22 Reasons Why It’s So Hard to Sleep as You Get Older

Monica Gray - June 8, 2025

As we age, our sleep patterns naturally evolve, making restful nights more elusive for many adults. Difficulty falling or staying asleep is a widespread concern, influenced by a complex blend of physical, mental, and environmental factors.
While some changes are simply a normal part of growing older, others stem from health conditions or lifestyle shifts. Understanding these challenges is the first step toward better sleep. In this article, we’ll explore the 22 most common reasons why sleep becomes harder with age—and what you can do about it.

1. Changes in Circadian Rhythm

As we grow older, our body’s internal clock—known as the circadian rhythm—begins to shift. Many older adults experience advanced sleep phase syndrome, feeling sleepy much earlier in the evening and waking up earlier in the morning. This disruption can make it challenging to get a full night’s rest.
For a deeper look into this phenomenon, visit the Sleep Foundation.

2. Reduced Melatonin Production

As we age, our bodies produce less melatonin, the hormone that signals when it’s time to sleep. This decrease makes it harder to both fall asleep and stay asleep through the night.
Some people turn to melatonin supplements, but it’s important to consult a healthcare professional first. Learn more from Mayo Clinic.

3. Increased Prevalence of Sleep Disorders

As we get older, the risk of developing sleep disorders rises significantly. Conditions such as insomnia, sleep apnea, and restless legs syndrome are particularly common among older adults.
These disorders can fragment sleep, leaving you feeling tired during the day and affecting overall well-being. Many require medical evaluation and treatment to manage symptoms. For more information, visit the National Institute on Aging.

4. Chronic Pain

Chronic pain is a common companion to aging, often stemming from conditions like arthritis, back pain, or neuropathy. Persistent discomfort can make it hard to find a restful position, resulting in repeated awakenings and less restorative sleep.
Because pain and sleep are so closely linked, poor sleep can further intensify pain, creating a frustrating cycle. Explore more at Johns Hopkins Medicine.

5. Frequent Nighttime Urination (Nocturia)

Nocturia, or waking up to use the bathroom during the night, becomes more common with age. This issue often results from prostate enlargement in men or hormonal shifts in women.
These frequent interruptions can fragment sleep and make it hard to feel rested. Addressing underlying causes and adjusting evening fluid intake may help. Learn more at Cleveland Clinic.

6. Medication Side Effects

As we age, it’s common to rely on medications for conditions like high blood pressure, depression, or heart disease. Unfortunately, many medications can interfere with sleep, causing insomnia or frequent nighttime awakenings.
It’s important to regularly review all medications with your healthcare provider, as adjustments may improve sleep quality. For more information, see the CDC.

8. Sleep Environment Changes

With age, many people become more sensitive to environmental disturbances like noise, light, or uncomfortable room temperatures. Even small changes in the bedroom can disrupt sleep or make it difficult to fall back asleep after waking.
While adjusting your sleep environment can help, older adults often remain more vulnerable to these disruptions. Discover tips at the Sleep Foundation.

9. Increased Stress and Anxiety

Stress and anxiety often grow with age, fueled by health issues, financial concerns, or the loss of loved ones. These worries can linger at bedtime, making it hard to relax and fall asleep.
Persistent stress can turn into a cycle of sleeplessness and further anxiety. Practical strategies for managing these feelings are available at the American Psychological Association.

10. Depression

Depression is closely connected to sleep problems in older adults, including both insomnia and excessive sleepiness (hypersomnia). Often, sleep disturbances can be an early warning sign of depression.
Addressing depression with proper treatment can improve both mood and sleep quality. Learn more from NIMH.

11. Medical Conditions

Chronic illnesses such as diabetes, heart disease, and Parkinson’s disease often interfere with restful sleep. Symptoms like pain, breathing issues, or frequent urination can keep you awake or cause nighttime awakenings.
Effectively managing these medical conditions is essential for improving sleep quality. Find more information at NIH.

12. Breathing Problems

Breathing difficulties, such as asthma, chronic obstructive pulmonary disease (COPD), and sleep apnea, become more frequent as we age. These respiratory issues can cause repeated nighttime awakenings, making restorative sleep harder to achieve.
Accurate diagnosis and ongoing treatment are essential to improve both breathing and sleep quality. Learn more at the American Lung Association.

13. Changes in Sleep Architecture

As we age, our sleep architecture changes, with less time spent in deep, restorative sleep and more in lighter stages. This shift leads to more fragmented, less refreshing rest.
The result is that older adults often wake up feeling less restored, even after a full night in bed. Explore more at Healthline.

14. Increased Sensitivity to Noise

With age, changes in hearing and the way the brain processes sound can make environmental noise more disruptive. Even minor sounds may cause frequent awakenings or lighter sleep.
Using earplugs or a white noise machine can be helpful for minimizing disturbances. More tips from the Sleep Foundation.

15. Temperature Regulation Issues

As the body ages, its ability to regulate internal temperature declines, making people more sensitive to both cold and heat during the night. Even small temperature shifts can cause discomfort and disrupt sleep, especially during seasonal transitions.
Adjusting bedding and room temperature can help. Find practical tips at Harvard Health.

16. Napping During the Day

Frequent or extended daytime naps can make it more difficult to fall asleep at night. Many older adults nap to make up for lost sleep, but this can create a cycle of nighttime wakefulness and daytime drowsiness.
Moderation and timing of naps are key. See more advice from Sleep Foundation.

17. Reduced Exposure to Natural Light

Limited time outdoors means less exposure to natural sunlight, which helps regulate our internal sleep-wake cycle. For older adults, this can disrupt circadian rhythms and make insomnia worse.
Making an effort to spend time outside each day—even for a short walk—can improve sleep quality. Learn more at CDC.

18. Changes in Diet and Digestion

Digestive changes are common with age, and eating late or consuming heavy meals can trigger heartburn or indigestion. These discomforts often disrupt the ability to fall or stay asleep.
Adjusting meal timing and food choices can help. Find nutrition tips at NIH.

19. Alcohol and Caffeine Sensitivity

With age, sensitivity to alcohol and caffeine increases, making their effects on sleep more pronounced. Even a small cup of coffee or a single evening drink can interfere with falling or staying asleep.
Being mindful of consumption—especially later in the day—can help promote better rest. More details at Sleep Foundation.

22. Decreased Sleep Drive

As we age, the natural sleep drive—also known as sleep homeostasis—tends to weaken. This means the internal “pressure” to sleep doesn’t build as strongly, making it more challenging to fall asleep and remain asleep throughout the night.
Understanding this change can help set realistic expectations for sleep. Further reading at Sleep Foundation.
