“Uncontrolled blood sugar levels can cause levels of glucose to rise in the saliva and this creates a breeding ground for bacteria, increasing the risk of gum disease and dental decay.”
Severe gum disease can then negatively affect blood sugar control and can increase the chances of diabetes complications happening.
In findings presented in 2016 at the European Association for the Study of Disease annual meeting, it was revealed people who took daytime naps longer than an hour were 45 per cent more likely to have type 2 diabetes compared to those who napped less or not at all.
The study authors added it’s not likely that napping during the day actually causes diabetes.
But they said it could be a warning sign of an underlying health problem, such as sleep deprivation or depression, which are all conditions associated with an increased risk of diabetes.
