6. Drink less alcohol
Alcohol consumption has obvious impacts on memory ability. People who drink regularly make around 30 per cent more memory mistakes in daily life than those who don’t drink. Alcohol works to prevent transfer of short-term memories to long-term and even reduces the size of brain cells.
After a heavy night of drinking, it’s possible to have no memory of events. This is due to a memory-affecting chemical in the brain called glutamate, which is extremely susceptible to alcohol.
