Health Inquiry


I would like to inquire whether drinking iced or hot black tea, milk tea, or fat-burning green tea is better for my health.
Will it affect my body health? Thank you for your response, doctor!

Dr. Cai Mengru reply Family Medicine


Dear Ms.
Ching,
Regarding your question, when consuming liquids at varying temperatures, they first pass through the oral cavity, where their temperature is adjusted to be close to body temperature.
The esophagus and stomach also have similar mechanisms.
Therefore, unless consumed in large quantities quickly or if the temperature difference is extreme, the temperature effects should not significantly impact the body.
Thus, please avoid gulping down beverages; at least pause in your mouth for a moment, and also avoid drinks with extreme temperatures.

Of course, excessive consumption of tea can have adverse effects, such as causing insomnia, palpitations, and headaches.
Additionally, beverages with high caloric content can lead to obesity, which may require more caution than their thermal effects.

Wishing you safety and health.
Sincerely,
Dr.

More Info


When it comes to the health implications of drinking hot or cold tea, there are several factors to consider, including the type of tea, the temperature at which it is consumed, and individual health conditions. Both hot and cold teas can offer health benefits, but they may also have potential drawbacks depending on how they are prepared and consumed.


Health Benefits of Tea
1. Antioxidants: Both green tea and black tea are rich in antioxidants, particularly polyphenols, which can help combat oxidative stress in the body. Green tea is often praised for its high levels of catechins, while black tea contains theaflavins and thearubigins, which also have antioxidant properties.

2. Heart Health: Studies have suggested that regular consumption of tea, particularly black tea, may reduce the risk of heart disease and stroke. The flavonoids in tea can improve blood vessel function and lower cholesterol levels.

3. Weight Management: Certain teas, like green tea, are often associated with weight loss due to their ability to boost metabolism. However, this effect can be modest and should be combined with a balanced diet and exercise for significant results.

4. Hydration: Tea can contribute to your daily fluid intake, which is essential for overall health. While some may worry about caffeine content, moderate consumption of tea is generally considered hydrating.


Hot vs. Cold Tea
1. Temperature Effects: Drinking tea at extreme temperatures (very hot or very cold) can have different effects on the body. Hot beverages can soothe the throat and may be beneficial for respiratory issues, while cold beverages can be refreshing and hydrating, especially in hot weather. However, consuming very hot drinks has been linked to an increased risk of esophageal cancer, so moderation is key.

2. Digestive Considerations: Some people find that hot tea aids digestion, while cold tea may be more refreshing. If you have a sensitive stomach or digestive issues, you might want to experiment with both temperatures to see which one feels better for you.

3. Caffeine Content: The caffeine content in tea can vary based on the type and brewing time. Green tea typically has less caffeine than black tea, and herbal teas are usually caffeine-free. If you are sensitive to caffeine, it’s important to monitor your intake, regardless of the temperature of the tea.


Potential Drawbacks
1. Additives: Many people enjoy adding sugar, milk, or cream to their tea, especially in the case of milk tea. These additives can increase calorie content and may contribute to weight gain or other health issues if consumed in excess.

2. Acidity and Stomach Issues: Some individuals may experience stomach discomfort from drinking tea, particularly on an empty stomach or if they consume it in large quantities. If you notice discomfort, consider adjusting the temperature or the type of tea you are drinking.

3. Caffeine Sensitivity: If you are sensitive to caffeine, consuming large amounts of tea, especially black tea, can lead to side effects such as insomnia, jitteriness, or increased heart rate.


Conclusion
In summary, both hot and cold teas can be part of a healthy diet when consumed in moderation. They offer various health benefits, including antioxidant properties and potential heart health advantages. However, it is essential to be mindful of how you prepare your tea and any additives you may include. If you have specific health concerns, such as asthma or digestive issues, it may be beneficial to consult with a healthcare professional for personalized advice. Ultimately, the best choice depends on your individual preferences and health needs. Enjoying tea as part of a balanced diet can contribute positively to your overall well-being.
