What kind of tea can I drink in the evening without affecting sleep?

Generally, drinking moderate amounts of black tea, pu'er tea, lotus tea, lavender tea, or dandelion tea in the evening usually does not affect sleep. The detailed explanation is as follows:

1. Black Tea

Black tea is a fully fermented tea with low levels of tea polyphenols, which can aid digestion and relax the body. Due to its milder nature after ripening, moderate consumption of black tea does not significantly impact sleep.

2. Pu'er Tea

Pu'er tea is a fermented tea with a mild nature and relatively low levels of tea polyphenols, resulting in less stimulation. Moderate consumption of pu'er tea can promote metabolism without affecting sleep quality.

3. Lotus Tea

Lotus tea is mild in nature and has effects such as clearing heat and detoxifying, calming the mind, and relieving stress. Drinking lotus tea in moderation helps relax the body and mind and does not negatively affect sleep.

4. Lavender Tea

Lavender has the effects of relieving stress, purifying emotions, and calming the nerves to aid sleep. Drinking lavender tea in moderation can relieve tension and promote better sleep.

5. Dandelion Tea

Dandelion tea is rich in vitamins and minerals and has sleep-promoting properties. Drinking dandelion tea in moderation can improve sleep quality and reduce insomnia issues.

In daily life, it is important to control the timing of tea consumption, avoiding drinking tea before bedtime. Additionally, one should choose teas with higher fermentation levels, such as black tea and pu'er tea, and avoid unfermented teas like green tea to prevent sleep disturbances.
