How Infrared Saunas Work

Infrared saunas use infrared light to heat the body, penetrating deeper into the skin than traditional saunas, which rely on hot air or steam. This deep penetration allows for more efficient detoxification and a host of other health benefits.

Benefits of Infrared Saunas


Infrared saunas help the body detoxify by increasing sweat production, which helps remove harmful substances such as heavy metals and environmental toxins.

Improved Circulation

The heat generated by infrared saunas causes the blood vessels to dilate, increasing circulation and oxygen delivery to the body’s tissues, including the brain.

Reduced Inflammation

Infrared saunas can help reduce inflammation by promoting relaxation and increasing blood flow, which helps carry away inflammatory substances.

Stress Relief and Relaxation

The soothing heat of an infrared sauna promotes relaxation and stress relief, which can have a positive effect on overall health, including brain health.

Enhanced Cognitive Function

Improved circulation from infrared sauna use can lead to increased oxygen and nutrient delivery to the brain, which may support enhanced cognitive function.


Infrared saunas may provide neuroprotection by reducing inflammation and oxidative stress in the brain, which can be damaging to brain cells.

Mood Enhancement

The relaxation and stress relief provided by infrared saunas may help improve mood by releasing endorphins and reducing cortisol levels, both of which are known to impact mental health.

Sleep Improvement

Infrared saunas can help promote better sleep by reducing stress and promoting relaxation, which in turn can lead to improved brain health.

Safety Considerations

It’s essential to consult with a healthcare professional before beginning any infrared sauna therapy, especially if you have pre-existing medical conditions or are pregnant or breastfeeding. Always follow the manufacturer’s guidelines and start with shorter sessions, gradually increasing the duration as your body adapts to the heat.

How to Use an Infrared Sauna


Before your infrared sauna session, make sure you are well-hydrated by drinking plenty of water. It’s also a good idea to wear lightweight, breathable clothing or a towel to ensure you’re comfortable during your session.

During the Session

Start with shorter sessions of about 15-20 minutes and gradually increase the duration as your body becomes more accustomed to the heat. Be sure to listen to your body and leave the sauna if you start feeling lightheaded, dizzy, or unwell.

After the Session

After your infrared sauna session, it’s essential to cool down gradually. Take a few minutes to sit or lie down and let your body adjust to the temperature change. Drink water to rehydrate, and consider taking a cool shower to help your body return to its normal temperature.


Infrared saunas offer a range of potential health benefits, including promoting brain health. The improved circulation, reduced inflammation, stress relief, and relaxation provided by infrared sauna use may contribute to enhanced cognitive function, neuroprotection, mood enhancement, and sleep improvement. As with any wellness practice, it’s essential to consult with a healthcare professional before starting infrared sauna therapy and follow the recommended guidelines to ensure a safe and enjoyable experience.
