How to Stay Hydrated in a Hot Tub

You might think that since you’re sitting in a tub of water, you wouldn’t get dehydrated while hot tubbing. However, any time you expel more water than you take in, you’re bound to get dehydrated. Even though you don’t realize it, the warm water in your spa makes you sweat just like you would if you were doing another activity in the same type of temperature. Staying hydrated in your hot tub is important and easy to do. Here’s Fronheiser Pools’ best tips on how to boost hydration during your spa soaks this year. 

Follow the Guidelines

Dehydration is a big reason that guidelines for hot tub use exist in the first place. Read your manual carefully, but in general stick to these rules to avoid dehydration:
  • Don’t soak too long (generally, adults should soak 15-30 minutes at a time)
  • Keep the water at 104℉ or below
  • Don’t indulge in a soak if you know you’re already dehydrated
  • Avoid alcohol
  • Stay hydrated

Keep in Mind Special Circumstances

That 15–30-minute soak in 104℉ water we recommended might work for most people most of the time but take note of things that could affect how quickly you dehydrate. Have you started taking a new prescription? Read the label and/or check with your doctor to make sure hot tubbing is still okay. Are you just coming from a harder, longer workout? You’ll probably already be somewhat dehydrated, and your core temperature will be higher, so give yourself some time to recover before climbing in for that soak you’re craving.  Also, remember that kids are more heat-sensitive (even teens) than adults. So, don’t let them soak as long. And for younger kids, turn the temperature down and don’t let them fully submerge in the water. Elderly hot tubbers should also take shorter soaks, at least to start up. Once they know they stay comfortable in the water, they can try out a longer 20-minute soak.

Stay Hydrated While Enjoying Your Hot Tub

Did you know that if you feel thirsty, you’re probably already dehydrated? That’s why we always recommend you drink a glass of water before you enter your hot tub, even if you don’t feel thirsty.  Then, while you’re soaking, keep hydrating. Not only is a drink while you’re in the spa good for you, but it can be an enjoyable part of the experience. Water is always a winner, but if you want to enjoy a special drink, try fruit juices, sparkling water, iced tea, or Agua Fresca.  One of the wonderful things about hot tubbing is that it offers many of the same benefits of mild exercise. It increases your circulation and blood flow, which is why soaking in a hot tub can improve your blood pressure and your cardiovascular health. You wouldn’t take a jog or do cardio at the gym without hydrating, would you? It’s the same in your hot tub! Just follow the tips above and be mindful of hydration, so you can safely reap all the hot tub benefits you’re after. Want some more tips to enjoy your hot tub to the max?
