Infrared Saunas: Exploring Their Health Benefits and Uses

Various studies show that passive heat therapies, such as saunas, can help with detoxification, pain relief, sleep, and cardiovascular health.

Let’s examine how regular sessions provide potential health benefits with less discomfort than traditional heated saunas.

Infrared saunas work differently from traditional saunas.

While traditional saunas heat the air around you, infrared saunas use light to generate body heat, showing evidence of various health benefits.

Infrared saunas operate at lower temperatures than traditional (“Finnish”) saunas, usually between 113-140°F (45-60°C).

This method of heating is more comfortable and tolerable than traditional saunas, which are characterized by high temperatures (ranging from 80-100°C), dry air, and relative humidity varying from 10-20%.

Infrared radiation can produce benefits from all spectrums of infrared energy, including low-level light therapy.

The three categories of therapeutic infrared light include

Full spectrum saunas that combine all three types of infrared energy provide complementary and additive effects on body tissues.

Traditional saunas rely on steam and hot air to create a high-temperature environment that can be too intense for some individuals.

Current evidence suggests infrared saunas can achieve results comparable to the benefits of traditional saunas, making them more accessible for those who find traditional saunas uncomfortable.

The unique method of heat generation used in infrared sauna therapy provides a more comfortable experience without the overwhelming heat of traditional saunas.

Infrared saunas differ from traditional saunas, which use flame-generated steam or heat.

Infrared light and electromagnetic energy generate heat that directly targets body tissues.

This makes the experience more comfortable when using a sauna to improve blood flow and metabolism.

Full-spectrum saunas that combine near, mid, and far-infrared wavelengths can provide total therapy with multiple health benefits.

From detoxification and pain relief to sleep and cardiovascular health, the potential benefits of infrared saunas supported by available studies include:

Infrared saunas can support detoxification and cleansing through sweating, an essential component of the detoxification system, as well as liver and kidney mechanisms.

Importantly, studies demonstrate that some toxins are preferentially eliminated through sweat.

The heat generated by far-infrared wavelengths penetrates deep into the body’s tissues, raises core body temperature, and induces sweating.

Deep sweating in sauna sessions removes toxins accumulated in the body, such as heavy metals like lead, cadmium, mercury, and arsenic.

Sauna sessions aid in the removal of toxic substances, which include

Lower temperatures make infrared saunas more comfortable and sustainable than traditional saunas.

The effectiveness of detoxification varies depending on individual factors such as overall health, hydration levels, and diet.

Current evidence shows that sauna therapy boosts immune cells in athletes.

Regular saunas boost immune system function by increasing white blood cell production in athletes.

The heat generated in sauna therapy stimulates cellular energy, enabling the body to fight infections and diseases.

This increase in white blood cells is essential for immune defense.

Also:

Sauna therapy is effective in pain management and relief for arthritis and fibromyalgia.

Infrared saunas generate heat from infrared light.

Heat penetrates deep into joints, muscles, and tissues, increasing circulation and speeding up oxygen flow to inflamed areas to promote natural pain relief.

Studies show that saunas can reduce pain in chronic pain patients by as much as 70% after just one session.

Saunas have been shown in multiple studies to provide relief to patients with chronic pain.

Deep heat therapy also promotes the release of beta-endorphins, which contribute to the feeling of well-being and pain relief.

Saunas can improve sleep quality by promoting relaxation and increasing melatonin production, the hormone that regulates sleep.

The session's gentle heat and calming effect reduce stress and prepare the body for a good night’s sleep.

Regular infrared sauna sessions have been linked to better sleep quality and are a consistent way to improve overall sleep health.

In addition to sleep, saunas also:

Infrared saunas and infrared sauna blankets can be helpful tools for athletes and active individuals who regularly exercise.

Saunas are a haven for stress relief and mental wellness.

The heat generated by saunas releases endorphins, the body’s natural “feel-good” chemicals, which create a calming and happy feeling.

