Swap Caffeine for Cardio
If you rely on triple lattes to pay attention, you'll likely find it harder to focus when you're not buzzed. "Your brain will begin to operate as though it requires caffeine to be alert," explains Coates. A more effective stimulant: exercise. Physical activity has been shown to sharpen focus, in people with ADHD and without, possibly because it can help trigger the release of chemicals in the brain that are thought to affect learning and memory. One report from the University of Illinois at Urbana-Champaign suggests that aerobic exercise in particular may improve immediate and long-term functioning in regions of the brain relating to attention.
