Why Does Green Tea Make Me Pee? What Science Says
Have you ever had to run to the bathroom and take a pee after drinking green tea?
You’ve likely finished flushing and wondered to yourself why green tea can make you pee.
Is it a diuretic? Could it be the caffeine? Or maybe it’s one of green tea’s numerous health benefits.
Well, the answer lies in all of those assumptions.
Green tea will make you pee because it contains catechins. Caffeine acts as a mild diuretic which makes you urinate more often. While warm tea acts as a vasodilator which can enhance blood flow.
Now, if you want to understand why you pee more after drinking green tea or want to reduce your bathroom visits then keep on reading.
In this blog, we explore the research behind why green tea makes you pee, how much to drink daily and other reasons for frequent urination.
Why Does Green Tea Make Me Pee?
Green tea is known for its numerous health benefits, but it can also cause an increase in urination.
The primary reason green tea will make you pee is due to two components: caffeine and warm water. Caffeine acts as a mild diuretic, stimulating your kidneys, while warm water acts as a vasodilator that can enhance blood flow and increase urine production.
Additionally, drinking any liquid will naturally contribute to your need to urinate. Whether it’s green tea, coffee, warm liquids or any other tea will make you pee.
If you notice increased urination after consuming green tea, consider the volume of liquid you’re consuming alongside your usual daily intake and adjust accordingly.
How Much Green Tea Should I Take?
To enjoy the benefits of green tea without excessive urination, moderation is key.
Most experts recommend consuming no more than three to four 8-ounce cups of green tea per day. This amount is typically safe and provides a balance between the positive effects and potential side effects like increased urine production.
Be mindful of your caffeine sensitivity since everyone’s tolerances may vary. If you’re sensitive to caffeine then reduce the number of servings or opt for a decaffeinated variety.
Is Green Tea a Diuretic?
Yes, green tea acts as a mild diuretic due to its caffeine content. An e-ounce serving of green tea contains 25-50 milligrams of caffeine, which might be enough to cause urination.
Note that the diuretic effect of green tea is mild in comparison to other caffeinated beverages like coffee. The lower levels of caffeine in green tea are generally less likely to promote excessive urination.
However, with increased consumption of green tea, the diuretic effects may become more pronounced as the caffeine content builds up within your system.

Does Caffeine Make You Pee?
Caffeine is a natural diuretic, which means it helps your body eliminate excess water by increasing urine production.
Yes, caffeine can increase urine production, leading to more frequent trips to the bathroom. This is a temporary effect, and the intensity may vary depending on factors such as the brewing method and individual sensitivity.
Brewing tea for a shorter amount of time or with cooler temperatures will extract less caffeine. So, if you’d like to avoid excess urination then try different brewing methods.
Here’s a list of the most popular teas and their caffeine content:
| Type of Tea | Average Caffeine Content (per 8 oz cup) |
|---|---|
| Black Tea | 40-70 mg |
| Green Tea | 20-50 mg |
| Oolong Tea | 30-50 mg |
| White Tea | 15-30 mg |
| Pu-erh Tea | 30-70 mg |
| Earl Grey (a type of Black Tea) | 40-70 mg |
| English Breakfast (a type of Black Tea) | 40-70 mg |
| Matcha (Green Tea) | 70-80 mg |
| Chai (based on Black Tea) | 40-70 mg |
| Herbal Tea (like chamomile, peppermint) | 0 mg (caffeine-free) |
If caffeine acts as a stimulant then avoid black, tea, or matcha. Instead, try an herbal blend such as chamomile or peppermint tea.
Does Decaf Green Tea Make You Pee More?
Caffeine stimulates the bladder which may cause excess urination. For those concerned about the diuretic effects of caffeine, decaf green tea is a better option.
No, decaf green tea typically contains much less caffeine, which may cause less frequent urination.
However, decaf green tea may still contain trace amounts of caffeine. So, while you are likely to experience fewer trips to the bathroom, you may not be entirely free from the diuretic effects of decaf tea.
Can Green Tea Aggravate the Bladder?
Green tea is generally healthy due to its high content of antioxidants, vitamins, and minerals. However, it can sometimes cause bladder irritation and increase excess peeing.
Yes, green tea can aggregate the bladder due to its caffeine content. Caffeine acts as a diuretic which increases urine production and potentially causes discomfort for those with sensitive bladders.
Additionally, some people may find that compounds in green tea irritate the bladder lining. It’s also worth considering individual sensitivity and any pre-existing bladder conditions.
Good Alternative Teas to Green Tea
If you find green tea to be irritating, consider trying herbal teas instead.
Some examples of bladder-friendly herbal teas include chamomile and peppermint. These teas are caffeine-free and less likely to aggravate the bladder.
Here are some good alternatives to green tea:
- Chamomile Tea
- Peppermint Tea
- Rooibos Tea
- Lemon Balm Tea
- Hibiscus Tea
- Ginger Tea
- Licorice Root Tea
These herbal teas are caffeine-free so you’ll feel less of the diuretic effects. Here’s a list of 10 of the lowest caffeine teas if you need a different alternative.
Foods That Irritate the Bladder
Certain foods and beverages can exacerbate bladder issues, particularly for those with a history of urinary tract infections (UTIs) or kidney disorders.
Common irritants include:
- Caffeinated Beverages
- Alcohol
- Acidic Foods
- Tomatoes
- Spicy Foods
- Artificial Sweeteners
- Dairy Products
This means that some caffeinated teas such as green, black, or oolong tea will cause some mild diuretic effects. Although some teas are slightly acidic, the acid content is quite mild. Lastly, avoid adding artificial sweeteners to tea. Instead, use natural sweeteners such as honey or agave nectar.
For optimal bladder health, stay hydrated by drinking water and consuming natural diuretics, such as unsweetened cranberry juice. This will help flush toxins and minimize the risk of UTIs.
In addition to hydration, maintaining a balanced diet rich in vitamins, minerals, and antioxidants will promote overall health and reduce the likelihood of bladder irritation.
Other Reasons That Cause Frequent Urination
Besides the diuretic effect of green tea, other factors can lead to frequent urination. Age and weight can play a role, as older individuals and those with higher body weight might experience increased urination.
Diabetes: Diabetes is also a common cause of excessive urination, as high blood sugar can lead to increased urine production. This Urination research mentions that excessive urination occurs when your body makes larger than normal amounts of urine each day.
Urinary Tract Infections (UTIs): UTIs often cause frequent and painful urination. Infections in the kidneys can have a similar effect.
Enlarged Prostate: Men with an enlarged prostate gland might also experience increased urination, as the prostate can press against the urinary tract, causing discomfort and a constant urge to urinate.
Medications: Certain medications can lead to increased urine production and frequency.
Overconsumption: Consuming too many fluids, especially those containing caffeine or alcohol, can cause temporary excessive urination.
If excessive urination is an issue then be mindful of what’s causing the issue. It’s always important to listen to your body and take any changes into account.
Final Thoughts
Green tea’s caffeine can mean more trips to the bathroom. It’s a mild diuretic, so while it’s less potent than coffee, multiple cups could add up. To enjoy its benefits without overdoing it, try to stick to three to four cups a day. If caffeine bothers you, decaf green tea is an excellent lower-caffeine option, though it may still have traces.
