The health benefits of salt water are something the whole of humanity can benefit from. That’s why we are on a mission to create one billion Torchbearers for Ocean Change – working together to restore and protect our blue planet’s healthy balance.
Whether you’re a diver or not, salt water gives us a natural healing superpower which enriches our lives — and the best part? There is no cost to this modality. There’s a science behind how salted water, which covers more than 68% of the Earth’s surface, can help each and every one of us. It’s also no coincidence that the human body is composed of a similar percentage of this precious fluid.
Have you ever wondered why you feel so much better at the beach or at sea (if you have your sea legs)? We have the scientific answers behind the health benefits of salt water, which prove that there is much more to it than just a mindset.
Scroll down to discover our favorite benefits of salt water.
1. Salt Water Rejuvenates You
Seawater contains magnesium, an essential mineral involved in hundreds of processes throughout the body. Although the primary benefits of time spent in the ocean likely come from a combination of movement, relaxation, fresh air, and nature exposure, many people report feeling calmer, more refreshed, and better rested after spending time by the sea.
2. Salt Water Improves Your Skin
The ocean is rich in minerals such as magnesium, potassium, zinc, and calcium. While research is still evolving, spending time in salt water may help support skin health for some people. Salt water can help cleanse the skin, remove excess oil, and may temporarily improve certain inflammatory skin conditions.
Swimming in the ocean also encourages gentle exfoliation and increases exposure to fresh air and sunlight, which can contribute to an overall feeling of healthy, refreshed skin. However, prolonged exposure to salt water can be drying, so it’s important to rinse off and moisturize afterward.
Fun fact: Did you know that seaweed can help fight against the signs of aging in our skin?
3. Salt Water Contains Essential Minerals
Seawater contains a variety of minerals, including magnesium, calcium, potassium, sodium, and trace elements that play important roles in human health. While our bodies primarily obtain these nutrients through food and water, spending time in the ocean exposes us to a mineral-rich environment that many people find invigorating and restorative.
4. Salt Water May Support Easier Breathing
Swimming, diving, or simply spending time by the ocean can leave many people feeling as though they can breathe more comfortably. Ocean air tends to be more humid than dry inland air, which can help keep the nose and upper airways moist. This may support normal mucus clearance and reduce irritation in the nose and throat.
Breaking waves also release tiny salt-containing droplets into the air. While the concentration is much lower than that used in medical saline treatments, these microscopic particles may contribute to the sensation of clearer nasal passages for some people.
Swimming and diving offer additional benefits by encouraging slow, controlled breathing and improving overall cardiovascular fitness. Together, these factors may help explain why so many people feel refreshed after spending time in and around the ocean.
5. Salt Water Helps Us Feel Connected
Many people report feeling calmer, more relaxed, and more energized after spending time at the beach. Researchers believe this may be related to a combination of factors, including exposure to natural environments, the sound of waves, physical activity, sunlight, and time away from everyday stressors. Some proponents of “grounding” suggest that direct contact with the Earth may contribute to these benefits, although the scientific evidence for this mechanism remains limited.
6. Salt Water Supports Overall Health
Salt and water are essential for life. In fact, the fluids that circulate throughout our bodies contain dissolved electrolytes such as sodium, potassium, calcium, and magnesium, which help regulate hydration, nerve signaling, and muscle function.
While spending time in the ocean has not been proven to boost immunity directly, ocean activities such as swimming, diving, and walking on the beach can support overall health by encouraging physical activity, reducing stress, and promoting well-being. These factors are known to play important roles in maintaining a healthy immune system.
7. Salt Water Can Be Calming
Spending time near the ocean can promote relaxation and a sense of well-being. Many people report feeling calmer after listening to waves, watching the movement of the water or simply spending time by the shore.
Researchers believe these effects may be related to a combination of factors, including exposure to nature, rhythmic sounds, gentle visual stimulation and a temporary break from everyday stressors. The sights and sounds of the ocean can encourage a state of relaxed attention that is similar to the focus cultivated during mindfulness practices.
Whether you prefer a quiet beach or the energy of crashing waves, time spent near the water may help reduce stress and promote a greater sense of calm.
The processing of both the visual and audible elements of water help you fall into a soft focus — the same kind of thing that happens during mindfulness or meditation practice.
8. Salt Water Experiences May Support Digestive Well-Being
The connection between the brain and digestive system is stronger than many people realize. Stress can influence appetite, digestion and bowel habits, while relaxation can have the opposite effect.
Many people find that time spent in salt water helps them unwind and disconnect from everyday stressors. Whether you’re swimming, snorkeling, or scuba diving, these activities combine movement, nature exposure, and relaxation in ways that may support overall digestive well-being.
While salt water itself is not a treatment for digestive conditions, spending time in and around the ocean can be part of a healthy lifestyle that supports both physical and mental well-being.
9. Salt Water Encourages Physical Activity
One often-overlooked benefit of spending time near the ocean is that it naturally encourages movement. Whether you’re swimming, snorkeling, paddleboarding, freediving or scuba diving, salt water creates opportunities to be active in ways that feel enjoyable rather than like exercise.
The buoyancy of salt water can also reduce stress on joints and make movement feel easier. For many people, being in the ocean provides a low-impact way to build strength, improve cardiovascular fitness and spend more time outdoors.
For divers, this benefit goes beyond physical activity. Exploring underwater environments often inspires a deeper connection with nature and a greater commitment to protecting our blue planet.
10. Blue Spaces Support Mental Wellbeing
Researchers have increasingly studied the relationship between “blue spaces”, environments near oceans, lakes and waterways, and mental wellbeing.
Spending time near water has been associated with reduced stress, improved mood and greater feelings of relaxation. Scientists believe this may be linked to a combination of factors, including natural sounds, visual stimulation, physical activity and opportunities for mindfulness.
Divers often describe the underwater world as one of the few places where they feel fully present. The steady rhythm of breathing, the sensation of weightlessness and the absence of everyday distractions can create a uniquely calming experience.
Whether you’re floating on the surface or exploring beneath it, the ocean offers a chance to slow down and reconnect with the natural world.
