Reasons Not To Be Drinking Green Tea Before Bed


In this post, I will discuss the reasons why you should not be drinking green tea before bed. Drinking healthy beverages is great but you must know the proper time when to drink it. This would maximize its good effects, and not be detrimental to your health. What about green tea? Is there a difference when you drink it before bedtime or not? I will answer this question after presenting some brief facts about green tea.

What is Green Tea?

Green tea originated from India and is derived from the leaves of the Camellia sinensis plant. It's different from other teas because it's not withered and dried but steamed instead. This process would eliminate the enzymes responsible in destroying the green color of the leaves.

It contains several substances that can help you maintain good health. It contains substances that are anticarcinogenic, antioxidative, and antimutagenic.

Here are some of these vital substances and their health benefits:

Components of Green Tea and Their Health Benefits

1. Anti-oxidantsPolyphenols (Catechins)

These anti-oxidants are responsible in eliminating toxic waste products from the body, such as free radicals and other acidic products. They prevent damage to your body cells. Catechins can decrease plasma triglyceride levels as well. Triglyceride elevation can lead to cardiac conditions.

The polyphenols (flavonoids, flavanols and phenolic acid) have an anti-inflammatory action in the body aside from being an anti-oxidant too; thus it prevents proliferation of abnormal cells. Reportedly, it can help cure cancer. Scientists are still finding ways to permanently cure cancer. If researchers conduct an extensive study of green tea, perhaps by 2025, the FDA would approve of its use.

2. Caffeine

The caffeine in green tea increases the secretion of catecholamine. Thus green tea has the ability to increase the secretion of dopamine and norepinephrine. These are the hormones that are secreted more during emergency situations to keep the mind alert. When your mind is alert, your cognitive abilities also tend to sharpen. However, the effect of the caffeine contained in green tea is milder than that in coffee.

3. Amino Acid

Amino acids are the building blocks of the body. Without them, your body won’t develop as it should. The specific amino acid that green tea contains is L-theanine. When combined with caffeine, they produce a “boosting” effect that would promote mental alertness and brain activity.

4. Chlorophyll and Carotenoids

These are substances that help in keeping the gastrointestinal tract healthy. Carotenoids help in eye and skin health, and are rich with fibers and essential nutrients that the body needs.

5. EGCG (Epigallocatechin-3-Gallate)

This substance prevents the proliferation of abnormal cells. It’s a powerful component of green tea that helps the body in combating free radicals and oxidants. This action strengthens the immune system and prevents the risk of contracting communicable diseases.

6. Minerals

There are traces of several minerals in green tea: potassium, manganese, calcium, iron, phosphorus, fluorine and sodium, to name a few. These electrolytes are essential to various physiological processes in the body, such as blood clotting, transmission of nerve impulses, development of bone and teeth, water-electrolyte balance, and many more.

It seems green tea is the complete alternative liquid in maintaining health and fitness. Its health benefits are also varied and significant.

More Health Benefits of Green Tea

  1. Enhances Metabolism: Researches have concluded that green tea can enhance the metabolism of food, most especially fat. It also lowers blood glucose in Type II diabetic patients. If you’re a diabetic, you may want to include green tea in your daily diet.
  2. Helps prevent Cancer and Other Chronic Diseases: As mentioned earlier, green tea has been documented to help prevent cancer and some chronic diseases. This is because of the presence of a large amount of polyphenols. The polyphenols act as anti-oxidants, destroying abnormal cells in the body.
  3. Reduces the Risk of Stroke and Myocardial Infarction: Because of the polyphenols, green tea has been observed in clinical trials to reduce blood pressure, and thus reduces the risk of a stroke or a heart attack (myocardial infarction). It decreases glucose and fat and thus normalizes your BMI (Body Mass Index).
  4. Helps Prevent Parkinson’s and Alzheimer’s Diseases: A study was conducted on the neurological effects of green tea on both diseases and it has good results. However, further study that includes a broader number of respondents is recommended. It should also focus on the elderly, who are susceptible to these two diseases.

Now, let’s learn about the reasons why you should not be drinking green tea before bed. Based on the facts presented above, here are the reasons why:

Reasons Why You Should Not Be Drinking Green Tea before Bed


Green tea contains caffeine, and caffeine may keep you awake even if you’re in bed. If you intend to sleep, you may not be able to. Instead, you would be alert and your brain would be wide awake. Although the caffeine in green tea is not as potent as that contained in coffee, it’s still advisable to drink green tea in the morning after breakfast, or during anytime of the day, except before bedtime.


Your senses are heightened because of the ‘emergency’ hormones that would be activated by the green tea. So, if you fall asleep, you can be awakened even by slight noises. Your mind and body are awake; so, you would be sleeping restlessly. This will only stress you out.

Precautions in Drinking Green Tea

  • Overconsumption is harmful because of the presence of caffeine and aluminum. The polyphenol tends to react with iron too.
  • It’s not recommended for breastfeeding women.
  • It’s not recommended for patients with major cardiac illnesses.
  • It’s not recommended for patients with renal failure.


Aside from its numerous health benefits, green tea is an energy booster. Hence, it would keep you awake if you drink it before going to bed. Thus, drinking green tea before bed is not recommended. You have to include it in your daily drinks; however, because of its amazing health benefits.

Nevertheless, you have to take note that green tea taken in excess can be harmful to your body. One or two glasses a day is sufficient. Natural drinks are always the best because they have fewer side effects, and the health benefits outweigh the disadvantages. Just remember not to over do it.
