How a Sauna a Day Keeps the Stress Away

If you have been following me for a while, you will know how much I love my infrared sauna from Sunlighten! It is an integral part of my mental and physical health regimen, my favorite place to do brain research and detox my mind, and something I cannot live without! 

In this podcast (episode #423) and blog, I talk to the co-founder of Sunlighten Saunas Connie Zack. We discuss why infrared heat is so good for us, the difference between infrared and conventional saunas, the best way to use an infrared sauna, common mistakes we make when using infrared saunas, the science behind Sunlighten’s amazing saunas, and so much more! 

So what exactly is an infrared sauna? The light spectrum in an infrared sauna comes from the sun. It heats the body directly, whereas a conventional sauna only heats the air around the body.  

Although any kind of heat in a sauna can be good for us, infrared heat directly impacts our health, working naturally with our body to supercharge our cells without tiring us out or draining us. This allows for maximum detoxification and purification.

There are many benefits to an infrared sauna, including:

1. Detoxification: 

An infrared sauna can help detox the brain and body, right down to the level of our cells. This helps us get rid of impurities like heavy metals, which can impact our mental and physical health. In an infrared sauna, your body is sweating in a relaxed state, and can excrete more toxins and heal and repair itself. This is because infrared heat can reach the toxins that are surrounded by a protective layer of fat deep in the body, pulling out those substances you don’t normally get rid of by sweating in a conventional sauna or by going to the bathroom. 

Even if you avoid smoking, eat well, exercise regularly, practice mindfulness, use natural products and sleep well every night, you will be exposed to toxins that your body will store in a protective layer of fat. We all have bad stuff in our bodies, which is why it is essential that we take the time to detox our brains and bodies if we want to live a truly healthy lifestyle, and infrared saunas can help with this. 

2. Heart health and circulation:

As the heat in an infrared sauna heats your core up, your body has to work harder to cool you down, which improves your circulation and boosts your heart health. Better circulation, in turn, can clear your mind and help you process information faster, lower blood pressure, give your skin a gorgeous glow, help with pain relief, reduce inflammation, give you more energy, boost your metabolism, aid recovery and more. Instead of getting out of the sauna and feeling worn out, you will feel more energized, healthier and ready to take on any challenge!

3. Immunity: 

We should all be doing what we can to boost our immune systems, especially as the colder months approach, and an infrared sauna can help us do this. The energy from infrared saunas is absorbed on a cellular level, which positively affects the heat-shock proteins that strengthen the immune system. This not only boosts the immune system, but also helps free up the body to deal with any other health issues we may have. 

4. Pain relief, recovery and aging: 

Better blood circulation from infrared light means more toxins flow from the cellular level to the skin’s surface to improve cell health, aiding in muscle recovery and joint pain, which can be a big help after an intense workout, a physical accident or with conditions like arthritis or fibromyalgia. Near infrared waves in particular have a shorter frequency range and penetrate the epidermis layer of the skin, impacting the body at the cellular level, encouraging tissue growth and collagen production, helping with the negative effects of aging and speeding up muscle recovery.

5. Mental health:

Not only do saunas help us relax, which is certainly important for our mental health, but research on infrared saunas has also shown that it can have positive effects on our mood, helping with depression, anxiety and other types of mental distress. Just one infrared sauna treatment can potentially reduce depressive symptoms by up to 50%, with the benefits continuing for up to 6 weeks, while regular sessions in an infrared sauna can reduce cortisol levels, helping with toxic stress and burnout, and increase our clarity of mind and focus. 

I personally love using my Neurocycle app to detox my thoughts while I am detoxing my brain and body in my Sunlighten sauna—this is a perfect mental self-care cleanse, like a spa day for the mind!  

I also love to use my Sunlighten sauna to have “thinker moments”, where I just switch off and let my mind wander and daydream. These moments give the brain a rest and allow it to reboot and heal, which increases clarity of thought and organizes the networks of the brain, rather than just letting toxic mindsets build up in the brain and cause all sorts of mental health issues. (For more information on thinker moments and how to make them a part of your daily routine, see my books Cleaning Up Your Mental Mess and Think, Learn, Succeed). 

When it comes to using an infrared sauna, consistency and frequency are key. Even though it has all these great health benefits, it is important to remember that an infrared sauna is not a magic bullet or cure-all. It strengthens the brain and body over time, harnessing your natural power and helping you feel stronger and healthier than you did before.

When using an infrared sauna, you also need to listen to your body and focus on your unique needs. 

Many experts recommend up to forty minutes a day if you are an adult, depending on your health history and what program and type of sauna you are using. When you choose to use a sauna is up to you and what you are looking for. I personally avoid using my infrared sauna too late at night because it keeps me awake, unless I need to stay awake to work on a new book or research deadline!

It is, however, important to note that not all infrared saunas are created equal. There are three different parts of the infrared light spectrum, and each of which have different effects on the body and our health. Many infrared saunas don’t use all three types of infrared light, or don’t use them in an effective way or in the right frequency with the right materials and deliverability.  

This is why I love Sunlighten Saunas. They focus on the science behind their unique technology, always searching out the safest and most effective way to help provide optimum infrared light frequency and results, as well as creating non-toxic and sustainable products using high-quality materials that are safe and long-lasting. After using my infrared sauna regularly for several years, I can truly say I am impressed with the results. I am in my fifties and feel younger, healthier and happier than ever. It really is my “secret” weapon when it comes to my mental and physical health!

BiOptimizer’s Magnesium. If we want to be healthier mentally and physically, one of the best things we can possibly do is get several hours of quality sleep every night. The brain and body heal themselves when we sleep—it really is one of the most amazing processes, even if we are not conscious when it happens! Thankfully, there are ways we can improve our sleep quality and overall health, including taking MAGNESIUM. But most magnesium supplements use only the two cheapest synthetic forms—since they’re not full-spectrum, they won’t support better sleeping habits. There are actually 7 unique forms of magnesium, and you must get ALL of them if you want to experience its calming, sleep-enhancing effects. That’s why I recommend Magnesium Breakthrough by BiOptimizers. Simply take two capsules before you go to bed and you’ll be amazed by how much better you sleep, and how much more rested you feel when you wake up! And, this month, BiOptomizers are including free bottles of their full line of digestive health products on select orders, while supplies last. That means you are getting FREE products to try that will support your digestive system. Having an optimized digestive system means less energy trying to digest foods and absorbing more nutrients from the foods you eat. This special offer is ONLY available at with the code drleaf10 for 10% off any order.
