What kind of tea can be consumed without affecting sleep?

Generally, drinking black tea, pu'er tea, lavender tea, chrysanthemum tea, and jasmine tea may not affect sleep. The detailed analysis is as follows:

1. Black Tea

As a fully fermented tea, black tea contains moderate levels of polyphenols and caffeine. Compared to more stimulating beverages like green tea, black tea's mild nature helps relax the nerves. Its theanine content helps relieve tension and promote physical and mental relaxation, thereby aiding sleep.

2. Pu'er Tea

Pu'er tea undergoes special fermentation processing, resulting in relatively low caffeine content. Additionally, components like polyphenols and amino acids in pu'er tea help regulate the nervous system, reducing anxiety and stress, thus improving sleep quality.

3. Lavender Tea

Lavender tea contains lavender essential oil, which has calming and soothing effects. Drinking lavender tea can relieve tension, reduce stress and anxiety, thereby aiding sleep.

4. Chrysanthemum Tea

Chrysanthemum tea not only does not affect sleep but also has a calming effect. Certain components in chrysanthemums can soothe the nerves, alleviate tension and anxiety, thus helping the body and mind relax and achieve deeper sleep.

5. Jasmine Tea

Jasmine tea is rich in natural fragrance, which can dispel irritability and has the effect of calming the nerves and aiding sleep. It can improve sleep quality, allowing for better rest at night.

It is important to maintain good sleep habits in daily life, such as keeping a regular schedule, avoiding strenuous exercise or watching stimulating movies before bedtime, which can help improve sleep quality and reduce the occurrence of insomnia.
