Rating (out of 5): 2

Sea salt has been traditionally used in various cultures to address issues related to deficient perspiration, such as anhidrosis (lack of sweating). Historical records suggest that salt baths and salt scrubs were employed to stimulate the skin and purportedly encourage sweat production. The rationale is based on the idea that salt may help open pores or draw out impurities, thereby facilitating perspiration. Some traditional systems, such as certain schools of naturopathy and balneotherapy, have recommended saltwater immersion for skin and sweat-related conditions.

However, there is limited scientific evidence to support the direct use of sea salt for treating deficient perspiration. While adequate sodium intake is essential for normal sweat gland function—since sodium is a key electrolyte lost in sweat—topical or dietary sea salt is not specifically recognized as a treatment for anhidrosis or other conditions of deficient sweating in modern clinical practice. Most scientific literature focuses on hydration status, electrolyte balance, and underlying medical causes of reduced sweating rather than on salt as an active topical remedy. Therefore, the support for sea salt in this context mainly stems from traditional practices rather than robust scientific validation.
