Poor sleep

Because tea includes caffeine, excessive consumption may interrupt your sleep pattern. Melatonin is a hormone that alerts your brain to the fact that it is time to sleep. Caffeine may suppress melatonin synthesis, resulting in poor sleep quality, according to some studies. Inadequate sleep has been related to a number of mental health disorders, including exhaustion, decreased memory, and a short attention span. Furthermore, persistent sleep deprivation is linked to a higher risk of obesity and poor blood sugar management.

Caffeine is metabolized at varying rates in different people, making it impossible to anticipate how it will affect sleep patterns in everyone. Some studies have suggested that even 200 mg of caffeine ingested 6 hours or more before bedtime might have a deleterious influence on sleep quality, while others have found no significant effect. If you have signs of poor sleep quality and drink caffeinated tea on a regular basis, you should consider lowering your intake, especially if you also consume other caffeine-containing beverages or supplements.
