Sleep problems don’t just make you tired. They strip away your independence, one night at a time. As you get older, those restless nights you shrug off quietly erode your ability to function during the day. What starts as trouble falling asleep or waking too early snowballs into physical decline that’s hard to reverse.
Many people assume poor sleep is just part of aging, but that belief keeps them stuck. Insomnia is a warning sign that your body isn’t recovering the way it should. And when you turn to sleep medications to force rest, the consequences are even worse. If you’ve noticed your balance feels off, your energy is low or daily tasks are becoming harder, don’t overlook your sleep.
What you do — or don’t do — at night affects every system in your body. And if you’re relying on pills to get through it, you’re not fixing the problem. You’re feeding it. To understand just how serious this issue is, researchers tracked thousands of older adults over several years to see how insomnia and medication use affected their ability to live independently.
Sleep Drugs and Insomnia Both Raise Your Disability Risk
A study published in Sleep used data from 6,722 adults over the age of 65 as part of the National Health and Aging Trends Study.1 The researchers aimed to understand whether insomnia symptoms and the use of sleep medications would lead to greater disability over time.
The focus was on real-world outcomes like the ability to dress, bathe, eat and walk. The researchers accounted for health history, demographics and lifestyle risks to measure how disability scores changed year to year in relation to sleep problems.
• The research focused on a vulnerable population already at risk for declining mobility — Participants were all Medicare beneficiaries, living independently in the community, not in nursing homes or assisted care. Their health status varied, but they were mostly representative of the general aging population in the U.S.
Disability was assessed using a system where each task, like showering or getting out of bed, was scored. If someone had difficulty or needed help, that raised their disability score. A rise of just two points was considered a meaningful sign of functional decline.
• Even mild increases in sleep troubles predicted more physical disability the following year — For every step up in reported insomnia symptoms, such as from never to once a week, a person’s disability score increased by 0.2 points the following year.
That may sound small, but the progression added up quickly. Someone who shifted from never having insomnia to struggling every night faced a full-point increase each year — enough to push them toward needing assistance with basic daily activities.
• Using sleep medications made things worse, and it didn’t take much — The same scoring method was used to track sleep medication frequency. Participants who increased their use from rarely to regularly experienced a 0.19-point rise in disability scores each year. Not only did sleep medications fail to stop the decline tied to insomnia — they worsened it.
• Those who used sleep drugs and had insomnia suffered the most rapid decline — According to study co-author Orfeu Buxton of Pennsylvania State University, this combination — ongoing insomnia plus regular use of sleep drugs — created a feedback loop of worsening function.
Participants in this group experienced the steepest increase in disability scores over time. “… As older people used more sleep medication or experienced more insomnia symptoms, they moved more rapidly towards greater disability,” he said in a news release.2
• The rise in disability was consistent, predictable and clinically meaningful — A consistent year-over-year rise in disability scores, especially among those with chronic sleep issues, reflected a loss of independence. Daily activities that once seemed simple, like getting dressed or walking outside, became harder, and eventually required help.
Many Older Adults Believe Sleep Problems Are ‘Normal’
Soomi Lee, a co-author of the study, emphasized that insomnia should not be brushed off as a harmless part of aging, as many older adults believe. “Insomnia can decrease a person’s quality of life both directly and indirectly,” she said.3 The longer it goes unmanaged, or masked with medication, the more likely it is to rob you of your independence.
• Sleep medication likely increases fall risk, which accelerates disability — While the study didn’t measure falls directly, previous research showed that older adults on sleep medications are more likely to fall.4 This is one likely reason why their disability worsened more quickly. The sedative effects of these drugs often linger into the morning, impair balance and dull reflexes. That makes nighttime drugs a direct threat to daytime mobility.
• Doctors need to address insomnia with safer, more effective treatments than pills — According to the research team, physicians should be screening older patients for sleep issues and reviewing medication lists carefully. Sometimes insomnia is caused by drug interactions, poor light exposure or stress.
Cognitive behavioral therapy for insomnia, which helps people reframe thoughts and habits that interfere with sleep, is a safe and proven alternative to medication that doesn’t raise disability risk.
