He found that consuming water with a little bit of salt helped stabilize his blood sugar levels and the shakiness he experienced 2.
He also emphasizes the importance of hydration for mental performance. In his routine, he drinks at least 16 to 32 ounces of water with a bit of sea salt in the morning before starting any work, noting that neurons require sodium among other electrolytes to function effectively 3.
