One of the common questions asked is whether eating before or after a sauna session is advisable. In this article, we will explore why eating before entering a sauna is generally not recommended, how long one should wait before entering the sauna after a meal, and what foods are ideal to consume before a sauna session.

Why should you not eat before the sauna?

Can You Do Sauna After Eating

Eating a heavy meal before entering a sauna is generally not recommended due to several reasons:

A sauna can disrupt digestion 

The high temperatures in the sauna cause an increase in blood flow to the skin, which can lead to reduced blood flow to the stomach and the digestive system. This can result in digestion-related discomfort such as nausea, bloating, and even indigestion. Additionally, the body’s temperature rises during a sauna session, and the digestive process also requires an increase in body temperature. Both of these processes simultaneously can strain the body and make it difficult to digest the meal properly.

Increase the risk of dehydration

Sauna sessions often induce sweating as a way to cool down the body. Sweating can lead to fluid loss, and if a person has recently consumed a large meal, it can increase the risk of dehydration. It is important to stay hydrated during a sauna session, and having a full stomach can complicate this process.

It can affect the overall sauna experience

When the body is focused on digesting a heavy meal, it may detract from the relaxation and detoxification benefits that a sauna session can provide. The heat from the sauna is meant to promote circulation, relax muscles, and release toxins through sweat. However, if the body is busy digesting food, it may not fully reap these benefits.

How long should you wait to enter the sauna after eating?

It is advisable to wait at least one to two hours before entering the sauna to ensure proper digestion. It is important to note that everyone’s digestive system works differently, so listening to your body and gauging how you feel before entering the sauna is key in determining the appropriate waiting time.

What to eat before sauna?

While it is best to avoid heavy meals before a sauna, it is still important to nourish your body with the appropriate foods to ensure you have enough energy for the session. Opt for light and easily digestible foods such as fruits, vegetables, salads, lean proteins, and whole grains. These foods provide a good balance of nutrients and won’t overload your digestive system. It is also a good idea to stay adequately hydrated by drinking water or herbal teas before entering the sauna.

Is it better to eat before or after the sauna?

Overall, it is generally better to eat after a sauna session rather than before. This allows the body to focus on the digestion process without the added stress of high temperatures and increased blood flow to the skin. However, it is important to listen to your body and adjust accordingly. If you feel light-headed or weak during a sauna session, it may be a sign that you need to eat something beforehand. Everyone’s body is different, so finding what works best for you is key.


In conclusion, while it is generally not recommended to eat immediately before a sauna session, individuals should wait a sufficient amount of time after eating to ensure proper digestion and comfort during the sauna. Paying attention to your body’s signals and adjusting accordingly is essential for a safe and enjoyable sauna experience. By consuming light, nourishing foods before and after a sauna session, you can maximize the benefits of this rejuvenating practice and support your overall well-being.


Should I do the sauna on an empty stomach?

Using a sauna on an empty stomach is considered safer than eating too close to a sauna session. However, it is recommended to eat something light two hours before your sauna session. More important than eating is drinking water, so make sure that you drink plenty of water before and after using the sauna.

Does the sauna help with digestion?

While the sauna helps you relax and detoxify, it can also assist with digestion. That’s why it’s recommended to use the sauna daily to discover the numerous benefits hidden within it.
