## Why Sleep Eludes Some
Tired people often can't stop scrolling phones before sleep despite being exhausted.

> Lire son téléphone n'est pas suffisant, mais c'est pourtant bien plus accessible
## Cognitive Cost Difference
Reading activates more brain areas than scrolling, requiring memory work and cognitive effort.

> Le coût cognitif de la lecture est plus important que de regarder Instagram
## Instant Reward vs Delayed Benefits
Smartphones offer immediate dopamine rewards while books provide slower mental calm.

> Ces réseaux-là sont hyper récompensants, ça vous fait plaisir
## Solution for Better Sleep
Choose books that bring real pleasure to overcome phone scrolling habits before sleep.

> Il faut que vous retrouviez ce même plaisir
## Key takeaway

Tired people often can't stop scrolling phones before sleep because smartphone use has lower cognitive cost than reading books, according to psychiatrist Pierre-Alexis Geoffroy.
