Rose fragrance - '' medicine '' improves memory

According to a study published in Science on the 8.3th issue of the journal Science, German researchers discovered that rose scent can affect human memory while sleeping.

74 volunteers who participated in the study were instructed how to play highly focused games, such as finding matching cards when only playing one card at a time. While doing this game, some people smelled rose. Study participants then slept in an MRI tube to monitor resonance images from brain activity during sleep.

At stages during sleep, these volunteers smell the fragrance of roses. The next day, the volunteer team was checked again, and the researchers said that after a night of roses, the study participants remembered 97.2% of the cards they had flipped before they slept. If they can't smell the rose, they only remember 86% of the cards.

Experts said previous studies in some animals had similar results, for example, mice could recall their activities during sleep, while birds could hear singing melodies. when I'm sleeping.
