Why should we drink salt water in the morning?

Drinking salt water in the morning, especially when fasting, can help manage blood glucose levels and enhance mental and physical states. Andrew Huberman explains that neurons require the electrolytes sodium and potassium for proper chemical and electrical signaling. Ingesting salt can offset feelings of lightheadedness and shakiness caused by slightly low blood sugar, which many people experience during intermittent fasting. Additionally, the consumption of caffeine can cause the excretion of sodium along with water, further justifying the need for replenishing salt levels. Overall, a small pinch of salt in water can stabilize blood volume, and this practice is found beneficial to mental clarity and reducing 'hunger jitters' until the next meal. Huberman emphasizes that this practice helps maintain alertness, and manage both mental and physical states efficiently during fasting or daily activities 1 2.
