Feel a bit scatterbrained now and then? Make yourself a big jug of sun tea.

Not for the caffeine, but for one heck of a potent compound that could fine-tune your focus. It’s theanine.

Your Brain on Theanine
When people in a study consumed theanine (an amino acid) and then performed a challenging mental task that required both looking and listening skills, their brains became quite active. Specifically, the right parietooccipital cortex lit up. That's a part of the brain's circuit system tied to attention span. So if you feel more alert and focused after a tea break, it’s no wonder!
