Beyond bathtime: here's how to use Epsom salts

Salt’s almost certainly got a place in your kitchen cupboard... but what if you want to shake things up? Epsom salt is the kind you’d add to a bath after a long day, and it’s definitely not for sprinkling into your dinner. But there’s more to it than just bathtime, so here are some other ways to use Epsom salt and add something extra to your routine...

Epsom salt is a naturally occurring salt made of magnesium sulphate – magnesium, oxygen and sulphur. It’s different to the salt you’d use in cooking as it's got a different chemical makeup, plus we wouldn't recommend eating it. It was discovered in 1618 in Epsom, Surrey – unsurprisingly where it gets its name.¹ Centuries later, it’s used as alternative care and relaxation. Epsom salt’s main appeal is its magnesium content: magnesium is an essential mineral and, in our diet, plays a role in processes from normal muscle function to electrolyte balance and the reduction of tiredness and fatigue.^2,3,4 That’s not to say it has all these benefits in our baths, though (more on that later).

Not sure what to do with that pack in your bathroom cupboard? Great news: it’s pretty versatile. You should follow the instructions on your individual bathing salts’ packaging but here are a few ideas to get you started...

There isn’t enough evidence to say for sure that Epsom salts are useful for improving skin health, increasing magnesium absorption in the body or having any physical effect on muscles. But many people find them a relaxing addition to a warm bath or foot soak. It might be that the routine of a pamper evening – the warm water, time alone and relaxing atmosphere – plays more of a role in your relaxation than the magnesium itself. But if you find that Epsom salts work for you and you enjoy using them, no problem.

Phew... after all that, you’re due a pamper night. The science on Epsom salts is still emerging, but if they leave you feeling more renewed, then we say go full steam ahead.
