The relaxing sound
It’s not just smelling and breathing in rain that can make us feel good, though; it’s hearing it too, which is why you often find rain tracks on sound machines. A steady rain can reduce cortisol levels, inducing a sense of calm, as well as drowning out disruptive noises.
“Water sounds have been associated with activation of the parasympathetic nervous system, which is the branch of the nervous system involved in relaxation and recovery,” says Amy Sarow, a clinical audiologist who works in outpatient care in Southfield, Michigan in the US. “When this system is activated, we may see physiological effects such as lower heart rate [and] reduced stress responses.”
A recent study found the sound of rain was most effective within the 40 to 50 decibel range (equivalent to a soft, gentle rainfall), lowering stress levels up to 65%. Heavy rain, which falls into the even lower brown noise frequency, can feel more grounding and immersive, Sarow says, and drown out disruptive sounds to help promote sleep.
Both levels can be calming; Sarow says it often comes down to personal preference. “If someone intentionally listens to these sounds as part of a relaxation routine, the experience can begin to resemble mindfulness or meditation practices, where the sound serves as an anchor for attention and relaxation.”
While my rainstorm didn’t exactly put me in a zen state, it did leave me feeling better and more connected to the present moment. Now, every time there’s a downpour, I try to spend a little more time immersed in it. When you next see rain in the forecast, consider tuning into the experience too. You might be pleasantly surprised.
