Green tea: harm and contraindications
If the benefits of green tea are usually known, then less is known about its dangers. Drinking this drink is contraindicated in the following cases: – with nervous exhaustion. Caffeine, which is abundant in green tea, stimulates the nervous system, so people suffering from nervous exhaustion may experience a lack of energy and sleep disturbance. It is better not to drink green tea before going to bed, as there is a risk of insomnia. It is not recommended to drink green tea and those suffering from hyperexcitability, as well as tachycardia; – women during pregnancy, breastfeeding and during menstruation. If you cannot stop drinking green tea in these cases, try to drink less of it; – for problems with blood pressure. Green tea often lowers blood pressure, and therefore, with hypotension in an acute form, drinking it is contraindicated, and with hypertension it should not be consumed in large quantities; – with chronic diseases. In these cases, green tea can be drunk in small quantities, because it can exacerbate the disease, as well as worsen the state of health. For example, drinking green tea for stomach ulcers can cause an increase in gastric acidity.
To enhance the beneficial effects on the body of green tea and avoid harmful effects, listen to the following recommendations: – do not drink green tea on an empty stomach. In this case, it irritates the stomach lining. It is better to drink green tea after meals, then it will help your digestion; – It is better to drink green tea not in the evening or at night, but during the day. Drinking before bedtime, a tonic drink instead of rest and sleep will present you with fatigue, headache and insomnia; – do not combine the use of green tea with alcoholic beverages. This has a very severe impact on the kidneys; – do not take pills and other medications with green tea. Although in this case it will not harm, but it will remove chemicals from your body, thereby reducing the effectiveness of medicines;
– do not use low-quality green tea. If you really want this drink to benefit you, not harm you, try to find real green tea, and not its surrogate in cheap bags. Manufacturers of such products focus on the convenience of brewing and cheapness, but not at all on the benefits of tea. Alas, the crushed tea leaf, oxidizing in the air, loses its properties. Producers will not spend high-quality and fresh tea leaves on the production of tea bags.
