Do Hot Tubs Dehydrate You?

You might have wondered if you can get dehydrated by soaking in a hot tub. The answer is: you can. The water in a hot tub is usually around 100 degrees, but it can reach 104 degrees. This heat can make your body sweat which can dehydrate you. However, as long as you follow some basic hot tub safety advice, there’s absolutely nothing to worry about.

The recommended advice is that you use the hot tub in 20-minute sessions, and never use it if you are on prescription medication, pregnant, or are under the influence of alcohol.

Symptoms of Dehydration

It is a good idea for you to be able to recognize the symptoms of dehydration in yourself and in other bathers. The first signs that you are beginning to get dehydrated are a dry mouth, dizziness, headache, and excessive thirst. If you feel these symptoms, or you notice another bather experiencing these symptoms, you should get out of the tub, and drink a glass of water.

Dehydration can become more serious if you try to ignore the initial warning signs. Moderate and severe dehydration can have symptoms like a rapid heartbeat, fainting, fever, and lethargy.

Tips for Staying Hydrated In Your Hot Tub

There are a few things you can do to keep yourself hydrated during your relaxation session in your hot tub.

Be Hydrated When You Get In The Tub

The best advice you can ever get is to be hydrated when you get into the tub. Drink a glass of water before you get into your hot tub.

If your tub is in direct sunlight, you might want to think about adding a large umbrella or wearing a sun hat for shade.

Stay Hydrated

It’s always a good idea to take a bottle of water into the tub with you. Keep it close to hand, and sip it while you relax. If you’re bathing with others, make sure everyone has a bottle of water with them.

If you’re not a huge fan of plain water, you can infuse it with fruit, such as lemon, lime, cucumber or berries. Fruit-infused water tastes delicious, so you’ll be more likely to drink it.

If you’re using the hot tub during winter, you’re probably going to want a warm drink rather than a cold one. Caffeinated drinks should be avoided, and instead, try herbal tea.

If you want snacks for you and your guests, look for hydrating snacks. Some fruits and vegetables have high water content, and nibbling on them can help keep you hydrated while you’re in your home spa. Try serving slices of cucumber, strawberries, or carrots.

Hot tubs are fun, but they can also offer you many other health benefits, from improving sleep to reducing stress. They’re also safe, and risk-free. Just make sure you follow the advice around staying hydrated and use your common sense.
