Reading vs. gaming: the never ending debate. Is one better than the other? Gaming, when used excessively and with addictive tendencies, can be detrimental to the brain. It can foster addiction, numb your brain and feelings, and when used in excess, can destroy personal, real life relationships. However, gaming also has positive effects on the brain. It can improve hand-eye coordination, can introduce children to technology, and can provide pain relief to patients undergoing painful procedures or those living with chronic pain.
