"For almost three years, I had no idea what was happening to me. Constant exhaustion, brain fog, waking up feeling worse than when I went to bed. I went from doctor to doctor โ nobody connected the dots."
When I finally got a sleep study, the result stopped me cold. Out of 9 hours in bed, I had stopped breathing for a total of 4.5 hours โ with individual pauses lasting over 1 minute 40 seconds. An AHI of 88. My body had been suffocating, silently, every single night, and I had no idea. The specialist told me that had I waited another year, I would have been on blood pressure and cardiac medication for life.
I built this test because no one should spend 2โ3 years searching for an answer that a handful of the right questions can surface in minutes. The signs were all there โ I just didn't know what to look for. Time is everything when it comes to sleep apnea.

โ ๏ธThis screening is not a medical diagnosis. It is based on validated clinical risk factors (STOP-BANG, Epworth, Berlin questionnaires) and patient-reported symptoms from published research. The only way to confirm sleep apnea is a polysomnography sleep study. If you scored moderate or higher, please discuss with your doctor.

What healed in your body?
Click an organ to see how sleep apnea affected it โ and how it recovered.
๐ง Brain & Cognitionโ Recovered
During untreated apnea, the brain was repeatedly starved of oxygen 88ร per hour. This impaired memory consolidation, decision-making, and mood regulation. After 9 months: reaction time improved, brain fog cleared, morning headaches gone. Deep sleep โ the brain's "cleaning cycle" โ tripled from 6% to 22% of each night.
โค๏ธHeart & Blood Vesselsโ Recovered
Each breathing stop triggered a surge of adrenaline and blood pressure spike โ up to 88ร per night. Over time this strains the heart muscle and arterial walls. HRV (heart resilience score) tripled from 18ms to 61ms. Resting night heart rate dropped from 74 to 62 bpm, reducing long-term cardiovascular risk significantly.
๐ซLungs & Breathingโ Recovered
The lowest blood oxygen at night was 77% โ well below the safe threshold of 90%. The CPAP created continuous positive air pressure, keeping the airway physically open. Blood oxygen recovered to 96% by Month 9. The number of oxygen-dip events dropped from 142 to just 3 per night.
๐ฅMetabolism & Blood Sugarโ Improving
Sleep apnea disrupts the hormones that regulate hunger and blood sugar. HbA1c was at 5.8% (borderline) and improved to 5.3% (normal) without dietary changes โ simply from better sleep. CRP inflammation dropped 73%, reducing the metabolic stress load on liver and pancreas.
๐ซKidneys & Blood Pressureโ Recovered
The kidneys regulate blood pressure partly through night-time rest cycles. Untreated apnea causes nocturnal hypertension โ high blood pressure specifically at night when it should be lowest. As therapy progressed and stress hormone (cortisol) dropped from 22.1 to 12.4 ฮผg/dL, the kidneys' nightly workload normalised.
What this means for your future health
Based on the data โ translated into real-world health risk.
โค๏ธ
Heart attack & stroke risk
Before: 3ร higher riskโNow: Normal range
Untreated severe apnea (AHI 88) is linked to 3ร higher cardiovascular event risk. With AHI now at 6, this excess risk is largely eliminated. The 88โ6 improvement is clinically significant.
๐ง
Dementia & cognitive decline
Before: ElevatedโNow: Reduced
Chronic oxygen deprivation during sleep accelerates brain aging. Deep sleep โ where the brain's waste-clearing system (glymphatic system) works โ tripled. This is protective against long-term cognitive decline.
๐ฉบ
Type 2 diabetes risk
Before: BorderlineโNow: Normal
HbA1c dropped from 5.8% (pre-diabetic range) to 5.3% (normal) through sleep treatment alone. Sleep apnea directly impairs insulin sensitivity โ fixing the sleep fixed the metabolic problem.
๐
Mental health & mood
Before: DepletedโNow: Stable
Fatigue dropped from 9/10 to 2/10. Sleep quality from 2/10 to 9/10. Chronic sleep deprivation is a primary driver of depression and anxiety. Restoring deep sleep is one of the most effective mood interventions possible.
๐ฅ
Chronic inflammation
Before: Very high CRP 8.4โNow: 2.3 mg/L (โ73%)
High CRP accelerates atherosclerosis, cancer risk, and autoimmune conditions. Without changing diet or medication, CRP fell 73% โ purely from treating the sleep disorder that was inflaming the body every single night.
