Sleep Disorders: India's Silent Health Epidemic Affecting Millions
Doctors routinely check blood pressure, diabetes, and cholesterol levels during medical examinations. However, they rarely ask a crucial question that could be equally important for overall health: how well are you sleeping? As the world observed World Sleep Day on March 13, medical experts issued urgent warnings that sleep disorders may be affecting millions of Indians while quietly elevating the risk of serious health conditions including heart disease, diabetes, and clinical depression.
Alarming Statistics Reveal Widespread Problem
New research confirms the extensive scope of this health crisis. A comprehensive 2025 systematic review published in the Indian Journal of Public Health analyzed 100 studies involving nearly 68,000 participants and discovered that 25.7% of Indians suffer from insomnia, while obstructive sleep apnea (OSA) affects approximately 37.4% of the population. Additionally, about 10.6% experience restless leg syndrome, a neurological condition that significantly disrupts sleep patterns.
Among patients already diagnosed with other medical conditions, the burden of sleep disorders appears even more severe. Research indicates that nearly 48% of these patients have sleep apnea, while 32% struggle with insomnia, suggesting that sleep disorders may actively worsen chronic diseases. Experts estimate that approximately 52 million working-age Indians may have sleep apnea, including nearly 29 million individuals suffering from moderate-to-severe forms of the disease. Insomnia affects nearly 37% of older adults in India.
Modern Lifestyle Factors Exacerbating Sleep Crisis
Professor (Dr) J C Suri, Director and Head of the Department of Pulmonary, Critical Care and Sleep Medicine at Sitaram Bhartia Institute of Science and Research, emphasized that contemporary lifestyle habits are significantly worsening India's sleep crisis. A revealing survey of IT professionals conducted in Hyderabad found that 97% used electronic devices for at least one hour before bedtime, while 62% reported persistent difficulty falling asleep or staying asleep throughout the night.
Dr Vikram Sarbhai, President of the Indian Sleep Disorders Association, stated: "Sleep deprivation is perhaps the world's biggest silent epidemic and has been worsening for decades, driven by our shift to a 24-hour society since the advent of electric lighting." He further explained that humans follow a circadian body clock that regulates sleep and wake cycles, making quality sleep essential for restoring both brain and body functions.
Dr Sarbhai emphasized that healthy sleep depends not only on duration but also on quality and regular timing, all of which are increasingly disrupted by modern lifestyles, shift work patterns, and excessive technology use. Typically, adults aged 18-45 years require 6-8 hours of sleep, those between 45-70 years need about 5-7 hours, and individuals aged 70 and above require approximately 5 hours. These estimates apply to individuals without excessive alcohol or caffeine consumption, toxic exposures, behavioral disturbances, or medical conditions that specifically affect sleep.
Broader Health Implications and Safety Concerns
The sleep crisis in India may be even more extensive than current data suggests. A 2025 report by AGR Knowledge Services estimates that three out of five Indians are sleep deprived, with many turning to online remedies instead of seeking proper medical diagnosis and treatment.
Professor (Dr) J C Suri highlighted that poor sleep quality is closely linked to numerous serious health conditions including hypertension, heart disease, stroke, diabetes, obesity, depression, and cognitive decline. Beyond individual health impacts, sleep deprivation is emerging as a significant road safety hazard. Studies conducted by the Central Road Research Institute discovered that approximately 40% of accidents on the Agra-Lucknow expressway were linked to driver fatigue caused by inadequate sleep.
Despite these substantial risks, India currently lacks any national policy mandating screening for sleep disorders among commercial drivers, unlike countries such as the United States, the United Kingdom, and Japan which have implemented such safety measures. Medical experts note that poor public awareness combined with the absence of sleep medicine in most medical school curricula means many patients with sleep disorders remain undiagnosed and untreated. Addressing sleep disorders comprehensively could represent a major but frequently overlooked opportunity in preventive healthcare across India.
