Improves Brain Health
Drinking green tea will not only stop you from falling asleep, it can also increase your intelligence.The most important ingredient is caffeine, which is a known stimulant.It doesn’t hold as much as coffee, but enough to produce a response without making you all “jittery”, a feeling associated with too much caffeine.Green tea even slows the deterioration caused by Alzheimer’s and Parkinson’s, due to the bioactive compounds present in green tea that can have several protective effects on neurons.
Reduces Bad Cholesterol
Green tea reduces bad cholesterol in the blood and improves the ratio of good cholesterol to bad cholesterol. Studies regarding the effect of green tea consumption on cholesterol levels suggest that it lowers the level of low-density lipoprotein (LDL) cholesterol, the “bad” cholesterol.At the same time, it helps raise the level of high-density lipoprotein (HDL), which is considered “good.”
Prevents tooth decay
A small study from 2014 looked at how effective a green tea mouthwash was in preventing tooth decay compared with the more commonly used antibacterial mouthwash chlorhexidine. The results suggested they were equally effective, though green tea mouthwash has the added practical advantage of being cheaper.
Theanine is an amino acid naturally found in tea leaves. It is this substance that is thought to provide a relaxing and tranquilizing effect and be a great benefit to tea drinkers.
Lowers Blood Sugar Levels

The compounds polyphenols and polysaccharides present in green tea can be useful for both types of diabetes.One study in Japanese individuals found that those who drank mostly green tea had a 42% lower risk of developing type II diabetes.

Plus, green tea has a component called epigallocatechin gallate (EGCG) that promotes hair growth by stimulating hair cells.
Green tea can apparently also help with wrinkles and the signs of aging, This is because of their antioxidant and anti-inflammatory activities.
Some studies show that they can kill bacteria and inhibit viruses like the influenza virus, potentially lowering your risk of infections.
