My experience shows me that these have an effect and that the long-term phenomenon rising from there often find results in the infringement of our melatonin output which allows us to sleep. Further more, specific rhythms and harmonies do have a very specific effect on the nervous system and the findings relating to it are used today for multiple medical/healing uses as well as for weaponized intent. Sound can bind or break things, especially molecules and rhythms are used to synch or do the exact opposite when it comes to, for instance, binding our genetic heritage.
Namaste :)
Well, when it comes to melatonin production, I'd say that is more because of the blue light monitors put out, not because of games.
The rest, I have no clue and I will not even try to claim I have, but sounds interseting and might be worth a future video ;)
