Can a Hot Tub make you Dehydrated? Read on…

Getting in a hot tub means experiencing relaxation, but a lot of people noticed that they often get lightheaded or thirsty when they get out.

A hot tub can lead to dehydration and sweating, but it’s even worse if you are not drinking enough water, have high alcohol consumption, or soak longer than 20 minutes.

However, it gets more in-depth than that, so let’s dive in to learn more.

Can a Hot Tub Cause Dehydration?

The hot tub itself will not cause dehydration, but combine that with other factors like soaking longer than 20 minutes at 40°C, not drinking enough water, or having too much alcohol can cause dehydration.

The United States Geological Survey claims that an adult female needs 2.2 litres per day, while an adult male needs 3 litres of water a day. All of this means that not drinking enough water before you get in a hot tub is the culprit of dehydration. The hot water simply accelerates the symptoms of dehydration.

The most significant factors that impacts dehydration are:

  • Excess urination
  • High fever
  • Diarrhoea or vomiting
  • Excess sweat

Symptoms of dehydration after hanging out in the hot tub:

  • Dizziness
  • Excess thirst
  • Sleepy
  • Lightheaded

If you experience these symptoms, get out of the hot tub immediately and slowly drink some water until the symptoms are gone.

Here are other symptoms to look out for:

  • Frequent thirst
  • Sleepy
  • Dizziness
  • Unable to urinate
  • Dark urine

For young children, here are common symptoms:

  • Irritability
  • Dry mouth
  • Lack of tears when crying
  • Lack of wet diapers for a few hours

When in doubt, talk to a doctor ASAP; after all, it’s better to be safe than sorry.

Don’t forget to take a break and get out of the hot tub after 15-20 minutes of soaking.

Is it Safe to Drink Alcohol in a Hot Tub?

Alcohol and hot temperature combined can significantly dilate the blood vessels, leading to dizziness, disorientation, and dehydration.

Therefore, alcohol can possibly cause dehydration, so it’s best to limit to one drink in the hot tub.

Other Issues From Drinking Alcohol in The hot tub:

Cuts…

Broken glass from beer bottles can accidentally get broken. It can be difficult to see and remove all the glasses safely without getting cut.

Lack of Coordination…

Be careful when entering and leaving the tub because alcohol can affect balance and coordination. The last thing you want is to slip and fall; how embarrassing is that.

Does the high temperature of a hot tub impact dehydration?

The higher the water temperature and the longer you soak can increase your chance of dehydration. That means you should never exceed 20 minutes of soaking time, especially if the temperature is at 104° F.

Excess sweating is the biggest factor that a hot tub can impact dehydration, which means the higher you set the thermostat to, the more you’ll sweat.

What is the best temperature for a hot tub?

The US Consumer Products Safety Commission recommends not to exceed 104°. If you are pregnant, then don’t exceed 100 degrees F.

Is it safe to stay in a hot tub for too long?

Never exceed 20 minutes of soak time, especially if the temperature at 104° F. It’s a good idea to leave the hot tub after about 15 minutes. Don’t forget to drink plenty of water.

Can I Use The Hot Tub Alone

You should never use the hot tub alone, mainly because the symptoms of dehydration can leave you vulnerable to drowning.

Overview

The great part about a hot tub is that it can alleviate sore and tired muscles.

However, dehydration depends on:

  • how much water we’ve consumed the whole day
  • what temp we have our hot tub on
  • The amount of alcohol we have

So the overall question is, can your hot tub dehydrate you?

The answer is yes, especially if you are exposed to high temperatures for a long period, along with other health issues. Because of that, it’s highly recommended NOT to set your hot tub temperature too high.

It’s also advisable to take a break after 10-15 minutes of soaking and to limit yourself to only one alcoholic drink in the hot tub.

With the proper safety precaution, you are set to have some fun.
