June is Men’s Health Month, a time dedicated to raising awareness of the health challenges that affect men throughout their lives.
When people think about ageing, they often expect a few changes: perhaps slightly slower recovery from exercise, a few more aches and pains, or needing reading glasses. What many men don’t anticipate is how dramatically their sleep can change.
For many men, insomnia isn’t about struggling to fall asleep - it’s about staying asleep. Studies show that nighttime urination is among the most commonly reported causes of disturbed sleep in older adults (1). At the same time, insomnia becomes increasingly common with age, with nearly half of older adults reporting symptoms of insomnia (2).
The scenario is familiar to many men.
You fall asleep without difficulty, only to find yourself wide awake at 3am. Sometimes it's a trip to the bathroom. Sometimes your mind suddenly starts racing. Other times, there seems to be no obvious reason at all. You check the clock, try to get comfortable, and then spend the next hour staring at the ceiling, wondering why your sleep has suddenly abandoned you.
While this experience is often associated with "older men", many begin noticing changes much earlier than expected. For some, disrupted sleep starts appearing in their late 30s or 40s and gradually becomes more frequent over time. Many of the changes behind sleep disruption are linked to biology, hormones, metabolism, stress, and lifestyle factors that can often be improved with the right support.
In my practice, I often speak with older men who are frustrated by waking in the night and struggling to get back to sleep.
In this article, we'll explore how sleep changes with age in men, the most common causes of those frustrating 3am wakeups, and practical strategies to naturally improve sleep quality, including the growing interest in CBD for sleep.
How sleep changes with age in men
One of the biggest misconceptions about ageing and sleep is the belief that older adults simply need less sleep. Research suggests that sleep requirements remain relatively similar throughout adulthood. What changes is often the quality of sleep rather than the quantity. This distinction is important when discussing age and hours of sleep.
Many men still spend seven to eight hours in bed but wake feeling far less refreshed than they did in their twenties.
Several biological changes contribute to this:
Reduced deep sleep
As men age, they naturally spend less time in slow-wave sleep, often referred to as deep sleep. This stage is responsible for physical recovery, tissue repair, immune function, and feeling refreshed the next day.
More fragmented sleep
Sleep cycles become lighter and more easily disrupted. External noise, stress, temperature changes, and physical discomfort can trigger awakenings more easily than they once did.
Earlier wake times
The body's internal clock, known as the circadian rhythm, tends to shift with age. Many men find themselves becoming sleepy earlier in the evening and waking earlier in the morning.
These changes help explain why conversations around age and hours of sleep are often more complex than simply sleeping fewer hours.
Why insomnia becomes more common in older men
When discussing insomnia and old age, many people think of difficulty falling asleep. However, one of the most common forms of insomnia in men over 40 is known as sleep maintenance insomnia. This refers to waking during the night and struggling to fall back asleep.
The causes are rarely isolated to a single factor. Instead, sleep disruption often develops through a combination of:
- Hormonal changes
- Blood sugar fluctuations
- Increased stress
- Medical conditions
- Lifestyle habits
- Natural changes in sleep architecture
Understanding these root causes is the first step toward finding effective solutions.
7 reasons men wake up at 3am (and why it starts earlier than you think)
1. Melatonin decline
Melatonin is the hormone that helps regulate the body's sleep-wake cycle. Production naturally declines with age, making it harder to maintain deep, restorative sleep throughout the night.
Modern lifestyles can worsen the problem. Evening exposure to bright lighting, televisions, smartphones, and tablets can further suppress melatonin production and disrupt circadian rhythms.
The result can be lighter sleep and more frequent waking during the early hours.
2. Blood sugar imbalances
Blood sugar regulation plays a much larger role in sleep than many people realise. If blood glucose levels drop too low during the night, the body may release stress hormones such as cortisol and adrenaline to restore balance.
Unfortunately, these hormones can also wake you up.
Men with insulin resistance, metabolic syndrome, pre-diabetes, or poor blood sugar control may be particularly vulnerable to these overnight disruptions.
3. Testosterone decline
Testosterone levels naturally decrease with age. Research suggests lower testosterone levels may be associated with poorer sleep efficiency, reduced sleep duration, and increased night waking.
Because sleep also supports testosterone production, a frustrating cycle can develop in which poor sleep lowers testosterone, which then further impacts sleep quality.
4. Stress and cortisol
Stress remains one of the most overlooked causes of disrupted sleep. Career pressures, financial responsibilities, family concerns, retirement planning, health worries, and general life stress can all contribute to elevated cortisol levels.
Cortisol naturally rises in the early morning to help us wake up. However, chronic stress may cause this rise to occur too early or too intensely.
For many men, the result is a sudden 3am awakening accompanied by a racing mind.
5. Age-related sleep fragmentation
As previously discussed, ageing naturally shifts sleep toward lighter stages. This means men are more likely to wake briefly throughout the night.
In younger adults these awakenings often go unnoticed. As sleep becomes lighter, however, these interruptions become more noticeable and more difficult to recover from.
This contributes significantly to the relationship between insomnia and old age.
