Haze Cough in Singapore: Two Simple Recipes for a Dry or Irritated Throat
You step outside, smell smoke in the air and, by evening, your throat feels rough. Then the dry cough starts just as you are trying to sleep. If that sounds familiar, begin with the simplest step: reduce your exposure to haze. Water, rest and two simple food-based recipes may make a mildly irritated throat feel more comfortable. A persistent, worsening or breathless cough needs proper assessment.
What can you do first
Check the latest NEA air-quality guidance before exercising or spending a long time outdoors.
Cut back on prolonged or strenuous outdoor activity when advised, especially if you are pregnant, older, a child, or living with heart or lung disease.
Sip water regularly. Warm fluids may feel soothing when your throat is dry or scratchy.
Keep taking prescribed medicines as directed, including asthma medication.
An N95 mask is generally unnecessary for a short commute. MOH advises that a healthy adult who must stay outdoors for several hours when the PSI is above 300 may reduce exposure with a well-fitting N95. Older adults, pregnant women and people with severe heart or lung problems should ask their doctor whether one is suitable.
Why does haze make you cough
Smoke and fine particles can irritate the nose, throat and airways. That may lead to a dry cough, sore throat, watery eyes or an asthma flare-up. But timing alone does not prove haze is the only cause. An infection, allergy, nasal irritation, reflux or another condition may be responsible, particularly if you also have fever, wheezing or symptoms that keep getting worse.
Two simple recipes for a mildly dry or irritated throat
If you otherwise feel well, these two recipes offer warm fluids and familiar food ingredients. In Chinese dietary therapy, their ingredients have traditional uses when dryness, throat discomfort or phlegm is prominent. Treat them as comforting foods and drinks — not as treatments that remove PM2.5, cure a haze cough or replace medical care.
1. Snow pear, white fungus and lily bulb soup
Serves 2–3 | Ingredients
2 snow pears
10 g dried white fungus
25 g dried lily bulbs, or about 50 g fresh lily bulbs
Rock sugar, to taste
Water, as needed
Traditional dietary use
Snow pear and white fungus are traditionally used in Chinese dietary therapy when dryness is prominent. Lily bulb is traditionally associated with nourishing and calming uses. These traditional descriptions do not mean the soup has been proven to prevent or treat the health effects of haze.
Method
Wash the snow pears thoroughly and cut them into pieces, leaving the skin on.
Soak the dried white fungus until soft, remove the firm base and tear it into small pieces.
Rinse the dried lily bulbs. If using fresh lily bulbs, separate and rinse the petals.
Place the pears, white fungus and lily bulbs in a clay pot or saucepan. Add enough water to cover the ingredients and simmer gently for about 1 hour.
Add rock sugar to taste and stir until dissolved. Allow the soup to cool to a comfortable temperature before serving.
Prepare soaked white fungus promptly. If you soak it overnight, keep it refrigerated. These are cooking quantities, not medicinal doses. Adapt the recipe to your usual eating plan if you have dietary restrictions, and stop if it causes discomfort.
2. Lemon, dried tangerine peel and honey drink
Ingredients | Serves 1
3–5 g dried tangerine peel
1/4 lemon
Honey, to taste
Rock sugar, optional and to taste
Warm water, as needed
Traditional dietary use
In TCM dietary practice, dried tangerine peel is traditionally used to regulate qi and transform phlegm. Lemon can make a warm drink feel refreshing, while honey may soothe the throat for some people. This drink is for comfort and hydration; it is not a treatment for haze exposure or an underlying respiratory condition.
Method
Rinse the dried tangerine peel and steep it in warm water for several minutes.
If using rock sugar, stir it into the infusion until dissolved.
Squeeze in the juice of 1/4 lemon.
Let the drink cool until comfortably warm, then add honey to taste and stir well.
Do not give honey to a child younger than 1 year. Lemon may aggravate reflux or feel irritating to some sore throats; leave it out if it makes symptoms worse. If you have dietary restrictions, adapt the drink to your usual eating plan.
Can TCM help with a haze cough
A TCM physician does not choose a cough remedy from one symptom alone. A dry, tickly cough may call for a different approach from a cough with a lot of phlegm. The physician may ask when the cough started, whether it changes with haze exposure, how it affects sleep, and whether you also have fever, wheezing, nasal symptoms or digestive changes.
You may hear phrases such as “moisten the Lung” or “nourish yin”. These are traditional treatment principles used when the overall pattern includes dryness. “Lung” describes a TCM functional system and is not identical to the anatomical lungs. If phlegm, throat pain or other symptoms dominate, the treatment plan may be different.
Evidence specifically for TCM treatment of haze-related cough remains limited. An individual consultation can help decide whether simple dietary care is enough, whether herbal medication may be appropriate, or whether you need medical assessment for another cause.
Should everyone drink cooling tea?
No. “Haze equals heatiness” is too broad a rule. A bottled drink, a light food-based tea and a concentrated herbal preparation are not the same thing. If you take medicines or herbal products, or if you are pregnant or breastfeeding, check before adding a medicinal tea. More ingredients do not automatically mean better relief.
What if there is phlegm?
Tell your physician how much phlegm you have, whether it is easy to bring up and what other symptoms come with it. Phlegm colour alone cannot select a TCM prescription, and a food-based recipe should not become the answer to every cough. If coughing repeatedly interrupts sleep or daily activities, arrange an assessment instead of continually adding ingredients to home remedies.
When should you get checked
Seek prompt medical care for new wheezing, blood in the phlegm, fever with a worsening cough, or worsening symptoms if you have a heart or lung condition. Arrange a review if your cough has not improved after two weeks or your sore throat lasts more than a week. Seek help earlier whenever symptoms are troublesome.
Call 995 for severe breathing difficulty, severe chest pain or loss of consciousness.
A final word from Physician Calista Lim
When haze leaves your throat dry, start small: reduce exposure, keep hydrated and pay attention to how your symptoms change. Either recipe may be a comforting addition if its ingredients suit you, but it should not delay assessment. If the cough lingers, affects sleep or comes with other symptoms, get it checked.

Frequently asked questions
Can I leave out the rock sugar during cooking?
Yes. Pears are naturally sweet, so you can prepare the drink without rock sugar. Adding more sugar does not provide better cough relief.
Can I add chuan bei?
Chuan bei (川贝) is a medicinal herb, so it should only be used under the guidance of a TCM physician. Different coughs require different treatments, so do not follow someone else’s prescription or dosage.
