Steam inhalation helps to relieve the symptoms of coughs and colds. Find out how to inhale steam and when it is better to use a nebulizer.

Steam inhalation is a natural home remedy for colds. However, it is only helpful when it comes to the sinuses and upper respiratory tract. The water droplets can’t reach mucus that is stuck in the bronchial tubes and is difficult to cough up. If that is the case, you better inhale an isotonic or hypertonic saline solution with a special device called a nebulizer.

This is how steam inhalation works:

  1. First boil two cups of of water and pour them into a bowl.
  2. Bend your head over the water and inhale the steam calmly and deeply – alternately through mouth and nose. If the steam is still too hot, wait a few more minutes till it has cooled down a bit.
  3. To increase the intensity, you can place a towel over your head and the bowl.

If you have a cold, you can inhale steam up to three times a day for up to ten minutes.

Important: If the bowl falls over, you can be severely burned. So make sure that it is firmly placed on the table and that the towel is only lightly draped over you. Smaller children should only inhale steam under supervision.

Stream Inhalation for Colds and Coughs: Salt or Essential Oils?

Eucalyptus, peppermint, pine oil – many herbal remedies help with a cold and are often used in steam inhalation. However, you should only use fresh or dried herbs like chamomile, never essential oils. Those can cause severe irritation to the eyes and other harm to asthma patients and children.

Inhaling saline solutions is also recommended when you have a cold. But that is not that simple. If you use bowl of saltwater, the steam evaporating from it will not have any salt in it. Water vapor can’t transport salt particles since salt boils at a much higher temperature than water. So, the dissolved salt stays in the water or dries out and becomes solid again.

Alternative to Steam Inhalation: Saline Solution and Nebulizer

Isotonic or hypertonic saline solutions break down mucus and moisten the mucous membranes – but only in aerosol form. For this kind of steam inhalation, you need a specially developed device called a nebulizer, available on Amazon**. However, you should only fill it with the sterile saline solution (NaCl, 0.9 percent) intended for this purpose. When you have a cold, a nebulizer will allow you to easily inhale while sitting upright.

Does Steam Inhalation Help Kill The Coronavirus?

While some sources do claim that steam inhalation can help relieve the symptoms of the coronavirus, others say that it cannot kill it. Neither the CDC nor the WHO currently recommend it. So, the effectiveness of steam inhalation when treating Covid-19 still remains unclear. What is clear, however, is taking preventive measures to protect yourself from contracting the disease in the first place. These include:
