What is Sleep?

Sleep is a complex process that researchers are still puzzling over. Many questions about what happens during sleep remain unanswered.
We know that multiple parts of the brain work in tandem to send signals to the body that it is ready for sleep.
These signals include melatonin: a hormone your body releases in a dark environment. Melatonin makes you feel sleepy and ready to rest. You may have seen the many melatonin products available as sleep aids at your local pharmacy.
Adenosine is another signal. This chemical builds up in your brain while awake. You need sleep to break it down as part of the body’s natural cycle of energy metabolism.
If you say you’re ready to get a ‘good night’s sleep’, it means you’re attuned to these natural signals. Falling asleep when your body calls you to do so is advisable, so don’t fight or force this urge to sleep.
Typically, you should then sleep for seven to nine hours. In the process, you’ll hopefully get enough of each type of sleep.
There are two main types:
- Rapid eye movement (REM)
- Non-REM
These sleep types are linked to patterns of electrical activity in your brain that fluctuate throughout the night. You typically experience 3-5 cycles between REM and non-REM as you sleep.
We often use the term ‘deep sleep’ for non-REM since it’s when your brain wave activity slows down the most. On the other hand, your brain wave activity during REM is quite close to when you’re awake. This is why dreaming typically occurs during REM sleep.
Scientists still debate the why behind our dreams. They tend to believe that dreams help us process emotions in some way. Researchers also generally agree that both sleep types help us store memories.
Why Does Sleep Matter?

Sleep for seniors is about so much more than just setting you up for the day to come. It plays a pivotal role (still not fully understood) in maintaining your long-term brain and heart health. Getting enough sleep can even upgrade your immune system.
When we sleep, our body gets to work. It repairs various cells, consolidates memories, and regulates the key hormones that help us function. Think of it like a nightly natural reset, just like putting your car into the shop for a regular tune-up.
When we don’t get enough sleep, we suffer. We don’t give our body the time it needs to perform that much-needed maintenance.
As a result, we feel irritable. We have trouble concentrating. This can add more stress to our relationships and affect our ability to complete daily tasks. Being tired also risks our chances of falls and accidents.
These are the noticeable consequences of a lack of sleep.
But, to continue the metaphor, there are potentially more disturbing things going on under the hood: a lack of good, quality sleep increases our risk of conditions like heart disease, diabetes, and cognitive decline.
The takeaway is that we owe it to ourselves to guard against this, to try to give our body and mind the restorative sleep they crave.
The bad news is that as we get older, just when we need to be most mindful of our health, we also find it much more difficult to get this rejuvenating rest.
How Aging Affects Sleep
Our sleeping patterns naturally shift as we age.
Do you remember your teenage years? Feeling like you could stay up late and sleep in until noon if you wanted to?
When your typical teenager enjoys a long sleep in, they aren’t simply lazy – it’s just that their natural bodily rhythms play to a different tune than a 60+ senior.
As you get older, you may find yourself heading to bed earlier. Perhaps you’re waking earlier in the morning, too, or experiencing intermittent sleep as you wake more frequently throughout the night.
Many of these changes are normal among older people. They are nothing to worry about as changing hormone balances dictate your circadian rhythms.
Yet more chronic sleep problems can take a toll on your health.
Common challenges that can interfere with sleep in older adults include:
- Lighter sleep: You may not experience as much deep sleep, making it easier to wake up during the night.
- Increased nighttime awakenings: This can be due to pain, medication side effects, or frequent trips to the bathroom.
- Sleep disorders: Insomnia, sleep apnea, and restless legs syndrome are more common in older adults.
- Health conditions: Chronic pain, arthritis, or heartburn can make it difficult to sleep comfortably.
The Importance of Sleep for Brain Function

