A recent study found no significant association between postmeal glycemic response and length of sleep period; however, when the nutritional content of the breakfast meal was also considered, a significant interaction was found. Specifically, longer sleep periods were tied to lower blood glucose after high-fat, high-carbohydrate breakfasts, indicating better blood glucose control.

The researchers also found a significant link between glycemic control and sleep efficiency — the ratio of time asleep to total length of sleep period. Participants who slept more efficiently also experienced lower than usual postprandial blood glucose. The investigators noted that this was driven more by sleep onset than sleep offset.
