Vitamin D is a vital nutrient that the body needs to function properly.
It helps with the absorption of calcium, supports immune system health, and is essential for healthy bones and teeth.
There are a variety of ways to get vitamin D, including exposure to sunlight, consuming foods rich in the nutrient, and taking supplements.
In recent years, infrared saunas have gained popularity as a potential source of vitamin D.
But can you really get vitamin D from an infrared sauna?
In this article, we'll explore the relationship between infrared saunas and vitamin D and separate fact from fiction.

1. What is an Infrared Sauna?
An infrared sauna is a type of sauna that uses infrared heaters to emit infrared light.
This light is absorbed by the skin, causing the body to sweat and release toxins. Infrared saunas are typically smaller than traditional saunas and operate at a lower temperature.
They are often used for relaxation, detoxification, and to relieve muscle pain.
2. What is Vitamin D?
Vitamin D is a fat-soluble vitamin that is essential for bone health, immune system function, and overall well-being.
It is produced in the body when the skin is exposed to sunlight and can also be found in certain foods, such as fatty fish, egg yolks, and fortified dairy products.
Vitamin D plays a crucial role in calcium absorption, which is essential for strong bones and teeth.
3. Can You Get Vitamin D from an Infrared Sauna?
While some proponents of infrared saunas claim that they can provide vitamin D, the reality is that they do not.
Infrared saunas emit light in the infrared spectrum, which is not the same as the UVB light that the body needs to produce vitamin D.
Therefore, it is not possible to get vitamin D from an infrared sauna.
4. The Science Behind Vitamin D Production
Vitamin D is produced in the body when the skin is exposed to UVB light.
UVB light has a wavelength of 290-320 nm and is responsible for stimulating vitamin D production in the skin.
When UVB light hits the skin, it converts a type of cholesterol called 7-dehydrocholesterol (7-DHC) into vitamin D3.
Vitamin D3 then travels to the liver and kidneys, where it is converted into the active form of vitamin D that the body can use.
5. How Much Vitamin D Can You Get from an Infrared Sauna?
As we've established, it is not possible to get vitamin D from an infrared sauna.
While the light emitted by the sauna may have some health benefits, it does not provide the UVB light needed for vitamin D production.
6. Other Benefits of Infrared Saunas
While infrared saunas do not provide vitamin D, they do offer a range of other potential health benefits.
Research suggests that regular use of an infrared sauna may help to reduce inflammation, improve circulation, and promote relaxation.
Additionally, some studies have suggested that infrared saunas may help to relieve symptoms of conditions such as arthritis and fibromyalgia.
7. Best Ways to Get Enough Vitamin D
While an infrared sauna cannot provide vitamin D, there are several other ways to ensure that you get enough of this important nutrient.
The most natural way to get vitamin D is by spending time in the sun.
The body can produce vitamin D when the skin is exposed to UVB light, although it is important to be careful not to get sunburned.
It is recommended that individuals get at least 10-15 minutes of sun exposure several times a week, without sunscreen, to ensure sufficient vitamin D levels.
If you live in an area with limited sunlight, or during the winter months when the sun's rays are weaker, getting enough vitamin D from sunlight alone may be challenging.
In these cases, it is important to consume foods that are high in vitamin D, such as fatty fish, egg yolks, and fortified dairy products.
Supplements are also available for those who need an additional source of vitamin D.
8. Who Should Avoid Infrared Saunas?
While infrared saunas are generally considered safe for most people, there are certain groups of individuals who should avoid using them.
Pregnant women, children, and individuals with certain medical conditions such as heart disease or low blood pressure should consult with a doctor before using an infrared sauna.
It is also important to stay well hydrated when using a sauna to avoid dehydration.
9. Precautions for Using an Infrared Sauna
To ensure the safety and effectiveness of an infrared sauna, there are several precautions that should be taken.
First, it is important to stay well hydrated before, during, and after using the sauna.
It is also recommended that individuals limit their time in the sauna to 20-30 minutes at a time and avoid using the sauna if they are feeling ill or have a fever.
It is also important to follow the manufacturer's instructions for using the sauna and to ensure that the sauna is properly ventilated to avoid carbon monoxide poisoning.
Finally, it is recommended that individuals who are new to using an infrared sauna start with shorter sessions and gradually build up their time in the sauna to avoid any potential side effects.
While infrared saunas may offer a range of potential health benefits, they cannot provide vitamin D.
To ensure that you get enough vitamin D, it is important to spend time in the sun, consume vitamin D-rich foods, or take supplements as needed.
If you choose to use an infrared sauna, it is important to take precautions to ensure safety and effectiveness.
- Can infrared saunas cause skin damage?
- While infrared saunas are generally considered safe, prolonged exposure to heat can cause skin irritation or dryness. It is important to stay well hydrated and to limit your time in the sauna to avoid any potential skin damage.
- Are there any medical conditions that could be worsened by using an infrared sauna?
- Individuals with certain medical conditions such as heart disease or low blood pressure should consult with a doctor before using an infrared sauna. Pregnant women and children should also avoid using a sauna without medical supervision.
