Should You Drink Green Tea at Night

Green tea is one of the most popular drinks among people all over the world. However, its consumption during the day may not always be beneficial to health. Some studies have shown that drinking green tea at night can cause insomnia, which could lead to obesity and diabetes mellitus later in life. Other research suggests that it might increase your risk of heart disease and stroke.

So what’s the right time to drink green tea?

There are many opinions out there, but here are some facts to consider:

The best time to drink green tea is between 11pm and 6am.

If you’re a woman, you should avoid drinking green tea at night because it contains estrogenic compounds. (Estrogenic means they may affect hormones.) If you want to enjoy green tea with no negative effects, then it’s better if you consume it during the day.

For men, the best time to drink green tea is between 3pm and midnight.

It’s recommended that you don’t drink green tea at night unless you’re pregnant or breastfeeding. Drinking green tea at night increases your chances of developing high blood pressure and stroke. It also causes cancer in humans. (Source)

So how do you know when it’s safe to drink green tea?

Well, while there are benefits to drinking green tea all day, it’s best to drink it during the day if you want to avoid its negative effects. On the other hand, drinking it at night might help you sleep better. If you’re taking medicine that causes insomnia or keeps you up at night, then drinking green tea before bedtime is a good idea. It can also help reduce stress and improve your mood, making it easier for you to fall asleep.

So, when is the best time to drink green tea?

The answer really is up to you. If you want to consume the beverage all day, then go right ahead! Just be sure you don’t overindulge. And if you want to drink it at night, avoid drinking more than a few cups within a short period of time. In any case, make sure you don’t consume it during the hours before going to bed.

Can you drink green tea at night?

Yes, but only if you drink a moderate amount. Remember that drinking too much of any food or beverage can cause problems for your health, so don’t overdo it. Also, remember to avoid drinking green tea at night if you’re pregnant or breastfeeding. As for everyone else, here are some other things you should consider:

Green tea takes about half an hour before its antioxidant properties become effective. Since this is the reason why people drink it in the first place, it’s a good idea to wait 30 minutes before consuming it. (Source)

One of green tea’s main side effects is sleeplessness or insomnia. Drinking too much before bedtime might keep you awake for several hours. (Source)

Pregnant and breastfeeding women shouldn’t drink green tea before bedtime since it contains a lot of caffeine, which can reduce the quality of sleep. It can also cause miscarriages and premature delivery. (Source)

Green tea contains a small amount of oxalate, which can increase the risk of kidney stones in susceptible people. It’s not clear whether or not it poses a risk to the average person. (Source)

Green tea is a potent tool when it comes to losing weight and getting in shape. If you drink it before working out, it can also enhance your endurance and energy levels, allowing you to burn more calories in a shorter period of time.

As long as you don’t overdo it, green tea makes an excellent beverage throughout the day. If you’re pregnant or breastfeeding, however, it’s best to avoid drinking it at night.

Does green tea keep you up at night?

Green tea contains caffeine, just like coffee and soda. Caffeine is a stimulant that prevents the natural slowing down of your brain and body as the day goes on. It keeps you awake by blocking the effects of adenosine, a chemical in your brain that makes you feel tired as the day goes on. (Source)

Caffeine has a half life of 5-6 hours. This means that it takes 5-6 hours before half of the caffeine is removed from your body. If you consume more caffeine, the new amount gets added on top of the remaining old amount, which has a longer half life. You get the picture. Consuming too much caffeine can lead to unpleasant effects like headaches, nausea, and restlessness.


Green tea is slightly different from coffee and soda when it comes to its caffeine content. One cup of coffee contains between 100-200 milligrams of caffeine, while one cup of green tea contains 30-120mg. (Source)

If you’re used to drinking coffee on a regular basis and switch to green tea without making any other changes, expect to be a bit more alert and awake than you normally would be. If you drink a couple of cups in the morning, you might want to cut back on your drinking if you have trouble sleeping at night.

If you’re not used to drinking any caffeine at all and start drinking a few cups of green tea a day, you might also experience some of the side effects of too much caffeine.

Personally, I don’t experience any issues with green tea keeping me awake at night, but that’s probably because I don’t have more than one cup per day.

What’s the verdict?

Green tea is an excellent beverage for your body and health. It’s flavorful, delicious, and can even be good for your mental performance.

If you experience any side effects from drinking it, cut down on the amount that you’re drinking or just avoid it a few hours before bedtime. It’s not worth losing sleep over.
