It's 10 am. The sun is high over the lake. After a night's sleep, the body is close to its peak.

00:00:09,910 --> 00:00:17,320
Sleep pressure is low, while the body clock is pushing towards the day. For once, the two forces pull together.

00:00:18,062 --> 00:00:24,129
After waking, the brain takes two to four hours to get going. By 10 am, we're there.

00:00:25,712 --> 00:00:29,797
Without a good night's sleep, there is no peak. Not even at 10 am.

5
00:00:33,015 --> 00:00:38,662
If you can choose when to leave, leave now. If you can't, at least you know.

00:00:40,608 --> 00:00:47,757
At 10 am, many are at their peak. But a good time of day doesn't make up for a short night's sleep. Leave only if you've slept.
