It turns out that fragrance can really improve memory.

A study published in Frontiers in Neuroscience by the University of California, USA, shows that smelling fragrance before going to bed is not only good for improving memory, but may also help prevent Alzheimer's disease. In other words, smelling fragrance is helpful for improving memory.

This experiment was conducted by researchers at the University of California, Irvine, USA. They selected 7 representative essential oil fragrances (lavender, rose, orange, eucalyptus, lemon, mint, and rosemary) for the experiment. Among them, 43 elderly people aged 60 to 85 participated in the experiment, divided into a smelling group and a non-smelling group. The study found that by continuing for 6 months (smelling 1 smell for 2 hours every night before going to bed), the memory of the participants can be improved by 226%.

This may be because the sense of smell responsible for perceiving odors is different from other senses and can directly communicate with organs such as the hippocampus and amygdala. Among them, the hippocampus is responsible for memory and the amygdala is responsible for emotions, just like we are easily triggered by fragrance Appetite, even after smelling a certain smell, we will recall the past events that happened before. This is because the olfactory nerves that perceive odors are very close to the organs that control instincts and memory.
