Black Tea Reduces Stress

Tea drinkers know that 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 group consumed black tea while the other was given a caffeinated drink.

The 2 groups were given a series of challenges and their 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% while stress levels in the non tea-drinking group dropped 27%.  Blood platelet activation, which is linked to blood clotting and risk of heart attacks, was lower in tea drinkers.   Also, the tea drinking group reported greater relaxation after the challenges.

A possible explanation for stress reduction is the ingredients in tea, which include 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.
