A father of a newborn child produces less testosterone...
From what I know this is not explained by just sleep deprivation. So here we have no direct chemical transfer altering the physiological state of a man via external stimulus.
So if a baby can chemically alter a father, why can't highly stimulating lights and sounds?
Many years back I had a pretty strong detox from smartphones and videogames lasting about 2 years. When I first played a mobile game, I was so stimulated by it I found it hard to sleep properly for the first few weeks of playing. Later on my brain adjusted but now I probably have some kind of habitual need for dopamine...
