No, you cannot "sweat out" a virus. Viruses are neutralized by your immune system, not expelled through pores or sweat glands. While a sauna session can offer temporary symptom relief—like clearing congestion or easing muscle aches—it will not shorten the duration of the illness.
The fever response can cause sweating, which may be why some people believe sweating can cure a cold. Sweat's main job is to cool you down and regulate your body temperature. While sweat contains electrolytes and tiny amounts of toxins, viruses aren't trapped in sweat glands, so they can't be released through sweat.
Visiting a sauna can help temporarily relieve mild cold symptoms—like sinus congestion and muscle aches—by loosening mucus and increasing circulation. However, it does not cure viruses. You should avoid saunas completely if you have a fever, chills, or flu-like symptoms, as the intense heat will overtax your body.
The "rule of 200" is a guideline for maintaining safety and comfort by balancing temperature and humidity. According to the rule of 200, the sum of your sauna temperature and humidity readings shouldn't exceed 200. For example, if your sauna is set to 170°F (76.6°C), the humidity level should be around 30%.
The answer is yes: a sauna does help when you have a cold. It can give relief to symptoms and a boost to the immune system, due to the body's reactions to high temperatures. A sauna increases your body temperature, inducing sweating. This can help get rid of toxins through the skin and clear your airways.
No, you cannot "sweat out" a cold. Sweating does not eliminate the virus. In fact, intentionally overheating yourself can cause dehydration, disrupt the rest your immune system needs, and actually make you feel worse.
A 2019 research review found that sweat contains some toxins. However, this same review noted that sweating in a sauna is not an effective way to “detoxify.” However, in some cultures, sweating has long been recommended as a detoxification remedy.
30 minutes in a sauna is physiologically comparable to light cardio, such as a brisk walk, light cycling, or moderate calisthenics.
Joe Rogan typically keeps his traditional dry sauna at an intense temperature ranging between 180∘F180 raised to the composed with power F𝟏𝟖𝟎∘𝐅 and 200∘F200 raised to the composed with power F𝟐𝟎𝟎∘𝐅 (82∘C82 raised to the composed with power C82∘C – 93∘C93 raised to the composed with power C93∘C).
Yes, dry saunas can be good for your lungs if you have healthy airways or mild conditions like asthma or chronic bronchitis. The heat helps dilate airways, reduce inflammation, and improve lung capacity. However, the dry air can irritate airways, so they are not recommended if you have COPD, an active infection, or a cold.
Inducing mild heat-stress through the use of hot springs (balneotherapy), hot baths, saunas, steam-rooms and application of hot mud (pelotherapy), can be used to mimic fever and activate immune defenses.
To speed up recovery, hit the cold early at the first sign of symptoms. While there is no instant cure, you can significantly support your immune system and shorten the duration of your illness using proven methods.
Whether a sauna is bad for a cough depends entirely on the cause of your symptoms. If you have a mild, mucusy cough or congestion from a common cold, the heat can help loosen mucus and soothe your airways. However, if your cough is severe, is accompanied by a fever, or is dry and hacking, a sauna can make you significantly worse.
No, you cannot sweat out a virus. Sweating does not flush pathogens out of your system, and intentionally overheating yourself can actually make you sicker by causing dehydration.
Saunas cannot cure the flu or "sweat out" the virus, but they can temporarily relieve symptoms like congestion and muscle aches. While regular sauna use may help prevent illness by strengthening the immune system, using one while already sick with a high fever can be dangerous and is not recommended.
COVID-19 cannot spread through sweat itself. The virus is a respiratory illness primarily transmitted through airborne droplets. While sweat does not contain the live virus, it can become contaminated if an infected person touches virus-laden droplets and transfers them to surfaces.
Joe Rogan primarily uses traditional Finnish dry barrel saunas manufactured by Salus Saunas. He has these 6-person cedar barrel saunas installed at both his Austin home and his podcast studio, featuring high-powered heaters that reach up to 200°F.
The hottest saunas ever recorded reached staggering temperatures of 110°C (230°F) up to 150°C (300°F). These extreme temperatures were featured in the deadly World Sauna Championships (which were permanently shut down in 2010) or in record-chasing amateur smoke saunas. For context, standard saunas operate between 76°C and 93°C (170°F to 200°F).
Neither, as "better" is subjective and depends on whether you prefer intense, dry heat for detoxification (dry sauna) or lower-temperature, humid steam for respiratory relief and skin hydration (wet sauna/steam room). Dry saunas offer higher temperatures for muscle relaxation, while wet saunas are better for congestion and hydrating skin.
For sauna detoxification, aim for 15 to 20 minutes per session, building up to a maximum of 30 minutes for experienced users. Shorter, more consistent sessions (3 to 4 times a week) are much safer and more effective than one prolonged session.
Losing a pound in a sauna takes 15 to 60 minutes. However, this drop on the scale is entirely water weight and not actual fat. The weight will return as soon as you rehydrate.
After a sauna, you should focus on cooling down gradually, rehydrating with water or electrolytes, and resting to maximize benefits like improved circulation and deep relaxation. Key steps include taking a cold or lukewarm shower to rinse off sweat, wearing loose clothing, and avoiding intense activity for 10–20 minutes.
Your body constantly eliminates waste and environmental toxins through its natural filtration systems—primarily the liver, kidneys, and digestive tract. You can tell this process is active when you experience changes related to the excretion and breakdown of waste.
Scientific evidence does not show that saunas can eliminate actual microplastic particles from your body. While saunas offer great wellness benefits, they cannot "sweat out" solid plastic particles, as these particles are too large to pass through your skin's pores and sweat glands.
To maximize the health benefits of a sauna and avoid dangerous pitfalls, never stay inside for longer than 15–20 minutes, skip drinking water, or consume alcohol. Additionally, leave all electronics outside, and do not wear jewelry, heavy makeup, or lotions that can clog pores and damage equipment.
