Duke-NUS study: Segmented sleep can raise alertness but also risk of diabetes

Researchers from Duke-NUS Medical School have found that teenagers who observed a segmented sleeping pattern tend to be more alert and have better memory and mood than those who sleep 6.5 hours continuously in a stretch. However, the blood sugar level for these segmented sleepers may be 50 per cent higher than the continuous sleepers, putting them at higher diabetes risk.
