Tea, particularly herbal teas, has a long history of traditional use in the prevention and management of colds. Across many cultures, drinking hot tea—whether black, green, or herbal—has been a common self-care practice for soothing symptoms and potentially preventing upper respiratory tract infections. The rationale is often based on the warmth and hydration provided by tea, as well as anecdotal beliefs about certain herbs or tea components supporting immune health. For example, green tea contains catechins with some reported antiviral properties, and herbal teas like chamomile or ginger are traditionally thought to support immune function.

From a scientific standpoint, the evidence is limited. While some laboratory studies suggest that polyphenols in tea (such as EGCG in green tea) may have antiviral effects, clinical evidence showing that regular tea consumption prevents colds is lacking. The hydrating effect and soothing warmth of tea may provide comfort and symptomatic relief, but robust clinical trials demonstrating a preventive effect are not available. In summary, the use of tea for cold prevention is primarily rooted in tradition, with only modest scientific support for some of its components but lacking direct evidence for prevention.
