Abstract
Tea
has historically been associated with mood benefits. Nevertheless, few
studies have empirically investigated mood changes after tea
consumption. We explored immediate effects of a single cup of tea up to
an hour post-consumption on self-reported valence, arousal, discrete
emotions, and implicit measures of mood. In a parallel group design, 153
participants received a cup of tea or placebo tea, or a glass of water.
Immediately (i.e. 5 min) after consumption, tea increased valence but
reduced arousal, as compared to the placebo. There were no differences
at later time points. Discrete emotions did not differ significantly
between conditions, immediately or over time. Water consumption
increased implicit positivity as compared to placebo. Finally,
consumption of tea and water resulted in higher interest in activities
overall and in specific activity types compared to placebo. The present
study shows that effects of a single cup of tea may be limited to an
immediate increase in pleasure and decrease in arousal, which can
increase interest in activities. Differences between tea and water were
not significant, while differences between water and placebo on implicit
measures were unexpected. More servings over a longer time may be
required to evoke tea's arousing effects and appropriate tea consumption
settings may evoke more enduring valence effects.
