Rhinitis It is a medical term that describes irritation and chronic or acute inflammation of the nasal mucosa.
It is a disease that can be caused by both viruses and bacteria, although it is most commonly manifested as a result of allergy, or by reactions to dust, smoke and other environmental agents. The inflammation resulting from rhinitis results in excessive mucus production which causes runny nose, the most typical symptom of rhinitis, clogging and itching. Allergic rhinitis, which is the most common form of rhinitis, is usually caused by airborne allergenssuch as pollen, dust mites, and the very peeling of animal skin, but can also be caused by an allergic reaction to itching, chemicals, cigarettes, and medicines.
Asthma is a chronic inflammation of the bronchi. There is swelling of the bronchioles and large phlegm production. Narrowing and excessive contractions of the bronchi make it difficult for air to pass through. The respiratory crisis manifests itself periodically. In addition to allergy to various substances, the causes of this disease may also be emotional factors, intense physical exercise, among others.
Symptoms of asthma are: difficulty breathing, but medicines must be prescribed by a doctor.
What a cough!
When impurities lodge in the throat or trachea, they need to be “cleared”. The glottis, a small opening at the top of the larynx, closes, trapping air in the lungs, which increases the pressure inside it. When the glottis suddenly opens, the air comes out with great force and speed, taking along mucus and dirt. This is a cough.
Similar situation occurs in the nose. Impurities and other agents cause nose or mouth irritation. The throat closes, trapping the air in the lungs, which increases the pressure within it. When the air comes back, it explodes and clears the airways, which means that it exits irritating particles. It's the sneeze.
When a person yawns over and over again, we know they are tired, sleepy, bored or inattentive. It is the brain's reaction by "warning" that your cells need more oxygen to produce more energy and thus continue their activities.
As we yawn, we inhale a lot of air, sending the body an extra load of oxygen.
