For many, a warm cup of tea is synonymous with comfort and relaxation. It's a beverage that has been enjoyed for centuries, celebrated for its soothing qualities and numerous health benefits. As per a study published in the Current Pharmaceutical Design, components like polyphenols that are found abundantly in tea help in reducing the risk of developing chronic diseases such as cancer, cardiovascular diseases, arthritis and diabetes.
However, as the saying goes, ‘Too much of a good thing can be bad for you.’ When it comes to tea, this adage holds true.
Caffeine Overload
One of the primary concerns with excessive tea consumption is the caffeine content. While tea generally contains less caffeine than coffee, it's still a significant source. Overconsumption of caffeine can lead to:
Insomnia
Excessive caffeine intake, especially in the afternoon or evening, can disrupt your sleep patterns, leading to insomnia or restless nights.

Increased Heart Rate
Caffeine can stimulate your heart, causing palpitations and an elevated heart rate, which may not be suitable for individuals with heart conditions.
Anxiety and Jitters
Too much caffeine can lead to nervousness, anxiety, and shakiness, making it challenging to stay calm and focused.
Dependency and Withdrawal
Regular consumption of tea can lead to dependency on caffeine. Missing your daily cup can result in withdrawal symptoms like headaches, irritability, and fatigue.
Dental Health
Tea contains tannins, which can harm your dental health:
Tooth Stains
Tannins can stain your teeth over time, leading to a yellowish or brownish discolouration.
Tooth Erosion
Tannins can erode tooth enamel, which is the protective outer layer of your teeth, potentially causing sensitivity and tooth decay.
Digestive Issues
Tea, especially when consumed in excess, can have adverse effects on your digestive system:
Upset Stomach
Tea is mildly acidic and can sometimes lead to stomach discomfort, especially when consumed on an empty stomach.
Constipation
Some compounds in tea can interfere with the absorption of minerals and water, potentially leading to constipation.

Nutrient Imbalance
Tea also affects the way your body enables the absorption of minerals and vitamins. Too much tea can have adverse effects, and increase or diminish the uptake of the following nutrients:
Iron Absorption
Tea, particularly black tea, contains compounds that can inhibit the absorption of iron found in plant-based foods and supplements. This can be problematic for individuals with iron-deficiency anaemia, as it can further reduce their iron levels.
Fluoride Content
Tea leaves, particularly older leaves, can accumulate high levels of fluoride from soil and water. Consuming too much tea with high fluoride content can lead tweak bones and teeth, and joint pain.
While moderate tea consumption can be a part of a healthy lifestyle and offer various health benefits, it's essential to be mindful of how much you're consuming. For most people, enjoying a few cups of tea a day is safe and can even provide antioxidants and other beneficial compounds. However, excessive tea intake can lead to caffeine-related issues, dental problems, digestive discomfort, and more.
