The BBC says:

Taking regular lunchtime siestas could increase the risk of developing Type 2 diabetes, according to research.

The study of 16,480 people, found those who napped were 26% more likely to get the condition than those who did not.

Several factors which may be behind the link included disrupted night-time sleep and an association between napping and reduced physical activity.

But a conference in Glasgow will hear that factors like genetics and being overweight are more significant.

The researchers will tell delegates at the Diabetes UK event that napping during the day may disrupt night-time sleep.

This could have an impact as short night-time sleep duration has been shown to be associated with an increased Type 2 diabetes risk.

Surprise, all they have shown is a correlation, not a causation but the BBC dresses it up as a causation, so claiming that "lunchtime siestas could increase the risk of developing Type 2 diabetes". This kind of "research" is in any case pretty pointless. You can come up with a zillion and one correlations between a zillion and one things you are apparently not supposed to like (and it seems that lunchtime siestas are the latest on that list) and a zillion and one health outcomes. It's all pretty trivial, and meaningless, stuff. Surprise, people with worse sleep patterns are correlated with people who have worse health. Who would have thought it.
