Under normal circumstances, Pu'er tea helps people relax. When you feel stressed at work, taking a little time to slowly savor Pu'er tea can cultivate patience. Drinking Pu'er tea can relieve stress and ease your mood. In other words, if you are very tired, drinking Pu'er tea may make you want to rest and sleep—especially for those with suboptimal health conditions who may not realize that this sleepiness is caused by drinking Pu'er tea.

Many people also experience excessive alcohol intake, which deeply stimulates the nervous system. When the body's capacity is exceeded, symptoms such as confusion and lack of concentration may occur. According to the "Supplement to the Compendium of Materia Medica": "Pu'er tea is the best for treating mental cloudiness caused by greasy food, cleansing the intestines, and is the foremost remedy for sobering up." Medical evidence shows that tea polyphenols in tea can promote ethanol metabolism and protect the liver, allowing ethanol metabolism to proceed normally. Drinking tea can enhance vasoconstriction. Theophylline has a diuretic effect, helping to quickly expel alcohol from the body and reduce the harm after intoxication.

Drinking tea can also supplement the vitamin C needed for alcohol hydrolysis and stimulate the brain centers that have been numbed by alcohol, thus playing a role in sobering up. Moreover, using tea to relieve alcohol intoxication will never harm the spleen and stomach, nor cause heavy vomiting or the pain of nausea. Therefore, Pu'er tea does have a refreshing effect.
