- Green tea (and matcha) contains theine: drunk too late, it can delay falling asleep.
- Its L-theanine, however, promotes relaxation: it's all a matter of dosage and timing.
- Drink it in the morning or early afternoon, and stop 4 to 6 h before bedtime.
- In the evening, opt for caffeine-free herbal teas (chamomile, verbena, rooibos, lavender).
Are you passionate about natural wellness, mindful of your health, and always looking for a healthy, energizing drink? Green tea is probably part of your routine. But you're wondering about the impact of green tea on your sleep. In this article, I'll explain everything: the effects of green tea on your night, the best time to drink it, and which alternatives to choose in the evening to preserve quality sleep.
The effects of green tea on sleep: what you need to know
Green tea, like matcha, is known for its many health benefits, notably thanks to its antioxidants and L-theanine, an amino acid that promotes relaxation and concentration. However, its theine content can sometimes raise questions, especially if you're trying to improve your sleep.
Caffeine and green tea: a balance to maintain
-
Green tea generally contains less caffeine than coffee (it's usually called theine), but it is definitely present.
-
Caffeine stimulates your nervous system, which can delay falling asleep if you drink green tea too late in the day.
-
On the other hand, L-theanine, found in green tea, helps calm the mind and reduces stress, promoting a more peaceful drift off to sleep.
Why green tea isn't necessarily the enemy of sleep
The key lies in the dosage and the timing. Drinking green tea in the late afternoon or early evening may be feasible depending on the person. But beyond that, caffeine is likely to affect your night.

Based on my experience and several studies, here's the impact that drinking green tea can have depending on when you drink it:
| Time of day | Impact on sleep | Recommendation |
|---|---|---|
| Morning (8h - 11h) | Natural stimulation | Ideal for a great start to the day |
| Afternoon (14h - 16h) | Gentle energy, alertness | Perfect for avoiding the energy slump |
| Evening (after 18h) | Risk of insomnia due to caffeine | Avoid it, opt for alternatives |
| Just before bedtime | Strongly discouraged | Counterproductive for sleep |
Drinking your green tea in the morning or early afternoon will let you enjoy its energizing benefits without disrupting your night. This is especially true for matcha, which is a high-quality green tea that provides lasting energy.

How to include green tea in your routine while protecting your sleep
Drinking green tea and sleeping well is possible if you adapt your routine. Here are my simple tips to fully enjoy the benefits of green tea without disrupting your nights:
-
Set a cutoff time: stop drinking green tea about 6 hours before bed to give theine time to be eliminated.
-
Reduce your theine intake: choose green teas naturally lower in caffeine

Can I drink decaffeinated green tea in the evening?
Yes, decaffeinated green tea retains its antioxidants and L-theanine while limiting caffeine. It can therefore be a good alternative to enjoy the taste of green tea without disrupting your sleep.
Is matcha recommended in the evening?
Matcha contains more caffeine than regular green tea. Even though it offers relaxing L-theanine, it's best to avoid consuming it in the evening to protect your sleep onset.
Can drinking green tea before bed help with weight loss?
No, drinking green tea before bed is not recommended for weight loss. The theine it contains can disrupt your sleep, and poor sleep actually hinders weight loss by disrupting hunger hormones (leptin and ghrelin).
To benefit from green tea's weight-loss properties, it's best to drink it during the day, ideally between meals and at least 4-6h before bedtime.
How long before bed should you stop drinking green tea?
I recommend not drinking green tea at least 4 to 6 hours before bedtime so that caffeine is sufficiently eliminated from your body.
Can green tea improve sleep quality?
Indirectly, yes. Thanks to L-theanine, green tea and matcha in particular can promote relaxation throughout the day and into the evening, even if you consumed it earlier. But you should avoid drinking theine late in the day so as not to disrupt your sleep cycle.
