This just might be the perfect excuse to keep some sweets on your desk (as long as you don’t go overboard, that is!). Compounds in cocoa called flavanols produce a surge in blood flow to the brain when you take that nibble of dark chocolate. That in turn helps you feel awake and alert and more able to easily conquer difficult tasks, according to a small British study.
Just sniffing the stuff can stimulate alertness. Eat an orange, and you also benefit from all that vitamin C, too.
Okay, so it’s not a food. But! Just about every system in the body suffers when we’re dehydrated, including the brain. Research shows that not sipping enough H2O throughout the day detracts from your focus and short-term memory, according to Psychology Today. Keep a reusable bottle or cup on your desk to remind you to drink — and you’ll get the added benefit of some extra steps around the office when it’s time for a refill.
