1. What is the QuasarMD Full Body Light Therapy Sleeping Bag and how does it work?

The Sleeping Bag is a full-body wrap style light-therapy device designed to deliver red (660 nm) and near-infrared (850 nm) light wavelengths simultaneously across your body. It uses thousands of LED beads embedded in the fabric to penetrate deep into muscles, joints and tissue — supporting circulation, reducing inflammation, aiding recovery and improving sleep quality.

2. What benefits can I expect from using it?

• Full-body muscle and joint recovery: the wrap-around design covers your entire body at once.
  
• Improved sleep and rest: the light therapy supports melatonin production and helps your nervous system relax.
  
• Skin health, circulation, metabolism: regular sessions support skin rejuvenation, better blood flow, and general wellness.
  

3. What are the recommended usage guidelines?

• Start with sessions of 15-30 minutes, about 3-4 times per week.
  
• It is recommended not to use the Sleeping Bag for more than 30 minutes at a time without break.
• For recovery or sleep support, most users find 20-30 minutes in the evening works well.
  
• Always lie down flat, relax while the device works, and follow safety settings.
  

4. What safety precautions should I take?

• Ensure you’re using the bag on an appropriate surface and with adequate ventilation — avoid heavy blankets that may trap heat.
  
• Protect your eyes if the light comes near your face; avoid direct eye exposure or use protective eyewear.
  
• 
  
• If you are pregnant, have a serious medical condition, have photosensitivity, or take medication that increases light sensitivity, please consult your physician before use.
  
• Although the device is built with safety controls (cool-to-touch materials, regulated LEDs), always monitor how your body responds during your first sessions.
  

5. How does the Sleeping Bag differ from a light therapy mat or panel?

• 
  
• Unlike a mat which you lie on, the Sleeping Bag wraps you around in a “bag” style, offering 360° full-body coverage — light exposure from more angles.
  
• Because it covers you entirely, you don’t need to turn over or reposition for full coverage.
  
• It’s more relaxing and convenient for full-body recovery or sleep support compared to standing/sitting in front of a panel.
  

6. When will I see results?

• Some changes — such as feeling more relaxed, improved sleep or reduced soreness — may be noticed within a few sessions.
  
• For more visible changes (e.g., skin texture improvement, deep-tissue recovery) consistent use over several weeks is recommended. Patience and regularity matter.
  
• Keep track of your sessions and any changes in how you feel to get a better sense of your progress.
  

7. What are the technical specifications and product details?

• Wavelengths: 660 nm + 850 nm dual wavelength.
  
• LED Count: 1026 @ 660 nm + 1026 @ 850 nm = total approx 2,056 LEDs.
  
• Irradiance: up to ~120 mW/cm² @ 0" (for full-body model).
  
• Dimensions: approx 71" x 23" (may vary).
  
• Weight: ~20 lbs (approx).
  
• Warranty: 1 year standard.
  
• 
  
• Lifetime: ~80,000 hours LED lifespan.
  

8. How should I set it up and place it for optimal results?

• Lay the sleeping bag on a flat surface — bed frame, mattress, floor — ensuring it’s smooth and free of ridges.
  
• Slip inside the bag so your body is evenly wrapped; you may zip it up if the design allows.
  
• Lie still for the session, relax, minimize movement and let the light do the work.
  
• You may combine with quiet reading, audio meditation or pre-sleep relaxation.
  

9. Are there any reported negative effects or risks?

• The device is generally considered safe when used as directed. However:
• 
  
• 
  
• Some users may feel mild warmth or slight redness shortly after use — this is normal and typically resolves quickly.
• 
  
• 
  
• Using for too long, or under heavy blankets without ventilation, may cause overheating or discomfort.
• 
  
• 
  
• If you feel discomfort, dizziness, or any adverse reaction, stop use and consult a healthcare professional.
•

10. What should I look for when purchasing a light therapy sleeping bag?

• Verified dual-wavelength (660 nm & 850 nm) output for broad performance.
  
• High LED count / dense matrix for full-body coverage.
  
• Proper safety certifications, clear usage instructions and warranty.
  
• Ease of set-up, comfortable material design and solid manufacturer support. The QuasarMD Sleeping Bag meets these criteria and is positioned as a professional-grade home-use device.
