Infrared saunas can harm individuals
Infrared Sauna Therapy info
Infrared sauna therapy immediately warms the body, relaxing it, improving circulation, and temporarily relieving pain, but it can harm individuals with heart disease, high blood pressure, pregnancy, or dehydration. It should never replace medical treatment and should be used safely.
What is Infrared Sauna Therapy?
- Traditional saunas heat the air, but infrared saunas heat the body directly.
- 113–140°F (45–60°C) is lower than regular saunas but still produces deep sweating.
- Promoted for relaxation, healing, and wellness.
Possible Benefits
- Heat increases relaxation and decreases stress chemicals.
- Relief: May help fibromyalgia, osteoarthritis, and low-back pain.
- Heat increases blood flow by expanding blood vessels.
- Some research supports psoriasis and skin renewal benefits.
- Reduces post-workout discomfort.
- Sleep and metabolism: Early studies suggest improvements, although evidence is weak.
Risks and Precautions
- Heart disease: Can strain the heart.
- Risks include dizziness and decreased blood pressure.
- Heat is dangerous during pregnancy.
- Sweating causes dehydration; drink water before and after sessions.
- Drug interactions: Diuretics and blood pressure medications increase risk.
Safe Use Guidelines
- Limit sessions to 15–20 minutes.
- Stay hydrated before and after.
- Avoid drinking beforehand.
- Stop feeling dizzy, faint, or nauseous.
- See a doctor for chronic problems.
Infrared vs. Traditional Sauna
- Infrared Sauna Traditional Sauna
- The body is heated directly by infrared light. Heating air warms the body.
- Lower air temperature (113–140°F). Higher ambient temperature (150–195°F)
- A better fit for heat-sensitive people. Higher heat exposure
- Evidence is scarce. Long-term research strength
Infrared saunas: how do they work?
- Instead of heating the air, infrared light penetrates the skin and warms tissues.
- At 120–140°F (49–60°C), it produces deep sweating, but the temperature is cooler than that of regular saunas.
Physiological response:
- Increased heart rate (like moderate exercise).
- Increased blood vessel dilation improves circulation.
- Sweating regulates body temperature but does not detoxify.
Proven Benefits
- Heat decreases stress and calms.
- Temporary muscle soreness, fibromyalgia, and arthritic pain alleviation.
- Circulation support: Better blood flow may aid exercise recovery.
- Sleep and wellness: Some users claim better sleep and wellness.
The drawbacks of an infrared sauna?
Healthy individuals can safely use infrared saunas, but they can cause dehydration, dizziness, nausea, weariness, and skin irritation. Too long, too hot, or with alcohol or certain drugs might cause fainting, burns, or blood pressure decreases.
Common Drawbacks
- Dehydration: Lose 300–700 ml per session. Dehydration causes headache, weariness, dry mouth, and dizziness.
- Orthostatic hypotension causes dizziness and lightheadedness. Standing up too soon after a session intensifies it.
- Heat stress can cause nausea, especially if dehydrated or utilizing the sauna after a big meal.
- Exhaustion: Mild post-session exhaustion is typical, but excessive fatigue indicates overheating or dehydration.
- Redness: Temporary erythema is normal; blistering indicates overheating.
Rare but Serious Risks
- Blockage of sweat glands causes heat rash.
- Hot surfaces or malfunctioning equipment cause burns.
- Overheating or blood pressure declines cause fainting and falls.
- Drug interactions: Diuretics, blood pressure medications, and heat-sensitive pharmaceuticals enhance hazards.
- Reproductive effects: Frequent users report temporary sperm count and motility decline.
Guidelines for safety
- If you sauna often, drink 500 ml water before and after each session and add electrolytes.
- Limit sessions to 15–20 minutes at 113–140°F (45–60°C).
- Do not drink alcohol or take drugs before your sauna session.
- After finishing, sit for 2–3 minutes before standing.
- Immediately stop if dizzy, faint, or nauseated.
- Consult a doctor if pregnant, have cardiovascular disease, or take hydration or blood pressure drugs.
