00:00:02,415 --> 00:00:07,133
At 4 am, the body is at its lowest point of the day.

2
00:00:08,420 --> 00:00:14,665
Core temperature falls to its lowest point. Alertness falls with it.

3
00:00:15,405 --> 00:00:23,841
Reflexes slow down. At 100 km/h, half a second means 14 metres.

00:00:24,579 --> 00:00:30,607
Between 2 and 6 am, sleepiness-related crashes are most frequent.

5
00:00:31,346 --> 00:00:37,650
It is not weakness. It is the body's rhythm, and the body is right.

00:00:38,398 --> 00:00:42,831
You don't fight the body's lowest point. You wait it out.
