The importance of nasal breathing
When people breathe, the nasal cavity is not only the passage of air, but also the air treatment factory because of the particularity of nasal cavity tissue structure. "This factory is like an air conditioner", which has the functions of warming air, humidifying air and purifying air.
The blood vessels of nasal mucosa are very rich, which have the functions of contraction and expansion, and can adjust themselves with the changes of internal and external environment. When cold air enters the nasal cavity, the blood in the small blood vessels increases and the flow is accelerated, so that the cold air entering the nasal cavity can be adjusted to a temperature close to the body temperature; At the same time, dry air can be changed into moist air to maintain normal physiological activities of respiratory tract.
There are a lot of nose hairs in the nostrils. Breathing through the nose can block a lot of dust in the air. Sometimes, the irritating gas in the air stimulates the nerve tissue in the nasal cavity, and they sneeze together, ejecting coarse soot and harmful gases.
The inhaled air is basically sterile, which is mainly due to the role of mucous glands and mucoepithelial cilia in the nasal cavity. Dust and microorganisms in the air are inhaled into the nasal cavity, adsorbed on the mucus blanket, and swallowed or spit out with the movement and swallowing of cilia. At the same time, the mucus secreted by nasal cavity also contains a bacteria-containing enzyme, which can inhibit and dissolve bacteria. The respiratory function of the nasal cavity is closely related to human health. Keep the nasal cavity clean at ordinary times, and don't pick your nostrils casually. Once the nasal cavity is blocked and interferes with normal breathing, you should consult a doctor.
Developmental characteristics of children's nose
The nose is the initial part of the respiratory tract and the gateway for gas to enter and exit; It is also an olfactory organ. The nasal cavity structure of children is different from that of adults;
(1) Children have short noses and nasal cavities due to facial and cranial hypoplasia. Newborns and children born for a few months have almost no inferior nasal passages. Later, with the growth of age, the development of facial skull and maxilla, the teething and nasal passages gradually became longer and wider. At the age of 4, the inferior nasal meatus was completely formed.
(2) Infants and young children have no nasal hair, weak nasal mucosa and rich blood vessels, and are susceptible to infection. When infected, due to congestion and swelling of nasal mucosa, the narrow nasal cavity often becomes narrow or even occluded, resulting in dyspnea. Even with the common cold, infants may have difficulty breathing, refuse to eat milk and be agitated.
(3) The infant's sinuses are underdeveloped. At birth, although the frontal sinus and ethmoidal sinus have been formed, they are very small, while the frontal sinus and sphenoid sinus are completely undeveloped. Later, with the increase of age, the facial skull and maxilla gradually developed, and the sinuses also gradually developed. However, the development of each sinus is not completely consistent, such as maxillary sinus, which begins to increase rapidly after 2 years old and is wide and deep at 6 years old; The development speed of ethmoid sinus is similar to that of maxillary sinus. Frontal sinus began to appear in the second year after birth, and it was pea-sized at the age of 6, and it was fully developed at the age of 12 ~ 13. The sphenoid sinus did not communicate with the nasal cavity until the age of 3, and this cavity began to increase rapidly at the age of 6. Because of the hypoplasia of children's sinuses, it is easy to cause respiratory infection, but it rarely causes sinusitis.
(4) Children's nasolacrimal duct is short, and the valve at the opening is underdeveloped, which is located in the inner canthus. Therefore, children's upper respiratory tract infections often invade the conjunctiva, leading to symptoms such as redness and swelling of eyelids and more gums.
Protect your nose in winter.
Traditional Chinese medicine believes that the nose is the opening of the lung, the portal of the respiratory system and the main channel for evil spirits to invade the lung. Strengthening the protection of respiratory organs such as nose in winter can not only prevent colds, but also prevent respiratory and cardiopulmonary infections. vehicle
The nose is close to the brain, the lower part is connected with nasolacrimal duct and eyes, the nasopharynx behind the nose is connected with the throat, and it is also connected with the middle ear through eustachian tubes on both sides. Because the nasal cavity extends in all directions, the nose is sick, which often affects the health of neighboring organs.
In addition, the human body inhales oxygen and spits out waste gas, and it depends on the nose to play its role. The nose can filter and heat the inhaled air, which is the first line of defense to prevent the invasion of bacteria and viruses. There are many nasal hairs in the nasal cavity, which secrete nasal mucus, so the nasal cavity is a place where many allergens such as bacteria, dust and pollen gather. When the body's resistance drops, the nasal cavity is the source of the spread and spread of bacteria and diseases. Then it will induce various respiratory diseases such as headache, nasal congestion, olfactory failure, nosebleeds, otitis media and even brain diseases, causing serious adverse consequences.
How to protect your nose in winter?
