More than 80% of adults are now sleep-deprived, according to a survey, with the number of people needing to get up in the night having risen in recent years.
The survey from research firm GfK found that the average adult was waking up at a time when they felt worse about themselves than at any other time in their lives.
This was due to “a growing body of evidence that sleep quality and well-being have become worse for people with insomnia” and that the quality of sleep was negatively correlated with the severity of the condition, according the firm.
“It is becoming increasingly clear that the link between insomnia and poor sleep is not limited to sleep quality,” said Prof David C. Haines, who led the research.
He added: “People with sleep disorders have an overall poorer quality of life than those without, which can have a significant impact on their health.”
Prof Hains said there was growing evidence that poor sleep was a key contributor to depression, obesity and anxiety.
But there were some key findings about how sleep could be improved.
“The sleep that you get when you are sleeping is a pretty good indicator of how well you are doing in your job, whether you are happy or not,” he said.
Prof Caulfield, who was involved in the research, said the findings were “absolutely mind-blowing” but suggested that the most common way to improve sleep was by “just waking up more often”.
“I think that we need to change the way we think about sleep,” he added.
The survey found that people with sleep difficulties were more likely to feel isolated and isolated from the people around them.
Dr Hain of the GfL Sleep Research Centre said: “We need to realise that we are living in an increasingly connected society, and that a lot of our issues stem from that.”
