Often referred to as the ‘elixir of life’ for its fundamental planetary functions, water can play an equally vital role in helping to shape our mental and emotional wellbeing.

 

Emerging research suggests that spending time in or near blue space environments can provide restorative benefits similar, and in some cases stronger than, those linked with other outdoor settings, e.g. green spaces (1, 2). You can think of it a bit like exercise. Just as cardio and strength training both aim to improve overall fitness, but via varying methods and with different aesthetic results – the specific type of outdoor environment has also been shown to have varying benefit in regards to our individual  wellbeing.

​

​One study comparing group walks through various urban and natural settings found that those who exercised in blue spaces reported higher self-esteem and improved mood compared to groups walking through wooded or farmland areas. Similarly, people living closer to the ocean tended to experience better overall physical and psychological health than those further inland, with beach and river environments consistently linked to greater contentment and reduced negative thinking (3).​

​

These findings support the Blue Mind Theory, popularised by marine biologist Dr. Wallace J. Nichols, which draws an evolutionary link between water and mental wellbeing. In essence, exposure to blue space can help to invoke a more meditative state of mind that stimulates the release of dopamine and serotonin, whilst lowering cortisol (4).

By improving cognitive function and helping to situate people more harmoniously within their surrounding environment, blue spaces positively contribute to our personal wellbeing and facilitate deeper and more meaningful place-based connections.
