What is the Guinness World Record for the longest time spent underwater, and how did the person survive?

The Guinness World Record for the longest time spent underwater is 382 minutes and 22 seconds, achieved by Walid Gabr, an Egyptian diving instructor, on October 16, 2014. Gabr set the record by using a technique called 'saturation diving', which involves breathing a special mixture of gases while living in a pressurized environment underwater. During the attempt, Gabr had to withstand water temperature of 29 degrees Celsius, and he consumed over 12 liters of water.

The technique of saturation diving is commonly used in deep-sea exploration and oil rig operations, where divers can remain underwater for extended periods of time without suffering from decompression sickness. The divers spend several days in a pressurized environment on a diving vessel before descending to the desired depth. The process allows their bodies to become saturated with the gases required for breathing at the desired depth. After the dive, the divers spend several days decompressing before returning to the surface to avoid decompression sickness, which can be fatal if not treated properly.

Walid Gabr's world record is a testament to the human body's incredible ability to adapt and survive in extreme conditions. The record also highlights the advances made in diving technology, which have enabled humans to explore some of the deepest parts of the ocean.

The current Guinness World Record for the longest time spent underwater without breathing apparatus is 24 minutes and 37.36 seconds. It was set by Budimir Šobat of Croatia on March 27, 2021. Šobat achieved the record in Sisak, Croatia, in a controlled environment with medical professionals on hand. He used a variety of techniques to help him hold his breath for so long, including relaxation, meditation, and visualization. He also trained his body to use oxygen more efficiently.

Here are some of the techniques that Šobat used to help him hold his breath for so long:

• Relaxation: Šobat practiced relaxation techniques such as yoga and meditation. These techniques helped him to calm his mind and body, which made it easier for him to hold his breath.
• Meditation: Šobat also practiced meditation, which helped him to focus his mind and block out distractions. This was important because distractions can make it more difficult to hold your breath.
• Visualization: Šobat used visualization techniques to help him stay calm and focused underwater. He would visualize himself swimming in a calm, peaceful environment.
• Training: Šobat also trained his body to use oxygen more efficiently. He did this by doing exercises that increased his lung capacity and improved his cardiovascular health.

It is important to note that Šobat's record is an extreme example and should not be attempted by anyone without proper training and supervision. Holding your breath for too long can be dangerous and even fatal.
