Screen Time and Sleep Impact: What to Change Tonight

Evening screen use can delay sleep onset and reduce sleep quality when it becomes stimulating and prolonged.

Practical cut-off

Set a screen stop time 30 to 60 minutes before bed. Use low light and calmer activities.

Why this works

Reducing late stimulation makes your wind-down predictable and supports cycle-based bedtime planning.

Conclusion

You do not need perfection; you need repeatable boundaries.
