Why Does Tea Make Me Nauseous? See Reasons Here

You get nauseous from drinking tea as a result of the tannins present in the leaves. These tannins are the cause of the dry, bitter taste you get from tea and can greatly irritate your digestive tissue. 

Digestive irritation as a result of tannins present in tea can result in unpleasant symptoms like nausea, vomiting, and stomach ache. However, the amount of tea required to cause these symptoms may vary from one person to another. 

This article helps you understand how tea can make you nauseous, and what you can do to suppress or relieve the symptoms. 

What causes nausea after drinking tea?

Nausea occurs after drinking tea as a result of the rise in stomach acid due to the tannins. This is especially true when it comes to herbal tea like green tea. The rise in stomach acid can then lead to constipation, nausea, and stomach.

Why is there tannin in tea?

Tannin is a naturally occurring component in tea, to begin with, and is quite concentrated in green and black tea. It is also responsible for that dry bitter taste you experience when you drink tea. Also, tannins are exceptionally useful when it comes to killing bacteria. 

There is no easy way to cut back on the tannins present in tea. As long as you brew your tea for longer than two minutes with high heat, tannins will surely seep into the brew from the tea leaves. 

Also, note that the more tea leaves you use in brewing your tea, the more potent the tannins will be in your tea. Taking that many tannins can lead to nausea. To avoid that much concentration of tannins, try brewing your tea with low heat for a short period of time.

What can you do to avoid or treat nausea when drinking tea?

To reduce the negative effects of tannin when you drink tea such as nausea or stomach ache, try adding some milk or honey. This blends with tannin and lowers the possibility of it inducing nausea. 

Another way to avoid the feeling of nausea when drinking tea is by doing so after eating and not on an empty stomach. However, if you haven’t eaten beforehand and would love to have some tea, try taking it with some biscuits.

If you have done all these and still feel nauseous, here are some quick remedies you can employ to feel better;

  1. Drink anything with ginger or chew the ginger root as it helps with nausea. 
  2. Eat something starchy like rice or bread. 
  3. Use spices like cinnamon and cumin extract
  4. Get your breathing under control
  5. Drink carbonated beverages or water
  6. Inhale some peppermint.
  7. Take them with snacks like biscuits
