Exploring the Link between Sauna and Blood Sugar Levels: Can Saunas Raise Glucose?


Saunas have been used for centuries as a way to relax, detoxify the body, and promote overall health. However, recent studies have suggested that saunas may have an unexpected effect on blood sugar levels. Some research has indicated that saunas could potentially raise glucose levels, which would have serious implications for individuals with diabetes or other blood sugar regulation issues.


In order to understand how saunas might be linked to blood sugar levels, it is important to look at the physiological effects of sauna use. Saunas can cause the body to sweat heavily, which can lead to dehydration if the individual does not drink enough water. In addition to sweating, saunas also increase the heart rate and dilate blood vessels, which can have an impact on blood pressure.

The Connection to Blood Sugar

While dehydration and changes in blood pressure may be expected outcomes of sauna use, the potential impact on blood sugar levels is a newer concern. Some studies have indicated that saunas can cause an increase in glucose levels in the blood. This effect might be due to the stress that sauna use places on the body, which can lead to the release of cortisol and other hormones that can impact blood sugar regulation.


Overall, the connection between sauna use and blood sugar levels is an area that requires further research. While some studies have suggested that saunas could potentially raise glucose levels, other research has not found this effect. Individuals with diabetes or other blood sugar issues should be cautious when using saunas and monitor their glucose levels carefully. As more research is conducted in this area, we will gain a better understanding of how saunas impact blood sugar and overall health.

What is Sauna?

Sauna is a Finnish word that refers to a heated room or space where people go to sweat profusely. It is a traditional method of relaxation, medical treatment, and social activity in Nordic countries. Saunas can be found in homes, gyms, and spas worldwide.

Traditional saunas use hot rocks or stoves to heat the room to a temperature ranging from 70 to 100 degrees Celsius (158 to 212 degrees Fahrenheit). The heat causes the body to perspire, which in turn flushes out toxins and impurities through the skin. Sauna sessions can last anywhere from a few minutes to several hours, depending on the individual’s preference.

Modern saunas come in different types, including infrared saunas, steam saunas, and dry saunas. Infrared saunas use light to generate heat, while steam saunas use moist heat. Dry saunas, on the other hand, use low humidity to create a comfortable environment for sweating.

Aside from relaxation and detoxification, saunas have also been linked to various health benefits, such as improved cardiovascular health, reduced inflammation, and enhanced immune function. However, more research is needed to validate these claims.

How does Sauna Affect the Body?

A sauna is a small room or facility designed for dry or wet heat sessions that are believed to provide a range of health benefits, including the relief of stress, pain, and muscle tension. Sauna bathing has been a cultural practice for centuries and is widely popular among many cultures.

When you enter a sauna, the high temperature causes your body to start sweating, which helps to flush out toxins from your body. The heat and humidity can also increase blood flow, which can lower blood pressure and improve circulation in the body. This increased blood flow can help to relieve muscle pain and tension, boost the immune system, and promote overall relaxation and mental wellbeing.

Furthermore, the heat exposure can cause your body to release endorphins, which are the body’s natural painkillers. These endorphins can help to reduce feelings of stress, anxiety, and depression and promote overall feelings of calmness and relaxation.

While sauna use can be beneficial, it is important to note that it may not be suitable for everyone, especially those with preexisting medical conditions or pregnant women. It is important to consult with a healthcare provider before undergoing sauna therapy to ensure it is safe for you.

Can Saunas Raise Glucose?

Saunas have been a popular form of relaxation and therapy for centuries. In recent years, saunas have been studied for their potential health benefits, including their effects on blood sugar levels. Some studies suggest that saunas may raise glucose levels, while others claim the opposite. So, can saunas raise glucose?

One study found that men who used a sauna had higher glucose levels after the sauna session than before. This led the researchers to conclude that saunas may have a negative impact on glucose control. However, another study found that women who used a sauna had lower glucose levels after the session. The reasons for these conflicting findings are not yet clear.

It is important to note that the effects of saunas on glucose levels may depend on individual factors, such as age, health status, and glucose tolerance. Additionally, the temperature and duration of sauna use may also impact its effects on glucose levels.

So, the question of whether saunas can raise glucose remains unanswered. More research is needed to fully understand the relationship between saunas and blood sugar levels. Until then, individuals with diabetes or those at risk for diabetes should speak with their healthcare provider before using a sauna.

Overall, the evidence regarding the link between saunas and blood sugar levels is inconclusive. While some studies show that regular sauna use can decrease blood sugar levels, others suggest that it may have little to no effect, or even raise glucose levels in some individuals.

However, it is clear that saunas have numerous health benefits beyond their potential impact on blood sugar. They are known to reduce stress, improve cardiovascular health, and promote relaxation and feelings of well-being.

As with any health intervention, it is important to consult with a healthcare professional before incorporating saunas into a diabetes management plan. Individuals with diabetes should monitor their blood sugar levels carefully when using a sauna and follow all safety precautions to prevent dehydration or other adverse reactions.
