I usually switch my families to day mode for 3 hours in the evening make them sleep for a short while they refresh quicker then before i go to sleep i switch them back to day mode they seem fine with it and if they sleep during my imposed day mode they quickly change from exhausted to tired to elated. Im not sure if it affects them at all but it makes them happily eat work and play after 20 minutes or so when i switch back to night mode i just put them all to bed. Has anyone else tried anything similar? Causes less eye strain too.
