Some claim it aids slumber, while others believe it can disrupt the nocturnal rhythm. This blog post delves into the scientific evidence to unravel the truth behind the question: does green tea prevent sleep?
The Science Behind Green Tea and Sleep
Green tea contains caffeine, a stimulant that can interfere with sleep. However, the amount of caffeine in green tea is significantly lower than in coffee or energy drinks. A typical cup of green tea contains around 30-50mg of caffeine, compared to 95-200mg in a cup of coffee.
Caffeine’s Effects on Sleep
Caffeine works by blocking adenosine receptors in the brain. Adenosine is a neurotransmitter that promotes sleepiness. By blocking these receptors, caffeine can keep us alert and awake.
Green Tea’s Unique Properties
Despite containing caffeine, green tea also contains L-theanine, an amino acid that has calming and relaxing effects. L-theanine has been shown to reduce anxiety and improve sleep quality.
Studies on Green Tea and Sleep
Several studies have investigated the impact of green tea on sleep. Some studies have found that green tea can improve sleep quality, while others have shown no significant effect or even a slight disruption in sleep.
Factors Influencing the Effect
The effect of green tea on sleep may vary depending on individual factors, such as caffeine sensitivity, time of day consumed, and the amount consumed.
When to Avoid Green Tea Before Bed
If you are sensitive to caffeine, it is advisable to avoid consuming green tea close to bedtime. The caffeine in green tea can interfere with your ability to fall asleep and stay asleep.

If you enjoy the taste and health benefits of green tea but want to avoid potential sleep disruptions, consider the following tips:
- Opt for decaffeinated green tea.
