Green tea is a highly consumed beverage after water, which has led to numerous studies that explain its health benefits. It also has a pleasant taste and a calming effect that is incomparable to the effect of caffeine.
Apart from the change in lifestyle and diet, green tea also contributes to a decrease in symptoms of depression. Furthermore, people who drink about four cups of green tea every day showing fewer symptoms as opposed to their counterparts who drink less.
Consequently, green tea is used as Chinese medicine to treat depression and manage anxiety in patients. The presence of a distinctive predominant amino acid known as L-theanine found in tea plants causes the green tea calming effect.
L-theanine helps to relax the mind and body, therefore, reducing stress, improving sleep, promoting concentration and alertness as well as making someone feel calm. The amino acid also added to other foods and beverages.
Green Tea’s Physiological Effects
The effects of the caffeine contained in tea may contradict the green tea calming effect. However, L-theanine acts against the effects of caffeine in stimulating the nervous system hence creating a relaxation sense in less than one hour after ingestion.
The amino acid is actively involved in the creation of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter that raises the levels of serotonin and dopamine neurotransmitters, resulting in the production of the ultimate relaxation effect. L-theanine also stimulates the production of alpha brain waves, which causes deep relaxing and alertness of the mind close to the feeling attained on meditation.
The Alpha Brain Stimulation
Weak electrical impulses known as brain waves measurable on the head’s surface are emitted by the brain whose frequency corresponds to mental activities and states of the individual. The waves are in the delta, theta, alpha, and beta categories associated with a different mental state each.
The alpha brain waves present in wakefulness and involuntary alertness are the relaxation index because they respond to L-theanine within forty minutes of consumption, rising from the back of the head to the top.
The amount of time between drinking green tea and the reaction of the alpha waves varies from the amount of L-theanine present. Meaning the more green tea consumed, the quicker they achieve the calming effect.
Green Tea Calming Effect And Stress Management
Conditions such as anxiety and stress can mess with hormonal balancing leading to decreased performance and besides, they can impair the immune system causing depression. As may be the option of many people suffering from depression, anti-anxiety drugs can leave the victim sedated unlike using L-theanine in green tea, which is harmless and natural.
L-theanine does not affect the sleep-stimulating theta brain waves, making green tea the perfect solution for managing stress and anxiety as it elevates mood and leaves one feeling better.
The green tea calming effect has stimulated ongoing research as to whether L-theanine can treat Pre-Menstrual Syndrome and high blood pressure as well as act as a sharpener for mental concentration in children. Consumers should substitute soft drinks, coffee, and teas with high caffeine content with green tea as it helps in reducing caffeine dependency.
