If you don't drink tea regularly, drinking Pu 'er tea will lead to insomnia. Pu 'er tea contains tea polyphenols, which will make people extremely excited. If you drink a lot of Pu 'er tea before going to bed, it will affect your sleep quality.

In daily life, if you don't drink tea regularly, try to avoid drinking tea before going to bed, which can improve the quality of sleep, and also avoid drinking coffee, spirits and other drinks, which can effectively avoid insomnia.

Identification method of Pu 'er tea:

1, tea appearance

The appearance of new Pu 'er tea is fresh, mostly yellow-green, with white hair and strong taste. After a long period of oxidation, the appearance of aged tea leaves will be purplish red, and the white hair will turn yellow-brown.

2. Color of wrapping paper

Usually, the white paper of aged Pu 'er tea has become obsolete with the passage of time, and the paper is slightly yellow. Therefore, the age of Pu 'er tea can be judged from the aging degree of hand-woven and printed paper. But this can only be used as a reference, not as an absolute basis, because some unscrupulous businessmen may take advantage of this psychology and package secondary products with yellow old wrapping paper.
