photon-light application lowers stress-linked heart rate variability ratio, supporting autonomic balance in poor sleepers
Laser acupuncture treatment significantly reduced the LF/HF ratio in heart rate variability in chronic insomnia patients, indicating restoration of autonomic balance with suppressed sympathetic tone.
What this means for you
Your nervous system has two modes — 'go' and 'rest.' In people with chronic sleep trouble, the 'go' mode stays on too long. This finding shows that photon-light application helped shift that balance back toward calm, which is exactly the physiological state your body needs to fall and stay asleep.
