Coastal environments have been shown to improve our health, body and mind.
The benefits of “blue space” – the sea and coastline, but also rivers, lakes, canals, waterfalls, even fountains – are associated with many positive measures of physical and mental wellbeing, from higher levels of vitamin D to better social relations.
An extensive 2013 study on happiness in natural environments prompted 20,000 smartphone users to record their sense of wellbeing and their immediate environment at random intervals. Marine and coastal margins were found by some distance to be the happiest locations, with responses approximately six points higher than in a continuous urban environment.
There are three established pathways by which the presence of water is positively related to health, wellbeing and happiness. First, there are the beneficial environmental factors typical of aquatic environments, such as less polluted air and more sunlight. Second, people who live by water tend to be more physically active – not just with water sports, but walking and cycling.
Third – and this is where blue space seems to have an edge over other natural environments – water has a psychologically restorative effect. White says spending time in and around aquatic environments has consistently been shown to lead to significantly higher benefits, in inducing positive mood and reducing negative mood and stress, than green space does.
People of all socioeconomic groups go to the coast to spend quality time with friends and family. Dr Sian Rees, a marine scientist at the University of Plymouth, says the coastline is Britain’s “most socially levelling environment”, whereas forests tend to be accessed by high-income earners. “It’s not seen as being elite or a special place, it’s where we just go and have fun.
