Infrared saunas are generally safe, but heat stress and elevated core temperatures carry strict medical contraindications. Individuals with pacemakers, severe cardiovascular disease, multiple sclerosis, or active infections/fevers should avoid use. Pregnant women and young children should also avoid use without prior medical clearance.
Individuals with circulatory issues, reduced sensitivity to heat, disrupted ability to sweat, or a predisposition to bleeding may not respond safely to the heat stress of an infrared sauna.
Yes, saunas are a highly effective natural tool for managing high cortisol. While the intense heat initially spikes the stress hormone as your body adapts to thermal stress, regular sessions—specifically infrared or traditional saunas—lead to significantly lower baseline cortisol levels and better long-term stress management.
Yes, using the sauna while taking creatine is perfectly safe and highly beneficial for recovery. Creatine does not dehydrate you. Instead, it drives water into your muscle cells and can actually help your body tolerate heat stress better.
Yes, you can typically use an infrared sauna with titanium implants. Because titanium effectively reflects far-infrared waves rather than absorbing them, the implants will not heat up to dangerous levels like other metals might.
Stepping into a soothing infrared sauna experience elevates core temperature through deep‑penetrating far infrared waves. This increase in circulation can enhance detox-like benefits, support skin clarity, and ease muscular tension. Some of these perks include: Improved cardiovascular response and relaxation potential.
You can use a sauna after a knee replacement, but only after your surgical incision is completely healed and you have been cleared by your surgeon. This typically takes about 6 to 8 weeks. Using a sauna too early carries major risks of infection and can worsen post-surgical swelling.
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%.
Spending 20 minutes in a sauna triggers a healthy cardiovascular response by elevating your heart rate and dilating blood vessels, which improves circulation, flushes toxins through deep sweating, and promotes muscle recovery. It also acts as a profound stress-reliever, triggering endorphins to help your body unwind.
Yes, saunas can be highly beneficial for joint pain. Research indicates that regular sessions—whether in traditional or infrared saunas—reduce pain, decrease stiffness, and improve mobility for conditions like osteoarthritis and rheumatoid arthritis.
This rise in hormones changes your appetite. You do not usually crave broccoli or grilled fish when you are stressed. Instead, you want foods that give you fast energy or make you feel comforted. Most people crave sugar, salt, and fat when their cortisol stays high for too long.
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.
When cortisol (the primary stress hormone) remains elevated for too long, it impacts your metabolism, blood pressure, and immune system. Here are 10 common warning signs of chronically high cortisol levels:
Overheating and dehydration
The primary risk of either a dry or steam sauna or infrared cabin is overheating, as explained by physician Andrew Weil. Overheating can lead to fainting and dehydration. Older people are more prone to overheating because sweat gland function decreases with age.
Many studies have looked at using infrared saunas in the treatment of long-lasting health problems and found some proof that saunas may help. Conditions studied include high blood pressure, heart failure, dementia and Alzheimer's disease, headache, type 2 diabetes, and arthritis.
Yes, sauna use is generally safe for people with controlled or stable high blood pressure, and can even offer cardiovascular benefits. However, the heat puts a load on your heart, making precautions vital.
Yes, you should hydrate during a sauna visit, but avoid drinking while sitting inside the hot room. Chugging ice-cold water in high heat can shock your system. Instead, step out into a cooler area during breaks to sip room-temperature water or an electrolyte drink.
The heat helps ease muscle tension while nudging your nervous system out of fight-or-flight mode. It also sparks the release of endorphins — natural mood boosters — leaving you calmer and more at ease. “There's also a mental clarity that comes with it,” says Guarco.
Saunas trigger deep sweating, which helps your body naturally excrete a variety of impurities and metabolic byproducts. The primary toxins and substances released through post-sauna sweat include:
Yes, regular sauna use helps lower cortisol, but the process has two distinct phases:
30 minutes in a sauna is physiologically comparable to light cardio, such as a brisk walk, light cycling, or moderate calisthenics.
For the best health benefits, aim for a traditional sauna temperature between 150∘F150 raised to the composed with power F150∘F and 175∘F175 raised to the composed with power F175∘F (65∘C65 raised to the composed with power C65∘C to 80∘C80 raised to the composed with power C80∘C). For infrared saunas, a lower range of 120∘F120 raised to the composed with power F120∘F to 145∘F145 raised to the composed with power F145∘F (48∘C48 raised to the composed with power C48∘C to 63∘C63 raised to the composed with power C63∘C) is standard. The sweet spot to trigger deep healing and cellular repair is a core body temperature rise of about 1∘F1 raised to the composed with power F1∘F to 2∘F2 raised to the composed with power F2∘F.
High-impact activities or contact sports such as football, skiing or lifting heavy weights are best avoided throughout your knee replacement recovery period. They carry a high risk of falling which can damage your new joint.
Sauna for Joint Pain and Inflammation
Research shows that regular sauna use can reduce joint stiffness, decrease pain intensity, and improve overall mobility in patients with inflammatory arthritis.
ACL reconstruction surgery is commonly performed to repair a torn anterior cruciate ligament (ACL) in the knee. Recovery from this orthopedic surgery can be challenging due to the knee's complexity and frequent use in daily activities.
