Who Should Not Use an Infrared Sauna?

Infrared saunas have grown in popularity for their potential benefits—relaxation, muscle recovery, improved circulation and more. They work by emitting infrared light that heats your body directly, rather than warming the air around you. Although many people tolerate this form of heat therapy well, certain groups should avoid or take special precautions before using an infrared sauna.

Always remember: if you have any life-threatening or serious symptoms, speak to a doctor immediately. You can also consider a free, online symptom check, using the doctor approved Ubie Symptom Checker to guide your next steps.

1. Cardiovascular Conditions

Infrared saunas raise heart rate and dilate blood vessels, which can put extra strain on your heart and circulation.

• Uncontrolled high blood pressure (hypertension)
• Recent heart attack or stroke (within the last 6 months)
• Severe coronary artery disease or angina
• Heart failure or cardiomyopathy

People with these conditions may experience dizziness, a sudden drop in blood pressure, or chest pain when exposed to prolonged heat. Always get medical clearance before trying an infrared sauna if you have cardiovascular concerns.

2. Pregnancy

Pregnant women are generally advised to avoid any activities that significantly raise core body temperature. Excessive heat in early pregnancy has been associated with neural-tube defects and other complications.

• First trimester—critical period for fetal development
• Any history of miscarriage or high-risk pregnancy
• Multiple gestation (twins, triplets)

If you’re pregnant and curious about infrared saunas, discuss it with your obstetrician. They can help you weigh any potential benefits against risks to you and your baby.

3. Implantable Medical Devices

Infrared saunas can interfere with certain electronic or heat-sensitive implants.

• Pacemakers or defibrillators
• Insulin pumps
• Neurostimulators (e.g., spinal cord stimulators)
• Certain metal implants (joint replacements, pins, screws)

The sauna’s electromagnetic fields and heat could affect device function or accelerate corrosion of metal hardware. Always check with your device manufacturer or healthcare provider before using an infrared sauna.

4. Skin Conditions and Open Wounds

Infrared heat increases skin blood flow and can aggravate some dermatological issues or slow wound healing.

• Eczema, psoriasis or severe acne flares
• Recent burns, cuts or surgical wounds
• Active infections (cellulitis, fungal rashes)

Heat may intensify itching, dryness or inflammation. If you have a chronic skin condition, consult a dermatologist to determine if infrared therapy is right for you.

5. Medications and Heat Sensitivity

Some drugs alter your body’s ability to sweat or regulate temperature, increasing the risk of overheating, dehydration or low blood pressure.

• Diuretics (“water pills”)
• Beta-blockers and calcium-channel blockers
• Antipsychotics and some antidepressants
• Anticholinergics (used for overactive bladder, Parkinson’s disease)
• Stimulants (for ADHD or weight loss)

Review your medications with your physician or pharmacist. They can advise if infrared sauna sessions are safe or if you need adjusted timing, dosage or extra hydration.

6. Neuropathy and Impaired Heat Sensation

People who cannot fully feel or react to heat face a higher risk of burns and overheating.

• Diabetic peripheral neuropathy
• Spinal cord injuries
• Multiple sclerosis with sensory loss
• Severe peripheral vascular disease

If you have reduced sensation in your limbs or trunk, you may not notice dangerously high temperatures. Consider shorter sessions at lower temperatures or supervised use in a clinic setting.

7. Children and Older Adults

Thermoregulation (body’s ability to maintain temperature) varies with age.

Children under 12
• Still developing temperature-regulating systems
• Higher surface-area-to-body-mass ratio—heat up faster

Adults over 65
• Reduced sweating and circulation
• Commonly on multiple medications affecting heat tolerance

Both groups should use extreme caution. If you’re considering an infrared sauna for a child or older adult, seek pediatric or geriatric advice first.

8. Chronic Illnesses and Autoimmune Disorders

While some proponents claim relief for conditions like rheumatoid arthritis or lupus, others may experience flares or complications.

• Systemic lupus erythematosus (risk of increased photosensitivity)
• Rheumatoid arthritis during active joint inflammation
• Fibromyalgia with heat-triggered pain
• Chronic fatigue syndrome (risk of post-exertional malaise)

Talk to a rheumatologist or your specialist before regular infrared sauna use. They can help monitor your response and adjust your treatment plan safely.

Safe Practices and Precautions

If you’re generally healthy but new to infrared saunas, follow these guidelines:

• Start slow: 5–10 minutes at lower temperatures (100–120°F)
• Hydrate: drink water before, during and after your session
• Cool down: allow your body to return to normal temperature gradually
• Listen to your body: exit the sauna at any sign of dizziness, nausea or extreme discomfort
• Supervision: use public or clinical saunas with staff trained in first aid

When to Seek Professional Advice

Even if you don’t fall into a high-risk category, it’s wise to consult a healthcare provider if you:

• Have unexplained chest pain, shortness of breath or fainting
• Experience severe skin reactions or rashes after heat exposure
• Take medications that affect heart rate, blood pressure or fluid balance
• Are preparing for surgery (implants, anesthesia concerns)

You might also try a free, online symptom check, using the doctor approved Ubie Symptom Checker to better understand any warning signs before booking an infrared sauna session.

Final Thoughts

Infrared saunas offer potential benefits, but they aren’t risk-free. If you have any of the conditions listed above—or if you’re unsure—always:

1. Speak to your doctor for personalized medical advice
2. Disclose all medical history, devices and medications
3. Follow safe-use guidelines: shorter sessions, lower temperatures and plenty of fluids

By taking these precautions, you can make informed decisions and protect your health while exploring what infrared saunas have to offer.
