The sea has always been a place of escape, contemplation, and rebirth. Today, however, we know that this ancestral relationship with water is moving beyond the realm of folklore and into that of scientific research. Living near, spending time in, or simply being near the blue waters does, in fact, appear to be associated with improved psychological well-being.
Scientific literature has long discussed the positive effects of natural spaces on mental health. While the debate has long focused primarily on parks and forests, attention is now rapidly shifting toward water-dominated environments. The study, coordinated by Richard S. Geary and colleagues for the UK’s National Institute for Health and Care Research, highlights how green and blue spaces can promote well-being through various mechanisms: stress reduction, psychological recovery, improved cognitive function, increased social interaction, and even mitigation of the effects of air and noise pollution. The authors themselves, however, urge caution: while the findings are promising, further studies are needed to define the cause-and-effect relationships more precisely.
It’s not enough to have the ocean right in front of you
In fact, research suggests that it is not just the presence of water that matters. The quality of these environments, their accessibility, perceived safety, and the frequency with which they are actually used all come into play. A run-down or hard-to-reach waterfront does not have the same impact as a well-maintained and accessible space. Similarly, mere geographical proximity does not guarantee benefits if people do not have a practical opportunity to visit those places.
This is an issue that touches on urban planning. Ensuring accessible blue and green spaces means addressing a key factor that also helps reduce social inequalities, given that the most vulnerable communities are often those with the least access to these natural environments.
When the Sea Becomes Part of Therapeutic Programs
Meanwhile, practice is outpacing research. As The Guardian reports, in the United Kingdom and other countries, there is a growing number of initiatives that use the ocean to support treatment programs for people with post-traumatic stress disorder, anxiety, depression, or addiction.
A prime example is the story of Dave Phillips, a former corporal in the British Army, who—after seeking help for post-traumatic stress disorder—found sailing, through the Turn to Starboard organization, to be a crucial part of his recovery journey. “The sea takes me away from the stress and tensions of life. It has the power to calm me,” he says.
According to Catherine Kelly, a geographer who has been studying the relationship between health and aquatic environments for years, water fosters a different state of mind than the one imposed by a daily life dominated by digital screens. “When we go into the water, our shoulders relax, and our eyes and faces soften. We begin to breathe more slowly,” she explains in an interview with the British newspaper.
A resource to be protected
The challenge, therefore, goes beyond individual well-being. If blue spaces represent an opportunity for public health, the consequences of their degradation become even more evident. Polluted rivers, concrete-covered coastlines, compromised lakes, and restricted access do not merely deplete ecosystems; they also limit the ability of millions of people to benefit from environments that research increasingly recognizes as vital to psychological well-being.
Water conservation, therefore, concerns biodiversity, the landscape, and environmental quality, but also people’s health. And this is one of the most concrete reasons why it’s worth defending blue spaces: not because they’re a miracle cure, but because they represent one of the natural infrastructures that can contribute—along with many others—to making communities healthier, more livable, and even more resilient.
