Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Salt (including sea salt) has a long history of use in traditional remedies for hangovers. This practice is rooted in the belief that salt helps restore electrolytes lost during alcohol consumption and subsequent dehydration. Many traditional hangover cures, such as salty soups, broths, or drinks like "salty lemonade," have been used across various cultures. However, the scientific evidence specifically supporting salt's effectiveness in treating hangovers is very limited. While alcohol can cause dehydration and loss of electrolytes, and salt can help replenish sodium, most hangover symptoms are not solely caused by sodium depletion. Scientific studies on hangover treatments generally focus on rehydration with water or oral rehydration solutions containing a balance of electrolytes (not just sodium). There is no robust clinical evidence that adding salt alone significantly alleviates hangover symptoms. Therefore, while salt plays a role in traditional remedies and may contribute to rehydration as part of a balanced electrolyte solution, its use as a standalone remedy for hangovers is not well-supported by scientific research.
