Green tea helps increase your energy levels due to the caffeine it contains.
Caffeine stimulates the central nervous system, inhibits the production of adenosine (which makes us sleepy) and increases a range of neurotransmitters such as dopamine and norepinephrine (1, 2).
Green tea helps to calm and relax your body. Inside green tea is an amino acid called L-theanine which is responsible for calming effects green tea has. According to research, L-theanine helps to increase GABA, a neurotransmitter which decreases stress and anxiety levels (3).
One clinical trial looking at 240 people showed that green tea caused a decrease in body weight and belly fat, primarily due to the caffeine and catechins green tea contains (4).
A literature review of the health benefits of green tea concluded that the antioxidants in green tea may be able to help reduce the risk of cancer in humans (5).
A review looking into the antiobesity effects of green tea also showed that compounds in green tea can help modify the appetite and help aid with weight loss (6).
The benefits of green tea far outweigh any risks, so drink it as you please. Keep in mind that green tea is relatively high in caffeine and so it’s best to avoid drinking large amounts of the beverage in the afternoon and evening.
Green tea may cause an upset stomach when you drink it on an empty stomach or when it is consumed in excess (7).
Green tea may decrease testosterone, which is the primary male sex hormone.
An in-virto study showed that the green tea catechins (EGCG and EC) inhibited the production of testosterone (8). Other studies on rats have confirmed similar results (9). It's important to note that these results are not done on humans.
Although green tea doesn't have as much caffeine as coffee, it still has around one-third the amount in an average cup. Caffeine is associated with a decrease in sleep quality and so limiting green tea intake is recommended if you struggle to sleep (10).
Green tea is generally seen as being safe. However, as with any substance you consume, how green tea affects you will depend on your own physiology.
Caffeine may increase acidity in your stomach and cause stomach issues thus if you notice that you have an upset stomach it may be a good idea to cut back on caffeine.
