Studies have shown that sauna use can improve cardiovascular function, and as a result lower the risk of heart disease.

A study has shown that people using a sauna 4 times per week compared to only 1 time per week may decrease the risk of cardiac death by 63%. They also may see a decrease risk of death from cardiovascular disease by 50%, and a 40% decreased risk in all-cause mortality.

Sauna use helps to lower inflammation from working out and thereby eliminating muscle soreness.

Improved circulation delivers oxygen-rich blood to sore muscles, speeding up recovery.

The heat relaxes muscles, reduces stiffness, and can help alleviate joint pain, arthritis, or post-workout soreness.

Saunas have been found to help alleviate symptoms of chronic conditions such as rheumatoid arthritis, fibromyalgia, and other chronic conditions.

The relaxation and therapeutic benefits of sauna use can contribute to pain relief and reduce discomfort.

The relaxation and endorphin release associated with sauna use as well as lowering cortisol levels, the hormone responsible for feelings of stress and anxiety, can reduce stress.

The heat from a sauna causes us to sweat, and this process helps the body eliminate waste, essentially expelling toxins through perspiration. As Gary Brecka explains, “The body has two types of sweating. Passive sweating, which eliminates waste without the goal of lowering body temperature, and active sweating, which helps cool the body down.”

But what exactly are these toxins? A 2012 study found that using a sauna led participants to sweat out heavy metals like arsenic, cadmium, lead, and mercury, which can enter the body through food, skin contact, or inhalation. Saunas also aid in removing other toxins such as harmful chemicals, pesticides, mycotoxins, and BPA, as well as toxins from drugs and alcohol.

Saunas have been shown to be extremely beneficial to the health of the skin. Sauna use results in sweating, which in turn results in unclogging of pores and removing toxins and impurities from your body.

Combining this with increase blood circulation can lead to improved skin health.

Regularly using a sauna has been shown to improve the quality of sleep.

The heat from the sauna can help to relieve stress, increase relaxation, and recover from aches and pains leading to a better nights sleep.

Using a sauna regularly has been shown to release endorphins, the feel good hormone, lower cortisol, and provide an environment of relaxation leading to an improved mood.

Post-workout sauna use has been known to increase blood flow to the muscles, leading to muscle repair.

Heat from the sauna also relaxes muscles, reduces stiffness, and can help alleviate muscle soreness.

The increase in circulation from using the sauna can help deliver oxygen-rich blood to sore muscles, speeding up recovery.

Saunas have been scientifically proven to boost and strengthen your immune system.

A study that was done in 2013 showed an increase in the white blood cell count, which helps your body to fight off infections and diseases.

Gary Brecka says, "The passive sweating process is one of the most efficient ways to get bacteria, viruses and all sorts of other things that we’re trying to detoxify from our body, out of our body."

A study of sauna use has been proven to lower inflammation which can lead to a decreased risk of acute and chronic disease conditions.

Saunas have been shown to increase circulation with oxygen-rich blood flow helping to reduce inflammation and swelling to alleviate chronic pain.

Studieshave shown that using the sauna for just 30 minutes 3 times a week, for just 12 weeks has shown to reduce insulin and blood sugar levels by 31%.

Sauna use is actually well-known for its benefits on respiratory infections.

One study showed that sauna use among 2,000 men had reduced respiratory diseases by 27% and 41%, in those who used the sauna 2-3 times per week and more than 4 times per week, respectively. This was compared to those who used a sauna less than 1 time per week.

A study showed that a moderate to high frequency of sauna bathing was associated with lowered risks of dementia and Alzheimer's disease.

Further studies are warranted to establish the potential mechanisms linking sauna bathing and memory diseases.

It's been shown that using a sauna post-workout can in crease the blood flow to the muscles, leading to muscle repair and increasing other pro-growth factors.

A study has shown that just 2 - 20 minute sauna sessions at 176 degrees separated by a 30-minute cooling period can increase growth hormone two-fold.

Saunas show that heat stress can release growth hormone, which discourages protein breakdown and supports muscle recovery.
