University of Luebeck and Hamburg, Germany – Egyptian Center for Peng sedova University of Medicine recently published by the neuroscientist studies point out , sleep incense smell the roses, it helps to strengthen memory.

The study has been published on the 9th “Science” magazine. The researchers recruited 74 volunteers to enable them to play a computer memory game, remember the same two cards in their respective position on the screen, and then let them disguised dependent, inhalation of a rose incense. Half an hour later, researchers volunteers into the room to sleep, and continue to spread to the room rose aroma, while observing their brain activity during sleep.

After the volunteers woke up, before the memory card memory location, the accuracy rate of 97%. However, the second time and sleep without flowers, they recall the exact rate of only 86%.

Usually people go to sleep after 20 minutes into the depth of sleep, this stage more than one hours generally sustainable and may be repeated. The results showed that volunteers only in the depth of sleep stage rose fragrance smell, memory can be improved significantly.

The researchers explained that this is because the depth of sleep, the cerebral cortex is responsible for thinking and planning, will head to the depths of the brain hippocampus memory messages. Rose Aroma activities to stimulate the cerebral cortex, and enhance it to the hippocampus signals, thereby strengthening the people’s memory.
