    In recent years, stressed-out urbanites have been seeking refuge in green spaces for the proven positive impacts on physical and mental health, but the benefits of “blue space” — the sea and coastline, but also rivers, lakes, canals, waterfalls, even fountains — are less well publicized, yet the science has been consistent for at least a decade: being by water is good for body and mind.

“Many of the processes are exactly the same as with green space — with some added benefits, ” says Dr Mathew White, a senior lecturer at the University of Exeter.White says there are three established pathways by which the presence of water is positively related to health and happiness. First, there are the beneficial environmental factors, such as less polluted air and more sunlight. Second, people who live by water tend to be more physically active. Third — and this is where blue space seems to have an edge over other natural environments — water has a psychologically restorative effect. When you are sailing, surfing or swimming, says White, “you’re really in tune with natural forces there.” By being forced to concentrate on the qualities of the environment, we access a cognitive state honed over millennia. Water is, quite literally, immersive.

Catherine Kelly is a wellness practitioner who teaches classes in “mindfulness by the sea”. She says the sea has a meditative quality.

“To go to the sea is synonymous with letting go, ” says Kelly. “It could be lying on a beach or somebody handing you a cocktail. For somebody else, it could be a wild, empty coast. But there is this really human sense of: ‘Oh, look, there’s the sea’ — and the shoulders drop.”
