obvious prerequisite for maximising sleep quality", while a relaxed mind is also crucial. However, study participants revealed that the bedroom is transforming into an office, with 45 per cent using their laptops and electronic devices in bed, while significant numbers reported temperature, and uncomfortable clothing and bedding as causes of poor sleep.
Professor Buck said that the blue light from tech devices is mainly a problem when held close to the face, as it can prevent the human body-clock from functioning properly. Furthermore, Professor Buck advised that beds should only be used for sleep and intimacy to guard against sleep deprivation; but, the study shows that "so many people were using their sleep sanctuary to email, cruise the web and watch movies, all activities that are not conducive to sleep."
Professor Buck quoted one survey that found that Australians were getting, on average, one hour less sleep a night than they needed—about 7.3 hours when they should be getting 8.25. However, Australia is not the only population deprived of sleep, as overseas studies show that people are sleeping less than previously.
The Foundation's research warns that Australia's "widespread failure to prioritise sleep" can lead to significant physiological harms, including diabetes, cardiovascular disease, depression and obesity. Professor Buck recommended the following tips for a healthy sleep routine:
1. Wind down sufficiently before you go to bed.
2. Refrain from drinking coffee after 2pm
3. Consistently go to bed at a regular time.
4. Unless you have special sleep requirements, avoid sleeping for more than 8.5 hours.
