What would happen to your body after almost 55 hours swimming through the Baltic Sea without sleep? One Polish athlete has now given scientists a rare chance to find out, after an extraordinary request was made following his latest challenge. Bartłomiej Kubkowski had spent more than two days in open water during his attempt to swim from Sweden to Poland. The request came after he finally reached the Polish coast, following a journey of more than 160 kilometres.

Doctors asked if they could freeze samples of his blood for scientific research, Kubkowski agreed. The unusual request followed a feat that pushed him through exhaustion, sleep deprivation, cold water and difficult conditions. He completed the crossing on his fifth attempt, becoming the first person to swim from Sweden to Poland across the Baltic Sea. 

A fifth attempt finally succeeds

Kubkowski set off from Kåseberga in southern Sweden and reached Dziwnów on Poland’s Baltic coast. The journey covered just over 160 kilometres and took around 55 hours. Reports put his completion time at approximately 55 hours and 10 minutes. 

He remained in the water throughout the crossing, a support boat accompanied him, but he was not allowed to touch it. Food and drinks could be provided from the boat, meaning he had to keep swimming rather than climbing aboard to rest. He also went without sleep during the crossing. 

The achievement came after four previous attempts over five years. His previous effort ended when he was only around 11 kilometres from the Polish coast. Exhaustion and worsening conditions forced him to stop before reaching land. This time, he made it all the way to Dziwnów. 

His body became the next question

After the swim, medical staff carried out tests on Kubkowski, the results prompted the unusual request to preserve his blood for research. The samples could give scientists an opportunity to examine the physical effects of an endurance effort lasting more than two days. Kubkowski’s experience is particularly unusual because the crossing combined prolonged physical exertion with a lack of sleep and exposure to open water.

According to reports, the head doctor told Kubkowski that his blood results resembled those of someone who had just completed a marathon. That comparison came after a swim roughly four times the distance of a standard marathon, performed continuously through the Baltic. The samples will now be frozen rather than simply discarded after routine medical testing, allowing them to be used for further scientific work.

The final kilometres were the hardest

Getting to the Polish coast was not simply a matter of continuing at the same pace until the finish. Kubkowski said that around 11 kilometres from the end, he began losing consciousness and became unsure of where he was. A change in the weather added another difficulty during the final part of the crossing.

After spending more than two days awake and swimming, he still had to maintain enough concentration and strength to complete the remaining distance. He eventually reached the beach at Dziwnów, where supporters were waiting. The finish marked the end of a challenge that had occupied him for years.

The swim also raised money

Kubkowski’s Baltic challenge was linked to a fundraising campaign for Cancer Fighters, a Polish foundation supporting children with cancer. The campaign had raised more than one million Polish złoty by the time of the latest reporting.  That means the crossing was not solely a personal sporting challenge. Money was being raised for children receiving cancer treatment while Kubkowski attempted a route that nobody had previously completed in the same way.

Now the achievement has another potential legacy. The frozen blood samples could allow researchers to study what happens inside the body after an extreme endurance effort lasting almost 55 hours. Kubkowski set out to conquer the Baltic Sea after four failed attempts, He succeeded on the fifth.  But after 160 kilometres in the water, the most unusual part of the story may only just be beginning, because scientists now want to see what his body went through.

Imagine arriving in Spain for a long-awaited holiday, checking into your accommodation and closing the door behind you, expecting nothing but privacy, comfort and a few days away from everyday life. Now imagine that sense of security disappearing so quickly that you decide you cannot stay there.

That is the situation British couple Donna and Raymond Nunn found themselves in during a trip to Madrid to celebrate their 39th wedding anniversary. The couple had travelled to the Spanish capital for a bucket-list break they had wanted to take for years. Instead, their Airbnb stay ended with them leaving the city after discovering something inside the apartment that left them frightened to remain there.

Camera found pointing at the bed

The couple arrived at the apartment in Madrid’s Lavapiés neighbourhood on August 3. When they entered, they noticed what appeared to be a camera in the living room facing towards the front door. There was no flashing light, so they assumed it was a security device that was switched off. The following day, Donna, 62, went sightseeing while Raymond, 87, remained at the apartment because he is less mobile.

That was when he noticed another device, a camera in the bedroom had a green light flashing and was positioned facing directly towards the bed. Donna said that the camera was around four inches long and tucked into a corner of the room. She said they were extremely frightened when they realised what they had found as they had already slept in the bed the night before discovering it.

The couple contacted Airbnb on August 4 and were advised to leave the apartment immediately. However, by then it was around 08:00pm, leaving them with nowhere else to go that night. They eventually found another apartment around two hours south of Madrid and left the Airbnb on August 5, just two days after arriving. 

