Sweat it Out: The Importance of Hydration After IR Sauna Use

Are you wondering how much water you should drink after using an infrared sauna? At Salted Peace, we understand the importance of hydration, and we're here to help you find the right balance.

As a general rule, you should drink at least 16-20 ounces (473-591 ml) of water after an infrared sauna session. In total, aim to consume half your body weight (in pounds) in ounces of water throughout the day to stay adequately hydrated.

We have some essential tips to share to optimize your hydration after enjoying the benefits of an infrared (IR) sauna. Keep reading to learn more.

Why Hydration is Crucial After an Infrared Sauna Session

Infrared saunas are known for their numerous health benefits, including detoxification, muscle relaxation, and improved circulation. However, the increased sweating during an IR sauna session can lead to dehydration if proper hydration is not maintained. Here's why staying hydrated is so important after using an IR sauna:

  • Fluid Loss: Sweating is a natural process that helps regulate body temperature and remove toxins. In an IR sauna, your body's core temperature increases, causing you to sweat more than usual. On average, a person can lose between 0.5 to 1.5 liters of fluid per hour in a sauna. This significant fluid loss can lead to dehydration if not replenished.

  • Detoxification: One of the primary purposes of using an IR sauna is detoxification. When you sweat, your body eliminates toxins and impurities. Drinking water after a session helps flush out these toxins more efficiently, enhancing the detoxification process.

  • Temperature Regulation: IR saunas increase your body's core temperature, which can cause an imbalance in your body's thermoregulation if proper hydration isn't maintained. Drinking water after a session helps restore this balance and prevent overheating.

  • Preventing Adverse Effects: Dehydration can lead to various symptoms, such as dizziness, headaches, fatigue, and muscle cramps. Staying hydrated ensures that you can enjoy the benefits of an IR sauna without experiencing these negative side effects.

  • Optimal Recovery: Adequate hydration is essential for muscle recovery and relaxation after a sauna session. Water helps transport nutrients to the cells, remove waste products, and support overall cellular function. Drinking enough water post-sauna promotes optimal recovery and relaxation.

Maintaining proper hydration after an IR sauna session is crucial for optimizing the numerous health benefits, preventing negative side effects, and supporting your body's overall well-being. Don't forget to drink at least 16-20 ounces of water after your session and continue to stay hydrated throughout the day.

Signs of Dehydration to Watch Out For

Dehydration occurs when your body loses more fluids than it takes in, and it's essential to be aware of the signs, especially after an IR sauna session. Here are some common symptoms of dehydration to watch out for:

  • Thirst: While thirst is an obvious indicator of dehydration, it's essential to note that you should drink water before you feel thirsty. Thirst is often a late sign of dehydration, so staying proactive with your hydration is key.

  • Dark Yellow Urine: Monitoring the color of your urine is an effective way to gauge your hydration levels. If your urine is a dark yellow color, it could indicate dehydration. Ideally, you should aim for pale yellow or clear urine as a sign of proper hydration.

  • Dry Mouth and Lips: Dehydration can cause a decrease in saliva production, leading to a dry mouth and chapped lips. These are early signs that your body needs more water.

  • Fatigue and Dizziness: When your body is dehydrated, it can lead to a lack of energy and feelings of dizziness, as your body struggles to maintain its normal functions.

  • Headaches: Dehydration can cause headaches due to the reduced blood flow to the brain and the tightening of blood vessels as your body tries to maintain its fluid balance.

  • Muscle Cramps: Electrolyte imbalances caused by dehydration can lead to muscle cramps and spasms, especially after engaging in physical activities like using an IR sauna.

  • Decreased Sweat and Tear Production: If you notice that you're not sweating as much as usual or your eyes are not producing tears, it could be a sign of severe dehydration.

  • Rapid Heart Rate and Breathing: Dehydration can cause your heart rate and breathing to increase as your body attempts to compensate for the lack of fluids.

If you experience any of these signs after an IR sauna session or at any other time, it's essential to drink water immediately to replenish your fluids. Remember to listen to your body and respond accordingly to maintain optimal hydration and overall health.