Sleep in Total Darkness and Fix Your Nighttime Environment
If you’re struggling with sleep, especially if you’re older, this isn’t just about feeling tired — it’s about protecting your independence. What you do at night affects how you function during the day. The more nights you lose sleep or rely on medication to force it, the faster your risk for disability rises. But you’re not stuck.
There are safer, more effective ways to reset your sleep without sedatives, and it starts with removing the factors that block your body’s natural rhythm. Here’s what to do if you want to fall asleep more easily, sleep more deeply and avoid the long-term consequences that come with insomnia and drug use:
1. Sleep in complete darkness every night — Your body relies on light cues to know when it’s time to rest. Even a small amount of light in your bedroom, like a streetlight through the window or the glow from a digital clock, disrupts melatonin production.
Melatonin is your brain’s natural signal that it’s time to shut down. If you regularly wake up at 2 a.m. and struggle to fall back asleep, your room is probably too bright. Use blackout curtains, remove glowing electronics and eliminate any nightlights that aren’t absolutely necessary.
2. Remove all electromagnetic field (EMF) sources from your bedroom — If you sleep with your phone next to your head or have Wi-Fi signals pulsing through your bedroom, you’re interfering with your nervous system’s ability to rest. EMFs cause mitochondrial damage, DNA fragmentation and neurological issues, and disrupt sleep architecture.
Remove your cellphone from your bedroom, unplug your router at night and move anything wireless out of your sleeping space. You’ll notice the difference within days.
3. Avoid blue light after sunset — Blue light from screens tells your brain it’s still daytime, even when it’s pitch black outside. This is one of the biggest disruptors of deep, restorative sleep. If you’re using your phone, computer or watching TV at night, you’re sending the wrong message to your brain.
Wear blue light-blocking glasses after sunset, or better yet, shut off screens when the sun goes down. Replace that time with reading, stretching or a warm shower to help your body shift into rest mode.
4. Move your body during the day to sleep better at night — Your sleep at night is shaped by your activity during the day. If you’re sedentary or spend hours sitting, your body doesn’t build enough internal pressure to feel truly tired when bedtime comes.
Regular daily movement, especially walking and strength training, helps regulate your circadian rhythm, reduces stress hormones and improves blood sugar control, all of which directly support better sleep. If you struggle to fall asleep or wake up feeling tired, a 60-minute walk during daylight hours will make a major difference.
5. Use sleep as a feedback tool for deeper issues — If your sleep is off, something else in your system is likely off too — blood sugar, stress, circadian rhythm or even gut health. Instead of masking the symptom with medication, use it as a signal.
Are you getting enough sunlight during the day? Are you eating enough healthy carbohydrates to support cellular energy production? Fix those upstream issues and sleep improves as a result. The research is clear: sleep drugs don’t fix the root issue; they just numb your awareness of it.

FAQs About Insomnia, Sleep Drugs and Disability
Q: How does insomnia affect older adults’ long-term health?
A: Insomnia significantly raises the risk of disability in older adults. According to recent research, each increase in insomnia symptoms, like difficulty falling or staying asleep, correlates with a measurable decline in a person’s ability to perform basic tasks like dressing, bathing and walking. Over time, this sleep disruption accelerates loss of independence.
Q: Are sleep medications a safe solution for insomnia?
A: No. The study found that regular use of sleep medications increases disability risk just as much as insomnia itself. When used frequently, these drugs contribute to faster physical decline, likely due to side effects like impaired coordination and increased fall risk. Using both sleep meds and experiencing insomnia is associated with the worst outcomes.
Q: What is the most important first step for improving sleep naturally?
A: Sleep in total darkness. Your brain needs complete darkness at night to produce melatonin, the hormone that signals rest. Even small amounts of light from electronics or streetlights suppress melatonin and interfere with deep, restorative sleep.
Q: Why should I eliminate EMFs from my bedroom?
A: EMFs from devices like cellphones, Wi-Fi routers and Bluetooth signals disrupt your nervous system and interfere with natural sleep cycles. Removing these signals at night — by unplugging or turning devices off — helps calm your system and supports better-quality rest.
Q: What are safer, nondrug options for treating insomnia?
A: Instead of relying on medications, focus on behavioral and lifestyle strategies. These include avoiding blue light after sunset, following a regular sleep-wake schedule and getting regular daily movement, like walking and strength training. These changes support your body’s natural ability to rest and recover.
