The stimulant we always address when we discuss coffee and tea is caffeine.
This may come as a surprise, but tea leaves actually contain more caffeine than coffee beans do.
Both can stimulate the heart, but also further affect the body in different ways.
Theobromine is the reason why tea can also act as a mild diuretic (viaHealthline).
The fourth stimulant, known as L-theanine, is seen to be the most interesting of the stimulants.
This stimulant has the unique ability to both enhance sleep in non-caffeinated teaandenhance cognitive skills in caffeinated varieties.
L-theanine can also help boost brain activity, helping with attention, focus, memory, and learning.
