In today's blog post, we'll be delving into an intriguing topic - the potential role of saunas, particularly infrared saunas, in supporting liver detoxification and health optimisation. The internet is brimming with tales touting the sauna as a direct means of "cleansing the liver" and promoting the idea that the "liver filters the blood". However, these assertions are not entirely accurate. Despite this, there are indeed ways in which saunas can bolster liver detoxification, as supported by scientific literature. We'll explore these mechanisms further on, but first, let's ensure we're on the same wavelength about detoxification as a whole.
Sauna Liver Detoxification 101: Back to Basics
Contrary to popular belief, the liver does not function as a filter. Rather, it processes toxins to facilitate their elimination from the body, generally without storing them. The process through which the liver achieves this is incredibly intricate. In essence, though somewhat simplified, the liver breaks down toxins and makes them more manageable for elimination during several phases. Ideally, these toxins are then expelled from your body via your stools and urine. Let's break this down even further.
Phase 1: The toxin molecule is oxidised, preparing it for the next phase.
Phase 2: The molecule is conjugated to one of several chemical groups. This has two main functions: firstly, to lessen the metabolic activity of the toxin, and secondly, to increase its water solubility.
Phase 3: The conjugate is exported into the bile and transported into the intestines. Here, it can either be excreted in the faeces or reabsorbed into the bloodstream to be expelled from the body via urine.
So while the liver doesn't filter toxins in the traditional sense, its function is vital in ensuring these toxins are effectively processed and removed from our bodies. Sometimes, however, our liver doesn't work the way it is supposed to. Let's find out why:
Maintaining Healthy Liver Function
Under certain circumstances, these phases may not operate at their best. Factors such as age, high toxin intake, nutritional deficiencies, and even your circadian rhythm – the internal 24-hour clock governing your bodily functions – can all impact the efficiency of your liver's detoxification process.
That's because, at certain times of the day, these processes are increased while others are decreased. In saying that, the liver does not always completely remove all toxins due to these factors, which leads us to the next topic; how you can support your liver.
Enhancing Detoxification with Dietary Fibre
To boost this process, dietary fibre is your friend. Foods such as kidney beans, legumes, fruits, vegetables, and tubers are rich in fibre and can help facilitate toxin elimination. If you're following a specific diet that excludes beans and legumes, don't worry. You can still achieve a good daily fibre intake with vegetables and tubers. But what happens if your detox pathways aren't enough?
Avoiding Toxin Recirculation
If detoxification isn't working efficiently, toxins can end up being re-released into the bloodstream and have to go through the liver's processing phases again, a phenomenon known as "recirculation".
While traditional saunas and infrared saunas both cause heat stress and thermoregulation for releasing toxins, infrared therapy, specifically far infrared saunas, penetrates deep into fat cells to release toxins previously stored away, which enhances the detoxification of these harmful substances.
Moreover, the infrared sauna experience may be more tolerable for some people, particularly those with certain medical conditions due to the lower air temperatures.
Let's explore this deeper.
Can Sitting in a Sauna Benefit Your Liver?
Yes, sitting in a sauna can benefit your liver by enabling it to focus on its core functions while other toxin-elimination methods are utilised.
As we mentioned earlier, when the body is overloaded with toxins it struggles to process them, and the liver attempts to detoxify these compounds; however, it does not completely eliminate them all.
Here's where saunas support liver detoxification:
By using a sauna regularly and encouraging toxins to leave your body through sweating, you're allowing your liver to focus its energy on dealing with toxins that are best processed and eliminated through it and the kidneys, stool, and urine.
The answer is a resounding yes, and here is why. The skin plays a central role in the body's detoxification system and sweating is its natural process that helps eliminate various toxins from the body. This method of toxin removal can release different heavy metals and toxins more efficiently than solely the liver, kidneys, intestines, and urinary system.
So to recap, sauna therapy removes toxic substances from the human body through the body's ability to sweat profusely, utilising one additional detoxification process, out of the four. When the body uses all four of these pathways it has a better opportunity to process these toxins than it would otherwise using only three, two or one.
Speaking of which, let's explore other impacts an infrared sauna session might have on the other organs in the body.
Is Infrared Sauna Good For Your Organs?
Infrared sauna sessions seem to be beneficial for your vital organs according to clinical studies. Let's look closer at the physiological effects of infrared saunas on our eight vital organs - the brain, heart, lungs, kidneys, liver, gallbladder, pancreas, and stomach.
Brain: Infrared saunas stimulate circulation throughout the body, including an improved blood flow to the brain which has been shown to improve cognitive function.
Heart: Similarly, the dilation of blood vessels and an increased heart rate not only provides a moderate exercise for your cardiovascular system, but it also increases circulation benefiting symptoms and risks of cardiovascular disease.
Kidneys: The kidneys, tasked with filtering our blood, may also benefit from the increased blood flow, facilitating more efficient waste removal.
Liver: As talked about throughout this blog, the liver is crucial for detoxification, and can use this enhanced circulation to function more effectively, potentially aiding in toxin removal.
Gallbladder and Pancreas: Similarly, the gallbladder and pancreas, which aid in digestion and regulation of blood sugar, respectively, can also benefit from improved circulation.
Stomach: Finally, the stomach, our primary organ for digestion, could also see sauna benefits. While not directly affected by the heat, the overall relaxation and stress relief provided by a sauna session could potentially lead to better digestive health.
In a nutshell, infrared sauna sessions could be your secret weapon to enhanced overall well-being. From boosting brain function to supporting heart health and aiding digestion, the benefits are multifaceted. Remember, every step of your wellness journey is important, and taking care of your vital organs is a significant part of that journey. Let's digest this information in a quick summary:
Digesting the Truth About Infrared Sauna Therapy and Liver Detoxification
In retrospect, the answers to questions like 'Can sitting in a sauna benefit your liver?' and 'Does sauna use have any impact on the liver at all?' are more nuanced than one might initially think.
To distil it down, the more toxins you can eliminate through your skin via sweating, the less strain is placed on your internal organs. This, in turn, provides your liver with a bit of respite, reducing its workload and preventing toxins from re-circulating in the body.
So, while the notion that an infrared sauna directly detoxifies the liver might not hold entirely true, it does play a supportive role in your body's overall detoxification processes. By aiding in the elimination of toxins, it indirectly contributes to the well-being of your liver.
As you enjoy your sauna sessions, remember that while they may not directly detox your liver, they're still playing a vital part in promoting your body's natural detoxification processes. So go ahead, relax in the warmth of your infrared sauna, and let it support your journey towards improved health and well-being!
