EGYPT : The record-breaking Freedivers of Egypt

Masters of relaxation: The record-breaking freedivers of Egypt.

When the countdown began, Khaled Elgammal took one final, deep breath before descending without any breathing equipment into the ocean. One minute and 29 seconds later, still holding his breath, the Egyptian athlete had free-fallen to 102 metres (335 feet) – a national record.

But for it to count, he had to reach the surface again. He turned at the bottom of the line and began his ascent – focusing on deep relaxation and the feelings of the surrounding water. In all, he had held his breath for two minutes and 50 seconds.

Elgammal is Egypt’s deepest freediver, and his remarkable achievement set a new national record at the Sharm el-Sheikh competition in October 2023.

“When I came to the surface, it was bliss. It felt amazing,” Elgammal recalls.

Freedivers like Elgammal rely solely on the ability to hold their breath while diving underwater. Through training, these divers master relaxation to slow down their heart rate, allowing them to stay beneath the surface without breathing equipment for minutes at a time. Very deep dives like the one he did recently usually require divers to hold their breath for around three minutes at a time.

The practice of freediving can be traced back to traditional fishing in communities like Asia’s Bajau people, where coastal groups have used freediving to hunt underwater for 200 years. As a sport, freediving is now undergoing record growth, attracting people looking to connect with the ocean and better understand their body’s abilities.

As for Elgammal, he says he was captivated by the unique sensations of diving with a single breath.

“I always say that scuba diving is everything in slow motion; you’re moving slow, breathing slow, and the sound of the bubbles is hypnotising, so everything is in slow motion. Freediving is like you’ve paused… and are the only thing moving down there. So you give yourself the chance to sink within.”

The sport is now growing in popularity around the world. According to AIDA International rankings, 2,889 freedivers registered to compete in competitions in 2023, more than twice the number a decade earlier.

The freediving organisation told Al Jazeera that around 20,000 people have become certified freedivers in recent years. Scuba Schools International (SSI) has similarly seen a steady 10 percent annual rise in the number of people earning their first freediving certification.

Many of these certifications are awarded in Dahab, a bohemian enclave on Egypt’s Red Sea coastline which has become home to numerous freediving schools and elite instructors. Dahab featured a shoreline of palm trees and traditional Bedouin homes just a few decades ago. While still considered a small town today, it boasts a thriving beachfront of Egyptian and international restaurants and attracts a growing crowd from Cairo, Europe and Asia. A handful of luxury hotels have emerged but Dahab still maintains an authentic charm – with herds of goats freely roaming the streets.

It’s also one of the world’s best-known freediving hotspots due to its year-round water conditions and proximity to Egypt’s Blue Hole. Just 20 minutes away by car, the Blue Hole is a famous reef-lined sinkhole accessible from the shore.

Here, divers can descend to around 90 metres (295 feet) – almost the height of the Statue of Liberty.

A heightened state of self-awareness

But what has contributed to the rise of freediving?

The sport is linked to several mental and therapeutic benefits. A 2013 study by academics at ​​Atilim University in Turkey, found that freedivers tend to exhibit lower stress and anxiety levels than non-freedivers.

Carlos Diezel, the manager of Dahab Freedivers, a school that trains divers, explained that much of this is down to “breathwork”.

“The fact that we have to pay attention to our breath, our mind and relaxation when we go down teaches us awareness,” he says. “I believe that part of the problem, statistically speaking, for mental health issues is related to the lifestyle in modern society, that’s leading people to forget or block any kind of self-awareness.”

This heightened state of self-awareness is something that dedicated freedivers like Elgammal strive for. “I’m always aware now of what I’m feeling, what I’m sensing,” he says. “Freediving helped me to connect with myself.”

Freediving’s connection with nature and immersion in water may also contribute to its mental health benefits. Diezel says the most common reasons people sign up for freediving courses are a fascination with the ocean and learning more about themselves.

“They grasp this connection with themselves when you hold your breath and go deep,” he said, adding that students consider it “a ‘deep’ experience – sorry for the pun”.

Social media equally plays a role in bringing freediving to the forefront. Many freediving pictures allude to a sense of freedom, featuring divers among marine life and colourful reefs. The hashtag #freediving has amassed more than 3.5 million mentions on Instagram so far. “It’s getting a lot of attention as it’s quite photographic. Some videos are just mesmerising,” Diezel adds.

