The experience of an acute respiratory illness, like COVID-19, often involves discomfort. While tea does not treat the underlying viral infection, it can serve as a comforting and supportive measure to help manage common symptoms. The primary purpose of consuming any warm beverage during illness is to maintain adequate hydration, a simple yet powerful component of recovery. Understanding the general mechanisms of warm liquids and the specific properties of certain ingredients helps individuals select teas that provide the most supportive relief.
Tea’s Role in Easing Common Symptoms
The physical act of sipping a warm beverage, such as tea, provides immediate, localized relief to irritated tissues in the throat and airways. This palliative effect is primarily mechanical, soothing the discomfort often associated with a persistent cough or scratchy throat. The elevated temperature of the liquid can also offer a subjective sense of improvement for symptoms like chilliness and tiredness.
Hydration is a particularly important function of drinking tea, as it directly impacts the consistency of the mucus lining the respiratory tract. When the body is dehydrated, mucus becomes thicker, making it harder for the body’s tiny hairs, known as cilia, to clear the airways efficiently. Consuming sufficient fluids helps thin the mucus, facilitating its movement and clearance from the nasal passages and lungs.
The steam rising from a hot cup of tea can act as a mild form of steam inhalation. This warm, moist air is thought to help temporarily relieve nasal congestion and sinus pressure. Although this effect is often subjective and temporary, the physical sensation of improved airflow can provide significant comfort during periods of nasal blockage.
Specific Teas for Respiratory and Immune Support
Teas derived from the Camellia sinensis plant, including green and black tea, contain polyphenols, which are natural compounds with antioxidant capabilities. Green tea is noted for its high concentration of catechins, such as epigallocatechin gallate (EGCG), due to minimal oxidation. Black tea undergoes fermentation, transforming its catechins into theaflavins and thearubigins, which also possess antioxidant properties. Both teas contribute to wellness by helping the body manage oxidative stress and are considered supportive of general immune function.
Many herbal teas, or tisanes, utilize ingredients traditionally known for respiratory comfort. Ginger tea, for example, contains gingerols recognized for their anti-inflammatory effects. It is also used to help settle an upset stomach or ease nausea, which can sometimes accompany illness.
Peppermint tea is frequently sought out for its potent menthol content, a compound that creates a cooling sensation and is a common ingredient in decongestant products. The menthol helps soothe inflamed mucous membranes in the sinuses and throat, which can provide a subjective feeling of clearer breathing. This tea is especially useful when congestion is a prominent symptom.
For individuals experiencing difficulty resting, chamomile tea is a popular choice for its calming properties. It contains an antioxidant called apigenin, which can bind to specific receptors in the brain to promote relaxation and aid in sleep quality. Ensuring adequate, restful sleep is an important element of the body’s recovery process.
Licorice root tea is often used to create a soothing, coating sensation for an irritated throat. However, it requires caution because it contains glycyrrhizin, a compound that can elevate blood pressure and decrease potassium levels, especially with chronic consumption. Individuals with pre-existing hypertension should avoid this tea or consult a healthcare provider.
Important Considerations When Using Teas
While tea is a safe and comforting beverage, its use must be viewed as a supportive measure, not a replacement for medical treatment or prescribed medications. If symptoms worsen, or if a person experiences difficulty breathing, persistent chest pain, confusion, or inability to stay hydrated, professional medical advice must be sought immediately. Tea is an aid for comfort, not a cure for a serious illness.
Careful attention should be paid to the temperature of the drink before consuming it. Drinking any beverage above 140°F (60°C to 65°C) is associated with a risk of thermal injury to the throat and esophagus lining. Repeated exposure to scalding hot liquids may contribute to an increased risk for esophageal cancer. It is advisable to let tea cool down to a comfortable, warm temperature before sipping.
Certain herbal teas contain active compounds that can interact with prescription or over-the-counter medications. For instance, teas containing herbs such as St. John’s Wort or Licorice root can affect the efficacy of drugs like blood thinners, blood pressure medication, or antidepressants. Patients taking regular medication should discuss the use of herbal infusions with a pharmacist or healthcare provider to avoid unintended interactions.
