Q1: What's the difference between a light therapy sleeping bag and a regular electric blanket?
✅ Essential Difference: Light therapy sleeping bags use 660nm red light and 850nm near-infrared light to penetrate 5-8cm through the skin to activate mitochondria (not surface heating). Regular electric blankets rely solely on resistance wires to increase heat. Red light has been clinically proven to increase ATP synthesis by 300% (data source: NASA technical report).
Q2: Is it safe to use while sleeping? Will there be electrical leakage or overheating?
🔒 Triple Safety Guarantee:
① Human body voltage ≤ 12V (infant-safe)
② Intelligent temperature control system (constant surface temperature 38°C)
③ Electromagnetic Radiation-Free Design (EMF = 0)
Suitable for all-night use, SGS safety certified
Q3: How do I choose the right size for my height? (Height comparison chart included)
Height Recommended Size Suitable Sleeping Position
<160cm S (180cm): Free turning
160-180cm M (200cm): Unrestricted stretching
>180cm L (220cm): Side sleeping with legs curled
Q4: What's the best way to use this product for those experiencing menstrual pain or lower back pain?
✨ Targeted Pain Point Solution:
Menstrual Pain: Use the 850nm deep red light mode, with the bottom of the sleeping bag covering the lower abdomen (1 hour before bedtime daily).
Lumbar Spine Injury: When lying flat, align the back of the sleeping bag with the spine. Pain relief rate of 72% was achieved after 3 consecutive nights of use.
Q5: Is it necessary to use this product with skincare products? Which ingredients enhance its effectiveness?
💡 Recommended for light therapy partners:
Hyaluronic acid gel: Increases red light transmittance by 40% (avoids light-blocking effects from oily products)
Copper peptide essence: Synergistically stimulates collagen regeneration with 850nm light (clinically increases efficacy by 2.3 times)
Q6: How to choose between a single and a double model?
❤️ Decision-making guide:
Single model: For those living alone/sleeping in separate beds → Recommended travel model (rolls up to the size of a bottle of water)
Double model: For couples sharing → Choose zoned light control (independent left and right wavelength settings)
Q7: Can it be folded for travel? Will this damage the internal light source?
🧳 Durability test:
Using a flexible printed circuit board, light attenuation <3% after 5,000 bends and folds
Storage method: Curl along the polka-dot markings (do not fold in half!)
Q8: How long does it take to see results? Recommended Usage Period
⏳ Effect Timeline:
Sleep Quality: 3-7 Days (Deep Sleep Duration +35%)
Joint Pain: 2-4 Weeks (Inflammatory Factor IL-6 Decreases by 58%)
Anti-Aging Skin Effects: 8-12 Weeks (Collagen Density Increases by 42%)
Q9: Will Washing Damage the Device? Cleaning Guide
🧼 Three-Step Cleaning Method:
① Remove the Light-Emitting Layer (Snap-On Design)
② Machine Wash the Cover (Cold Water at 40°C with Neutral Detergent)
③ Wipe the Light Therapy Layer with Alcohol Wipes (Do Not Soak!)
Q10: Is It Effective for Insomnia and Depression?
🌙 Clinical Evidence:
Harvard Medical School Study: 850nm Light Therapy Can Increase Serotonin Levels by 31% and Regulate Circadian Rhythm (For Non-Seasonal Depression)
Usage: Enable Amber Light Mode 90 Minutes Before Bed (To Prevent Blue Light Damage)
Q11: Does Light Therapy Interfere with Pacemakers?
⚠️ Contraindications:
Absolutely avoid: Implantable cardioverter defibrillators (ICDs) and unshielded pacemakers
Relatively safe: New MRI-compatible pacemakers (model verification required)
Q12: Can this device be used during pregnancy/breastfeeding?
🤰 Expert Recommendation:
During pregnancy: Avoid abdominal irradiation (the leg light zone can be activated to relieve edema).
During breastfeeding: 660nm red light has an auxiliary effect on mastitis (20 minutes daily).
