Summary
In this Huberman Lab Essentials episode, I explain how salt (sodium) affects mental and physical performance, as well as cellular health. I describe how the brain monitors sodium levels to regulate thirst and fluid balance, and why salt needs can vary depending on activity level, stress, blood pressure, and diet. I also explain how to determine the right sodium intake for your individual needs and discuss why some people may benefit from increasing salt and other electrolytes.