6. Prostate health and nocturia
One of the most common reasons men wake during the night is nocturia - the need to urinate multiple times overnight.
Benign Prostatic Hyperplasia (BPH), commonly known as an enlarged prostate, becomes increasingly common with age. Even mild enlargement can place pressure on the bladder and increase urinary frequency. For many men, the initial wake-up is due to the bladder. The bigger challenge is often getting back to sleep afterwards.
7. Alcohol and sleep disruption
Alcohol is often mistaken for a sleep aid.
While it may help induce sleep initially, it tends to reduce sleep quality later in the night.
Alcohol can:
- Reduce REM sleep
- Increase night waking
- Promote dehydration
- Increase trips to the bathroom
- Exacerbate snoring and sleep apnoea
Many men notice significant improvements in sleep quality simply by reducing evening alcohol consumption.
Why waking at 3am matters for long-term health
Occasional sleep disruption is normal. Chronic sleep interruption, however, can affect multiple aspects of health, including:
Weight gain and insulin resistance
Poor sleep can influence appetite-regulating hormones, increase cravings, and worsen insulin sensitivity.
Mood and anxiety
Persistent sleep disruption is strongly associated with increased stress, anxiety, irritability, and reduced emotional resilience.
Cognitive function
Sleep plays a critical role in memory consolidation and brain health. Ongoing sleep deprivation has been linked with cognitive decline and reduced mental performance.
Testosterone production
Much of testosterone production occurs during sleep. Repeated interruptions may further impact hormone balance and recovery.
How to improve sleep naturally as you get older
Fortunately, many causes of disrupted sleep can be addressed through practical lifestyle changes.
1. Stabilise blood sugar at night
Consider including protein and healthy fats with your evening meal.
Examples include:
- Greek yoghurt
- Nuts and seeds
- Eggs
- Oily fish
Try to minimise late-night sugary snacks and excessive alcohol consumption.
2. Support your circadian rhythm
Morning sunlight exposure helps reinforce healthy sleep-wake cycles. Aim to spend time outdoors shortly after waking. In the evening, reduce exposure to bright screens and artificial lighting where possible.
3. Manage stress and cortisol
Creating a consistent wind-down routine can help prepare the nervous system for sleep.
Helpful strategies may include:
- Breathing exercises
- Meditation
- Reading
- Gentle stretching
- Magnesium supplementation where appropriate
4. Support prostate health
Simple changes can sometimes reduce overnight bathroom visits.
These may include:
- Reducing fluid intake close to bedtime
- Maintaining a healthy weight
- Following an anti-inflammatory diet
- Seeking medical assessment for urinary symptoms
CBD for sleep: can it help you stay asleep?
Interest in CBD for sleep has grown considerably in recent years.
Unlike products that directly sedate the body, CBD appears to interact with the endocannabinoid system - a network involved in regulating stress responses, mood, inflammation, and sleep-wake balance.
Emerging research suggests CBD may support sleep by helping to reduce hyperarousal, the state of mental and physical alertness that often contributes to insomnia.
This may be particularly relevant for:
- Men experiencing 3am wakeups
- Stress-related sleep disruption
- Light sleepers
- Individuals struggling to switch off mentally
One widely cited clinical case series found that 67% of participants experienced improved sleep scores within the first month of CBD use (3).
While CBD for sleep is not a cure for insomnia and should not replace appropriate medical care, many individuals report improvements in relaxation, sleep quality, and the ability to return to sleep after waking at night.
How to use CBD for better sleep
If you're considering CBD for sleep, consistency is often more important than taking large amounts.
Timing
Many people choose to take CBD approximately 30–60 minutes before bedtime.
Format
CBD oils may offer greater flexibility and faster absorption, while capsules can provide convenience and consistent dosing.
Consistency
Like many wellness strategies, benefits may become more noticeable when used regularly over several weeks.
Pair CBD with good sleep habits
CBD is most effective when used alongside healthy sleep behaviours, including:
- Managing stress
- Reducing alcohol intake
- Supporting blood sugar balance
- Following a consistent bedtime routine
When incorporated into a broader wellness strategy, CBD for sleep may offer valuable support for men seeking more restorative rest.
Final thoughts: sleep doesn't have to get worse with age
Sleep changes from your 40s onward are common, but they are not necessarily something you have to simply accept.
Many of the factors driving 3am wake-ups - including hormone changes, stress, blood sugar fluctuations, prostate health, alcohol intake, and disrupted circadian rhythms - can often be improved through targeted lifestyle strategies.
Understanding the relationship between age and hours of sleep helps shift the conversation away from simply sleeping less and toward improving sleep quality.
Likewise, recognising the connection between insomnia and old age allows men to address underlying causes rather than viewing poor sleep as inevitable.
Alongside healthy lifestyle habits, CBD for sleep may offer additional support for individuals looking to improve relaxation, reduce stress-related sleep disruption, and encourage more restorative sleep patterns.
If you're waking at 3am more often, you don't have to accept it as just part of getting older. With the right combination of lifestyle changes and supportive tools like CBD, you can work toward more rested, consistent sleep at any age.
