How long is the longest time a human can hold their breath ??

On average, a healthy young person can hold their breath for up to 3 minutes and can last longer if trained. However, because the amount of oxygen stored in the body is not very high, people may start to lose consciousness after a certain limit.

The cause of breathing is not the lack of oxygen, but the accumulation of carbon dioxide in the blood. When the pressure of carbon dioxide in the blood is high enough, the body's desire to breathe becomes very urgent. This is because the respiratory center in the brain is triggered by carbon dioxide, forcing the body to open its mouth for air.

By the pool, the children often gasped for air, each breathing was rapid and deep, for several minutes at a time, thinking that they were inhaling a lot of oxygen, but in fact they were expelling carbon dioxide from their bodies. Children may be able to stay underwater for an extra 30 seconds, but doing so is dangerous because they don't have any extra oxygen to supply. Because the partial pressure of oxygen in the brain is too low, it may cause brain dysfunction, so people start to choke on water or even drown in the pool.

The human body lacks strong receptors to sense the lack of oxygen in the body. In fact, the lack of oxygen causes temporary feelings of euphoria and excitement, which is one of the reasons why people get excited when they first visit a high mountain region. Before the invention of oxygen masks, pilots who were involved in early air combat were also affected by temporary euphoria.

At an altitude of more than 6,000 meters, the pilots became more and more excited as they flew through the dense anti-aircraft fire network and over the target, and then began to make mistakes in judgment, lose consciousness, and finally lead to a crash and death.

Hehe, in general. I remember that the highest record for underwater diving was about 7 minutes without ventilation. There's also water pressure and psychological effects.

Just found: Xinhua News Agency sent a very interesting news today: On April 26, Italian David Murini held his breath for 21 minutes and 29 seconds in a transparent water tank in Bahrain.

Breathing for 10 minutes will lead to suffocation and death.

Humans need to breathe oxygen to survive, and when we hold our breath, our bodies start running out of oxygen and accumulating carbon dioxide.

Over time, our bodies feel a lack of oxygen, which can lead to dizziness, coma, and eventual death.

In fact, according to scientific research, the longest human breath holding record is 22 minutes, and this extreme situation can only be done by highly trained and professional freedivers.

For the average person, holding their breath should be well below this range.

Therefore, please do not try to hold your blind breath beyond your limit to avoid endangering your life.

The length of time you hold your breath is related to your tolerance and health.

People with normal health can generally hold their breath for about 40 seconds to 1 minute, and some people can even hold their breath for 2-3 minutes.

However, holding your breath for long periods of time can lead to a rise in carbon dioxide levels in your blood and a lack of oxygen, which can lead to dangers such as suffocation, fainting, or death.

If you hold your breath in the water, the time is shorter, and it is easy to suffocate and drown.

Therefore, we should not try to hold our breath for a long time, especially in dangerous situations, and should always breathe fresh air to ensure our own safety.

The human body needs oxygen**, and if there is not enough oxygen for a long time, it will lead to hypoxia, suffocation, and eventually death.

If a person is in an enclosed and airtight environment, such as in a closed garage or underwater, it is easy to suffocate to death.

In addition, diseases such as the respiratory system and cardiovascular system can also lead to hypoxia, suffocation, and eventually death, so it is also important to be careful with people with related diseases.

The human body needs enough oxygen to survive and function properly, and prolonged lack of oxygen or being in an airtight environment can lead to serious consequences and even death.

Here's how to properly contact breath holding:

2.The time you hold your breath can start at 10 seconds and gradually increase to 30 seconds, 40 seconds, and so on. The duration of each breath-holding should be gradually increased until it can be held for 1 2 minutes.

3.During breath-holding, you can press your nostrils with your fingers to prevent inadvertent breathing.

4.When the breath-holding is over, slow down the breathing and take deep breaths to replenish the oxygen in the body.

5.Beginners should not hold their breath for too long to avoid dangerous situations such as suffocation.

When practicing breath-holding, pay attention to gradually increasing the time of breath-holding, and do it when it is safe to do so, paying attention to your body's reactions at all times to ensure your own safety. It is advisable to practice under the guidance of a professional.

Human breathing was first introduced in the Eastern Han Dynasty.

The first medical scientist to use artificial respiration to save people was Zhang Zhongjing, which was recorded in Zhang Zhongjing's book "Jin Kui Yaolu" "Miscellaneous Prescription Twenty-three" The method of "saving oneself from hanging":

Slowly untie it, do not intercept the rope, and lie down and down. One person stepped on his shoulders with his feet, and his hands were less and instructed him not to indulge in the strings; One person pressed his hand on his chest and counted it; One person rubs his arm and shin flexion and stretches. If it has been stiff, but gradually bent into the trap of the state pinned, and press its belly.

In such a cooking, the breath comes out of the mouth, Wang You's breathing eyes are open, and it is still intimidating to press it, and do not work hard, it must be a moment, you can less and cinnamon branch soup and porridge clear, contain it, so that the throat can be swallowed, and it will stop for a while, if you want to make the two people blow their ears with a tube, good, this method is the best, and all of them are alive.

This means that when encountering a patient who hanged himself, he should not cut the rope of hanging, but should first hold the patient, slowly untie the rope and put the patient in the quilt to keep warm. One puts both feet against the patient's shoulders, and one person presses both sides of the patient's chest with both hands, pressing up and down to relax; The other person holds the patient's upper limbs with his hands, bending and stretching, in conjunction with the person who is pressing on the chest.

This kind of first aid action requires a continuous meal, that is, about half an hour. You can feed the patient an appropriate amount of soup and porridge, and stop when you can swallow it gradually, if you can blow the patient's ears with a tube, the effect is better, this method is the best, there is no inactivity.

Holding your breath for 10 minutes can be extremely life-threatening and potentially fatal.

In general, the human body only survives for a few minutes without air** because our body needs oxygen to maintain normal physiological functions.

First, when we hold our breath, the amount of oxygen in our blood begins to decrease rapidly, and at the same time, carbon dioxide begins to accumulate. This can lead to abnormalities in the function of the heart and lungs, which can eventually lead to a lack of oxygen to the brain, fainting, and death.

Secondly, even if you have enough patience or mental strength to breathe deeply and fully before holding your breath, it is still not recommended to hold your breath for more than 10 minutes. Sleepiness is because during this process, the body's carbon dioxide levels rise dramatically, increasing the risk of choking and other dangerous conditions.

Science tells us that humans are oxygen-breathing animals, and their bodies need to breathe fresh air continuously to ensure normal metabolism and function. Therefore, holding your breath for 10 minutes is very dangerous or even fatal behavior and should not be attempted. If you have any questions or need training, you should do so under the guidance of a professional coach or doctor.

In conclusion, humans can only survive for a few minutes without oxygen**, and holding their breath for 10 minutes is a very dangerous and even fatal behavior. We should keep breathing normally and pay attention to the hygiene and health of the respiratory tract.
