Why sauna makes you happier and healthier? What scientists say?

Indeed, why sauna makes you happier and healthier? Let’s start with the “happier” part.

It is scientifically proven that visiting sauna on a regular basis increases the production of endorphins, serotonin, and dopamine – neurotransmitters that contribute to feelings of happiness and well-being. Concurrently, saunas help reduce cortisol levels, the primary stress hormone, which further supports relaxation and stress reduction. This combination of effects makes sauna bathing a beneficial practice for enhancing mood and alleviating stress.

Let’s See Why Sauna Makes You Happier

Why sauna makes you happier? Because it stimulates the happy hormones production. The effects of sauna sessions on the production of “happy hormones” and the reduction of the stress hormone cortisol are scientifically proven facts. Here’s an explanation of how these processes work:

Endorphins

Saunas stimulate the production of endorphins, which are natural painkillers and mood enhancers produced by the body. The heat exposure triggers the release of these neurochemicals, which can create feelings of euphoria and well-being. Studies have shown that endorphin levels increase after sauna sessions. This endorphin release is similar to the “runner’s high” experienced after prolonged exercise.

Serotonin

Saunas can also influence serotonin production, a neurotransmitter that regulates mood, appetite, and sleep. The relaxing environment and heat exposure can promote a sense of calm and well-being, which helps increase serotonin levels. Research has indicated that heat therapy, including sauna use, can enhance serotonin production, contributing to improved mood and reduced anxiety.

Dopamine

Dopamine is another neurotransmitter associated with pleasure and reward. The relaxing and pleasurable experience of a sauna session can stimulate dopamine production, enhancing feelings of happiness. Some studies have found that heat exposure from saunas can increase dopamine levels, contributing to an overall sense of well-being.

Sauna Reduces Cortisol Levels

Cortisol is the body’s primary stress hormone, released in response to stress and low blood-glucose concentration. Chronic high levels of cortisol are linked to various health issues, including anxiety, depression, and impaired cognitive function. Several studies have demonstrated that regular sauna use can lower cortisol levels. The heat exposure and the resultant relaxation response help reduce the production of cortisol. This decrease in cortisol levels can alleviate stress and promote relaxation.

Let’s See Why Sauna Makes You Healthier

Now, let’s go to the “healthier” part. The health benefits of saunas are supported by various scientific foundations, focusing on their effects on cardiovascular health, detoxification, relaxation, and more. Here are some key scientific foundations:

Cardiovascular Health – Heat Exposure and Heart Function

Saunas induce a cardiovascular response similar to moderate exercise. The heat causes blood vessels to dilate, increasing blood flow and heart rate. This can improve circulation and cardiovascular function. Regular sauna use has been associated with lower blood pressure and improved endothelial function, which is beneficial for heart health.

Detoxification – Sweating and Toxin Elimination

Sweating is a natural process through which the body eliminates toxins. Saunas promote intense sweating, which helps in the excretion of heavy metals, toxins, and other impurities from the body.

Relaxation and Stress Reduction – Endorphin Release and Muscle Relaxation: 

The heat from the sauna helps muscles to relax and reduces tension in the body. This can alleviate pain and discomfort from conditions like arthritis or muscle soreness. Saunas trigger the release of endorphins, which are natural feel-good hormones, promoting a sense of well-being and relaxation.

Skin Health – Improved Blood Flow and Pore Cleansing: 

Increased blood flow to the skin during sauna use can improve skin tone and elasticity. The sweating process also helps to cleanse pores, potentially reducing acne and improving overall skin appearance.

Immune System Support – Enhanced Immune Response:

 Regular sauna use has been linked to improved immune function. The heat can stimulate the production of white blood cells, which are crucial for fighting off infections and illnesses.

Respiratory Benefits – Improved Lung Function: 

Saunas can help open airways, loosen phlegm, and improve lung function. This can be particularly beneficial for individuals with respiratory conditions like asthma or bronchitis.

Mental Health – Reduction of Anxiety and Depression: 

The relaxing environment of a sauna can help reduce symptoms of anxiety and depression. The heat exposure also promotes better sleep, which is essential for mental health.

Weight Loss – Increased Caloric Burn: 

The increased heart rate and sweating in a sauna session can lead to a higher caloric burn, contributing to weight loss. It’s not a substitute for exercise but can complement a healthy lifestyle.

Pain Relief – Heat Therapy: 

Saunas provide a form of heat therapy that can relieve pain from chronic conditions like arthritis, fibromyalgia, and sore muscles. The heat helps to reduce inflammation and increase blood flow to painful areas. You have to thank endorphins for that, because they are natural painkillers and mood enhancers produced by the body.

Supporting Scientific Studies

Numerous studies support these benefits, just to mention a few:

  • Reduced Risk of Heart Deceases: A study published in the Journal of the American College of Cardiology found that regular sauna use was associated with a reduced risk of sudden cardiac death, coronary heart disease, and overall mortality.

  • Lowered blood pressure: Research in the Journal of Human Hypertension demonstrated that sauna bathing can lower blood pressure and improve arterial compliance.

  • Reduced Risk of Alzheimer’s and Dementia: A study in JAMA Internal Medicine found that frequent sauna use was associated with a reduced risk of Alzheimer’s and dementia.

  • Endorphins and Mood Enhancement: A study published in the journal Psychoneuroendocrinology found that sauna bathing can lead to significant increases in endorphin levels, contributing to improved mood and relaxation.

  • Serotonin and Well-being: Research published in the Journal of Affective Disorders highlighted that thermal therapy, including saunas, can positively affect serotonin levels, reducing symptoms of depression and anxiety.

  • Dopamine and Pleasure: A study in the journal Neuropsychopharmacology indicated that thermal stress, such as that experienced in saunas, can increase dopamine levels, enhancing pleasure and reward sensations.

  • Cortisol Reduction: Research in International Journal of Occupational Medicine and Environmental Health showed that regular sauna use can significantly lower cortisol levels, promoting relaxation and reducing stress.
