Nonetheless, it might be of only a limited value in advanced disease infecting the lower respiratory tract. It is especially useful in stage1 and stage 2 of the disease high concentration of virus in the oropharynx in asymptomatic stage and high viral loads in the upper respiratory tract during early disease states. Having a lipid coat, it is heat sensitive and rapidly loses viability/infectivity at 56☌ in 15 minutes (10000 units per 15 minutes) and then rapidly losing thereafter (>3 log10) becoming completely non-viable at 70☌.Īs per evidences, the coronavirus remains and proliferates in the nasophrynx and upper respiratory tract for up to two weeks after exposure and is thus amenable to application of steam. SARS COV-2 is a crown-shaped virus single-strand RNA with a lipid coat. As the coronavirus is an enveloped virus, is likely to be more heat-sensitive than other viruses. ![]() The steam inhalation seems a logical solution to COVID infection. A 2019 study showed that warm steam inhalation before bedtime helped participants relax and increased deep sleep, which led to improved sleep quality in adult men with mild sleep issues and anxiety. Steam therapy may also help people sleep. In addition to helping clear the nose and throat, steam therapy is sometimes used to help with chest congestion.įor example, in a 2018 study on steam therapy with a small group of people with chronic obstructive pulmonary disease (COPD), some participants experienced decreased respiratory rate and easier breathing.
