Dot Emarat – Three other green tea stimulants without caffeine

Tea contains 4 substances that have stimulating and stimulating effects on the brain, the most famous of which is caffeine, a powerful stimulant Tea also contains two substances related to caffeine: theobromine and theophylline, as well as a unique amino acid called L-theanine, which has very exciting effects on the brain.

The different effects of tea and coffee
Speaking of the psychological effects of coffee and tea, both contain caffeine, and thus have a similar effect to the alarm on the brain, but the nature of these effects are very different, and in an interesting analogy about it, one looks like the effect of tea gently encouraged to do something to love grandmother, D after a military, after having studied tea and its effects on the mind, it turns out that tea contains less caffeine than coffee, but that it also contains three other stimulants that can have a synergistic effect

Caffeine
Materials are widely used in the world in terms of psychosocial effect, s Coffee, the main source of caffeine, is one of the largest sources of antioxidants in the world. Western food and its consumption has been associated with various health benefits . It tends to provide a moderate amount of caffeine, depending on the type of tea.

Caffeine stimulates the central nervous system, increases alertness and decreases drowsiness There are many theories about its functioning, and we intend to say that it inhibits the inhibitor of neurotransmitters What is called adenosine in some synapses In the brain, resulting in a stimulating effect, it is believed that adenosine increases in the brain throughout the day, resulting in some kind of 'pressure "the higher the rate of adenosine, the more likely sleep is and caffeine partially reflects this effect. Coffee and tea make tea contains much less than coffee, and that a strong cup of coffee can save between 100 and 300 mg of caffeine, while a cup of tea can only provide 20 at 60 mg.

In tea other than caffeine
1- Theophylline and theobromine
Theophylline and theobromine are two-sided Of these three stimulants found in green tea and other non-caffeinated teas , belong to a class of organic compounds called Xanthins, both of which have many physiological effects on the body, and theophylline relaxes the smooth muscles in the airways, facilitating breathing while stimulating the frequency and strength of muscle contractions cardiac and theobromine can also stimulate the heart, but have a moderate diuretic effect and improve blood flow in the body, causing a decrease in blood pressure, and cocoa beans are also a good source of both substances [19659007] The tea is very small Therefore, the net effect on the body can not be negligible, such as the metabolism of caffeine in the t heophylline and theobromine, so whenever we consume caffeine indirectly increases the levels of these metabolites, then theophylline and theobromine are organic compounds linked to caffeine.

2. L-Theanine "Psycho-amino acid and its unique properties"
This last is the most interesting of the four substances mentioned previously, they are a unique type of amino acid L-theanine, which is found mainly in m The caffeine, thiophenyl and thiopromine can enter the brain crossing the blood-brain barrier In humans, L-theanine increases the formation of brain waves called alpha waves, which are associated with relaxation. L-Theanine may affect neurotransmitters in the brain such as GABA and dopamine Some studies suggest that this substance, especially when it is associated with caffeine, may improve attention and brain function.

Bottom line
Green tea, the right alternative for those Who are allergic to large amounts of caffeine, because of L-theanine and its effects on alpha waves in the brain, tea can be a better choice for those who need to focus for long periods. Excessive sensations, like coffee, do not have the same stimulating effects as coffee, and in general I think tea and coffee have different advantages and disadvantages, so tea seems to be the best option for work on computer or study. This coffee is more suitable for physical activity such as aerobics.