The Role of Electrolytes in Hydration

Electrolytes are essential minerals found in your body that play a crucial role in maintaining hydration and overall health. They are responsible for various functions, such as regulating fluid balance, nerve signaling, and muscle function. The primary electrolytes include sodium, potassium, magnesium, calcium, chloride, and bicarbonate. Here's a closer look at the role of electrolytes in hydration:

  • Fluid Balance: Electrolytes help regulate the balance of fluids in your body. They control the movement of water in and out of cells, which is crucial for maintaining proper hydration levels. Sodium and potassium, in particular, play a significant role in this process.

  • Nerve Signaling: Electrolytes are vital for proper nerve function, as they generate electrical impulses that allow for communication between nerve cells. Sodium and potassium are especially important in maintaining the electrical gradients across cell membranes, facilitating nerve impulse transmission.

  • Muscle Function: Electrolytes, such as calcium and magnesium, are essential for muscle contraction and relaxation. They help control the flow of ions across muscle cell membranes, enabling proper muscle function and preventing cramps or spasms.

  • Acid-Base Balance: Electrolytes like bicarbonate help maintain the acid-base balance in your body, which is necessary for optimal cellular function and overall health. An imbalance in your body's pH can lead to various health issues.

  • Blood Pressure Regulation: Sodium and potassium play a key role in regulating blood pressure by controlling the balance of fluids in your body. Maintaining proper electrolyte levels can help prevent high or low blood pressure, which can have severe consequences for your health.

When you sweat, such as during an IR sauna session, you lose not only water but also electrolytes. To maintain proper hydration and prevent dehydration, it's essential to replenish both water and electrolytes. Drinking water with a pinch of salt or consuming electrolyte-rich beverages, such as sports drinks or coconut water, can help maintain the right balance of electrolytes in your body after an IR sauna session or any other activities that cause significant fluid and electrolyte loss.

How to Monitor Your Hydration Levels Effectively

Monitoring your hydration levels effectively is essential to maintaining optimal health, especially after activities that cause fluid loss, such as sweating from an IR sauna session. One simple way to gauge your hydration status is by observing the color of your urine. Properly hydrated individuals will have pale yellow or clear urine, while dark yellow or amber-colored urine is a sign of dehydration. Monitoring your urine color throughout the day can provide a quick and easy way to ensure you're staying well-hydrated.

Another method to monitor your hydration levels is by paying attention to your body's signals, such as thirst, dry mouth, or fatigue. However, it's important to remember that thirst can be a late sign of dehydration, so it's better to drink water before feeling thirsty. Additionally, take note of any changes in your sweat output or the presence of muscle cramps, as these could also indicate dehydration. By keeping a close eye on these factors and responding to your body's needs, you can effectively maintain proper hydration levels and promote overall health.

Maximizing the Health Benefits of Infrared Saunas

To get the most out of your IR sauna sessions, it's important to implement a few key strategies. First, start with a consistent sauna routine. Regular sessions, ideally 3 to 4 times a week, can help you experience the full range of health benefits, such as detoxification, improved circulation, and reduced inflammation. However, the frequency may vary depending on individual preferences and health conditions, so it's crucial to listen to your body and adjust your routine accordingly.

Next, ensure that you properly preheat your IR sauna to the recommended temperature, which is usually between 110°F to 130°F (43°C to 54°C). By doing so, you'll allow the infrared heat to penetrate your body more effectively, enhancing the detoxification process and promoting relaxation. During your session, aim for a duration of 20 to 45 minutes, depending on your tolerance and experience level. It's essential to gradually build up the duration and intensity of your sessions over time to avoid overexertion.

Lastly, to maximize the health benefits of IR saunas, it's crucial to maintain proper hydration and electrolyte balance before, during, and after your sessions. As discussed earlier, drink at least 16-20 ounces of water after your session, and ensure you're consuming enough electrolytes throughout the day. By following these guidelines, you can effectively enhance the health benefits of IR saunas and support your overall well-being.


Staying hydrated after using an IR sauna is essential to ensure you reap the full benefits of your sessions while avoiding any negative side effects. Remember to drink at least 16-20 ounces of water after your session and maintain proper hydration throughout the day. Keep an eye on the signs of dehydration, such as dark yellow urine, dry mouth, or muscle cramps, and replenish both water and electrolytes as needed. By effectively monitoring your hydration levels and following the tips provided to maximize the health benefits of IR saunas, you can enjoy a revitalizing experience that supports your overall well-being.
