More than half the UK population has struggled with sleep during the lockdown, a survey suggests.

King’s College London researchers said sleep problems were more common in people facing financial hardship, while two in five reported having more vivid dreams than usual.

Some people slept for longer than usual, but without feeling rested.

The findings are based on online interviews in late May with 2,254 UK residents in the 16-75 age bracket.

The study was carried out by market research company Ipsos MORI and King’s College London.
