Tea drinkers know that having a cup of tea makes you feel better. Now, science has caught-up. A new scientific study of black tea shows the tea can help you recover from stress more quickly.
Researchers found that black tea cut levels of cortisol, the stress hormone, in the blood. Consumption of black tea reduces stress levels quicker than drinking other beverages. The study was conducted by University College in London and published the study in the Journal of Psychopharmacology.
The 6-week study monitored 75 young men who regularly consumed tea. During the study, the men were separated into 2 groups: one groups consumed black tea while the other was given a caffeinated drink.
The 2 groups were given a series of challenges and the subjects stress levels were monitored. The challenges substantially increased blood pressure, heart rate and self-rated stress levels. But, 50 minutes after the challenges, stress levels in the tea drinking group dropped 47% and in the non tea-drinking group stress levels dropped 27%. Blood platelet activation, which is linked to blood clotting and the risk of heart attacks, was lower in tea drinkers. Also, the tea drinking group reported greater relaxation after the challenges.
Possible reasons for tea helping to reduce stress levels include the ingredients in tea such as catechins, polyphenols, flavonoids, and amino acids.
Science is finally catching-up with what tea drinkers already know. Make sure to consult your doctor for specific health information.
