Sea swimming in Cornwall – Benefits of cold water swimming

When we’re out on our beach cleans and recovery missions along the wild Cornish coastline –  we are often finding more than sea birds shivering in the icy thaw of morning and the brightly coloured shards and tangled nests of plastic we came for. Increasingly its brave fellow sea swimmers bracing the ice cold waters of the sea in the morning – as the past turbulent years has inspired lots of people to take up our favourite outdoor activity here in Cornwall – wild sea swimming. 

In this article we’re going to go through the what, why and where people are wild swimming near me – and how people and communities gain value from our sea as a ‘blue space’ for wellbeing, and how we work to protect it.

I must admit to us in Cornwall when we first heard of wild swimming we didn’t understand what was wild about it – traditional pools are so rare and sea swimming is such a norm (from traditions of it all year from summer dips to Christmas and New Years plunges.)

Wild swimming as it turned out is the act of swimming in the sea – or freshwater – in a place where nature is all around you. In Cornwall this is most easily off beaches, but can be done in rivers, quarries and tidal pools. With one of the longest coastlines and over 300 beaches in Cornwall you are spoiled for choice when choosing a wild swimming spot nearby.

Why Wild Swim: the Benefits of Cold Water for the MInd

Since the pandemic broke our habitual behaviours and upsetting our status quo in the most dramatic way, many have recalibrated and reorientated their priorities to spend more time on the things that bring them happiness – including the primal joy of simply being in nature. Sea swimming as one of the most accessible and effective ways to intensely experience natural extremes has increasingly been lauded as a mental health cure – but is it just another fad distracting from proven chemical and behavioural treatments – what is the scientific evidence?

Studies in recent years have started to show the effectiveness of cold water swimming in the fight against depression – with case reports on cold water swimming published in the most respected scientific papers of the British Medical Journal showing that cold water emersion may be an effective treatment for depression. Whilst this research is in the initial stages, there is still plenty of evidence to show how going for a cold water swim can help us lead healthier and happier lives.

Sea Swimming's Dopamine Boosting Power

Cold water swimming and even cold showers can boosts dopamine levels – releasing of endorphins.

Biophillia - Natures Highs

Biophilla – ‘the joy of being outdoors’ and connecting with nature has a proven, positive impact on mental wellbeing. Research shows that heading out into green and/or blue spaces can help make us feel better. This also helps to combat the effects of Seasonal Affective Disorder.

Being in the Moment through a Wild Swim

Living with depression, anxiety & PTSD can cause us to struggle with being in the moment – caught in a mental entanglement in our own minds . The shock of cold water, combined with being outside in nature, forces us to feel the moment and rebuild our connection between body and mind. 

Controlling Fear & Combating Anxiety

Conquering the resistance to entering cold water builds up our mental resilience – teaching our own mind their ability to control themselves – building our confidence and boosting self worth.

building community & keeping fit

By sea swimming with people we know and don’t as part of a group lets us grow and bond – building the social relationships we humans thrive on and combating the isolation of modernity whilst keeping fit and healthy. Fitness is often hard to maintain – but can have a huge positive impact on both our physical and mental health. Swimming is an excellent form of exercise and can help lower blood pressure, increase immunity and is considered a low-impact exercise making it more joint friendly for injured and elderly. In our experience its the 80 and even 90 year olds who make the bravest swimmers when the sea is flat and at its coldest in winter!

Inspired to Swim: Safety First

Before deciding to immerse yourself in icy water and give yourself a shock make sure it is safe. Going into cold water can be a shock to the system all year round. 

Got health conditions – check with your GP first – heart attacks & strokes can all happen in the water and can result in drowning. Swim within your limits – learn about swell, know water and air temperatures, undercurrents, tides, lay of the rocks underwater. 

Wear the right kit. Only swim where it’s safe; where you can enter and exit the water easily and there is someone to see you if you get into difficulties. Don’t rush – get cold and warm again slowly, the cold isn’t as dangerous as the shock of changing temp too rapidly. 

Please read the RNLI advice:

Mainly however Good luck! Don’t give up after the first attempt. It will feel cold, that’s the point!
