As we all know, the role of the nose is to help breathing, inhale fresh oxygen and exhale carbon dioxide in the human body, which is called old and new. But you may not know another problem, that is, two nostrils correspond to two lobes, the left nostril corresponds to the left lung and the right nostril corresponds to the right lung. If one nostril is blocked, one lung has to compete with the other to exchange gas from the other nostril.
1, two nostrils can make breathing exercise more effective, reduce the resistance of breathing exercise, and thus promote human metabolism.
2. Breathing through two nostrils is also good for them to rest. Studies have shown that if you breathe through one nostril, you will feel tired for three hours, so the nose also has feelings, and they also need to rest.
3, breathing through two nostrils is good for sleep. If you lie on your side, keep a posture the same throughout your sleep. Because of gravity, one nostril is usually blocked, which affects your breathing. You can imagine what would happen if you only had one nostril. So, two nostrils will make you sleep more relaxed and comfortable, even if one of them meets? Traffic jam? The other one will also work normally to ensure the breathing needs of the human body.
So in addition, are the nostrils on both sides? Is there a difference between left and right? Yes
As we all know, besides breathing, another function of nostrils is smell. In fact, the nostrils on both sides feel different about the same smell. Some scientific experiments show that when people smell through the right nostril, they often have a better impression of the smell, which often makes them feel happy and happy. The result of the left nostril will be more accurate.
Actually, it's nothing strange. The left and right nostrils are dominated by the ipsilateral brain, and the right hemisphere is responsible for controlling the sensation, so the right nostril will be unconsciously colored by emotions. The left hemisphere that dominates the left nostril is more rational and practical, so there are two different results. Of course, the difference is very small. It is impossible to smell bananas on the left nostril and chocolate on the right.
At the same time, breathing through the left and right nostrils has different effects on the human body. When breathing through the right nostril, the brain is easily excited and the nerves are in a state of tension. Usually, when you feel nervous in your study and work, you breathe through your right nostril. On the other hand, when you feel relaxed and happy, your left nostril is busy. The left and right nostrils take turns breathing, which is called nasal circulation in medicine.
In addition, German scientists also found that people with long and big nostrils tend to have a more sensitive sense of smell than others. Because the olfactory cells responsible for the sense of smell are distributed on the nasal mucosa, the strength of the sense of smell is directly proportional to the distribution area of the olfactory cells, so it is not difficult to understand why people with big noses have a sensitive sense of smell.
In a word, having two nostrils is scientific and also a sign of physical intelligence. Knowing this, take good care of and use our two nostrils.
