During the winter, the weather is usually colder and drier than usual, causing the nasal mucosa, skin, and respiratory tract to become easily irritated. People with allergies often experience flare-ups such as nasal congestion, frequent sneezing, itchy nose, coughing, or hives. However, these symptoms can be managed and reduced if you know the proper daily care methods.
Today Dr. Sasipa Saengkanjanavanich, Director of the Allergy and Asthma Center, Phyathai Hospital 2 will provide advice on how to take care of yourself during the winter to help reduce irritation and safely prevent allergy flare-ups with 7 simple care methods that help reduce allergy symptoms during winter, including
- Maintain humidity inside the house
Dry air causes the nasal mucosa to become easily irritated. Use a humidifier or place a bowl of water in the room to maintain humidity at about 40–50% to help keep the nose moist and breathing more comfortable, without increasing dust mites or mold growth. - Drink enough water
In cold weather, many people tend to forget to drink water, leading to dehydration and dry nose. Drinking warm water helps keep the respiratory system moist, reducing nasal congestion and cough. It is recommended to drink 6–8 glasses per day. - Take warm showers but not too hot
Very hot water strips moisture from the skin, causing dryness and increased itching. It is recommended to use moderately warm water and apply moisturizer immediately after showering to lock in moisture. - Clean the house regularly
Cold weather causes more dust accumulation, especially on curtains, carpets, bedding, and stuffed toys. Change bed sheets every 1–2 weeks, wash curtains and pillowcases regularly, and use a vacuum cleaner with a HEPA Filter to better trap dust mites. - Avoid sudden temperature changes
Alternating between cold and warm air causes the nose to react quickly and become more prone to allergies. It is recommended to wear a mask or face covering when leaving air-conditioned rooms, wear a coat when going out into the cold wind, and gradually adjust before entering very cold rooms. - Rinse the nose with saline solution
Nasal rinsing helps wash away allergens such as dust, pollen, or pollution, reducing nasal congestion, runny nose, and breathing difficulties. Choose sterile saline solution (Normal Saline) and appropriate equipment. - Boost immunity and get enough rest
A weak immune system makes you more sensitive to allergens. Eat a balanced diet with all 5 food groups, increase vegetables and fruits, get 7–8 hours of rest, and exercise regularly to support respiratory system balance.
When should you see a doctor?
If you have the following symptoms, you should see a specialist for evaluation
- Chronic nasal congestion lasting more than 2–4 weeks
- Chronic cough, sneezing, or runny nose
- Difficulty breathing or wheezing
- Frequent hives flare-ups
Cold and dry weather during winter can easily trigger allergy symptoms such as nasal congestion, cough, sneezing, or dry itchy skin. However, these can be prevented and relieved by daily self-care such as increasing humidity in the house, drinking enough water, taking moderately warm showers, cleaning the house regularly, avoiding cold winds, rinsing the nose with saline, and getting enough rest.
If symptoms are chronic or interfere with daily life, it is recommended to see a specialist for evaluation to plan appropriate treatment.
