When you are sick, a vocal steamer gives you warm water vapor, which UK hospital voice leaflets describe for soothing or relieving a dry throat. It is not a treatment for laryngitis, an infection or a lost voice, and we found no study, in the sources we checked, of steam for people who are ill. Some symptoms mean a doctor comes before a steamer, so start with the list below.

See a doctor first if any of these apply

The NIDCD's hoarseness page says to see a doctor if you:

  • have been hoarse for more than three weeks, especially if you have not had a cold or the flu
  • are coughing up blood
  • have trouble swallowing or breathing
  • feel a lump in your neck
  • have pain when speaking or swallowing
  • lose your voice completely for more than a few days

Steam is not a way to wait any of these out. If steam itself makes you cough, stop and ask a doctor about it.

This page does not diagnose, does not cover medicines and gives no timeline for getting better. Those are questions for your doctor.

Steaming with a cold: what hospital leaflets say

Four UK hospital voice leaflets we read (checked October 11, 2026) say what steam is for. Sherwood Forest's says only that it "helps to relieve a dry throat and decongest the nose". The other three also mention a cold, and they do not agree, so each is named.

Leaflet, and who it is for On steam On a cold, cough or infection
Royal Berkshire (people with voice difficulties) "Try steam inhalation to soothe a dry throat." "Rest your voice if you have a cold or sore throat."
St George's (people with voice difficulties related to head and neck cancer treatment) "plain water only, no oils - to loosen mucus / phlegm and relieve dryness" "Rest your voice and avoid excessive talking when you have a cough or cold, remember to steam and drink plenty of water."
West Suffolk (speech and language therapy leaflet) Called particularly helpful for a tired, sore or hoarse voice, in wording that also names "an irritating persistent cough or laryngitis" "(Only if you have a cold or throat infection, try 2-3 drops of Olbas® oil or tea tree oil in each inhalation as a decongestant.)"

These are leaflet lines, not study results. On oil they disagree: St George's says none, Royal Berkshire says you do not need to add anything, and West Suffolk allows drops only with a cold or throat infection. We quote West Suffolk's line as its wording, not as this page's advice.

What steam has not been tested for

The two steam experiments in our research library were not about illness:

  • Mahalingam & Boominathan, 2016. In 45 vocally healthy women aged 18 to 30, about 10 minutes of mouth breathing raised jitter and shimmer and lowered harmonics-to-noise ratio (acoustic measures of the voice signal). Three minutes of steam from a facial steamer moved them back toward baseline. Level of evidence 4.
  • Keltz & McHenry, 2022. Twelve women compared morning warm-ups with steam, straw-in-water phonation, or both. Results were highly variable: of 7 analyzed participants, steam was best for 1 and worst for 3, and those 3 strongly disliked it.

The favorable result is about healthy voices dried out by mouth breathing. Nothing we read measured steam in people with a cold, laryngitis, an infection or a lost voice. Does steam help vocal cords? has the detail.

What voice users do when the voice goes

People reach for steam anyway. In a survey of 288 professional voice users in Canada published in 2024 (MacDonald, You & Fung), 86% had used at least one complementary or alternative remedy when experiencing voice loss or a negative voice change. The most common were hot drinks with honey, lemon or both, lozenges, and inhaling steam; voice teachers and doctors most often influenced the choice.

A survey counts what people use. It does not show that any of these remedies works.

Rest and fluids, in the sources' words

On rest and fluids we repeat the sources and add nothing. The NIDCD's voice-care page says to drink water and take vocal naps. Royal Berkshire and St George's tie rest to a cold in the lines quoted above, and St George's adds: "Do not whisper. The tension caused by whispering does more harm than good." Sherwood Forest says: "If your throat starts to hurt or your voice deteriorates, rest your voice for 30 minutes to an hour."

The leaflets' daily fluid figures differ: 2 litres (Royal Berkshire), at least two litres (St George's), 6 to 8 glasses or mugs (West Suffolk).

If you steam while you are ill

The points below draw on two hospital sources and on the manuals of two makers: the Vicks V1200 manual (archived copy captured May 19, 2024) and the MyPurMist Free and Mypurmist 2 user guides, all checked October 11, 2026.

  • Hot water scalds. For a bowl, the Guy's and St Thomas' page, written for people recovering from vocal cord surgery, says not to use water that has just boiled. West Suffolk's mug method does use just-boiled water and warns you to "be extremely careful and never tip the inhaler container".
  • Nothing added to the water in an electric steamer. The Vicks manual says "Use with water only" and "Never add any medications or inhalant liquids to the Water Reservoir"; the MyPurMist Free and Mypurmist 2 guides say those devices are designed to work only with the maker's sterile water and that "any other water, additives, liquid, or water with minerals will damage the device".
  • Skip it if you are drowsy. The Vicks manual says "Do not use appliance while sleepy or drowsy"; the MyPurMist guides say "Never use while sleeping or drowsy."
  • Follow your manual for the rest. How to use a vocal steamer covers the steps.
  • This page is for adults. Nothing here is advice for a child; see are vocal steamers safe for kids?

Nebulized saline has not been tested for illness in our sources either. In Tanner et al. (2007), 60 vocally healthy women breathed dry air for 15 minutes, and afterward no nebulized treatment (isotonic saline, hypertonic saline or sterile water) significantly improved recovery of phonation threshold pressure, a lab pressure measure. For anything prescribed for a nebulizer, ask your doctor. For use when you are well, the Mayluck store has an article on portable nebulizers for singers, and its help center has a nebulizer safety page. Mayluck is sold by the company that owns this site.

Questions

Can a vocal steamer help with laryngitis?

It is not a treatment for laryngitis, and we found no study of steam for people who have it. West Suffolk's leaflet names laryngitis in the wording quoted above, and the MyPurMist Free and Mypurmist 2 user guides list "laryngitis" among their indications (manufacturer's statement, checked October 11, 2026). Neither is a study. If you have been hoarse for more than three weeks, the NIDCD says to see a doctor.

Does steam help a lost voice?

We found no study that tested it. Inhaling steam was among the most common remedies in the survey above, which records what people use, not what works. Losing your voice completely for more than a few days is on the NIDCD's see-a-doctor list.

Does a vocal steamer help a sore throat?

The leaflets differ. Royal Berkshire's steam line is about a dry throat ("Try steam inhalation to soothe a dry throat."), and for a cold or sore throat its line is to rest your voice. West Suffolk's leaflet calls steam particularly helpful for a tired, sore or hoarse voice. Neither is a study, and pain when speaking or swallowing is on the NIDCD's see-a-doctor list.
