Saunas have long been regarded as a way to relax and unwind. They are believed to offer a variety of health benefits, such as reducing stress, improving circulation, and aiding in the body’s detoxification process.

Many people incorporate sauna bathing into their healthy lifestyle, whether after exercise or simply to relieve fatigue. However, while saunas have numerous benefits, they also come with certain health risks that are important to understand and address.

Health Risks of Sauna Bathing

Despite the soothing warmth of a sauna, it may not be safe for everyone. If used excessively or incorrectly, saunas can lead to significant health risks.

Here are some potential risks associated with sauna use:

Dehydration

One of the immediate effects of sauna bathing is the loss of body fluids and electrolytes. Without adequate hydration, this can lead to dehydration.

Symptoms of dehydration include dizziness, fatigue, and dry mouth. In severe cases, dehydration can impair kidney function, lower blood pressure, and even cause fainting.

Risk of Blood Pressure Fluctuations

Sauna use can impact the cardiovascular system, particularly blood pressure. The extreme temperature shifts can raise blood pressure, while the dilation of blood vessels can cause a drop in blood pressure.

For individuals with low blood pressure or those recovering from a heart attack, it is strongly recommended to consult a doctor before using a sauna.

Fertility Issues

Studies have shown that excessive sauna use can significantly reduce sperm production. This occurs because of the heat around the scrotum, which interferes with the sperm formation process.

The good news is that this reduction in fertility may be temporary and can improve after stopping sauna use. However, further research is needed to fully understand how sauna use affects male fertility in the long term.

Risk of Birth Defects

Exposure to high temperatures during pregnancy has been linked to an increased risk of birth defects. This happens when a pregnant woman’s body temperature rises too high, particularly in the early stages of pregnancy, due to hot water immersion, sauna use, fever, or exposure to extreme temperatures.

Although recent studies suggest not all heat exposure carries the same risks, it is still advisable for pregnant women to consult their doctor before using a sauna.

Who Should Not Use a Sauna?

While saunas offer many benefits, certain groups are more vulnerable to the associated risks. Here are some people who should avoid using a sauna:

Seniors Aged 65 and Over

Older adults should exercise caution when using a sauna because their bodies are less efficient at regulating temperature compared to when they were younger.

Children Under the Age of Seven

Young children, especially those under seven, have an immature system for regulating body temperature. This makes them more susceptible to overheating and dehydration in environments like a sauna.

Pregnant Women

In addition to the risks of dehydration and dizziness, pregnant women should seek advice from their doctor before using a sauna. High heat can elevate core body temperature, which could potentially pose risks to the pregnancy.

People with a History of Seizures

Those with a history of seizure disorders, such as epilepsy, should avoid sauna use. Extreme temperature fluctuations can trigger seizures, particularly in individuals who are sensitive to these changes.

Understanding the potential risks and recognizing the limitations of sauna use is essential for maintaining health and safety. If you belong to a vulnerable group, it’s important to consult a doctor before using a sauna to ensure you can enjoy its benefits without putting your health at risk.
