How the sea reduces stress and heals the mind?

A new study published in the journal Health & Place confirms that living in coastal areas not only reduces stress levels but also contributes to overall mental well-being.

Scientists from the University of Exeter and Denmark's Aarhus University studied data from more than 25,000 people and found that proximity to the sea or ocean has a pronounced calming effect, comparable to a normal state of mental health.

The mechanisms behind this phenomenon are multifaceted. First, visual contact with the water surface, especially with its rhythmic waves, activates the parasympathetic nervous system, reducing levels of cortisol - the stress hormone. Second, sea sounds, such as the noise of waves, provide natural white noise that helps drown out distracting thoughts and improves sleep quality. Additionally, coastal air, rich in negative ions, helps improve mood and cognitive functions.

Researchers also note the social aspect: coastal zones often promote an active lifestyle, including walking, swimming, and communing with nature, which further reduces anxiety. "Living by the sea creates a unique environment where nature and humans interact harmoniously, supporting mental health," says the study's lead author, Dr. Lewis Elliott.

These findings emphasize the importance of preserving coastal ecosystems and access to them for public health. Scientists urge urban planners to consider proximity to water when designing new residential areas to make "sea therapy" accessible to all.
