Are you thinking about why allergies occur and whether there is an ultimate cure for them?

The most common allergies include seasonal allergies, food allergies and environmental allergies. When triggered, you may experience problems with your nose, eyes and skin. 


How Do Allergies Occur

Allergies develop from the immune system's response to normally harmless substances (allergens) in the environment. The substances that cause allergies are usually in the air or in food. The condition behind allergies is called hypersensitivity. This occurs when the immune system reacts to something that is generally harmless. The body releases chemicals called histamines when the immune system reacts to an allergen. Histamines are responsible for the symptoms a person may have if they are allergic to something.

When a person has allergies, they often have symptoms such as asthma, runny or stuffy nose, sneezing, shortness of breath, headaches or itchy eyes or skin. Allergies can cause a person to experience any combination of the symptoms. The symptoms are often the same, depending on what a person is allergic to.

Allergies are usually caused by a level of sensitivity that one is born with. That means they are not contagious. Sometimes an allergy may develop after a person is exposed to an allergen. 

In most cases, the immune system of a person with an allergy to a particular material will have trouble tolerating even the smallest amount of the material. Some of the common allergens include pollen, mould, dust, dander, food, insect venom and medications. 

People are allergic to these substances because the body views them as being foreign to it. As a result, the body tries to fight off these substances by producing histamine. This can cause people to have allergic symptoms.


Can Allergies Be Cured

Many people believe that allergies can be cured. But in reality, there is no cure for allergies. You can only find ways to manage them and find relief. Here are some of the tips to manage allergies at home.

- Use air purifiers.

- Keep up with daily cleaning.

- Wash sheets and clothes more often.

- If you are sensitive to animal dander, use hypoallergenic pillows and blankets.

- If you are allergic to dust mites, wash your mattress and box springs once a week in hot water.

- Use allergen-proof covers on pillows and mattresses.

- Use one set of sheets for each person, and wash them often.

- Use a humidifier to prevent dry air.

- Use an air filter to remove dust and pollen from the air.

- Use a nasal rinse and nasal sprays.

- If you have allergic rhinitis, limit the exposure to pets, especially during the winter months.

- If you have allergic rhinitis, have your physician prescribe you the necessary medications.


Can Allergies Cause Sore Throat

Allergies can also cause a sore throat as well as inflammation. The inflammation that is often caused by allergies can make it hard for people to breathe. When people have a sore throat, it is often hard to swallow.

Nasal congestion is another reason why allergies can cause sore throat. When people have allergies, mucus forms in their sinuses and throats. The mucus blocks the sinus passages, which can lead to inflammation. 


What's the Difference Between Allergies and COVID-19

Allergies and COVID-19 share almost the same symptoms such as nasal decongestion and cough. However, allergies and COVID-19 have different causes. This is why it is important to be tested for COVID-19 to make sure that the diagnosis is correct to apply the necessary medications and treatment.



If you are suffering from allergies and are looking for ways to manage them, it is important to talk to your doctor or pharmacist. They can give you a diagnosis and suggest a course of treatment.
