Pu 'er tea is the only post-fermented tea in the world, and its theophylline and tea polyphenols are less than ordinary tea, so drinking it will not affect sleep, but will promote sleep. Tea is generally alkaline and can neutralize a small amount of stomach acid. The following is a detailed introduction to the question of whether drinking Pu 'er tea affects sleep.

The lighter the degree of fermentation, the greater the influence on sleep, because the theophylline and caffeine contained in tea have the function of exciting the central nervous system. The heavier the fermentation, the less the theophylline and caffeine contained in tea. From the tea soup, we can roughly judge the degree of fermentation of tea. The tea in green tea soup is basically not fermented, the yellow and reddish soup colors are basically semi-fermented, and the tea in red soup color is basically fully fermented, so it is best to drink the tea in red tea soup after dinner without affecting sleep, except for tea sensitive person.

Caffeine is the main substance that affects sleep in platform tea, and the content of caffeine is the highest in fresh tea, with 70 mg of caffeine per 100 ml in green tea. The content of caffeine in black tea is higher than that in Pu 'er, reaching about 60 mg per 100 ml. Tibetan tea belongs to black tea, and its fermentation period is long. In the process of purification and substance complexation, caffeine decays more, about 20 mg per 100 ml.

Wish you a happy tea!
