Abstract:
The Experimental Design aims to study effect of drinking green tea to changing in brainwave (Delta, Theta, Alpha, Beta, Gamma) and the changes in stress level after drinking green tea. The participants were 12 Thai healthy age range between 21-55 years old, assessment stress by Thai Stress Test. Cllection data, PS Tower 25Fl, Asoke road, Sukhumvit 21, Klong Toey Nua, Wattana, Bangkok.
The result of stress level scores showed that before drinking green tea 37.00 SD 6.715, after drinking green tea 30.58 SD 7.645, t=3.434 and green tea reduce level stress significant p=0.006. Comparative effects of brainwaves during before and after drinking green tea, Alpha and Gamma brainwaves were related to stress reduction.
The benefit of this study is to provide the guideline for planning and campaigning green tea consumption for the purpose of stress reduction and activation of brain activity resulting in relaxation, stress reduction improved brain function performance, Analysis statistic by Paired sample T-test and sLORETA Program.