In winter, we should insist on outdoor activities, breathe more fresh air, wash our nose with cold water, and improve the blood circulation of nasal mucosa. Proper massage of the nose every day is of great significance to enhance the function of the nose and prevent related diseases. In winter, eat more medicinal foods such as pears, lotus roots, bananas, tremella, radishes, honey, walnuts, sesame seeds, etc., and eat less spicy and irritating foods that are too dry, which can prevent the nasal cavity from getting angry.
How to help the baby clean his nose?
Nasal congestion in newborns is very common.
Many parents find that the baby's breathing sounds like snoring when sleeping. This is because the baby's nose is blocked. This is not a cold, but because there are secretions blocked in the nose, which leads to poor breathing and snoring-like sounds, which may occur day and night, and this situation will gradually improve until the baby is two months old!
The baby's nasal cavity is narrow, the sinus is immature, the nasal mucosa is particularly sensitive, and it is easy to have a runny nose and stuffy nose when sneezing, touching cold air or crying. What's more, the baby's nasal mucosa, like adults, has a normal amount of secretions every day, sometimes it will dry and harden, blocking the baby's narrow nasal cavity, and with every breath, it will cause nasal congestion in the baby's nose. If the baby's nose is blocked, it will not sleep well all night, so it is necessary to clean the baby's nose often so that they can breathe smoothly and there will be no snoring.
How to help the baby clean his nose?
1. If you can directly see a blockage or secretion in your nose, dip a baby cotton swab in some water or baby oil to get wet, and then reach into your nostrils (not more than 2 cm) to take out the secretion. Avoid entering the nasal cavity too deep to avoid injury.
2. Hot compress your nose with a wet towel. After the nasal mucosa contracts, the nasal cavity will be more unobstructed, and the sticky nose will easily hydrate and flow out.
Matters needing attention
1. When using a cotton swab, be careful not to let the cotton swab hurt the nasal mucosa, because the baby will move.
2, the baby will use sneezing to remove foreign bodies in the nostrils, and sudden encounter with cold air will also cause sneezing. This is normal, unless you have a runny nose, don't worry.
3, sometimes the doctor will advise the baby to suck a little wet steam, you can use the bathroom to put hot water to steam, suck for three or five minutes, and then take your nose away.
4. When using a heater or electric heater for heating in winter, you should pay attention to the problem that the air is too dry, the baby's nose will be uncomfortable, and the room needs humidification.
If the blockage is too serious, please ask the doctor to use special small instruments to help deal with it.
Five maintenance details make nose more beautiful
1. Blackhead acne
Blackheads are natural enemies of white skin. In the nose and its surrounding areas, there is often oil secretion, which will eventually harden and become blackheads after oxidation. The effect of nasal paste is not thorough, and frequent going to beauty salons is not small harm to the skin and pores of the nose, so it is very important to remove blackheads in daily care.
You can use deep exfoliating cream to exfoliate regularly; Buy plant blackhead softening milk, apply it to blackheads, and wash it after 10- 15 minutes (usually 2-3 times a week, and use it every day in severe cases); Then shrink pores to regulate water, converge pores and reduce oil secretion.
2. Large pores
The nose is a part rich in oil secretion. With the growth of age, improper use of skin care products will make pores bigger and bigger. The nose is the most prominent part of the face, and large pores will affect the appearance. Deep cleaning and exfoliation should be carried out regularly at ordinary times, and the cleaning method should be correct every day to avoid the accumulation of oil and dirt in pores; After washing your face, pat on mild shrinking water (or toner) containing astringent ingredients and pat gently from bottom to top. After a period of time, it will make the pores look much more detailed, and it will also inhibit sebum secretion.
glistening
You don't want your nose to shine like a light bulb when the other person stares at you! Adequate sleep, normal work and rest, avoiding staying up late, drinking more water, and using astringent water frequently are the only ways to control oil secretion. You can also use oil-absorbing paper, but not too many times, just twice a day.
Step 4 dye
The appearance of color spots will always make the skin have a little regret, and a few spots on the tip of the nose can be regarded as cute when I was a child; But as an adult, it is not good-looking. Using qualified whitening and freckle removing products can fade spots. It should be noted that it is said that lemon juice can whiten skin, and lemon contains vitamin C that can whiten skin. However, the vitamin C in unrefined natural lemon can not be directly absorbed by the skin, and it also contains a component called solanine, which is easy to form spots. If you put lemon peel or lemon juice on your face and bask in the sun, the chances of long spots will greatly increase.
5. Red
Eating too much chocolate and other sweets may cause the capillaries of the tip of the nose to dilate, thus the tip of the nose is red; Women who have the habit of eating snacks can use nuts, fruits or yogurt instead. If the whole nose is red, in addition to the cold climate and other reasons, we should also consider whether the heart is overburdened and whether there is rosacea, and go to the hospital for treatment in time.
