It is a clinical issue — invisible, under-diagnosed, and responsible for a cascade of cardiovascular, metabolic, and psychiatric disease affecting hundreds of millions of Indians.
A sleep study measures all four of these parameters simultaneously. Most Indians have never had one.
Every organ system is harmed by fragmented or insufficient sleep. The science is unambiguous — and India's clinical infrastructure is almost entirely absent.
Chronic sleep deprivation elevates cortisol and inflammatory markers — CRP and IL-6 — accelerating atherosclerosis. Obstructive sleep apnea independently confers a 2–3× increased risk of hypertension and atrial fibrillation.
Cappuccio et al., European Heart Journal, 2011Compared to Singapore, Japan, and the United States, India is almost entirely without the diagnostic foundation that sleep medicine requires. The average wait time for a full overnight sleep study in a metro city is 6–8 weeks — if a facility can be found at all.

Sleep Hemisphere is built on the same evidence base that drives AASM-accredited sleep medicine globally — precision diagnostics, evidence-based therapeutic protocols, and AI-augmented longitudinal monitoring. Three layers. One integrated system.
A full overnight sleep study measures exactly what is happening while you sleep — how long you spend in each stage, how many times your breathing is disrupted, your blood oxygen levels, and how your body moves. This gives us the clinical baseline from which all treatment decisions are made.
Polysomnography · Home Sleep Test · AHI ScoringCBT-I — Cognitive Behavioural Therapy for Insomnia — is the AASM's first-line recommended treatment, achieving 70–80% durable remission at 6 months. CPAP titration eliminates upper-airway obstruction in sleep apnea. Every protocol is mapped to the peer-reviewed evidence base.
CBT-I · CPAP Titration · Pharmacological ProtocolsBetween clinic visits, a wearable device tracks your blood oxygen, heart rate, and movement every night. An AI system analyses this data and flags signs of disrupted sleep — so your care team can adjust your treatment based on what is actually happening, not just what you remember.
Wearable Monitoring · AI Sleep Analysis · Remote ReviewClinical evidence now confirms the bidirectional relationship. Treating sleep first improves psychiatric outcomes — and untreated sleep disorders reliably worsen them.
Insomnia independently doubles the risk of developing major depressive disorder. 75% of depressed patients report chronic insomnia. Treating sleep first improves antidepressant response rates.
Ford & Kamerow, JAMA (1989); Baglioni et al., J. Affect. Disord. (2011)Sleep deprivation amplifies amygdala reactivity by 60%, heightening threat perception and fear generalisation. CBT-I targeting sleep reduces anxiety severity scores by 30–40%.
Yoo et al., Current Biology (2007)Sleep disturbance is the most reliable prodrome of manic relapse — present in 75% of cases before an episode. Circadian stabilisation is a primary treatment target.
Jackson et al., J. Abnorm. Psychol. (2003)REM sleep fragmentation is central to PTSD pathophysiology. Disrupted REM impairs fear extinction consolidation — the brain's natural mechanism for processing trauma.
Walker & van der Helm, Neuron (2009)Insomnia is an independent risk factor for suicidal ideation with 2.7× increased odds — over and above depression severity alone. Sleep is an underutilised intervention target.
Peer-reviewed clinical epidemiologyOver 80% of patients with schizophrenia show sleep architecture disruption. Improving sleep quality independently predicts better psychosocial functioning and reduced hospitalisation.
Clinical sleep architecture literatureYou arrive at any of our four Delhi-NCR clinics — by referral or on your own. A structured intake assessment captures your full sleep, medical, and lifestyle history. No tests yet, just a thorough conversation with a clinician.
The screening findings are combined with data from any wearable you already use — Fitbit, Apple Watch, Garmin, or any other device. The result is a full, personalised picture of your sleep: what is disrupted, how severely, and what is driving it.
Based on your report, a treatment plan is assigned — CBT-I for insomnia, CPAP or BiPAP for breathing-related disorders, pharmacological support, or a combined approach. Every protocol is evidence-based and reviewed by a clinician throughout.
Between visits, your wearable continues feeding data to our AI system — tracking sleep quality night by night. Works with whatever device you already own. If your sleep changes between appointments, your care team knows before your next visit.
The Sleep Hemisphere integrates comorbid psychiatric screening into every patient pathway. Our psychiatry collaboration enables sleep-first interventions that reduce psychiatric relapse — and prevents the circular pattern of treating mental health without addressing the sleep disorder driving it.
"Treating insomnia is, in many patients, the most important clinical intervention available."
Consultant physician driving patient protocol design and diagnostic workflow management. The primary interface between the advisory board and frontline care delivery — ensuring every clinical pathway reflects current evidence standards.

Leads the hub-and-spoke rollout, corporate partnerships, and capital deployment planning. Responsible for translating clinical infrastructure into an operationally scalable enterprise across the NCR and beyond.
A Sleep Hemisphere assessment is a clinical evaluation. We measure what is actually happening in your sleep, and we address what is disrupting it.
