| many more couples than you might think choose sleep separately for exactly the reasons shown by this data. It appears you didn't read past the first graph (which initially implies a reduction in sleep due to sharing a bed with his partner). But he then goes on to say this: Turns out, since we started sharing a bed, most nights I have the same amount of sleep as before. What follows is a further analysis leading to this conclusion: Whilst spending nights with my girlfriend results in less time in a state which Fitbit recognises as “lying in bed ready to sleep”, because we go to bed later and get up earlier, when I am in that state, I sleep better. So it's not that he's sleeping less, or more poorly while sharing a bed. That first graph is just a product of less time spent physically in bed. In fact, there's another graph he presents that shows basically the same amount of actual sleep while in bed, with or without his partner. Try not to read your own biases into other people's writing, and be very careful when skimming. It's a hard habit to break, I know, but it can really hurt you in life (no joke... misreading an email in a professional context can make for nasty mistakes). |
