ArabiaWeather - Maybe you fooled someone one day, with the trick of sleeping with one eye. Here's the hard truth: Someone on this planet actually sleeps with one eye and half a brain.. Among all the creatures on Earth, cute dolphins are distinguished by their ability to sleep with only one eye, and the suspicious In fact, she may end her life if she sleeps with both eyes open!

Dolphins sleep with one eye!

Dolphins sleep in a unique way, as these sea creatures sleep with one eye, and part of their brain remains awake and their open eye allows them to monitor the environment and react to any potential threat, while the other side of their brain continues to sleep, and the opposite eye remains closed. After about two hours, the situation changes so that the side that was awake is at rest and the other side is completely asleep, causing the entire brain to rest.

Dolphins are mammals, and they share many characteristics with humans. Dolphins have a bony structure, are warm-blooded, and have a unique respiratory system that gives them the ability to remain underwater for long periods without needing to take in oxygen. Dolphins can stay underwater for up to about 30 minutes and more, which depends on their breathing system, which consists of two lungs. Thanks to this device, the dolphin can inhale and breathe air similar to human lungs.

Despite the biological similarities between humans and dolphins, there is a notable difference in the breathing process. While humans and other mammals have the ability to breathe involuntarily on Earth, dolphins must consciously decide on their breathing activity.

Dolphins have to be conscious to decide when to breathe, something that happens hundreds of times during their lives. A system of receptor cells in the dolphin's brain alerts it when it needs oxygen, allowing it to open an opening at the top of its head, a flap of skin that opens and closes to breathe and make sounds. This unique approach to dolphins' breathing reflects their constant need to ensure they get the oxygen necessary to survive.

Despite the great similarity between humans and dolphins, there appears to be a significant difference in the breathing process. It seems that dolphins need to constantly remain conscious to determine when they can breathe, otherwise they risk death. Simply put, she must remain alert to decide on the breathing process. Which simply means, “Staying alert means staying alive.” This poses a major challenge, as the human brain needs periods of unconsciousness to ensure it functions properly.

To understand how dolphins manage breathing and sleep, scientists have studied dolphins using electroencephalograms (EEGs), in which electrodes are placed on the head to measure electrical activity in the brain. The results showed that during the sleep cycle, one half of a dolphin's brain remains in a 'switched off' state while the other half remains 'active'. The researchers noted that dolphins remain in this state for approximately eight hours a day.

In terms of dolphin rest, the state they experience during sleep may be similar to the partial awareness we feel before we fall asleep, where we are on the verge of dozing off but still able to interact with our surroundings. Therefore, dolphins' sleep period may be considered a consciousness-like state that allows them to remain awake enough to interact with the environment if necessary.
