Infrared saunas are a simple yet effective way to support your immune system. They work by boosting the production of white blood cells and heat shock proteins, both crucial in helping your body fight off illness.

While saunas won’t cure a cold, using them regularly can help prevent sickness before it starts. Curious how to make the most of these benefits?

Keep reading for tips on using saunas safely and effectively, especially during cold season.

Are infrared saunas good for the immune system?

Yes, infrared saunas are great for boosting the immune system. When your body is exposed to the heat from an infrared sauna, it mimics the natural fever response. This stimulates your body to produce more white blood cells, which are essential for fighting off infections.

Over time, regular use can strengthen your immune system, helping you fend off viruses and bacteria more effectively. The rise in body temperature also promotes better circulation, which can help deliver oxygen and nutrients to cells faster. This boosts the body's overall ability to heal itself and defend against sickness.

Plus, the relaxation and stress relief you get from regular sessions have their own immune-boosting benefits since chronic stress can wear down your defenses over time.

How long should you stay in an infrared sauna to boost your immune system?

For best results, aim for 20 to 30 minutes in the sauna. Start on the lower end if you're new, and work your way up as your body gets used to the heat. The idea is to raise your core temperature enough to trigger an immune response without overdoing it.

You’ll want to hydrate before and after your session to avoid dehydration, especially if you’re sweating a lot.

How do infrared saunas boost the immune system?

Infrared saunas boost the immune system by stimulating the production of heat shock proteins and increasing white blood cell count. Heat shock proteins protect and repair cells, helping them withstand stress and recover more efficiently.

At the same time, the rise in core body temperature mimics a fever, encouraging your body to create more white blood cells, which are essential in defending against infections.

These two processes combined help improve your body’s ability to fight off illness and promote overall immune health.

Do infrared saunas increase heat shock proteins?

Yes, infrared saunas do increase heat shock proteins (HSPs). These proteins act like cellular protectors, helping your body manage stress at a microscopic level. When you expose your body to the controlled heat of an infrared sauna, it responds by producing more HSPs. These proteins help repair damaged cells, support immune function, and even aid in the recovery of muscles.

HSPs play a crucial role in the body’s response to environmental stressors. When your cells are stressed by things like high heat, they can start to misfold and malfunction. Heat shock proteins swoop in to prevent this from happening, ensuring your cells stay healthy and functioning properly. This is especially helpful in boosting immunity, as strong cells are better able to fend off potential invaders like viruses and bacteria.

In addition to cellular protection, the production of HSPs also supports longevity and resilience. Regular exposure to sauna heat can train your body to produce more HSPs, meaning you're better prepared to handle stressors outside of the sauna environment. So, while you might think you’re just sweating it out, your body is actually working behind the scenes to fortify itself.

Should I sauna if I have a cold or flu?

No, it's best to avoid using a sauna when you have a cold or flu, especially if you're experiencing fever, weakness, or severe symptoms. The heat can put extra strain on your body, which is already working hard to fight the illness.

On top of that, saunas cause significant sweating, leading to dehydration, which can make recovery more difficult. Rest and hydration are key during illness, and it's better to wait until you're feeling better before resuming sauna sessions.

Can infrared saunas give you a cold or flu?

No, infrared saunas can't give you a cold or flu. The heat they generate can actually help to support your immune system rather than make you sick. What’s important to remember, though, is that infrared saunas are communal in some settings, like gyms or spas. If the sauna itself isn’t cleaned properly, or if someone uses it while they're sick, you could potentially be exposed to germs. But the sauna heat itself isn’t a cause of illness.

In fact, infrared saunas can act as a preventative measure for many people. By boosting circulation, encouraging detoxification, and strengthening your immune response, they can help you stay healthy during flu season or when you're feeling run down. It’s all about building resilience through regular use.

Can infrared saunas treat a cold or flu?

While infrared saunas won't cure a cold or flu, they can help alleviate some symptoms and make you feel a little more comfortable. The warmth from the sauna can loosen up congestion in your nasal passages, making it easier to breathe. If you're dealing with muscle aches, the heat can help relax tight muscles and soothe body pain, giving you some relief from the discomfort that often comes with being sick.

That said, a sauna should never be your only line of defense. Rest, hydration, and sometimes medication are still necessary to recover fully from a cold or flu. The sauna can be a part of your self-care, but it’s not a cure. It’s more about managing symptoms and supporting your body through the illness, helping you recover a little more comfortably.

Infrared Saunas Don't Cure But Prevent Colds

While infrared saunas aren’t a cure for colds, they can help prevent them by boosting your immune system. They increase heat shock proteins and white blood cells, both of which strengthen your body’s defenses.

For best results, use the sauna regularly to maintain these benefits. Stay hydrated before and after each session to avoid dehydration, and limit your time to about 20-30 minutes to prevent overexertion.

Pairing saunas with good sleep, a balanced diet, and regular exercise further supports your immune health.
