Infrared Saunas: Do They Heat Up Your Bedroom?

Infrared saunas are a modern twist on traditional saunas, offering a lower-temperature option. Instead of heating the air around you, infrared saunas use infrared lamps to warm your body directly. This means they can operate at a lower temperature, typically between 100°F and 150°F, while still providing therapeutic benefits.

One of the main benefits of an infrared sauna is that it can increase your core body temperature without causing extreme discomfort. This makes it a great option for people who find traditional saunas too hot or uncomfortable. The lower temperatures also allow you to tolerate longer sessions, which can provide greater therapeutic benefits.

Infrared saunas are said to offer a range of health benefits, including improved circulation, pain relief, and better heart health. They are also believed to be beneficial for detoxification, as sweating is one of the body's mechanisms for eliminating toxins.

However, it is important to note that infrared saunas can still cause overheating and dehydration, so caution should be exercised. It is recommended to stay hydrated before and after using an infrared sauna and to avoid using them if you are pregnant or have certain medical conditions.

Infrared saunas heat the body directly, not the air

Unlike traditional saunas, infrared saunas don't heat the air around you. Instead, they use infrared lamps and electromagnetic radiation to warm your body directly. This means that infrared saunas can operate at a lower temperature than traditional saunas while still providing therapeutic benefits. The lamps in infrared saunas focus a penetrating warmth directly on your skin to bring heat-therapy benefits.

Infrared saunas typically operate at temperatures between 110°F and 140°F (43.33°C and 60°C), while traditional saunas operate at temperatures between 150°F and 195°F (65.55°C and 90.55°C). This makes infrared saunas a more comfortable option for many people, especially those who find the high temperatures of traditional saunas too much to handle.

The infrared light used in these saunas penetrates the skin more deeply than the heat of a traditional sauna, leading to more sweating. This is because the infrared light heats the body from within, rather than heating the air around you. This deeper penetration of heat can also lead to a more abundant release of "toxins," although the scientific evidence for this claim is limited.

Infrared saunas offer many of the same benefits as traditional saunas, including relief from sore muscles, joint pain, improved circulation, and relief from chronic fatigue syndrome symptoms. They may also provide additional benefits such as improved heart health and reduced blood pressure. However, it's important to note that the research on the specific benefits of infrared saunas is still limited, and more studies are needed to fully understand their potential effects.

They operate at a lower temperature than traditional saunas

Unlike traditional saunas, which heat the air around you, infrared saunas use infrared lamps and electromagnetic radiation to warm your body directly. This means that they can operate at a lower temperature—usually between 110°F and 140°F (43.33°C and 60°C)—while still providing therapeutic benefits. Traditional saunas, on the other hand, typically operate between 150°F and 195°F (65.55°C and 90.55°C).

The lower temperature of infrared saunas is due to their use of infrared light, which is invisible to the human eye but experienced as heat. These infrared wavelengths penetrate the skin, heating the body directly without significantly heating the surrounding air. This direct heating of the body is claimed to be more efficient, with some manufacturers stating that 80% of the heat in an infrared sauna goes directly to warming the body, compared to only 20% in a traditional sauna.

The lower temperature of infrared saunas can make them more comfortable for users, especially those who find the high temperatures of traditional saunas too much to handle. This increased comfort may allow users to spend more time in the sauna and experience the benefits for longer. Additionally, the lower temperature may make infrared saunas a safer option, as there is a reduced risk of overheating and dehydration.

Despite the lower temperature, infrared saunas provide similar benefits to traditional saunas, including relief from sore muscles, joint pain, improved circulation, and relief from chronic fatigue syndrome symptoms. Some research also suggests that infrared saunas may provide additional benefits, such as improved heart health and reduced blood pressure. However, there is limited research directly comparing the two types of saunas, and the long-term effects of reduced heat in infrared saunas are not yet fully understood.

Infrared saunas can improve heart health

Infrared saunas can also improve vascular endothelial function and cardiac function. A study in the Journal of the American College of Cardiology found that repeated infrared sauna treatment improved vascular endothelial and cardiac function in patients with chronic heart failure. Additionally, saunas can help to reduce cardiac contractions associated with irregular heart rhythms.

The heat from infrared saunas can also have a positive impact on blood flow and heart rate. Within minutes of entering an infrared sauna, your blood vessels widen and increase blood flow, while your heart rate increases, mimicking the physiological effects of exercise. This can lead to improved circulation and a reduced risk of heart disease.

While the benefits of infrared saunas for heart health are promising, it is always recommended to consult with a healthcare professional before starting any new health routine, especially if you have pre-existing health conditions.

They can help with muscle recovery

Infrared saunas are a modern twist on traditional saunas, offering a lower-temperature option. Instead of heating the air around you, infrared saunas use infrared lamps to warm your body directly. This allows you to experience a more intense sweat at a lower temperature, and you can stay in the sauna longer.

Infrared saunas are particularly beneficial for muscle recovery, and here's why:

Improved Blood Circulation

The heat from infrared saunas increases blood circulation, which is crucial for muscle recovery. Improved blood flow delivers more oxygen and nutrients to the muscles, aiding in the repair of tissue damage and the rebuilding of muscles. This process also helps to reduce inflammation, providing relief from sore muscles and joint pain.

Enhanced Muscle Performance

Infrared sauna therapy has been shown to improve muscle performance during the recovery period after intense exercise. This is achieved by reducing inflammation and delaying onset muscle soreness (DOMS), which is caused by inflammation triggered by muscle damage.

Increased Muscle Growth and Density

Infrared heat therapy has been found to promote muscle growth and density, even in the absence of physical exercise. A study on mice showed that heat therapy increased muscle regrowth by 30% compared to a control group.

Reduced Recovery Time

Infrared light can penetrate muscles, increasing blood flow and helping the body recover faster. This means you can get back to your active lifestyle sooner without being slowed down by muscle soreness.

Improved Flexibility

Infrared saunas can increase your flexibility, which is essential for performance and injury prevention. Greater flexibility leads to improved joint mobility, reduced friction in the joints, and enhanced joint function, resulting in diminished stiffness and improved joint relaxation.

In summary, infrared saunas offer a range of benefits for muscle recovery, including improved circulation, enhanced muscle performance, increased muscle growth, reduced recovery time, and improved flexibility. These benefits can help athletes and active individuals maintain their performance and overall well-being.

Infrared saunas may improve sleep

Infrared sauna therapy can also enhance detoxification pathways, increase circulation, and improve mitochondria function, all of which benefit the entire body and, in turn, sleep. Additionally, a morning sauna session can energize the body for more activity, creating a better sleep drive. The passive cardio activity from a sauna session stimulates circulation similarly to exercise, providing an additional tool to help the body be active without the physical demands of exercise.

Using an infrared sauna before bed can also help prepare the body for sleep. Lowering the core body temperature is one of the signals that trigger the body's melatonin production at night. A hot bath or infrared sauna before bed can help lower the overall body temperature, aiding the body's natural preparation for sleep. Furthermore, bringing heat to the surface of the skin can help lower the body temperature as you cool down. It can also decrease cortisol levels caused by daily stress and induce relaxation, which further aids sleep.

Overall, while more research is needed, there is some evidence to suggest that infrared saunas may improve sleep quality and duration, contributing to overall well-being and health.
