Symptoms of low sodium levels?

Low sodium levels, also known as hyponatremia, can cause several symptoms impacting both mental and physical health. According to Andrew Huberman:

1. Stress and Anxiety: Low dietary sodium can exacerbate stress and anxiety. This could be due to the role of the adrenal glands in regulating salt preference through glucocorticoids like aldosterone, which affects fluid balance and can impact mental health 1.

2. Mental and Physical Stamina: Sodium is crucial for maintaining focus, mental clarity, and physical stamina. Insufficient sodium intake may significantly affect these areas, particularly in individuals who are health-conscious, train regularly, and consume minimally processed foods 2.

3. Neurological Function: Severe low sodium can impair neuron function, potentially inhibiting their ability to fire action potentials, leading to serious neurological issues 3.

Knowing the wide range of symptoms associated with low sodium is key to managing health effectively, particularly in contexts of stress, diet, and overall fluid balance. Always consider consulting with a healthcare provider if you are experiencing these symptoms or suspect a sodium imbalance.
