A representative from the CDC told Reuters that he was not aware of any scientific studies that show steam therapy helps with the coronavirus. Steam therapy can help thin mucus as a supplemental course of action to give some relief when grappling a cold or flu here but overall, scientific studies showing evidence of its usefulness are lacking here. Additionally, the practice brings risks. The usual technique of covering the head with a towel over a pan filled with hot water is dangerous due to the steam, the hot liquid, or even potential contact with the container.
These posts claim that inhalation of steam from boiling water, sometimes with various infused ingredients, will kill the coronavirus. This is false. Scalds are thermal burns caused by hot liquid, but the liquid may or may not be hot enough to reach boiling point. Steam burns can occur in people of all age groups, but children, elderly people, and patients with certain medical conditions are at a higher risk.
Steam burns can affect any exposed surface area of the body which includes the skin, mucous membranes of the respiratory tree, and eyes. Learn more about the symptoms, diagnosis, prevention, and treatment of steam burns, as well as the specific steps to take after sustaining a burn. Steam burns appear similar to other types of thermal burns.
In general, symptoms may include:. Steam burns can lead to complications when the steam is inhaled into the respiratory system or comes into contact with the eyes. When water reaches boiling point degrees Fahrenheit and turns to steam, this results in super-heated molecules that can cause nearly instantaneous scalding if they come into contact with body tissues. Steam is more likely to cause burn injuries than boiling water because of the latent heat of vaporization.
Since water expands to approximately 1, times its volume when it turns from liquid to steam, steam often escapes its container under pressure. It can emerge in a directed stream that can cause additional injury. Indeed, many household appliances count on this phenomenon to work—teapots, steam irons, vaporizers, and others. As a vapor, steam is easily inhaled and the super-heated molecules can travel deep into the upper respiratory system.
Vaporizers are particularly dangerous, especially for children, and there is no evidence to support their use in treating respiratory infection or shortness of breath. Kids are more likely to put their hands or faces directly in the stream of escaping steam from an appliance, resulting in a steam burn of exposed skin.
Kids are also more likely to develop epiglottitis during direct inhalation of steam. Microwave ovens use dielectric heating—radio waves agitate water molecules in food, which generates heat. The water molecules can turn to steam and expand, causing ruptures in solid foods. That's why solid foods including popcorn kernels sometimes "pop" in the microwave. One study identified eight patients who were injured by steam burns from exploding potatoes and eggs coming out of microwave ovens.
People with conditions that can lead to sudden losses of consciousness, such as syncope or seizures , are more likely to develop burns from all household appliances, including steam-generating appliances. Identifying steam burns requires obtaining an accurate history of the incident as well as identifying the actual burn.
Burns are categorized on a sliding scale of severity based on the size of the burned surface area and how much of the skin's thickness is affected by the burn called the "degree" of the burn. Classifications are either first, second, or third-degree burns. First-degree burns are identified by their redness and lack of blisters. A mildly red burn means that only the top layer of the skin the epidermis is injured.
A second-degree burn occurs when the epidermis is completely damaged and the burn injury extends into the next layer, the dermis. In most cases, a second-degree burn leads to separation of the top two layers of skin and weeping of fluid from the raw dermis underneath. This loss of fluid pushes the epidermis up, causing a blister. In steam burns, the blister pattern of a second-degree burn is often made up of very small individual blisters compared to other burn causes.
If the burn extends through both layers of the skin, this is known as a full-thickness, or third-degree burn. Of these injuries, 21 percent were to children 4 years old and younger. Many young children are more likely to be injured by scalding because of their natural child characteristics, such as:. Children also have thin skin, so even brief exposure to steam and hot liquids can cause deeper burns. People with a disability might have conditions that make them more at risk while moving potential scalding material, such as:.
Steam burns, along with liquid burns, are categorized as scalds. Scalds are a relatively common household injury, affecting children more than any other group. Steam burns often look like they have done less damage than they actually have and should not be underestimated. There are specific steps you should take when dealing with a scald from hot liquids or steam, including cooling the injured area with cool not cold water for 20 minutes. You can treat most first-degree and second-degree burns at home by running cool water over the area for 20 minutes.

Figure: Supply of heat of vaporization during vaporization and dissipation of heat of condensation during condensation Water requires a very large amount of heat to vaporize.
Figure: Energy flow diagram of vaporization and condensation This understanding now also explains why steam burns are generally much more painful and dangerous than water burns. Figure: Heat of condensation released during condensation of steam water vapor leads to severe burns Steam burns are more dangerous compared to water burns because additional latent heat is transferred in the form of heat of condensation!
