The inhalation of steam, also known as steam therapy, is well known for relieving cold or sinus symptoms. Inhaling warm, moist air opens up the nasal passageways and relieves symptoms of irritation and swollen blood vessels. Moisture in your sinuses can also thin mucus, making them easier to empty, and you will be able to breathe normally again at least for a short while.

Furthermore, you can improve the health of your voice by inhaling steam. Those who sing or speak a lot at work can benefit from steam inhalation since it can moisten their voice box and soothe their vocal cords.

Steam inhalation is thought to be particularly useful when: 

  • Your voice feels hoarse or sore
  • Your throat feels dry 
  • You have a cough
  • You have a lot of mucus
  • You've been in a dry environment
  • You've been using your voice a lot