Regular use of infrared saunas may reduce symptoms of depression and anxiety by promoting a calming effect and increasing stress tolerance.

The hermetic stress produced by heat exposure helps regulate stressors and makes it easier to cope with daily challenges.

Sauna use can also reduce brain fog and grogginess and lead to mental clarity and overall well-being.

Multiple studies of far-infrared sauna therapy have demonstrated evidence of cardiovascular benefits, including a boost in heart health maintenance.

The heat from the light increases body temperature, dilates blood vessels, and improves blood flow, which can lower blood pressure and improve cardiovascular function.

Regular sauna use can increase blood flow to twice the average rate, similar to moderate exercise.

This increased blood flow helps to:

Saunas are a natural way to support cardiovascular function.

Five 15-minute sauna sessions a week have been shown to improve cardiovascular function in individuals with heart conditions such as heart failure after 2-4 weeks.

Studies demonstrating the positive effect of regular infrared sauna use on heart health suggest significant potential as a complementary therapy for heart health.

Near-infrared light, closest to the visible spectrum, penetrates deep into the skin and aids collagen production and cell regeneration.

This can lead to better skin tone and younger-looking skin.

Infrared therapy can benefit the management of age-related inflammation and overall skin health. Current evidence shows the benefits of sauna therapy for the skin, including

Regularly using infrared saunas, which often use infrared lamps, shows potential for various health benefits.

Infrared saunas may help with weight loss by burning calories and increasing metabolism.

A 30-minute sauna session can burn 300-500 calories due to the increased heart rate, cardiac output, and metabolic rate caused by heat.

Regularly using saunas can raise your basal metabolic rate after the session, promoting fat-burning and weight loss.

Current studies suggest sauna is a helpful adjunctive therapy for those who want to boost their weight loss and overall body composition.

To maximize the benefits and avoid the risks, here are the guidelines:

1. For beginners, start at 110°F and limit sessions to 5-10 minutes.
2. You can increase the session time as you get used to the heat.
3. Maximum session time is 30 minutes.
4. Use an infrared sauna 3-4 times a week.

Bring water into the sauna and consider sports drinks with electrolytes.

If you feel dizzy or nauseous while in the sauna, exit immediately for your safety.

This will prevent further discomfort or complications.

After the session, rinse off in the shower to remove toxins from your skin and continue to hydrate to support the detox process.

Many health conditions have demonstrated potential for improvement with passive heat therapy, such as sauna, including hypertension, cardiovascular disease, thromboembolism, dementia, and respiratory conditions.

Passive heat therapy may improve musculoskeletal disorders, headaches, and flu severity while improving mental well-being, sleep, and longevity.

The current evidence suggests that an infrared sauna is a beneficial complementary therapy for heart health.

As mentioned earlier, long-term studies show that infrared sauna therapy can help reduce chronic pain, and skin conditions like acne, eczema, and psoriasis have improved with regular sauna sessions in several studies.

Although infrared saunas offer many benefits, not everyone should use this treatment modality.

People with certain medical conditions should avoid using saunas.

The following conditions are a contraindication to sauna therapy;

People with pacemakers should consult their doctors as magnets can interfere with the infrared heat generation device.

Women who are menstruating may experience heavier flow due to heat.

People on prescription drugs should always consult their healthcare provider, especially those taking medications that alter heat regulation and metabolism, including patients who take the following types of medications:

Alcohol intoxication can impair judgment and increase the risk of adverse reactions to heat, so it’s best to avoid sauna use when consuming alcohol.

Whether you want to improve your physical and mental well-being or find a new way to relax, an infrared sauna can be a great addition to your wellness journey.

Current studies suggest passive heat therapies such as infrared saunas can be a beneficial adjunct to improving overall wellness, supporting the immune system, relieving pain, promoting better sleep, and improving cardiovascular health.

Further research could be conclusive, but currently, despite positive results, there are limitations in study design and sample size.

However, evidence suggests many benefits may accrue with regular infrared sauna sessions.
