Explain the connection between allergies and difficulty breathing through the nose
Hay fever is a common condition that affects many people. It happens when your immune system overreacts to harmless things like pollen, pet fur, or dust mites. These things are called allergens. For people with hay fever, allergens can cause an immune response.
When someone with hay fever touches something they’re allergic to, their body thinks it’s dangerous. It releases chemicals like histamine. The histamine makes blood vessels in the nose swell up. This swelling causes congestion or trouble breathing through the nose.
Hay fever can cause sneezing, an itchy nose or throat, watery eyes, and postnasal drip. How bad the symptoms are depends on the person and their exposure to allergens.
People with hay fever need to figure out what causes their symptoms and avoid those triggers. This can help them manage their symptoms better.
Histamine can make the nose swollen and the blood vessels in the nose inflamed. When the nasal passages get inflamed and swollen, it makes it hard to breathe through the nose. The allergic response causes swollen tissues and extra mucus, which blocks the nose.
When people have allergies, their noses can get congested because of inflammation. This congestion makes it harder to breathe through the nose. Blocked nostrils are caused by the immune system’s response to harmless allergens. If people with allergies know this link, they can control symptoms and improve nasal breathing.
Respiratory Infections Cause Nasal Congestion
Causes of Nasal Congestion
Respiratory infections like the flu or cold mainly affect the upper respiratory tract. This includes the nose, throat, and sinuses. One of the main symptoms is nasal congestion.
When we get an infection, our immune system releases chemicals to fight the viruses or bacteria.
Immune Response Leads to Swelling
This immune response causes inflammation in the nasal passages. It also increases mucus production. The inflammation and extra mucus make the blood vessels in the nose swell. This swelling leads to nasal congestion.
Symptoms of Nasal Congestion
Nasal congestion makes it hard for air to pass freely through the nostrils. It creates a stuffy or blocked feeling. Breathing through the nose becomes challenging.
Lying down at night makes congestion worse. Gravity causes fluid buildup in the sinuses.
The inflammation and mucus make the nasal blood vessels swollen. This makes breathing through the nose uncomfortable. Understanding how infections impact breathing helps manage symptoms. Seeking medical care may help if symptoms continue.
