So, clearly, we are very invested in the hot material - such as tea-growing new Starbucks - but what we invest in? Further research on the relationship between nutrition and the brain helps explain why tea time is an essential part of the day - for the components of tea help to be more alert, relaxed and healthier in the long term.
The exact amount of stimulation
As you have experienced first hand, caffeine has important effects on people, the most famous acting as a stimulant and reduce drowsiness.
As University of Chicago behavioral pharmacologist said Emma Childs, caffeine increases alertness, because it prevents adenosine sedative to work at the reception.
"Adenosine has sedative effects," she said, "so by blocking the effects of adenosine, is trying to increase the central stimulation. Really increase the activity of the central nervous system."
Thus, drinks containing caffeine, such as tea give us more energy, because we block the signal to our brain that we are tired. But do not think for the rest of caffeine: Caffeine makes you less tired as an afternoon nap or an extra hour of sleep could, but will not give the depth of the restoration and consolidation of the memory that the sleep helps.
The exact amount of relaxation
Beyond caffeine, tea has another killer app, and it applies only to the sheet: theanine, an amino acid present in black and green tea acid, especially matcha, gyokuro anji bai cha and varieties . A review of the research suggests that theanine reduces anxiety and calm us, increasing the number of inhibitory neurotransmitters (balance our moods out) and modulates serotonin and dopamine (which is good for us).
Huffington Post writer and naturopathic doctor Natasha Turner captures the causality:
Theanine is by increasing the production of GABA in the brain. As the effects of the way of meditation, but also stimulates alpha brain waves that are associated with deep states of relaxation and improved mental clarity. L-Theanine may improve learning, attention and feelings of pleasure too. These effects are probably due to the impulse of natural dopamine caused by L-theanine. If you're wondering how something with caffeine can actually relax, L-theanine balance the stimulating effects of caffeine so stay alert without feeling jittery.
AND REMEMBER THE OXIDATION
Tea is full of antioxidants that thearubigins, epicatechin and catechin, which beyond being fun to say, have powerfully excellent results: they protect our cells against free radicals, thereby protecting against the formation of blood clots , cancer, or hardening of the arteries. In addition, research suggests that regular tea drinkers have a lower risk of heart disease and stroke, and reduce cholesterol.
In other words, you do not need to be a tasseographist knows that drinking tea predicts a healthy and productive future.
