The Comfort of Immersing in a Sauna: Reasons It Helps Improve Depression

Mental Benefits of Sauna

In modern society, stress and anxiety have become unavoidable. Amidst this, saunas are gaining attention as a method to refresh the mind and body. As many studies indicate, saunas are not just a means of relaxation but are also reported to be effective in improving depression and anxiety disorders. Particularly, research conducted in Japan suggests that sauna bathing can reduce depression and stress, enhancing the quality of life. Given this background, saunas can become an important part of daily life.

Furthermore, taking time to focus on your own breathing and heartbeat creates a state of mindfulness, enhancing mental stability. This allows you to free yourself from unpleasant thoughts and memories, helping you regain energy for the day. Regular sauna use is not only pleasurable but also greatly beneficial for health. Therefore, this habit, recommended by many experts, is gaining attention as a component supporting a healthy lifestyle for both mind and body.

Impact of Sauna on Mental Health

Sauna bathing is believed to have effects on depression and anxiety disorders. According to research conducted in Japan in 2021, saunas may reduce depressive symptoms and improve the quality of life. This is because saunas provide a space to relax away from daily life, offering time to forget unpleasant thoughts and memories. Such time helps lighten the mind and alleviate daily stress.

Regulating Brain Hormone Balance

During sauna bathing, the rise in body temperature leads to the release of endorphins and other brain hormones. This elevates mood and decreases the level of cortisol, a stress hormone. As a result, mental tension is relieved, and feelings of anxiety and depression are alleviated. This process is also known as natural healing power, providing relaxation effects to many people.

Effects on the Autonomic Nervous System

Saunas are said to positively affect the autonomic nervous system. In a warm environment, the balance between the sympathetic and parasympathetic nervous systems is adjusted, activating the entire autonomic nervous system. This activation improves blood circulation and promotes metabolism. Additionally, this process efficiently supplies oxygen and nutrients throughout the body, aiding in fatigue recovery.

Mindfulness and Stress Relief

In the quiet sauna room, you can have time to face yourself. By focusing on your breathing and heartbeat during this time, you may enter a state of mindfulness. This state not only relaxes the mind and body but also temporarily frees you from the stress felt in daily life.

Precautions: Preventing Dehydration

Due to excessive sweating, hydration is essential. Be sure to hydrate properly with water or sports drinks, rather than alcoholic beverages. Additionally, it is important to use the sauna without overexerting yourself and while consulting your own physical condition.

Recommended Frequency: 4 Times a Week or More

A study published in 2018 shows that people who take sauna baths about 4 to 7 times a week have a 78% lower risk of developing depression compared to those who do it less frequently. This suggests that regular use may also be effective from a preventive perspective.

What is the “Aligning” Process?

After a sauna, there is a process called “aligning” where you adjust your body temperature with a cold shower or bath. This process, while avoiding sudden blood pressure changes, can also be expected to provide further relaxation effects.

Adapting to Modern Society

In today’s busy society, there are various mental health challenges such as insomnia, chronic fatigue, and autonomic nervous system disorders. However, with a certain frequency and appropriate methods—especially in combination with professional medical care—saunas are gaining attention as a means to approach these issues. However, it is not a complete cure, so it is often necessary to consider combining it with visits to professional medical institutions.

Is it true that saunas are effective for depression symptoms?

Yes, using a sauna is believed to have effects in reducing depression symptoms. According to research, entering a sauna raises body temperature, activating the body’s cooling system. This promotes the secretion of endorphins and serotonin, supporting mental health. Additionally, training the autonomic nervous system helps relieve stress.

How often should I use a sauna?

It depends on individual health conditions and lifestyle, but in many cases, 1 to 3 times a week is recommended. Using it too frequently can have the opposite effect, so it’s important to incorporate it at a moderate pace.

Is the sauna effective for hyperhidrosis?

Yes, it is. For those with hyperhidrosis, the idea of “sweating even more” might be concerning, but a sauna habit can surprisingly lead to improvement. Regular use can normalize sweat gland function, serving as a measure against hyperhidrosis.

Tell me about the effects on the autonomic nervous system.

Entering a hot sauna stimulates the sympathetic nervous system, while a cold bath stimulates the parasympathetic nervous system. This alternating action balances the autonomic nervous system. As a result, it improves stress tolerance and can also help with insomnia and mood disorders.

What are the effects of saunas from the perspective of certified professionals?

Official髭男dism member Daisuke Ozasa, as a Sauna & Spa Professional, highly evaluates its effects. As mentioned in tweets, its effectiveness against “depression” is also gaining attention. Supported by scientific evidence, it is endorsed by many people.
