What is laryngitis?
The larynx (voice box) contains the vocal cords, which vibrate to produce sound. When they are inflamed and swollen, they cannot vibrate normally, causing a hoarse, weak, raspy voice or complete voice loss (aphonia). Acute laryngitis lasts less than 3 weeks and is usually viral. Chronic laryngitis lasts longer and relates to smoking, reflux, allergy or chronic voice strain. See laryngitis and laringitis: tratamiento en adultos (Spanish).
Common causes
- Viral infections: cold, flu, COVID-19.
- Voice overuse or strain: shouting, singing, cheering, talking over noise.
- Acid reflux (LPR). See laryngopharyngeal reflux.
- Allergies and postnasal drip.
- Irritants: smoke, vaping, dust, chemicals and dry air.
- Bacterial or fungal infections (less common), including thrush from inhaled steroids.
- Alcohol and heavy coughing.
Remedy 1: voice rest, the right way
- Talk as little as possible for a few days; use text or writing.
- Do not whisper: it strains the vocal cords more than soft speaking.
- If you must talk, use a quiet, easy voice and short sentences.
- Avoid shouting, singing and talking over noise.
- Use a microphone or amplification for work if needed.
- Return to full voice use gradually.
Remedy 2: hydration and warm drinks
- Drink water regularly; aim for pale urine.
- Warm (not hot) herbal tea with honey and lemon soothes the throat.
- Broth and soup are comforting and hydrating.
- Avoid alcohol, caffeine and very hot drinks.
- Suck lozenges or hard sweets to keep the throat moist, choosing non-menthol versions if menthol irritates.
- Honey (a teaspoon) can ease cough; not for babies under 1.
Remedy 3: humid air and steam
- Use a cool-mist humidifier in the bedroom, cleaned regularly.
- Take steamy showers or inhale steam from a bowl of hot water with a towel over your head, carefully.
- Avoid dry, heated or air-conditioned rooms.
- Keep fluids up in the plane or car where the air is dry.
- Avoid dust and chemical fumes.
Remedy 4: avoid irritants and habits that slow healing
- Do not smoke or vape, and avoid secondhand smoke.
- Avoid throat clearing: sip water, swallow or do a silent cough instead.
- Avoid decongestants and antihistamines that dry the throat, unless needed.
- Avoid eating late, fatty or spicy meals if reflux is a factor. See home remedies for heartburn.
- Do not use numbing throat sprays to keep talking; they hide strain.
- Do not use steroid inhalers without rinsing the mouth afterwards.
Medicines and what doesn’t work
- Paracetamol or ibuprofen can ease throat pain.
- Saline nasal rinse and nasal steroid or antihistamine for allergy-related drip.
- Antibiotics are not helpful for viral laryngitis; a doctor may prescribe them for bacterial infection.
- Short courses of oral steroids are sometimes given to singers or professional voice users for urgent recovery, under medical supervision, since they carry risks.
- Reflux medicines if reflux is suspected.
- Cough suppressants are rarely helpful.
How long does laryngitis last?
Viral laryngitis typically improves within 3–7 days and resolves within 1–2 weeks. A voice that stays hoarse beyond 2 weeks should be reviewed, and beyond 3 weeks (earlier in smokers) requires an examination of the vocal cords, since nodules, polyps, paralysis, reflux damage or tumours may be responsible. See hoarseness and voice therapy.
When to see a doctor
- Hoarseness lasting more than 3 weeks, or 2 weeks in smokers.
- Difficulty breathing, noisy breathing or drooling: urgent.
- Pain or difficulty swallowing.
- Coughing up blood, a neck lump or unexplained weight loss.
- Hoarseness after neck surgery, intubation or injury.
- Professional voice users with recurrent loss of voice.
- Children with a barking cough, stridor or fever.
Three common situations
A teacher who lost her voice after a cold and a week of classes: voice rest, fluids, humid air and gradual return.
A fan who shouted at a match and is hoarse: rest for a few days; gentle voice use; hydrate.
A smoker hoarse for four weeks: needs a laryngoscopy.
For singers, teachers and other voice professionals
Professional voice users depend on their voice and cannot always rest it. If you must perform, speak or sing with laryngitis, seek a laryngologist’s opinion: a short course of oral steroids is sometimes used under supervision, but it is not risk-free, because a swollen cord pushed to perform can haemorrhage. Use amplification, shorten rehearsals, hydrate, steam, warm up gently and cool down afterwards, and avoid performing with a very hoarse voice. A speech-language pathologist can teach strategies and plan recovery. See vocal warm-ups.
Laryngitis in children
Children can develop laryngitis with colds, often with a hoarse voice and a barking cough (croup). Croup can cause noisy breathing (stridor) and needs medical attention if breathing is laboured. Keep the child calm, offer fluids and use a humidifier or cool night air as advised by your doctor. Seek urgent help for stridor at rest, drooling, inability to swallow, blue lips or exhaustion. Avoid cough medicines in young children.
Key points to remember
Laryngitis usually clears in 1–2 weeks with voice rest (no whispering), fluids, humid air, honey and avoiding irritants. Do not ignore hoarseness lasting more than 3 weeks or any breathing or swallowing problem. Our ENT team can examine your vocal cords.

Questions about home remedies for laryngitis
These answers are general information and do not replace an examination or individual medical advice.
What is the fastest way to cure laryngitis?
Voice rest, hydration, humid air and avoiding irritants; there is no instant cure.
Should I whisper with laryngitis?
No, whispering strains the cords; speak softly or rest the voice.
How long does laryngitis last?
Usually 1–2 weeks.
Do I need antibiotics?
Usually not; most laryngitis is viral.
Does honey help?
It soothes the throat and may ease cough, but it does not heal the cords.
When should I see a doctor?
If hoarseness lasts over 3 weeks or there is breathing or swallowing trouble.
