Study: Electronics don't affect our sleep
Author: Jonathan Warren
As technology has developed over the years, the impact of electronic gadgets on our health and sleep quality has been debated. However, new research has offered evidence to suggest that these gadgets aren't the root cause of the decline in sleep quality in our beds.
After examining data from 1992, 1997 and 2006, scientists at the University of Sydney found that Australians slept an average of just ten minutes more each night in 2006 than they did 14 years prior - an increase from eight hours 20 minutes to eight hours 30 minutes.
The findings, published in this month's Medical Journal of Australia, showed that despite concerns over the light radiated by televisions, computers and mobile phones and its supposed effect on the human body, there was little difference in sleep quality over the years. Some experts have argued that the light produced by electronic gadgets leads to slower production of the sleep-inducing hormone melatonin, meaning the more we integrate these electronic devices into our lives, the more our sleep could be affected.
The lead authors of the research concluded: "Public health concerns over declining sleep duration do not appear to be warranted. Investigation of possible changes in quality of sleep is required."
