What was once automatic has become a choice we're losing
As World Sleep Day arrives, India finds itself second only to Japan in a quiet epidemic that unfolds not in hospitals but in bedrooms: between 70 and 80 percent of the country's youth are sleeping far less than their bodies require. The culprit is not hardship in the traditional sense, but the glowing screens that have colonized the hours once given to rest, suppressing the hormones that guide the body toward sleep and replacing natural rhythms with artificial stimulation. What is lost in those missing hours — attention, memory, resilience — accumulates silently, shaping the minds and futures of an entire generation.
- India now ranks second globally in sleep deprivation, with the vast majority of young people running on six or seven hours of fragmented rest instead of the eight to ten their developing minds and bodies demand.
- Smartphones, late-night gaming, and streaming platforms are actively suppressing melatonin production, rewiring the brain's natural wind-down signals and pushing sleep onset later and later into the night.
- Even a single night of inadequate sleep strips nearly 30 percent from a student's attention span — a deficit that compounds across weeks and months into measurable academic and cognitive decline.
- Sleep coaches and public health advocates are moving into schools and communities with programs on digital habits and sleep hygiene, but the pull of devices and academic pressure continues to outpace awareness.
- The crisis resists easy recognition because its costs are deferred — the teenager scrolling at midnight feels fine until the exam, the all-nighter's damage invisible until it has quietly accumulated into something harder to reverse.
On the eve of World Sleep Day, a troubling pattern has settled over India's cities: the country now ranks second only to Japan in sleep deprivation, and the cause is hiding in plain sight. Between 70 and 80 percent of young Indians — students and early-career professionals alike — are sleeping just six or seven hours a night, often at irregular times that leave them foggy and struggling to focus.
Sleep coach Archna Sharma traces the disruption to the devices that have become inseparable from daily life. The blue light emitted by smartphones and screens suppresses melatonin, the hormone that signals the body to rest, while gaming and streaming platforms keep the brain stimulated long past sunset. What was once an automatic biological rhythm has been quietly overridden by habit and choice. The problem deepened during the pandemic, when isolation and stress compounded existing sleep disturbances, and Sharma has since built programs in schools and communities across cities like Indore focused on sleep hygiene, digital habits, and mental wellbeing.
The consequences are measurable and serious. A single night of poor sleep reduces attention span by nearly 30 percent; months of chronic deprivation erode memory, concentration, and academic performance in ways that accumulate long before they become visible. Yet the crisis is difficult to confront precisely because it doesn't announce itself — the cost of a midnight scroll or an all-nighter arrives later, quietly, in the classroom or across the arc of a semester.
As awareness grows around World Sleep Day, experts are pressing a simple but urgent message: protecting sleep is not a wellness indulgence but a cognitive and developmental necessity. Establishing consistent schedules, stepping away from screens before bed, and understanding what those glowing devices are actually doing to the brain are becoming essential skills as urban life accelerates and digital temptation grows ever harder to resist.
On the eve of World Sleep Day, a troubling pattern has emerged across India's cities: the country now ranks second only to Japan in sleep deprivation, and the culprit is no mystery. Among young people—students and early-career professionals in urban centers—between 70 and 80 percent are sleeping less than the eight to ten hours their bodies need. Many are getting by on six or seven hours, often at irregular times that leave them foggy and unfocused the next day.
Archna Sharma, a sleep coach who has spent recent years raising awareness about rest and recovery, points to a straightforward explanation: the devices in our pockets have rewired how we sleep. Smartphones, late-night gaming sessions, and the endless scroll of streaming platforms keep the brain alert long past sunset. The blue light these screens emit suppresses melatonin—the hormone that tells your body it's time to wind down—which delays sleep onset and fragments what little rest does come. What used to be an automatic rhythm, the body's natural signal to rest, has been disrupted by choice and habit.
The problem intensified during the pandemic, when isolation and stress triggered widespread sleep disturbances. Sharma began her work in sleep awareness during those years, and has since conducted programs in schools and communities focused on sleep hygiene, digital habits, and mental wellbeing. The need for that work has only grown more urgent as cities like Indore and others across India continue to expand, bringing with them the pressures of competitive academics and the constant availability of digital stimulation.
The consequences are not abstract. Research shows that even a single night of inadequate sleep reduces attention span by nearly 30 percent. For students, this means concentration falters, memory weakens, and academic performance suffers. For young professionals, it means reduced productivity and increased error. The cumulative effect of months or years of chronic sleep loss compounds these deficits, affecting not just how well someone performs in school or at work, but how they feel, think, and function in daily life.
What makes this crisis particularly difficult to address is that it doesn't feel like a crisis in the moment. A teenager staying up until midnight scrolling through social media doesn't experience an immediate consequence—the cost comes later, in the classroom or on the exam. A college student pulling an all-nighter to finish an assignment doesn't see the damage until weeks of similar nights have accumulated. The body's need for sleep is treated as negotiable, something to sacrifice for productivity or entertainment, when in fact it is foundational to everything else that follows.
As awareness of World Sleep Day spreads, experts are increasingly vocal that young people need to understand what they are losing. The shift toward better sleep hygiene—putting phones away an hour before bed, establishing consistent sleep schedules, understanding how screens affect the brain—is not a luxury or a wellness trend. It is becoming essential as the pace of urban life accelerates and the pull of digital devices grows stronger.

A Conversa do Hearth Outra perspectiva sobre a história
Why does India rank second after Japan specifically? Is there something cultural about how these two countries approach work and rest?
The source doesn't explain the comparison, but you can infer it: both are rapidly urbanizing, highly competitive societies where academic and professional pressure is intense. Japan has been documenting this problem for longer. India is following a similar trajectory, especially in cities.
The 70-80% figure is striking. Does that mean most young people are sleep-deprived, or is there a subset we're talking about?
It's most young people in urban centers—students and young professionals. The source focuses on cities like Indore, not rural areas. So we're talking about the population with access to smartphones and OTT platforms, which is still tens of millions of people.
Blue light suppressing melatonin—that's well-known science. But why are young people in India particularly vulnerable to this?
The source doesn't claim they're uniquely vulnerable biologically. What's different is the context: academic pressure is high, screens are ubiquitous, and there's no cultural pushback against staying up late. Sleep isn't valued the way productivity is.
Sharma started this work during Covid. Has the problem gotten better or worse since then?
The source suggests it's gotten worse. The pandemic triggered the awareness, but the underlying drivers—screens, academic pressure, urban lifestyle—have only intensified since lockdowns ended.
A 30% reduction in attention span from one bad night—that's a huge number. Is that permanent?
No, it's acute. One night of poor sleep causes that dip. But if you're chronically sleep-deprived, the effects compound and become harder to reverse. That's the real danger for students sleeping six hours a night for months.
What would actually change this? Is it individual behavior or systemic?
The source doesn't prescribe solutions, but it implies both. Individuals need to change habits—put phones away, set schedules. But schools and workplaces would need to stop rewarding the culture of sleep deprivation that makes staying up late seem necessary.
