hoe to increase cognitive function and focus

Cognitive function and focus can be supported with daily meditation, moderate exercise before demanding work, and—optionally—carefully chosen supplements or brief cold exposure.

1. Alpha-GPC: Huberman describes 300–600 mg about 10–20 minutes before focused work as a possible acute focus aid. He also notes a potential cardiovascular concern with chronic use and says he pairs it with 600 mg garlic; these are his personal practices, not a guarantee of safety. 1
2. Creatine monohydrate: 5 g daily is described as potentially supporting brain function and prefrontal networks involved in concentration; the time of day is not considered important. 2
3. Mindfulness meditation: Try a daily 13-minute practice: sit or lie down, focus on your breathing, and gently return attention when it wanders. The cited study found improvements in focus and other cognitive performance after daily practice over eight weeks. 3
4. Cold exposure: An uncomfortably cold but safe shower or immersion for 1–5 minutes may raise epinephrine and dopamine and help focus. 4
5. Moderate exercise: About 15 minutes of moderate exercise before cognitive work may support visual attention, perceptual speed, and working memory. 5
