Drinking green tea is easier to fall asleep than drinking black tea. In the process of making and fermenting tea products, tea polyphenols and caffeine in black tea are greatly reduced, and the irritation is weakened. In the process of green tea fermentation, there are relatively many tea polyphenols and caffeine residues, which are also very irritating, which are more likely to affect sleep and even lead to insomnia.
