A study by the University of Valencia, which involved more than 450,000 individuals, indicates that reading printed paper books helps in understanding texts/passages much better than reading on electronic device screens.

It was also mentioned in it that a person who spends 10 hours reading paper books increases their chances of understanding texts/passages by 6 to 8 times, compared to a person who spends the same duration on digital devices.
