Green tea tastes bitter and slightly cold. Drinking in cold winter is easy to cause stomach chills and may also affect appetite.

It's hot every day in summer, so drinking green tea can just take its bitter and cold nature, relieve summer heat and quench thirst. Moreover, due to the hot weather in summer, people consume a lot and sweat a lot, which easily leads to an increase in blood viscosity, and people are prone to fatigue and dizziness.

High blood viscosity brings great load to the heart. Green tea is astringent and rich in amino acids, which can relieve summer heat and cool down.

2, from the time of day to consider

There is a large amount of tannic acid in green tea, which will combine with protein to produce tannic acid protein, thus achieving convergence and weakening intestinal peristalsis, thus prolonging the retention time of food residues in the intestine, and then leading to dry stool.

Therefore, it is best not to drink tea after a full meal. Drinking tea one hour after a meal and two hours before going to bed is good, which can help digestion and replenish water.

Don't drink tea before and after meals, because drinking tea immediately after meals can combine tannic acid in tea with iron in food to form insoluble iron salt, which reduces the absorption of iron. It is easy to induce anemia after a long time. One hour after a meal, the iron in the food has been basically absorbed, and drinking tea will not affect the absorption of iron.

Never drink green tea before going to bed, otherwise it will affect your sleep.

Don't drink green tea on an empty stomach.

Drinking tea on an empty stomach will harm the body, especially for people who don't drink tea often, it will inhibit the secretion of gastric juice, hinder digestion, and seriously cause palpitations, headaches and other "tea drunkenness" phenomena. When drinking tea at night, put less tea and don't make the tea too strong.
