00:00:02,410 --> 00:00:07,816
Ten o'clock at night. The house is dark, but the screens are still glowing.

2
00:00:08,545 --> 00:00:12,574
Reading from a screen before bed isn't the same as reading a book.

3
00:00:15,214 --> 00:00:20,745
In the lab, those readers fell asleep later and had lower melatonin levels.

4
00:00:24,008 --> 00:00:28,900
Their body clock shifted, leaving them less alert the following morning.

5
00:00:30,808 --> 00:00:35,571
Lose sleep in the evening and you'll feel it at the wheel the next day.

6
00:00:37,213 --> 00:00:41,838
Paper instead of a screen in the evening. A clearer head the next day.
