For a cough that’s worse at night, the fastest helpful steps are to sleep with your head raised , use a cool-mist humidifier , drink warm fluids , and try honey or cough drops to soothe your throat. Common triggers include postnasal drip, dry air, and acid reflux , so reducing those can make a big difference too.

What to do tonight

  • Elevate your head and upper chest with extra pillows or by raising the head of the bed. This can help with mucus pooling and reflux-related coughing.
  • Use a cool-mist humidifier to add moisture to dry air. Guidance from Cleveland Clinic and WebMD suggests keeping bedroom humidity around 40% to 50%.
  • Drink warm liquids like tea or warm water with honey. These can soothe irritation and may help loosen mucus.
  • Try a lozenge or cough drop to calm throat irritation and reduce the urge to cough.
  • Shower before bed if allergies or dust are part of the problem, because steam and rinsing off allergens can help.
  • Avoid eating right before sleep if reflux might be triggering the cough. Lying down soon after eating can worsen nighttime coughing.

If it seems like a specific cause

  • Postnasal drip or allergies: saline nasal spray, clean bedding, and an allergen-reduced bedroom may help.
  • Dry air: humidifier and warm fluids may help.
  • GERD or reflux: raise your head at night and avoid late meals.
  • Wet cough with mucus: an expectorant such as guaifenesin may help thin mucus.

When to get medical help

See a clinician soon if the cough is lasting more than a few weeks , getting worse, or comes with shortness of breath, chest pain, fever, wheezing, coughing up blood, or unexplained weight loss.

If you want, I can also give you a simple 1-night plan based on whether your cough is dry, phlegmy, allergy-related, or reflux-related.
