As winter approaches, many people notice an increase in sinus- and ear-related issues. Symptoms such as nasal congestion, facial pressure, headaches, ear pain, and dizziness become more frequent during this season. According to Dr. Swapnil Brajpuriya, Associate Director & Head Unit II – ENT at Asian Hospital, the combination of cold air, low humidity, and sudden temperature changes are the main reasons why sinus and ear problems worsen in winter.Why Does Cold Air Cause Sinus Blockage?The sinuses are air-filled cavities within the facial bones that connect to the nose and play a key role in the breathing process. During winter, the cold, dry air dries out the nasal lining, causing the mucus to thicken. Thickened mucus slows down normal sinus drainage, leading to congestion and blockage.Dr. Brajpuriya explains, “In winter, the nasal mucous membrane tends to dry out, preventing proper drainage of mucus from the sinuses. This leads to congestion and sinus blockage.”The Link Between Ear Heaviness, Headache, and DizzinessThe sinuses and ears are connected via the Eustachian tube, which regulates pressure between the middle ear and the environment. When sinus inflammation or blockage occurs, it can create pressure in the ears, causing a feeling of fullness, reduced hearing, headaches, and sometimes dizziness.“Sinus infections can block the Eustachian tube, causing pressure buildup inside the ear. This pressure is often responsible for the headaches and dizziness experienced by patients,” says Dr. Brajpuriya.Why Are Infections More Common in Winter?Winter months often mean spending more time indoors in closed, crowded spaces, which increases the risk of viral and bacterial infections spreading. Additionally, colder temperatures and seasonal changes can weaken the immune system, making common colds and flu more likely to develop into sinusitis or middle ear infections.Dr. Brajpuriya adds, “If a cold or flu is not treated promptly, it can progress to a sinus or middle ear infection, particularly in children and the elderly.”Who Should Be Extra Careful?Certain groups are more susceptible to sinus and ear problems during winter. People with allergies, asthma, frequent colds, weak immunity, or pre-existing sinus conditions need to be extra vigilant. Smokers are also at higher risk, as smoke can irritate the nasal and sinus lining, exacerbating congestion and inflammation.Sinus Treatment and Prevention Tips To manage and prevent winter-related sinus and ear issues, Dr. Brajpuriya recommends the following precautions:Keep your nose and ears protected from cold air using scarves or masks.Stay hydrated by drinking plenty of water to keep mucus thin.Minimise exposure to dust and allergens indoors.Seek medical advice if nasal congestion, ear pain, or dizziness persists for more than a few days.He emphasizes, “Neglecting sinus and ear problems can lead to chronic infections. Timely treatment and proper care are essential to prevent complications.”Cold air, dry weather, and viral or bacterial infections are the key factors behind the increase in sinus and ear problems during winter. With simple preventive measures, adequate hydration, protecting the nose and ears, and seeking early medical care, most people can manage these seasonal issues effectively and reduce the risk of complications.
