Yes, certain teas can make you sleepy, while others may have the opposite effect. The impact of tea on sleepiness depends heavily on the type of tea and its caffeine content.
The Role of Caffeine
Many teas contain caffeine, a stimulant that promotes alertness. A hot cup of coffee or tea in the morning can make you feel awake and alert (NIH News in Health). However, excessive caffeine consumption can disrupt sleep.
Teas That Promote Sleepiness
Some teas, particularly herbal teas, are known for their relaxing properties and may promote sleep. These include:
- Chamomile tea: Chamomile is considered a mild sedative, relaxing the nervous system and potentially improving sleep (Sleep Foundation, Verywell Health). While it may promote relaxation, it's unlikely to cause significant daytime drowsiness (Verywell Health).
- Other Herbal Teas: Many other herbal teas, such as lavender, valerian, and passionflower, contain compounds that may have calming effects and help with sleep (Healthline).
The warmth and aroma of tea itself can also be comforting and soothing, contributing to a relaxing bedtime routine (reference 27). Having a cup of tea before bed can establish a calming pre-sleep ritual (reference 27).
Teas That May Not Make You Sleepy
The effect of other teas can vary. For example:
- Green Tea: Some green teas have lower caffeine levels than black tea and might be consumed before bed without significant impact (Healthline). However, even low caffeine amounts may affect some individuals.
- White Tea: The effect of white tea on sleepiness can be highly individual. Some individuals report feeling more calm, while others experience increased alertness (Reddit r/tea).
L-Theanine: A Key Component
L-theanine, an amino acid found in tea, is believed to play a role in promoting relaxation and sleep (Quora, NCBI PMC). Studies show that L-theanine can improve sleep quality (NCBI PMC).
Conclusion
The effect of tea on sleepiness is dependent on the type of tea and individual sensitivities. While some teas, like chamomile, are known for their relaxing properties, caffeine in other teas can have a stimulating effect. Therefore, the answer isn't a simple yes or no but depends on the specific tea chosen.
