People of Norwich are guilty of switching lights on, flushing the toilet and waking up at least twice a night without a thought for their housemates trying to get a good night's kip, according to a survey.

The research, which looked at the sleeping habits of British people, found that 47pc of people in Norwich switch the light on in the bathroom at night and 48pc flush the toilet before returning to their bedroom.

It's no wonder the results also revealed that the majority of Norwich folk wake up feeling grumpy in the morning, with the city's residents waking up on average two times a night.

So how can you make sure to get a good night's sleep?

James Wilson, an independent sleep practitioner, said: 'The biggest obstacles are light, temperature and noise.

'Everyone's sleep pattern is different, but the average sleep cycle should ideally be 6 – 10 hours for adults.

'If we are outside of these cycles, we could be doing more harm than we realise.'

Turning the bathroom light on sends a message to the brain that it's time to wake up made worse by the shock of sitting on a cold toilet seat.
