The beginner’s guide to hydrotherapy

Published on 31 May 2018 - Last updated on 19 December 2025 by Beth Ryan

Who knew there was another way to bring the mermaid trend into your beauty regime? Hydrotherapy uses hot and cold water to quite literally wash away your aches and pains. From meditational floatation tanks to spa circuits with ice-cold plunge pools, here’s everything you never knew you need to know about this therapy.

  • 1 Its history is way more interesting than classes at school

    If you've ever spent a weekend in Bath, you'll already know people have been enjoying water-based spa treatments for thousands of years. The ancient Romans, Egyptians and Greeks were all big fans, but it really took off in the 19th century. When the first hydrotherapy centre opened in Malvern, the A-listers of the day flocked to it like an olde world version of Champneys.

  • 2 It's relaxing as well as therapeutic

    We could wax lyrical about the health benefits of hydrotherapy all day but, as anyone who's ever lounged in a jacuzzi can knows, it's a blissful way to unwind. As for that invigorating cold splash, it gets the adrenaline (and endorphins) pumping.

  • 3 Hot and cold do different things to your body

    While heat relaxes you by widening blood cells, a chilly blast makes you feel invigorated. Kind of like the cold version of a piping hot, strong espresso that gives you that Monday morning world domination feeling. OK, so maybe you feel more like that on Friday afternoon, but you get the idea.

  • 4 It coaxes injuries back to health

    If you've been hitting the gym a bit too hard – or you tripped up in your less-than-practical heels last Saturday night – gentle exercise in a hydrotherapy pool can help you recover. The warm water soothes aching joints while boosting blood flow, helping to bring extra oxygen and nutrients to injured muscles. It also helps to maintain your muscle tone, so you can pick back up pretty much straight where you left off. (We mean at the gym, rather than where you were at 1am on Saturday.)

    With Treatwell, you can book beauty online at all your favourite salons – simple, hassle-free, and you can do it on the go. Discover amazing spas in your area.
