What is a lagoon?

A lagoon is a body of water that is smaller and shallower than a lake, located in a depression in the ground. It can form naturally, through the accumulation of rainwater, groundwater or meltwater, or artificially, as part of agricultural, recreational or landscaping projects.

Unlike a lake, a natural lagoon usually has a smaller volume of water and is often shallower, allowing light to penetrate easily to the bottom, which encourages the growth of aquatic plants. They can be permanent or temporary (drying up in times of drought), and their biodiversity is significant, as they provide a habitat for birds, fish, amphibians and insects.

What types of lagoons exist today?

Natural lagoons: a living and therapeutic ecosystem

A natural lagoon is a body of water that is smaller and shallower than a lake. They are usually connected to groundwater or rivers and often form habitats rich in biodiversity. Their peaceful conditions and natural surroundings make them ideal places for contemplation, relaxing swims or reconnecting with oneself.

These lagoons often contain minerals, algae and temperatures that vary depending on their location, which directly influences their health benefits.

Artificial lagoons: design, functionality and sustainability

Artificial lagoons recreate the conditions of a natural lagoon, but with a controlled design, water treatment and aesthetics designed for human well-being. They are integrated into gardens, hotels or resorts as unique aquatic spaces, combining technology, beauty and comfort in a multifunctional space.

Unlike a swimming pool, an artificial lagoon can be surrounded by vegetation, have an organic shape and be designed for multiple uses: recreational swimming, contemplation, boating or water sports.

Key differences between lakes and lagoons

Although they are often confused, there are clear differences between lakes and lagoons:

• Size: lakes are usually larger and deeper.
• Origin: lakes usually have greater hydrographic connectivity; lagoons can be formed by simpler coastal or geological phenomena.●      Ecosystem: lagoons have a more delicate balance, making them more sensitive but also more welcoming to humans.
• Ecosystem: lagoons have a more delicate balance, making them more sensitive but also more welcoming to humans.

Lagoons: wellbeing and health in a single aquatic space

Few experiences are as revitalising as immersing yourself in a lagoon. Whether surrounded by nature or designed for comfort, these bodies of water invite calm, connection and balance. Today, more than ever, lagoons represent an attractive alternative within the hospitality universe: aesthetic, sustainable and deeply recreational spaces.

Benefits of bathing in lagoons for your health and mind

Bathing in a lagoon is not just a pleasant experience. Recent studies on so-called ‘blue spaces’ show that contact with bodies of water reduces stress, improves mood and has physiological benefits.

Deep relaxation and stress reduction

The presence of water, combined with a natural environment or an immersive design, stimulates the release of endorphins and serotonin. Immersing yourself in a lagoon can induce a state of calm that helps you disconnect from your routine and reconnect with nature.

Stimulation of circulation and the immune system

The thermal contrast, contact with mineralised water or the simple act of floating help to activate blood circulation. In cold lagoons, the body responds by stimulating the immune system and reducing inflammation.

Dermatological and muscular benefits

Many bathing lagoons, especially natural ones rich in minerals, have beneficial effects on the skin: they help balance pH, reduce tissue inflammation and alleviate conditions such as eczema and psoriasis.

In addition, the environment free of harsh chlorine and chemicals offers a gentler experience for sensitive skin.

Connection with the environment and aquatic mindfulness

Bathing in a lagoon invites you to a state of mindfulness. The stillness of the water, the gentle movements, the silence that surrounds you… All of this facilitates a natural mindfulness practice that has positive effects on mental and emotional health.

Lagoons for bathing: how, where and what to bear in mind

Not all lagoons are suitable for bathing, but more and more spaces — natural or artificial — are being prepared to offer this experience safely.

Water safety and maintenance

It is important to ensure that the lagoon is well maintained. Artificial lagoons have efficient and sustainable treatment systems. Natural lagoons must meet health and biological control criteria to be safe.

Recommendations for choosing the ideal environment

• Look for peaceful environments that are integrated with nature.
• Avoid bathing in stagnant or still water.
• Opt for spaces designed for well-being, not just for swimming

Lagoons as a transformative experience in hotels and resorts

The presence of a lagoon in a hotel can completely transform the perception of the environment. Not only does it add aesthetic value, but it also generates a positive emotional effect on guests. Some clear advantages are:

• Increased differentiation from the competition
• Perception of higher category or exclusivity
• Longer time spent in common areas
• Boost to surrounding services and activities
• Harmonious integration with gardens, dining areas or terraces

These types of solutions make much more sense in large resorts or tourist complexes, where the available space allows for the design of generously sized lagoons with a variety of functional uses.
