In this episode, I provide a list of behavioral, nutritional, and supplement-based tools you can use to improve your ability to get into a focused state to do mental or physical work. I explain science-supported strategies for transitioning into focus, maintaining focus during the work bout, and exiting the focus session, which is also critical, including decompression/defocusing tools. I explain when and how to use: binaural beats, caffeine, deliberate cold exposure, the pros and cons of working in fasted vs. fed states, and supplements and foods that enhance dopamine, epinephrine (i.e., adrenaline) and acetylcholine to promote optimal focus. Also, I explain how short behavioral practices, such as meditation and visual gaze training, will benefit your ability to focus over the long term. As deep focus is crucial to significantly improve cognitive or physical performance in any realm, this episode should be useful to anyone. By the end, you’ll have an essential toolkit of science-supported, low- to zero-cost focus and concentration strategies to select from that can be tailored to your physical and mental performance needs.