Their Madrid anniversary was cut short

The discovery meant the couple could not continue their planned trip around the Spanish capital. Donna said they had booked the accommodation in March and had expected to spend their anniversary exploring Madrid. Instead, they had to arrange alternative accommodation and abandon part of their sightseeing plans.

The couple, who originally come from Britain and moved to Spain in 1999, had specifically chosen Madrid for a trip they had wanted to make for years. The experience has left them unwilling to return to the capital, according to Donna.

For British visitors planning a Spanish city break, the unsettling part of the story is not simply that a camera was found. It is where the device was positioned. A bedroom is where holidaymakers expect to be able to sleep, change clothes and relax without being watched.

Airbnb removes the property

Airbnb has since removed the apartment listing from its platform and issued the couple with a full refund covering their original stay and the cost of rebooking elsewhere. The company has also suspended the listing while it investigates what happened as Airbnb’s rules leave little ambiguity over indoor cameras.

The company banned security cameras and recording devices inside its rental properties worldwide from April 30, 2024. The prohibition applies regardless of where inside the property the device is located and even if the camera is switched off or disconnected. Hidden cameras are specifically prohibited.  That means the device discovered in the Madrid bedroom would not be permitted under Airbnb’s current policy. Airbnb said violations can lead to listings and users being removed from the platform, and confirmed that it was investigating the Nunns’ case. 

What happened to the camera?

The discovery does not, by itself, establish whether anyone watched the couple or whether footage was recorded, stored or accessed. Those questions have not been answered in the reports about the incident. Donna said the camera had not shown a flashing light when they first arrived, but a green light appeared when Raymond noticed it the following day. 

She believed this suggested the device could potentially be switched on remotely, although that has not been independently established. Raymond decided to turned it around and leave it facing the wall after finding it. The couple then contacted Airbnb rather than continuing to stay in the property.

A warning for holidaymakers in Spain

When an incident that invades your privacy occurs it leaves other feeling particularly vulnerable and uncomfortable when booking private accommodations because guests often choose an apartment precisely because it offers the feeling of having a home of their own while abroad. Airbnb’s rules give guests a clear expectation: there should be no indoor security cameras monitoring them inside a property. 

If a holidaymaker discovers a suspected hidden camera, documenting what they have found and reporting it to the accommodation platform is important. If they believe a crime may have taken place, they can also contact the police.

The Nunns’ Madrid trip was meant to mark nearly four decades of marriage. Instead, after only two nights, they were packing their belongings and searching for somewhere else to sleep. They had travelled to Madrid expecting privacy behind the door of their holiday rental.They found the complete opposite.

A nonprofit organisation based in Murcia, Bomberos por Bomberos (Firefighters for Firefighters), has launched a critical humanitarian operation in Venezuela, delivering safe drinking water to populations severely impacted by the devastating recent earthquakes. As the organisation’s first international mission, the dedicated team has successfully completed complex technical installations to link a water well to a specialised purification unit located at the Caribe fire station in the Venezuelan city of La Guaira.

Local nonprofit’s first international mission delivers vital water supplies

This water treatment plant, a compact, high-capacity unit funded by the Universidad Católica San Antonio de Murcia (UCAM), can process up to 3,000 litres of clean drinking water every hour. The team constructed PVC pipelines to carry unpurified water from the well directly into the filtration system and out to an accessible distribution hub.

Bomberos por Bomberos is also coordinating tanker trucks equipped with large holding tanks to transport clean water directly into camps and remote settlements, where vulnerable local people are currently taking shelter.

Dedicated mobile distribution teams tackling a growing health crisis

Access to uncontaminated drinking water across the regions affected by the earthquakes has become critically scarce. Humanitarian workers warn that the deficit will worsen as other relief organisations phase out bottled water distributions in temporary camps. Without access to safe supplies, many desperate residents have turned to untreated well water, sparking widespread gastrointestinal illnesses and health complications.

Community awareness drives demand at local fire station

Local creators and Venezuelan social media channels have actively spread news about the new purification plant, driving a steady increase in daily demand at the Caribe fire station. With this effort, Bomberos por Bomberos continues to expand its logistics footprint to keep pace with the growing need for clean, fresh water.

Working tirelessly to provide water for displaced people, the Murcian firefighters are playing an essential role in stabilising public health and supporting vulnerable families through this devastating crisis. It is just one of the ways Murcian emergency responders and nonprofit organisations are working to spread humanitarian aid in light of the earthquake disaster in Venezuela.
