H-Core for Insomnia — Understand and Improve Sleep with Real Data
Not sleeping less — sleeping wrong
30–45% of Vietnamese adults have sleep problems. Most don't know they're lacking deep sleep, or that their SpO₂ drops at night, or that their HRV is too low for recovery. H-Core gives you concrete data — not feelings, but real numbers — to understand the actual problem and make effective changes.
The challenges you face
Lying awake unable to sleep — low HRV and high cortisol
Difficulty falling asleep is usually a sign your nervous system hasn't entered a relaxed state. Low HRV and high resting heart rate are objective evidence. H-Core measures both every night so you can see the pattern clearly.
Waking repeatedly at night without knowing why
Waking frequently at night can be due to SpO₂ drops (mild apnea), heart rate spikes, or transitions between sleep stages. H-Core records detailed hourly charts to help identify the exact cause.
Tried everything but can't tell what actually works
Herbal tea, early lights out, pre-sleep meditation — but do you know which one actually improves your deep sleep? Long-term data from H-Core helps find the correlation between habits and recovery quality.
