Purpose, evidence and practical considerations.
Used as a comfort or recovery ritual. The available reference does not establish a therapeutic salt concentration or a magnesium-replacement schedule.
An Epsom-salt bath is a reported comfort practice. Available evidence does not establish effective magnesium replacement or toxin removal through the skin, and oral-magnesium studies cannot be applied to bathwater.
Confidence: weak
Hot baths can cause dizziness or overheating, and bath products can irritate skin. Do not swallow bath salts; avoid use on irritated skin and use particular care with reduced sensation or mobility.
Epsom salt is magnesium sulfate dissolved in bathwater. The bath is a topical bathing practice, not an oral magnesium supplement. Comfort from bathing should be kept separate from claims about correcting a nutrient deficiency.
