I have been participating in this study run by University College London or many months now, which involves filling out a questionnaire every month or so. Some interesting results are now emerging for instance:
“Quality of sleep has deteriorated by 39% over the past year. In March 2020, 13% of people were getting ‘very good’ quality sleep, but a year later this has decreased to 8%. Similarly, the number of people reporting ‘very poor’ quality sleep has doubled from 5% in autumn 2020 to 10% early this year. Certain groups are more likely to report poor quality sleep than others including people with lower household incomes, those with a mental or physical health condition, and those from ethnic minority backgrounds.”
