Exam weeks look like a different person in the data.
One night, drawn
A typical night from the ring: deep sleep at the bottom, awake at the top.
The diary
Night 5
Revision until 00:50, then forty minutes of my phone telling me I should be revising. The ring has me asleep at 01:34.
Night 14
Exam day. Slept 4h 10m. Felt fine until the second paper, then read the same question five times.
Night 22
Slept eleven hours on Saturday. The app calls it a ‘recovery night’. My flatmate calls it a waste of a Saturday.
