Relaxing Sound of Rain and Thunder

According to a study released in 2016, the sound of rain can provide positive energy for some people. This positive emotion arises because the smell of rain makes the sense of smell interact with beautiful memories of the past.
Experts say that the smell of rain is first processed by a brain structure associated with the sense of smell, namely the olfactory bulb. The olfactory bulb has direct connections to parts of the brain that are closely related to emotion and memory formation, namely the amygdala and hippocampus.
Thanks to this positive impact, the sound of rain is often used as filler in relaxation and meditation videos. The reason is, the sound of rain has a regular and predictable pattern. Then, this sound is processed by the brain as a sound that gives peace.
