Dry Cough but No Fever: 5 Possible Causes & Treatments
A dry cough without fever can be irritating and persistent. While it’s usually not a sign of a serious illness, it can still disrupt daily life. If you’re experiencing this symptom, here are five common causes and how to treat them effectively.
1. Allergies 🌿🤧
Cause: Exposure to dust, pollen, pet dander, or mold can trigger an allergic reaction, leading to a dry cough.
Symptoms:
✔ Itchy throat
✔ Sneezing
✔ Watery eyes
Treatment:
✅ Avoid allergens – Keep windows closed during high-pollen seasons and use air purifiers.
✅ Take antihistamines – Over-the-counter (OTC) medications like loratadine or cetirizine can help.
✅ Use a saline nasal spray – This clears allergens from your nasal passages.
2. Acid Reflux (GERD) 🔥
Cause: Stomach acid can travel up the esophagus, irritating the throat and causing a dry cough, especially at night.
Symptoms:
✔ Heartburn
✔ Sour taste in the mouth
✔ Cough worsens after eating or lying down
Treatment:
✅ Avoid trigger foods – Spicy, acidic, and fried foods can worsen symptoms.
✅ Eat smaller meals – Large meals can increase acid reflux.
✅ Use antacids or PPIs – Medications like omeprazole can reduce acid production.
3. Postnasal Drip 🤧💦
Cause: Mucus from the nose drips down the back of the throat, leading to irritation and coughing. It often occurs due to colds, allergies, or sinus infections.
Symptoms:
✔ Feeling of mucus in the throat
✔ Frequent throat clearing
✔ Worse at night
Treatment:
✅ Stay hydrated – Drink warm fluids like herbal tea to thin mucus.
✅ Use a humidifier – Moist air can ease throat irritation.
✅ Try a decongestant – Medications like pseudoephedrine can help clear nasal passages.
4. Asthma 🫁
Cause: A dry cough can be a symptom of mild asthma, especially if it worsens at night or after exercise.
Symptoms:
✔ Shortness of breath
✔ Wheezing
✔ Chest tightness
Treatment:
✅ Use an inhaler – A doctor may prescribe a bronchodilator to open airways.
✅ Avoid triggers – Common irritants include smoke, cold air, and strong odors.
✅ Try breathing exercises – Techniques like pursed-lip breathing can help.
5. Irritants & Dry Air 🌬
Cause: Exposure to smoke, pollution, or dry indoor air can lead to a persistent dry cough.
Symptoms:
✔ Cough triggered by smoke, perfumes, or dust
✔ No mucus production
✔ Worsens in dry environments
Treatment:
✅ Use a humidifier – Keeping air moist can prevent throat irritation.
✅ Avoid smoke & pollutants – Stay away from cigarette smoke and strong chemicals.
✅ Drink warm liquids – Herbal teas with honey can soothe the throat.
