Usually sweat losses, dehydration, stress, or a trained salty palate - and most people already eat too much sodium. A new intense craving with weakness, weight loss, and darkening skin needs adrenal testing.

Common questions
Why do I crave salt?
Salt cravings are common and usually have ordinary drivers. The everyday ones: sweating a lot - hard workouts, hot weather, a physical job - pulls sodium out and the body asks for it back; plain dehydration concentrates things and mimics the craving; stress and poor sleep push appetite toward salty, crunchy comfort food; and habit does the rest - salty snacks train the palate to want saltier food, a preference that resets downward within a few weeks of cutting back. Here is the context that matters: the CDC notes most Americans already consume more sodium than recommended - over 3,400 mg a day on average against a 2,300 mg guideline - and excess sodium drives blood pressure up. So feeding the craving freely is rarely the right call. Hydrate first, check whether the craving follows sweat, and swap the ritual snack for something less salted. The medical exceptions are rare but real: an intense new salt craving with weakness, weight loss, darkening skin, and low blood pressure is the classic Addison disease pattern - adrenal glands failing to hold onto salt - and it needs prompt testing. Salt craving with dizziness on standing also deserves a blood pressure and bloodwork look. Persistent, unusual cravings with other symptoms are worth mentioning to a doctor.