Diving safely

Within the existing freediving community, the sport’s surge in popularity brings added responsibility. Considered an “extreme sport”, freediving can be risky if safety protocols aren’t followed, or divers push themselves beyond their physical limits. They can experience oxygen deficiency symptoms like hypoxia and blackouts, as well as pressure-related risks like a ruptured eardrum, an example of a barotrauma.

Contrary to portrayals such as Netflix’s The Deepest Breath, divers losing consciousness – known as blackouts – are relatively uncommon, particularly in recreational diving at shallower depths.

Freedivers are also trained to rescue a fellow diver safely as part of their earliest training, learning to monitor each dive, spot signs of distress and how to react. Under the buddy system, which helps to ensure freedivers remain safe, divers never dive alone.

Tamsyn Signe is a professional freediver who champions safety whenever she enters the water. She has worked as a safety freediver in multiple competitions, and it’s her role to ensure the competing divers make it to the surface safely. Last year, she saved a diver’s life 30 metres (98 feet) underwater in a rare example of a deep rescue.

“As he got in front of me, the lights went out,” Signe recalls, describing the moment the ascending freediver just stopped moving after losing consciousness. At 30 metres below the surface, Signe was also holding her breath. However, she wasn’t thinking about the carbon dioxide building in her body – she had a job to do.

“Everything really slowed down,” she says. “I knew I was his best shot at being ok.” As she’s trained to do, Signe closed his airways with her hands and started finning (swimming up with flippers) with him toward the surface – a tricky job with the added weight of another diver. The competitor regained consciousness after reaching the surface, partly thanks to Signe’s quick thinking and supportive team. He would later reach out and thank her for saving his life.

Signe says the rescue changed her life too, making her more observant and prepared for unexpected risks, but it’s part of the job. Most freedivers believe that practising safety in freediving, such as never diving alone and being trained for rescue, is crucial to the sport’s survival.

But this is not just a tick-box exercise; safety also forges close bonds within the community. “When you go through an experience with people where you could potentially die, there’s some sort of connection that happens that is way deeper and intimate than normal. And those friendships do last a lifetime,” Signe adds.

Responsibilities beyond the breath-hold

Alongside valuing safety, Zahraa El-Husseiny, a freediving instructor and Egyptian national record holder, believes that protecting our oceans is also an important responsibility which comes with freediving. Many freedivers collect plastic they find floating in the water; others, like Diezel, stopped eating seafood after learning about the human impact of overfishing.

As Earth’s oceans face increasing pressures from pollution and global warming, those who rely on the sea will play a vital role in future conservation. First drawn to freediving because she was fascinated with marine life, El-Husseiny tries to teach others about respecting the ocean through her sport.

“We are very connected to the ocean, and we owe it to this to protect it. We know how essential it is to move freely underwater, so… we need to protect it,” she says.

For many, freediving offers a path for self-discovery and a deeper connection to the natural world. As a sport, it’s poised for continued growth in the future.

Freediving isn’t reserved for a select few either, and freediving communities are expanding in many coastal locations. “Everyone can learn how to hold their breath,” El-Husseiny adds.

“Everyone can learn how to enjoy the ocean and the peacefulness of diving. I would like people to know that this is something they can do, learn and progress in”, she says.

Passing on the love of this sport is something many freedivers take seriously. When Elgammal isn’t training for record-breaking dives, he’s working as an instructor and coach. He similarly urges those interested in the sport to “be curious”.

“Relax, enjoy, trust. Think about what you like and try to visualise that feeling.”

EGYPTIAN-BRITISH: Deena Rahman: Bahrain’s record-breaking trailblazer

Rahman was one of the first women to be paid to play football in Europe – and set a host of records!

  • Deena Rahman owns five Guinness World Records
  • She was one of the players who got contracts when Fulham became professional in 2000
  • Rahman represented Bahrain in 40 matches, and scored 23 goals

In 2000, almost a decade before the English Football Association awarded the first central contracts to women, Fulham Ladies, at the insistence of club chairman Mohamed Al-Fayed, turned fully professional. It was a watershed moment in the history of women’s football. One of the 16 players paid to play professional football, a first in Europe, was Deena Rahman.

