Forget the worms and bring on the nightlife
At first, there was little difference between the early birds and night owls. An hour and a half after waking, members from both groups were equally alert and showed no difference in attention-related brain activity. But fast forward 10 and a half hours, and that was no longer the case. The night owls were more alert, performed better on a reaction-time task requiring sustained attention and showed increased activity in brain areas linked to attention. Unfortunately for the early birds, they didn’t get this late-day pick-me-up. Researchers concluded that faster activation of sleep pressure appears to prevent early risers from that natural energy jolt.
