    There are a lot of articles about the benefits of black tea to human health, but we should know that excessive consumption of this kind of tea will bring negative effects to your body in many ways

    Although the side effects of black tea are rarely mentioned, it is important to understand these side effects and related symptoms if you do not want to affect your health due to excessive drinking of black tea

    The main side effects of black tea include: 1

    The astringent has the effect of astringent on the tannic acid of black tea, which occasionally leads to digestion problems

    This effect is more pronounced if you have constipation, irritable bowel syndrome or gastrointestinal disease

    Constipation is one of the side effects of black tea, and it is caused by tannic acid

    Drinking too much black tea will make it hard for the body to get rid of waste

    The main reason for this problem is that the intestine becomes dry and dehydrated due to the astringent of tannic acid

    Drinking tannic acid drinks can also cause iron deficiency

    Drinking black tea during pregnancy has been linked to impaired iron metabolism in newborns

    In addition, newborn babies also have the tendency of small cell anemia

    2

    The stimulative effect of black tea contains caffeine and other alkaloids, so it has stimulative effect on nervous system

    Drinking too much black tea (more than 5 cups a day) can cause side effects due to caffeine

    These adverse effects include headache, nervousness, insomnia, vomiting, diarrhea, irritability, irregular heartbeat, tremor, heartburn, dizziness, tinnitus, epileptic attack and blurred consciousness

    People who drink a lot of black tea or other caffeinated drinks are prone to form mental dependence

    That's why it's recommended for minors to drink a small amount of caffeinated beverages

    3

    Because black tea is a powerful diuretic, excessive drinking of black tea will lead to a large amount of electrolyte loss

    If it can not be made up by diet, it will have cramps and other symptoms

    No matter what kind of tea you drink, moderate consumption is very important

    Generally speaking, drinking 2-3 cups of black tea every day will not cause harm to health.
