Your Brain on Coffee: How Caffeine Affects Brain Chemistry

In your love affair with coffee, have you ever struggled with a pesky caffeine crash mid-afternoon? For most of us, this mid-afternoon slump is the perfect time to reach for yet another cup of Joe to keep energy levels high so that we can make it through the rest of the workday.

Although coffee has been proven to be a modern-day elixir with a long list of health benefits, that still doesn’t answer the question of how caffeine affects your brain day in and day out.

Caffeine in the US and Beyond

Today, up to 90% of Americans drink some form of caffeine each day. Roughly 50% of us drink up to 300 mg of caffeine daily, making it the most popular drug of choice in the US.
