Tea is one of the most beloved drinks in the world, known for its warming and invigorating qualities.
However, behind the apparent harmlessness of this drink there are potential health risks, especially when consumed in excess.
Understanding these risks will help you enjoy tea without harming your body.
Effect on sleep and the nervous system
Frequent tea consumption, especially in the afternoon, can negatively affect the quality of sleep.
Caffeine, which is found in tea, is a stimulant of the nervous system. It can cause insomnia, anxiety, and increased nervousness.
People who suffer from sleep problems or are prone to anxiety should limit their tea consumption, especially in the evening.
Effects on the digestive system
Tannins contained in tea can irritate the lining of the stomach and intestines.
Frequent consumption of strong tea increases the risk of developing gastritis and other gastrointestinal diseases.
In addition, tannins can interfere with the absorption of some nutrients, particularly iron.
Effect on the cardiovascular system
While moderate tea consumption may be beneficial for the heart, excessive consumption may lead to adverse effects.
The caffeine in tea can cause increased heart rate and high blood pressure.
People with cardiovascular disease should be especially careful about the amount of tea they drink.
Impact on tooth enamel
Regular consumption of strong tea can lead to staining of tooth enamel. Tannins contained in tea can cause darkening of teeth.
Additionally, the acids present in tea can contribute to enamel erosion, especially if you drink hot tea immediately after meals.
Risk of dehydration
Although tea consists mostly of water, it has a diuretic effect due to its caffeine content.
If consumed in excess, this can lead to dehydration. This is especially important to consider in hot weather or during intense physical activity.
Effect on drug absorption
Some components of tea may interfere with the absorption and effectiveness of certain medications.
For example, tea can reduce the absorption of iron and some antibiotics.
People taking medications on a regular basis should consult their doctor about possible drug interactions with tea.
Risks for pregnant and lactating women
Pregnant and breastfeeding women are advised to limit their tea consumption. Caffeine can cross the placenta and into breast milk, affecting fetal development and the health of the newborn. In addition, tannins can hinder the absorption of folate, which is critical for fetal development.
Individual intolerance
Some people may have an individual intolerance to the components of tea. This may manifest itself in the form of allergic reactions, digestive disorders or other symptoms.
In such cases, frequent tea consumption can lead to chronic health problems.
Alternatives and moderation
Despite the potential risks, giving up tea completely is not necessary for most people.
The key to healthy consumption is moderation and mindfulness. You can alternate tea with caffeine-free herbal infusions or simply reduce the amount of tea you drink.
