What is ocean swimming?
Ocean swimming, also known as sea swimming or salt water swimming, is a distinct form of open water swimming that takes place in the openness of the ocean. Unlike pool swimming, it requires navigating natural environments, from the calm of the Atlantic Ocean to more turbulent waters.
One of the key aspects of ocean swimming is the encounters with marine life and the natural movement of the water, which can be both exhilarating and calming, but also hostile. The ocean's salt water provides additional buoyancy and offers skin health benefits, making it a popular choice for many outdoor swimming enthusiasts.

Cold Water Swimming
Cold water swimming is a form of ocean swimming that has gained popularity for its health benefits. Immersing yourself in cold ocean water can stimulate the parasympathetic nervous system, promoting relaxation and reducing stress. Submerging your body in cold water triggers the vagus nerve, part of the parasympathetic nervous system.
Immersion in cold water is a stressor, so how can it also be a stress reliever, you ask. Let's find out.
Putting your body in cold water steals your body heat, and can put you at risk for drowning, or cardiac events. How can it also be healthy? Scientists don't fully understand the complexity of the phenomenon, but there are some indicators of why it works.
Cold water swimming activates muscles by shivering and it increases blood flow. Some studies have shown that it causes changes in white blood cells that lead to anti-inflammatory benefits. A recent study has shown that regular cold-water swimming can boost the immune system and improve mental health. The science points to many benefits, but more research is needed.
Health Benefits of Ocean Swimming
Whether you are swimming in the warmer waters of the Atlantic Ocean or braving colder climates, the experience of being surrounded by the natural environment and the vastness of the ocean offers a sense of freedom and connection that is hard to replicate in any other setting.
Physical Health Benefits
1. Cardiovascular Fitness
Ocean swimming is a fantastic form of exercise that improves cardiovascular fitness. The resistance provided by the moving water helps increase heart rate and enhance blood flow. You're engaging your heart in a way that land-based physical fitness activities or pool swimming doesn't do. It's a great way to stay active and support heart function and blood circulation.
2. Muscle Strength and Tone
The natural movement of the water requires more effort, making muscles more active and building muscle strength and tone. Ocean swimming remains a powerful workout for the entire body, even if you're not swimming any significant distance. Even simply playing in the waves requires muscle contraction to steady yourself beyond what non-moving water would, like in a pool.
3. Weight Loss and Metabolism Boost
Swimming in the ocean burns calories and boosts metabolism, aiding in weight loss. In fact, ocean swimming burns more calories than pool swimming, due to water movement, and lower temperatures. Doing it regularly is a great compliment to healthy eating and high quality sleep.
4. Improved Flexibility
Swimming in general supports flexibility due to the need for body movement that is unlike typical land-based exercise. Sea swimming adds the extra resistance of the water making it a great, low-impact way to expand flexibility. It's gentle on the joints and can allow for low-gravity flexibility training beyond what you could do on land. Some ocean swimmers report significant reduction of muscle aches and muscle fatigue.
5. Enhanced Immune System
Cold water swimming stimulates the parasympathetic nervous system and can boost the immune system. Some studies show that coldwater swimming boosts white blood cell count, which in turn helps immunity. Ocean swimmers report fewer and milder infections, according to one study.
6. Better Sleep
To put it plainly, ocean swimming can wear you out! Research shows ocean swimming leads to better sleep, due to changes in metabolism and release of feel-good hormones. This study shows that sea swimmers reported better sleep quality and overall health.
Mental Health Benefits
7. Stress Reduction
Overwhelming evidence exists for aquatic exercise and improved mental health. Ocean swimming, as compared to a swimming pool, had the added quality of being immersed in nature, and a view of beautiful coastlines. The calming effect of the ocean, the rhythmic water movement, and the physical exertion help reduce stress. This relaxing, meditative state is beneficial for mental health, calmness, feeling at one with nature and the connection to the physical world.
8. Improved Mood
During ocean swimming your body releases endorphins, improving mood and combating symptoms of depression. The combination of physical exercise and natural environments enhances mental clarity.
It's also said that the ocean blue color can contribute to these positive feelings of peace and euphoria. In addition to improving mood, studies also show that ocean swimming reduces tension, anger, depression and anxiety. That alone is an immense benefit.
9. Reduces Menopause Symptoms
A study from University College London published in 2024 found that menopausal women who regularly swim in cold water reported significant improvements in anxiety and other symptoms. The study highlighted the mental health benefits, noting that nearly half of the participants experienced reduced anxiety levels from cold water swimming.
10. Increased Mindfulness
Swimming in the ocean promotes mindfulness and a sense of presence. The vastness of the ocean and the connection with nature encourage a focused and mindful state. Although we don't yet have a full picture of the impacts, anecdotal evidence exists showing improved mindfulness, which leads to more positive feelings and lower depression.
11. Boosted Creativity
Being in the natural environment of the ocean and engaging in physical activity can enhance creativity and problem-solving skills. A review of multiple studies found that open-water swimming in natural environments, such as the ocean, not only improves mental health but also boosts creativity.
The immersive experience of swimming in natural settings helps clear the mind and allows for enhanced creative thinking by reducing stress and encouraging a state of mental relaxation and flow.
12. Enhanced Cognitive Function
Regular physical exercise, like ocean swimming, is linked to improved cognitive function. The increased blood flow to the brain helps maintain mental clarity and sharpness. It stimulates chemicals that alleviate depression, which can open cognitive capacity for critical thinking. It also supports the formation of new neurons, which improve memory and learning.
Saltwater swimming is more than just a way to cool off; it's an immersive experience that connects you with great effects. From the soothing rhythm of the waves to the thrill of spotting marine life, every dip is a new adventure. Whether you're a seasoned swimmer or just dipping your toes, the ocean offers endless opportunities for enjoyment and relaxation. So next time you find yourself by the shore, take the plunge and let the sea work its magic on you.
Of note, we also found evidence that swimming in sea water can alter skin bacteria, making some people more susceptible to skin conditions and infections. People with open wounds or compromised immunity should exercise caution.
Also, swimmers new to cold water immersion should exercise caution when trying cold water immersion.
