Can people with neurasthenia drink Pu'er tea?
Generally, individuals with neurasthenia should avoid drinking Pu'er tea as much as possible. The detailed explanation is as follows:

Pu'er tea contains components such as caffeine, theophylline, and tea polyphenols. Excessive intake of these substances may increase neural excitability, thereby triggering or worsening symptoms of neurasthenia, such as mental tension and anxiety. Drinking large amounts of Pu'er tea in the afternoon or evening may cause difficulty falling asleep and sleep disturbances, further affecting the recovery of individuals with neurasthenia.
Neurasthenia may be caused by excessive stress, prolonged tension, sudden life events, or changes in lifestyle rhythms. Individuals with such conditions should avoid consuming foods and beverages that may stimulate the nervous system, such as teas containing caffeine, including Pu'er tea.
When choosing beverages, individuals should opt for those with little or no stimulation to the nervous system, such as warm water or milk. Additionally, individuals with neurasthenia should actively improve their lifestyle and undergo treatment and rehabilitation under the guidance of a physician.
