Your grandparents sleep better than you do. Not longer, necessarily, but better when it comes to actually falling asleep. According to CDC data analyzed by health research platforms, 15.5% of adults aged 18 to 44 report trouble falling asleep, compared to just 12.1% of adults 65 and older. This inverts everything we think we know about aging and insomnia.
The conventional wisdom is simple: getting older breaks your sleep. Your circadian rhythms drift. Your body produces less melatonin. You wake up at 4 a.m. thinking about your heating bill. We've been sold the idea that insomnia is a senior citizen problem, the cost of admission to old age. Pharmaceutical companies built an empire on this assumption, marketing sleep aids as inevitable furniture for the aging. Yet the numbers don't support it. Young people are actually worse at the fundamental task of closing their eyes and drifting off.
The actual pattern is more nuanced. Older adults do struggle with sleep, but their problem is different. They fall asleep fine. They just can't stay asleep. They wake up multiple times per night, and these fragmented sleep episodes feel worse than a solid six hours would. It's a maintenance problem, not an access problem. Meanwhile, younger adults face what researchers call "sleep onset latency"—they lie awake staring at the ceiling for an hour, mind racing, unable to initiate sleep despite genuine fatigue. These are two distinct insomnia flavors, and they have different causes.
The culprits are familiar if you live in 2024: stress, technology, and schedules that would have baffled your ancestors. Younger adults navigate volatile job markets, social media streams, financial precarity, and—for many—pandemic-era habit disruption that never really resolved. Our brains stay cognitively active later into the evening. We check our phones before bed, flooding our visual cortex with blue light that suppresses melatonin production. We work from home, which erases the boundary between workspace and bedroom, training our nervous systems to stay alert in the room where we're supposed to rest. A 2024 ScienceDaily analysis of sleep research highlighted how these modern stressors specifically damage sleep onset mechanisms in younger populations, while older adults, having largely exited the workforce and social media arms race, face different challenges tied to aging biology itself.
Older adults, meanwhile, have solved the fall-asleep problem through years of practice and lower ambient cortisol. What they've lost is sleep architecture—the ability to stay in a consolidated sleep bout. Their bodies wake more easily, partly due to changes in the proteins that regulate sleep-wake cycles, partly due to medication side effects, partly due to needing to urinate. But they're not lying awake at 11 p.m. spiraling about Slack messages.
The implication is worth sitting with: our sleep crisis isn't primarily biological. It's environmental and psychological. You can't medicate your way out of a schedule that doesn't fit human neurology, or a device that's engineered to keep you engaged. Your 70-year-old relative has an advantage not because their body is superior, but because their life is structurally less designed to keep them wired. That's both a diagnosis and, possibly, a hint at a solution.
