There's something strangely calming about hearing the sound of rain.

This time, we will introduce the charm of the sound of rain, which gently soothes the anxiety and stress that tend to build up in our daily lives.

Please also take a look at our recommended audio sources.

Rainy days are the perfect time to relax

Many people may have the impression that rain makes them feel gloomy, but if you stay inside and listen to the sound of the rain without going outside, don't you feel a sense of relief and calm?

Yes, the sound of rain has a relaxing effect on people, and one theory is that on rainy days, the negative ions in the air increase, making people feel calm and relaxed.

This time, we will unravel the secret of the healing power that the sound of rain gives us, and also introduce some recommended sound sources that can help you relieve stress with the sound of rain even on days when it is not raining.

The sound of rain contains high frequencies

Why does the sound of rain have such a calming effect on our souls?
One of the secrets lies in the high frequency components contained in the sound of rain.

It depends on how the rain is falling, but generally the sound of rain sounds more like a whooshing white noise rather than the sound of individual drops.

White noise is created by mixing all frequencies equally, including very high frequencies.

This high frequency component is known to activate brain function, improve blood flow, and relax the entire body.

The surprising relationship between stress and the sound of rain

When a person feels stress, the balance of the autonomic nervous system is disrupted, and the sympathetic nervous system becomes active, switching on "fight mode" to prepare for external stimuli.

This causes blood vessels to constrict, blood pressure to rise, and blood circulation to become poor.

As we have seen, blood circulation and stress are inextricably linked, and as we mentioned earlier, the sound of rain, which is rich in high-frequency components, has the effect of promoting blood circulation.

In other words, if the sound of rain helps blood to flow normally to every corner of the body, it can ultimately help relieve stress.

The sound of rain has "1/f fluctuation"

Furthermore, another reason why we find the sound of rain so relaxing is due to "1/f fluctuation."

"1/f fluctuation" refers to the rhythmic fluctuation that natural sounds have , and "1/f fluctuation" is hidden everywhere within our human bodies.

For example, the fluctuations in the sound of rain resonate just right with the rhythm of our heartbeat and breathing, and this is why we can feel a sense of security and comfort from the sound of rain.

Great for changing your mood or cooling down

The sound of rain is the perfect healing music when you are feeling very anxious or when your blood pressure is rising due to anger.

In addition to the high frequency components and "1/f fluctuations" we introduced this time, rain = water simply has the image of washing away dirt, so when hearing the sound of rain, many people unconsciously recall this image, and feel refreshed when they are feeling uneasy.

When you're feeling irritated or sad and want to calm your mind, try listening to the sound of rain and relax.
