Мне кстати так и не ответили - как насчет дышать горячим паром, и компрессы на ухо, и прогревательные мази, и прочее? Надувают нас, стало быть? (А ведь мази и стимеры здесь продают, в Америке.) По вашей логике, ледяные компрессы тогда надо делать.
Я вчера ради интереса спросила у мужа, что он думает о мороженом, больном горле и иммунитете (мы с ним оба преподаем курс для медстудентов, где рассказываем им об устройстве дыхательных путей, иммунной системе, лейкоцитах и т.п., но я подумала, что может что-то упускаю). Его реакция - ну да, мороженое, чтобы снять боли в горле, нормально. Я говорю - "а вот люди беспокоятся, что это мешает иммунитету". "Ну эти люди небось еще и над картошкой теплым паром дышать любят - это их дело, если хочется так развлекаться".
Мне попадались статьи, где проверяли эффективность ингаляции - это не помогает лечить болезнь.

BACKGROUND:
Heated, humidified air has long been used by sufferers of the common cold. The theoretical basis is that steam may help congested mucus drain better and heat may destroy the cold virus as it does in vitro.
OBJECTIVES:
To assess the effects of inhaling heated water vapour (steam) in the treatment of the common cold by comparing symptoms, viral shedding and nasal resistance.
SELECTION CRITERIA:
Randomised controlled trials (RCTs) using heated water vapour in participants with the common cold or participants with experimentally induced common cold.
MAIN RESULTS:
We included six trials (394 trial participants). One study conducted in the USA demonstrated worsened nasal resistance, while an earlier Israeli study showed improvement. One study examined viral shedding and antibody titres in nasal washings; there was no change in either between treatment and placebo groups. Minor side effects (including discomfort or irritation of the nose) were reported in some studies.
AUTHORS' CONCLUSIONS:
Steam inhalation has not shown any consistent benefits in the treatment of the common cold, hence is not recommended in the routine treatment of common cold symptoms until more double-blind, randomised trials with a standardised treatment modality are conducted.

Effect of inhalation of hot humidified air on experimental rhinovirus infection.
OBJECTIVE:
Nasal inhalation of steam has been proposed as treatment of viral colds on the assumption that increased intranasal temperature will inhibit replication of rhinovirus (RV). The effect of steam inhalation on RV shedding by infected volunteers was examined in this study.
DESIGN:
Randomized controlled trial. Volunteers experimentally infected with RV were treated with machine-generated humidified air, which was either hot (active) or at room temperature (placebo). Viral shedding was assessed over the 4 days following treatment.
PARTICIPANTS:
Twenty volunteers from the university community who were susceptible to the challenge virus.
INTERVENTION:
Two 30-minute intranasal treatments, the first at 24 hours after inoculation and the second at 48 hours. The temperature of active vapor was 42 degrees C to 44 degrees C and of placebo vapor was 22 degrees C.
MAIN OUTCOME MEASURES:
Viral titers in nasal washings on each of 5 days following inoculation.
CONCLUSION:
Two nasal inhalation treatments with steam had no effect on viral shedding in volunteers with experimental RV colds.
