No matter the season—sunshine, rain, or sudden cold spells—unpredictable weather changes can trigger allergic rhinitis. This condition is increasingly common, affecting more people each year. Being aware of the symptoms and taking proper care of yourself can significantly ease the discomfort. Otherwise, sudden weather shifts can bring on relentless allergy symptoms: nighttime breathing difficulties, poor sleep, puffy eyes, and lingering drowsiness throughout the day.

What Is Allergic Rhinitis?

Allergic rhinitis, commonly known as hay fever, is the inflammation of the nasal passages caused by exposure to allergens or abrupt weather changes. It leads to irritation, nasal congestion, and various disruptive symptoms. This condition affects people of all ages. While not life-threatening, it can seriously impact quality of life. If left untreated, it may progress to sinusitis. Genetics also plays a key role in susceptibility to allergic rhinitis.

Common Symptoms of Allergic Rhinitis

Symptoms to watch out for include:

  • Frequent sneezing

  • Nasal itching, congestion, and a “nasal” voice

  • Runny nose

  • Rubbing the nose, which may cause a crease across the bridge

  • Itchy, irritated, or watery eyes

  • Itchy ears, muffled hearing, or pain behind the ears

  • Postnasal drip, sore throat, and chronic cough

  • Occasional nosebleeds


How Is Allergic Rhinitis Diagnosed?

Diagnosis begins with a thorough medical history and a detailed symptom review. Your doctor will examine the nasal passages for swelling, assess mucus color, inspect the throat for redness, and observe dark circles under the eyes. Further evaluation may include laboratory tests such as:

  • Skin Prick Test to identify airborne allergens

  • Blood tests to detect specific allergen-related IgE antibodies

All diagnostic procedures are performed under medical supervision and based on clinical indications.

How to Treat and Prevent Allergic Rhinitis

  • Avoid known allergens identified through allergy testing

  • Minimize exposure to air pollution by wearing a mask outdoors and using air purifiers indoors

  • Rinse your nasal passages with saline solution to flush out mucus and allergens

  • Use steroid nasal sprays to reduce ongoing inflammation (not to be confused with decongestant sprays, which should not be used long-term)

  • Take antihistamines as needed to relieve symptoms

  • Consider allergen-specific immunotherapy (allergy shots or drops) to address the root cause. This treatment requires consistent follow-up with an allergy specialist

  • Surgical options may be recommended for patients with complications such as nasal polyps, deviated septum, or chronic sinusitis

  • Maintain a healthy lifestyle with a nutritious diet and regular exercise to support your immune system


How Severe Can Allergic Rhinitis Be?

Complications from allergic rhinitis can include asthma, conjunctivitis, acute or chronic sinusitis, middle ear infections, and even sleep disorders such as insomnia or obstructive sleep apnea. Without timely medical care, these issues can become chronic and severely impact daily life. In extreme cases, untreated asthma can lead to respiratory failure or even death.

Don’t wait—seek medical advice and take control of your allergies today.
