Stimulants‌ ‌In‌ ‌Tea:

The stimulants in tea are caffeine, theobromine, theophylline, and L-theanine. Each of them provides unique benefits for the body but as mentioned earlier, can produce unwanted effects in the body if not had in moderation. So let us know more about them in detail then. 

  • Caffeine
Stimulants‌ ‌In‌ ‌Tea

Considered as one of the most potent stimulants found in tea, did you know caffeine is also the most psychoactive substance used worldwide? However, tea does not contain caffeine as much as coffee does. A cup of coffee has 150-300 mg of caffeine whereas a cup of tea only contains 20-60 mg of caffeine. 

Benefits 

  1. Caffeine stimulates the central nervous system and helps in eradicating drowsiness. Caffeine helps in inhibiting the adenosine neurotransmitter which when built up in the body increases the sleep pressure that makes you drowsy and lethargic. Caffeine helps you in reversing the effect. 
  2. Improves short term memory and enhances reaction time. 
  3. Helps in reducing the risk of type 2 diabetes, Parkinson’s disease, and several liver ailments including liver cancer. 

Side effects

  1. Boosts blood pressure

  • Theobromine

Theobromine belongs to a class of organic compounds known as the xanthines. These compounds can produce several physiological effects on the body but it was believed that since a cup of tea only provides a small amount of theobromine, the effect produced on the body is therefore negligible. However, with recent studies, people who have been consuming tea for a long time, certain effects produced due by theobromine can be easily noticed in them. 

Benefits

  1. Theobromine helps in lowering blood pressure. When people with high blood pressure regularly consume theobromine in the form of their tea, it was noticed that theobromine helped in regulating the blood pressures by widening the blood vessels. 
  2. Theobromine improves the cognitive function of the brain. It enhances performance in mental tasks and also ameliorates mental fatigue simultaneously.

‌stimulants‌ ‌present‌ ‌in‌ ‌tea

Theophylline, similar to theobromine, belongs to the class of xanthines. It can also produce several physiological effects in the body. Also, did you know that the caffeine we ingest gets converted into theophylline and theobromine after metabolism? So next time, limit your caffeine intake as you simultaneously increase the caffeine metabolites in your body too and these can create several effects in your body.

Seizures are a life-threatening condition. Therefore, if you notice symptoms like tremors, twitching, tense muscles,  trouble in talking, or confusion, contact your nearest hospital immediately.
