Caffeine triggers the release of dopamine, ne, a chemical that stimulates alertness. A moderate amount can perk k you up, keep you sharp, and improve your mental performance for up to 45 minutes. But limit your daily coffee to one or two cups, as too much caffeine can cause jitters and interrupt your nightly sleep, which is key to keeping you alert the next day.
Instead of coffee, you can add a drop of peppermint essential oil to a cup of water for a quick pick-me-up!
