Is Sudoku Before Bed a Good Idea?

Bedtime Sudoku can be enjoyable if you find it relaxing and it does not keep you up. If an unfinished grid makes you want to continue, an earlier puzzle break may suit you better.

Protect the time you intended to sleep

The National Heart, Lung, and Blood Institute recommends quiet time before bed and avoiding bright artificial light. That guidance supports a gentle wind-down routine; it does not establish Sudoku as a sleep treatment.

Choose an Easy puzzle if you want something familiar. Decide when to put it away before you start, and leave the remaining cells for another day. A completed grid is not worth turning a short break into a later bedtime.

Paper can make the choice simpler

A printed Sudoku lets you solve without a phone screen. Preview the daily sheet if you only want one puzzle, and use a comfortable reading light so you can see the grid clearly.

If you use a screen, remember that a warmer colour setting does not guarantee that the activity will help you sleep. Pay attention to whether you feel ready to stop, rather than treating a display setting as permission to keep playing.

Notice when it stops being restful

• If you are getting frustrated, put the puzzle away.
• If you keep checking the timer, leave the time comparison for another session.
• If you are tempted to start another grid, return to the bedtime you planned.

Sudoku does not have to be part of your evening. Reading, another quiet activity or simply stopping for the day may be a better fit for you.

When sleep difficulties persist

If trouble sleeping is ongoing or affects your daytime life, discuss it with a health care provider. The NHLBI's insomnia guidance describes treatments such as cognitive behavioral therapy for insomnia. A puzzle should not delay getting appropriate help.

If you want to play at another time, today's Sudoku is ready when you are.
