Infection-Induced Sleep Apnea: What Triggers It and How to Treat It

Ever woken up gasping after a nasty cold or sinus infection? That could be infection‑induced sleep apnea. When inflammation, mucus, or swollen tissue blocks the airway, breathing stops briefly during sleep. It feels scary, but knowing the signs and actions can keep you safe.

How Infections Trigger Sleep Apnea

Any infection that affects the upper respiratory tract can swell the throat, tonsils, or nasal passages. The extra tissue narrows the airway, making it easier for it to collapse when you relax in sleep. Common culprits include:

  • Viral colds and flu – increase mucus and cause throat swelling.
  • Sinus infections – fill the nasal cavity, forcing you to breathe through the mouth.
  • Strep throat or tonsillitis – enlarge tonsils and make the airway tighter.
  • COVID‑19 – can cause lasting inflammation in the airway and lung tissue.

When you lie down, gravity pulls the already‑narrow passage further closed. Your brain briefly wakes you up to restart breathing, which shows up as snoring, choking sounds, or a feeling of “air hunger.”

Managing Infection-Related Apnea

The first step is treating the infection itself. Antibiotics for bacterial infections, antivirals for flu, and plenty of rest can shrink swelling fast. While you recover, try these simple tricks to keep the airway open:

  • Sleep with your head elevated on a pillow or two – gravity helps keep the throat open.
  • Stay well‑hydrated; thin mucus is easier to clear.
  • Use a saline nasal spray before bed to wash out congestion.
  • Avoid alcohol and sedatives, which relax throat muscles even more.
  • If you have a CPAP machine, keep using it – it forces air through the airway and prevents collapse.

If symptoms persist after the infection clears, or if you notice loud snoring, witnessed pauses, or daytime fatigue, see a sleep specialist. They may suggest a short‑term CPAP trial, a mouthpiece, or in rare cases, surgery to remove enlarged tissue.

Remember, infection‑induced apnea is usually temporary. Treat the infection, support your airway at night, and you’ll likely be back to normal breathing in a week or two. If anything feels off, don’t wait – a quick check with your doctor can prevent bigger problems later.
