Establishing a dedicated and clutter-free study environment minimizes distractions, fueling better focus. Regular physical activity and hydration can boost energy levels, keeping the mind alert. Additionally, practicing mindfulness or meditation can help reduce anxiety and enhance focus, supporting sustained attention during extended study sessions.