Mild vs. Serious Drawbacks
- Possibility of mild effects and serious risks.
- Dehydration, fainting, falls
- Side effects: dizziness, burns
- Drug interactions and nausea
- Temporary sperm health alterations and fatigue
- Skin redness, severe hypotension
Side effects of infrared sauna
Dehydration, dizziness, nausea, weariness, and temporary skin redness are common adverse effects of infrared sauna therapy, but fainting, burns, and blood pressure reductions can occur if sessions are too lengthy, too hot, or mixed with alcohol or certain drugs. Avoid it if pregnant, dehydrated, or having a heart condition.
Typical Side Effects
- Headache, weariness, dry mouth, and dizziness can result from 300–700 ml of water loss every session.
- Orthostatic hypotension causes dizziness and lightheadedness.
- Nausea: Heat stress can cause stomach pain, especially after a big meal or dehydration.
- Fatigue: Mild post-session fatigue is typical; severe fatigue indicates overheating or dehydration.
- Skin redness: Vasodilation-induced erythema that fades in 30–60 minutes.
Infrared saunas hurt eyes
While infrared saunas do not release dangerous UV rays, prolonged exposure to heat and near-infrared light can cause dryness, discomfort, and even thermal damage to the retina or lens without proper eyewear. Saunas can harm glasses and contacts.
Infrared Sauna Eye Risks
The video explains the health benefits of an infrared sauna
- Heated tears evaporate faster, causing burning, redness, and impaired vision.
- Sweat and humidity increase bacterial risk; lenses may feel sticky or uncomfortable.
- Warped frames and lens coatings: High heat damages glasses.
- If overexposed, 700–1400 nm wavelengths can penetrate the eye and cause cataracts and retinal thermal damage.
Warning Signs to Stop Now
- Chronic eye discomfort or light sensitivity
- Sudden blurred vision or eye swelling
- Thick discharge or redness that continues after cooling
Guidelines for safety
- Safeguard your eyes using NIR-blocking glasses, not UV ones.
- Take out your contacts before entering.
- Limit sessions to 15–20 minutes.
- Stay hydrated before and after.
- Leave if eyes itch or vision changes.
Infrared sauna eyewear
Proper eye protection is crucial for infrared saunas because of the potential for dryness, discomfort, and even cataracts in rare situations. Consider using NIR-blocking glasses, colored goggles, or sauna-specific eye masks for safety. Standard UV sunglasses fail.
Why Protect Your Eyes
- IR light exposure: 700–1400 nm wavelengths penetrate the eye and cause retinal thermal damage and cataracts.
- Heat stimulates tear evaporation, causing discomfort and blurred vision.
- Individuals with ocular disorders or frequent sauna use are particularly susceptible.
Advice on Eye Protection
- NIR-blocking glasses: Special coatings block 780–1400 nm radiation, preventing eye tissue heat.
- Tinted goggles reduce eye strain and dryness, especially during extended sessions.
- Light-blocking eye masks: Completely shield eyes for comfort.
- Infrared-blocking sauna glasses: Comfortable and protective.
Guidelines for safety
- Sauna entry requires contact lens removal.
- To reduce cumulative exposure, limit sessions to 15–20 minutes.
- Do not stare at infrared heaters.
- Stay hydrated to avoid dryness.
- Those with glaucoma or cataracts should see an eye doctor.
Comparing Options
- Effectiveness of Protection Type: Comfort is best with NIR-blocking lenses. Medical safety: high, moderate, frequent users
- Tinted goggles: medium-high relaxation, dryness prevention.
- Eye masks: High, Very High. Full relaxation, sensitive eyes
- Regular UV sunglasses: Low, Moderate, or Not Recommended (no NIR protection).
Conclusion:
Rest, transient pain alleviation, and healing are the key benefits supported by research. Dehydration, dizziness, eye irritation, and dangers for heart disease, pregnancy, and certain drugs are also risks.
Infrared saunas can improve well-being but not detox when used safely—15–20 minutes per session, sufficient hydration, and protective eyewear if needed.