Deena Rahman’s career has since become one of football’s enduring legacies. She has played for the England women’s age group teams, then Bahrain national team. A midfielder during her playing days, the 39-year-old now works to promote gender equality in football while also creating a host of world records. The former Fulham midfielder currently holds five Guinness World Records!

Born to an Egyptian father, Deena Rahman rose through Fulham’s youth ranks, then joined the Arsenal Academy. But she returned to Fulham, and became a member of the team which completed a treble of Premier League National Division, FA Cup and League Cup in 2003. The club became semi-professional soon enough, after three years.

At 15, Rahman made her England U-18 debut. She also represented the country of her birth in two UEFA Women’s Under-19 Championships. However, she retired as a Bahraini player, having scored 23 goals in 40 matches after making her debut in 2011. She is regarded as one of the greatest to have played for the Reds, the nickname for the team from the small Western Asian kingdom.

In her journey – from Fulham to Manama with a brief stoppage in Cairo – Deena Rahman has witnessed a whole gamut of human experience. As a prodigious talent in England, she was a regular at the all-conquering Fulham. But injury and the disbandment of the Cottagers in 2006 forced her to move to Egypt, where she played for Wadi Degla for a brief spell. Another injury sidelined her, and she was back in England.

Then Bahrain came calling, thanks to her association with Arsenal. In 2010, Rahman arrived in the Gulf to work as a coach at Arsenal Soccer School at Soccer City in Janabiya. After five years there, she and her husband Paul Shipwright established their own academy, Tekkers Academy.

Meanwhile, Rahman was also busy creating her own legacy. In 2017, she, along with 32 women from 20 countries, set the Guinness World Record for the highest game of football ever played. And the setting was 18,760 feet above sea level, atop Mount Kilimanjaro in Tanzania – the highest mountain in Africa.

The following year, Deena Rahman played her part in setting another Guinness World Record, this time for a game of football at the lowest point in the world, the Dead Sea in the Jordan Rift Valley, at 1,412 ft below sea level.

In 2019, Rahman clocked two more Guinness World Records by taking part in a match featuring 822 players during the biggest five-a-side game at Olympic Lyonnaise Training Academy in Meyzieu, Lyon. Then in an exhibition match on the sidelines of the 2019 FIFA Women’s World Cup in France, she got her fourth Guinness World Record as a part of the match with the most nationalities – 114 participants, representing 53 nationalities. In 2020, Rahman secured her fifth record by hammering 7,876 penalties in 24 hours at the Kick Off Academy in Saar.

LIBYAN Desert’s Yellow Glass: how we discovered the origin of these rare and mysterious shards

The Great Sand Sea Desert stretches over an area of 72,000km² linking Egypt and Libya. If you find yourself in a particular part of the desert in south-east Libya and south-western parts of Egypt, you’ll spot pieces of yellow glass scattered across the sandy landscape.

It was first described in a scientific paper in 1933 and is known as Libyan desert glass . Mineral collectors value it for its beauty, its relative rarity – and its mystery. A pendant found in Egyptian pharaoh Tutankhamun’s tomb contains a piece of the glass . Natural glasses are found elsewhere in the world; examples include moldavites from the Ries crater in Europe and tektites from the Ivory Coast. But none are as rich in silica as Libyan desert glass, nor are they found in such large lumps and quantities.

The origin of the glass has been the subject of debate among scientists for almost a century. Some suggested it might be from volcanoes on the moon. Others propose it’s the product of lightning strikes (“fulgurites” – glass that forms from fusion of sand and soil where they are hit by lightning). Other theories suggest it’s the result of sedimentary or hydrothermal processes; caused by a massive explosion of a meteor in the air; or that it came from a nearby meteorite crater .

Now, thanks to advanced microscopy technology, we believe we have the answer. Along with colleagues from universities and science centres in Germany, Egypt and Morocco, I have identified Libyan desert glass as originating from the impact of a meteorite on the Earth’s surface.

Space collisions are a primary process in the solar system, as planets and their natural satellites accreted via the asteroids and planet embryos (also called planetesimals) colliding with each other. These impacts helped our planet to assemble, too.

Under the microscope

In 1996 scientists determined that the glass was close to 29 million years old. A later study suggested the source material was composed of quartz grains, coated with mixed clay minerals and iron and titanium oxides.

This latter finding raised more questions, since the proposed age is older than the matching source material in the relevant area of the Great Sand Sea desert. To put it simply: those source materials didn’t exist in that location 29 million years ago.

