For the study, the researchers examined the napping habits of 16,480 people and found that diabetes prevalence increased with napping frequency.
Those who regularly napped had a 26% greater risk of developing diabetes compared with those who never napped.

The researchers believe several factors may be behind the link, including an association between napping and reduced physical activity. 

In addition, napping during the day may disrupt night-time sleep which could have an impact as short night-time sleep duration has been shown to be associated with increased type-2 diabetes risk.

Lead researcher Dr Shahrad Taheri, from the University of Birmingham, said: ‘Our research provides us with an additional insight on the risk factors behind type-2 diabetes. 

‘As the number of people with type-2 diabetes keeps increasing, it is crucial that we do everything we can to help prevent people from developing the condition.’
