Most adults in the world are overly tired, but they don’t do much to correct the situation. According to a recent global sleep survey, eight in 10 adults want to improve their quality of sleep, but 60% of those haven’t received medical help or treatment. The reasoning is fairly simple. Most don’t consider sleep issues to be a serious problem, don’t know how to make the necessary changes, or think the cost of treatment is too high. The survey was conducted by health technology company Philips, headquartered in Amsterdam. It included interviews with 11,006 respondents in Australia, Brazil, Canada, China, France, Germany, India, Japan, the Netherlands, Singapore, South Korea, and the United States.