For our recent study, a co-author obtained two pieces of the glass from a local who had collected them in the Al Jaouf region in south-eastern Libya.

We studied the samples with a state-of-the-art transmission electron microscopy (TEM) technique, which allows us to see tiny particles of material – 20,000 times smaller than the thickness of a paper sheet. Using this super-high magnification technique, we found small minerals in this glass: different types of zirconium oxide (ZrO₂).

Minerals are composed of chemical elements, atoms of which form regular three-dimensional packaging. Imagine putting eggs or soda bottles on the shelf of a supermarket: layers on top of layers to ensure the most efficient storage. Similarly, atoms assemble into a crystal lattice that is unique for each mineral. Minerals that have the same chemical composition but different atomic structure (different ways of atom packaging into the crystal lattice) are called polymorphs.

One polymorph of ZrO₂ that we observed in Libyan desert glass is called cubic zirconia – the kind seen in some jewellery as a synthetic replacement for diamonds. This mineral can only form at a high temperature between 2,250°C and 2,700°C.

Another polymorph of ZrO₂ that we observed was a very rare one called ortho-II or OII. It forms at very high pressure – about 130,000 atmospheres, a unit of pressure.

Such pressure and temperature conditions provided us with the proof for the meteorite impact origin of the glass. That’s because such conditions can only be obtained in the Earth’s crust by a meteorite impact or the explosion of an atomic bomb.

More mysteries to solve

If our finding is correct (and we believe it is), the parental crater – where the meteorite hit the Earth’s surface – should be somewhere nearby. The nearest known meteorite craters, named GP and Oasis, are 2km and 18km in diameter respectively, and quite far away from where the glass we tested was found. They are too far and too small to be considered the parental craters for such massive amounts of impact glass, all concentrated in one spot.

So, while we’ve solved part of the mystery, more questions remain. Where is the parental crater? How big is it – and where is it? Could it have been eroded, deformed or covered by sand? More investigations will be required, likely in the form of remote sensing studies coupled with geophysics.

EGYPT: 79 Cairo University Scholars among Best Scientists in Stanford University report

A total of 79 scientists from Cairo University are among a list of 160,000 scientists whose practical opinions are cited in various specializations with a (2 percent). 

President of Cairo University Dr. Mohamed Othman Elkhosht received a report on Stanford University’s announcement of a list of scientists whose practical opinions are cited in various specializations with a (2 percent), featuring about 160,000 scientists from 149 countries, based on the Scopus database, in 22 scientific specializations, and 176 sub-specialization for distinguished researchers.

Dr. Elkhosht announced that the Stanford list included a large number of Cairo University scientists, with a total of 79 scientists on the two lists, whether the total from 2011 to 2022, or the latest version 2023, as this year’s list included scientists from 11 colleges (an increase of 8% over the previous year).

Number of scholars featured from Cairo University in the report’s 2022 edition was 73 scholars, representing 9 of the university’s faculties, and compared to the number of 74 and 55 scholars during the previous years (2021 and 2020, respectively), Cairo University thus leads all Egyptian universities and research centers in all years from 2020 until now.

Dr. ElKhosht explained that the annual Stanford University report is an objective, external indicator of the progress of scientific research at Cairo University.

It is also a quantitative indicator for the university to identify the number of distinguished faculty members in research and a reflection of the university’s methodology, plan, applied practices, and the support that the university provides to its employees from the various colleges and institutes affiliated with it.

Dr. Mahmoud Al-Saeed, Vice President of the University for Postgraduate Studies and Research, pointed out that the report reflects the strengthening of the confidence of the international scientific and research community in our scientists in all fields and specializations, and that the results of the classification this year included two lists, the first of which is specific to the list of the total practical years 2011 – 2022 (with a total of 417 scientists), While the second included the list of last year, 2022, with a total of 817 scientists, adding that this year’s list (2023 edition) contained 926 Egyptian scientists, while last year’s list (2022 edition) included 680 Egyptian scientists from various universities and research centers, compared to 605 and 396 during the years 2021 and 2020, respectively.

Stanford University used the Scopus database of the international publisher Elsevier to extract various indicators in this list, including global scientific publishing, the number of citations, the H index, and co-authorship, all the way to the composite citation index.
