New research reckons that having a cup of tea does calm you down if you've been facing a difficult situation.

A team from University College London (UCL) has been testing the effects of a nice cuppa on a team of students.

Professor Andrew Steptoe told the BBC:

"Although it does not appear to reduce the actual levels of stress we experience, tea does seem to have a greater effect in bringing stress hormone levels back to normal."

So if you sell tea, get ready for the rush!
