The Quick Science
Mineral-rich seawater supports muscle relaxation, skin conditioning, and a calmer nervous system. Boreas puts you directly in the Red Sea, one of the saltiest and most mineral-dense seas on Earth. Request charter rates to build a wellness week around it.

What Makes the Red Sea Mineral-Rich.
The Red Sea is one of the saltiest seas on Earth. High evaporation, low rainfall, and no major rivers keep its mineral concentration far above the ocean average.
That density carries magnesium, calcium, and sodium chloride in higher concentration than most seas. This is the same mineral profile thalassotherapy is built around.
What Happens to Your Body in Salt-Dense Water.
Denser, salt-rich water increases natural buoyancy. Joints and muscles carry less load while you float or swim.
Magnesium exposure through skin is a core thalassotherapy principle, linked to muscle relaxation. Mineral seawater is also used in skin conditioning routines for its hydrating, mineral-dense qualities.
Open Water Calms the Brain.
Proximity to open water is linked to lower stress and steadier mood, a pattern researchers call Blue Mind.
The Blue Mind Effect — Water and the Brain.
Time on or near open water is associated with a calmer nervous system and reduced stress response. The sound of waves acts as steady background noise that quiets mental chatter.
An open horizon with no fixed point to focus on gives the eyes and mind a genuine rest. This is why open-water time is often followed by better sleep that night.
Supports muscle relaxation and recovery after activity.
Salt-dense water eases joint load while you float or swim.
Mineral exposure is a core principle of thalassotherapy.
Steady wave sound quiets rumination and aids focus.
Open water views are linked to a measurable calming response.
Time on open water is linked to improved sleep that night.
Who Notices the Difference Onboard.
Divers and swimmers feel the buoyancy difference immediately. Non-divers get the same mineral and Blue Mind benefits from the sundeck, spa, or a slow swim off the platform.
No activity is required to benefit. Sitting near open water for an hour carries much of the same calming effect.
Boarding is Saturday at Hurghada Marina or Port Ghalib. Choose a full charter for 3, 4, or 7 nights, or join a scheduled voyage instead.

LOGISTICS & EVERYTHING YOU NEED TO KNOW.
Every cruise offers the opportunity to actively contribute to reef protection, shark science, and local community support — your trip leaves something behind.
Coral health monitoring programme. Guests collect live reef data during snorkelling sessions — observations submitted directly to UQ’s global database.
Cooperation programme and shark log citizen science. Divers contribute species and behaviour observations to global shark population research.
Dive briefings include shark conservation education. Shark Angels materials available aboard — guests leave with a grounded understanding of Red Sea shark behaviour and status.
Active support of Red Sea local communities. Guests can join community meetings and cultural exchanges during port stops.
Ongoing partnerships with HEPCA, CDWS, and international marine science associations — reef mooring compliance, waste protocols, and diver education on every charter.
No anchoring on living reef. Single-use plastic eliminated from all catering. Marine awareness sessions on selected evenings — open to all guests aboard.
Questions on Mineral-Rich Water & Wellness
Is the Red Sea really more mineral-rich than other seas?
Yes. The Red Sea is one of the saltiest seas on Earth, with average salinity well above the world ocean average. High evaporation, low rainfall, and no major rivers feeding it keep magnesium, calcium, and sodium chloride concentrated in the water.
What is thalassotherapy, and does Boreas offer it?
Thalassotherapy is the use of seawater and its minerals for wellness — through swimming, bathing, or skin exposure. Boreas guests get this naturally through swim access, spa treatments, and open-water time built into the daily rhythm aboard.
What is the Blue Mind effect?
Blue Mind describes the calming neurological response linked to being on or near open water — steadier mood, reduced stress, and better sleep. It’s part of why time on the Boreas sundeck or open water feels restorative, not just relaxing.
Do I need to dive or swim to get any benefit?
No. Sitting near open water, listening to it, and viewing the open horizon carry much of the same calming effect. Diving and swimming add the mineral and buoyancy benefits, but neither is required to feel the difference.
What wellness facilities are onboard?
Boreas has a spa, massage and facials, a dedicated yoga zone, and a sea-view gym, alongside two jacuzzis, a sundeck, and a star deck. All are included as part of the charter, whether you join by full charter or a scheduled voyage.
Can this be booked as part of a shorter trip?
Yes. Boreas runs full private charters of 3, 4, or 7 nights, or a scheduled voyage guests can join by the cabin. The Dolphins & Dugongs retreat is one scheduled option built around open-water time.
