- Small studies show reduced sleep-onset time and improved sleep quality, especially in anxious users.
- Devices are generally safe, with tingling and mild discomfort as the most common complaints.
- Evidence remains preliminary — no large-scale trials yet confirm strong benefits for insomnia.
- Treat these as early-adopter gadgets: low risk, uncertain benefit, and not a substitute for proven treatments.
