A: Yes. A peer-reviewed study using EEG, HRV, and CPC analysis confirmed significant improvements in sleep quality, deep sleep duration, and autonomic nervous system balance. NASA also uses Schumann generators in space shuttles. Q: How long does it take to see effects? A: Many users report feeling calmer within days. The clinical study measured improvements over 5 days — with LF/HF ratio normalizing and HRV improving. Q: Where should I place it? A: Place within 18 square meters of your living/sleeping area. Recommended height: ~1.5 meters above floor. For large spaces, multiple units may be needed. Q: Is it safe? A: Yes. The output is extremely low-power ( Q: What’s the difference between this and a meditation app? A: Apps use audio. This uses electromagnetic fields — a different pathway that works even when you‘re asleep. They can be used together. Q: Does it work for everyone? A: Most users benefit, but effects vary. Extremely noisy electromagnetic environments or highly excited/anxious states may reduce effectiveness. Q: Can I adjust the frequency? A: Yes — from 0.01Hz to 100kHz. 7.83Hz is the default Schumann frequency. Advanced users can explore other frequencies for research or custom applications. Q: Does it need to be on 24/7? A: For best results, many users leave it on continuously. Power consumption is very low ( Size: Without shell 100 * 70 * 8mm With shell: 107 * 77.5 * 18mmPackage Include: 1X Schumann wave generator module 1X power cord
