The "Blue Mind" theory: Is it true that the sea is beneficial for human health?

The world grounds itself, the noise and chatter fade away, and only the crashing waves evoke admiration. However, ocean water is not merely a meditative element but also a source of beneficial properties for humans.

Sea water contains over 70 different minerals, including sodium, magnesium, iodine, and potassium. These can be absorbed through the pores and capillaries of the human body, ensuring the proper functioning of the organism. For instance, iodine plays a crucial role in thyroid function, while magnesium enhances sleep.

Sea air, saturated with salts and iodine, positively impacts the respiratory system. If you spend a month near the coast, you will likely forget what a runny nose feels like.

Austrian researchers conducted a survey of over 15,000 people from 14 European countries and Australia, asking them to evaluate the sea's impact on their health. The results of the study indicated that a significant portion of respondents noticed favorable changes after relocating or regularly visiting the sea.

Saltwater possesses antiseptic properties, making it extremely beneficial for the skin. It helps prevent possible infections, heals wounds, and improves microcirculation.

If you have acne or dermatitis, the sea can be a great ally in combating imperfections, but if you have dry skin, it’s best to avoid saltwater. In such cases, it will only draw out moisture, leading to irritation and dehydration.

The sea breeze, sunsets, and the sounds of waves are the perfect remedy for relaxation and stress reduction. This is supported by the theory of "blue mind." Dr. Nichols popularized this theory in 2014, describing the concept in his book "Blue Mind." It suggests that water increases the levels of neurotransmitters—serotonin and dopamine—thereby reducing stress hormones and boosting mood. It may seem like a simple wash, but it also offers a meditation experience.

Life on Earth began in the oceans. Besides being an essential source of nutrients and resources such as salt, seafood, and oil, the sea is our biological point of origin. Human tears and sweat have a salty composition, and the elements of the sea resonate with human bodies. This is all about biophilia—the innate desire of humans to maintain a connection with nature. Whether it’s walking on sand, diving beneath the waves, or simply observing, the sea allows us to set our minds aside and feel free.

People with disabilities or injuries may face challenges moving on land, which is not the case in the sea. In the water, everyone can experience freedom of movement and relaxation—both physically and mentally. For this reason, activities such as water sports can enhance psychological well-being. There are numerous events that help connect with the sea and feel its "comfort": from boating and diving to yoga therapy on a surfboard.

The sea not only brings physical and emotional well-being but also allows individuals to experience freedom and a connection with their environment.
