What can heavy, compulsive phone use affect?
Three areas researchers keep returning to. The evidence is stronger for some than others.

01 · Productivity
Attention gets cut into pieces.

≈ 30 min
it can take to fully recover from an interruption
These figures describe screens in general, so read them as context for phone use, not proof of what phones do. A 2003–04 study found about 2.5 minutes.

02 · Habits
Checking can become automatic.

In the study, people described their checking as overuse and an annoyance, not addiction. Habits also have benefits.

03 · Mental health and wellbeing
Sleep and mood show links, not proof.

Both are associations from observational and self-reported data. They don't show that screens alone cause these outcomes, and effects vary between people.

These can overlap. They don't affect everyone the same way.
