Sneezing
Sneezing is defined as the sudden and involuntary exit of
the air through the nose or through the mouth. People close their eyes as part
of the sneezing process. It is controversial that some people sneeze only once,
while others do not. They can stop sneezing after two or three or even five
times of sneezing, and this is due to the degree of irritation to the nose, as
the person will continue sneezing until the cause of the mucus irritation in
the lining of the nose is eliminated, it is worth mentioning that sneezing It
may result in a variety of reasons, which you buy All of which have irritation
in the mucous membrane in the inside of the nose or throat. In fact, sneezing
may in rare cases be a sign of a serious illness
Causes of Sneezing Sneezing is one of the most common
allergic symptoms, but it should be noted that in addition to the allergenic
factor, there are many other reasons for sneezing, including: [4] [5] Allergic
rhinitis: In this case, sensitive cells within the mucous membrane of the nose
are exposed to exposure to various allergens, such as pollen, mold, lint, dust,
and hay fever with histamine secretion, which affects the various nerves within
the nasal mucosa, The occurrence of sneezing, and also lead to histamine Other
symptoms of allergies, such as: nasal runny nose. Antihistamine, which works
against histamine that causes sneezing and runny nose, prevents the release of
histamine from histamine-1 receptors. Here, we note the presence of receptors
Histamine-1 in the airways, in the blood vessels, and in the digestive system.
The stimulation of these receptors can lead to rash, inflammation, tightness in
the airways, hay fever, and dizziness, as they exist in the brain and spinal
cord. To make the person more alert and alert. In fact, oral or nasal
antihistamines are an appropriate option for sneezing, but they will not be useful
for most non-allergic causes. It is important to take action to reduce
allergens, such as Clean oven filters, use air filters to reduce the amount of
pollen in the air, and wash linens in hot water to kill dust mites. Infection:
Respiratory infections such as colds cause sneezing. Colds produce mucus, which
in turn stimulates various nerves within the nasal mucous membranes. Sneezing
is a symptom that accompanies both colds and allergies. It is difficult to
distinguish between the two cases, but it should be noted that sneezing in the
case of cold is not caused by histamine, so most antihistamines do not expect
to help alleviate the symptoms, but some of the drugs that dry nasal
secretions, including some drugs Antibiotics Stamin can relieve sneezing, as well
as some anti-cholinergic nasal spray (Anticholinergic), which acts to prevent
acetylcholine from causing involuntary muscle movements in the lungs, digestive
system, urinary system, And other places of the body. [4] [6] Other irritants:
Black pepper acts as a chemical irritant to the nerves in the nasal mucosa,
causing sneezing, and other chemical irritants that can cause sneezing, strong
odors, perfumes, and smoke. Stimulants cause non-allergic rhinitis, because of
lack of Other allergens, such as bright sunlight, can cause sneezing because of
a reflex between the eyes and nose, which stimulates the nerves inside the
nasal mucous membranes and thus sneezes. Chemical and physical irritants do not
cause sneezing through the release of histamine, so conventional antihistamines
are not expected to treat the symptoms caused by these irritants. The use of
various nasal sprays, including nasal steroids (nasal steroids) ), Some nasal
antihistamines, and anti-cholinergic nasal spray are useful in the treatment of
sneezing caused by chemical and physical irritants. [4] [5] Exercise:
Hyperventilation, which results from exercise more than [7] Less common causes:
Nasal exposure to shock, discontinuation of use of drugs such as opioid
narcotics, and inhalation of irritants, including inhalation, Dust and pepper,
breathing cold air, in the occurrence of sneezing.
The importance of sneezing
Sneezing helps keep the body safe, healthy and free of
damage. It is an important part of the body's immune system and protects the body
by cleaning the nose of bacteria and viruses. If something enters the nose or a
catalyst, it does The sneezing center of the brain is located at the bottom of
the brain. The signals are then sent quickly to close the throat, eyes and
mouth tightly. After this, the muscles of the chest contract vigorously, and
then the muscles of the larynx quickly relax. As a result, the air is forced to
the saliva and mucus to exit. From the mouth and nose, and thus sneezing occurs