A good night’s sleep is especially important for brain health.
Some research suggests that sleep at night helps clear toxins from the brain that contribute to cognitive decline and dementia, though recent studies cast doubt on whether sleep ‘cleans’ the brain in this way.
Yet, what remains clear is that sleep disturbances, such as fragmented sleep or sleep apnea, do lead to a higher risk of developing Alzheimer’s disease.
Further studies have shown that both too little and too much sleep can negatively impact cognitive function in older adults. Sleep deprivation has been associated with declines in various cognitive abilities, including:
- Memory: Difficulty retaining new information and recalling past events.
- Attention: Struggles with focus and concentration.
- Processing speed: Slower reaction times and reduced ability to quickly interpret information.
- Reasoning and problem-solving: Challenges in logical thinking and decision-making.
- Executive functioning: Reduced ability to plan, organize, and manage tasks effectively.
Older adults may experience a greater decline in these cognitive abilities after sleep loss than younger individuals. That’s what makes getting a ‘good night’s sleep’ all the more important as we age.
If you or a loved one are having trouble sleeping, it’s worth discussing with a doctor. Together, you can explore solutions that could improve both sleep quality and long-term brain health.
As a quick summary, we know that not getting enough sleep can harm your body in various ways:
- Increasing your risk of high blood pressure, heart disease, and diabetes
- Problems with memory
- More stress in relationships
- Increased risk of falls and accidents
On top of everything else, let’s not forget that being tired is an unpleasant experience, too. We want to feel well-rested to approach each day with a positive mindset.
Luckily, there’s plenty of advice on hand to help you improve your sleep hygiene.
Simple Ways to Sleep Better
You’ll probably have to go through a trial-and-error phase as you search for a solution to get that all-important shuteye. Try a mixture of the following simple tips:
Follow a regular schedule
We already mentioned our bodies tend to follow a circadian rhythm. We all have a natural ebb and flow of energy levels that hint at when we should wake up and go to bed.
Help your body out by listening to these rhythms. Go to bed and get up at roughly the same time each day, even on the weekend or when traveling.
Have a bedtime routine

Routines are your friend when it comes to sleep. Find ways you can rely on to help you unwind before bedtime each night.
Stick to what works. This could be a warm bath or listening to soothing music. It could be reading a book. Sleep meditation apps like Calm are increasingly popular to help you wind down.
There’s no one-size-fits-all solution; find what appeals and works for you.
Make the room comfortable
Do you like soft or hard pillows? A thick duvet or a thin sheet? This may change with the seasons. You don’t want to be too hot or too cold. You need to offer your back and neck the support they need as well.
This tip is all about setting the right foundations in your immediate environment to help you sleep. A good mattress that’s right for you can be a worthwhile investment.
Get regular exercise

Daily exercise is vital for so many reasons as we get older. Its relevance here is to burn off energy that makes sleeping that little bit easier. However, don’t exercise too close to bedtime; the release of endorphins associated with physical activity can disrupt your sleep.
Avoid afternoon naps
It’s best to fend off that tempting afternoon slump. An afternoon siesta may reduce your chances of having a good night’s sleep later when it matters all the more.
Watch what you eat and drink
Consuming too much caffeine later in the day can keep you awake at night. You’ll want to avoid caffeine-heavy beverages and foods like coffee, tea, chocolate, and soda.
Heavy meals too close to bedtime can also be an issue, while drinking alcohol plays havoc with your sleep cycles, too.
Minimize your screen time before bed

Screen time disrupts your ability to wind down and relax your mind. Specifically, the blue light that is emitted from our various screens prevents that all-important natural melatonin release, thus harming our ability to fall asleep.
For this reason, it’s best practice to impose a curfew on screen time for at least half an hour before bed (this is a great opportunity to kickstart your screen-free bedtime routine).
Better sleep is possible at any age. By making some of these small, thoughtful adjustments to your routine and environment, you can enjoy deeper, more restorative rest—and wake up ready to embrace each day with energy and clarity.
Sleep for Older Adults: When to Seek Help
If you’ve tried improving your sleep habits but still struggle with falling or staying asleep, it may be time to talk to a doctor.
Persistent sleep issues can be a sign of underlying medical conditions, and there are many treatment options available.
Here are some signs that indicate you should seek medical advice:
- Frequent difficulty falling or staying asleep despite following good sleep hygiene practices.
- Feeling excessively tired during the day, even after a full night’s sleep.
- Loud snoring or gasping for air during sleep, which may indicate sleep apnea.
- Trouble with memory, focus, or mood changes that could be linked to poor sleep.
A doctor may recommend stricter lifestyle changes. They may suggest cognitive behavioral therapy for insomnia (CBT-I), or medical interventions such as CPAP therapy for sleep apnea.
You might consider sleep medications, but these should be a last resort. Use sleep medication under careful supervision and watch out for troubling side effects.
