Why You're Not Sleeping Well (and What You Can Do About It)
“I never sleep right through the night”
“I’ve always been a restless sleeper”
"I dread 3am"
If any of these sound familiar, you're certainly not alone. In fact, I'd estimate around 80% of the people I see in clinic struggle with poor sleep, alongside digestive complaints, stress, fatigue or hormone imbalances. Because it's so common, many people assume restless nights are simply part of getting older or having a busy life.
They're not.
Sleep is one of the most powerful foundations of good health. When we consistently miss out on quality sleep, every system in our body suffers, from our brain and immune system to our hormones, metabolism and gut health.
The good news? There are many practical, evidence-informed ways to improve your sleep naturally. Let's explore why sleep matters so much and what you can do to wake feeling refreshed again.
Why Is sleep So Important For Your Health?
Most of us know we feel tired after a poor night's sleep, but the effects go far beyond simply feeling exhausted.
When both the quality and quantity of our sleep are reduced, our thinking slows. Our ability to focus, concentrate and make decisions suffers. Reaction times become slower, we become less productive, and we're more likely to make mistakes or take unnecessary risks.
Sleep also has a profound effect on our emotional wellbeing.
Research has shown that sleep deprivation increases our sensitivity to negative experiences and alters serotonin function in ways similar to those seen in depression. It's no wonder everything feels harder after several broken nights.
Sleep also plays a surprisingly important role in maintaining a healthy weight.
When we sleep well, our body increases production of leptin, the hormone that tells us we're full, while reducing ghrelin, the hormone responsible for stimulating appetite. If you've ever noticed you're hungrier after a poor night's sleep, there's a biological reason for it.
Poor sleep also increases inflammation throughout the body. Studies have shown insomnia can raise levels of C-reactive protein (CRP), an important marker of inflammation linked to cardiovascular disease and many chronic health conditions.
At the same time, inadequate sleep increases production of stress hormones like adrenaline and cortisol, making it even harder to relax and fall asleep the following night.
It quickly becomes a vicious cycle.
How Does Poor Sleep Affect Gut Health?
This is one of my favourite topics because so many people don't realise how closely sleep and digestion are connected.
Your digestive system follows its own daily rhythm, guided by your body's internal clock. While you're sleeping, your digestive tract repairs itself, your gut lining regenerates, your immune system gets to work and your gut microbiome carries out many of the tasks that keep you healthy.
Poor sleep disrupts all of these processes.
Research shows disrupted sleep can alter the balance of beneficial bacteria living in the gut, increasing inflammation and contributing to digestive problems such as bloating, IBS, constipation and altered bowel habits.
Sleep deprivation also affects appetite hormones, increasing cravings for highly processed foods that can further disrupt the gut microbiome.
If you're working hard to heal your gut but overlooking your sleep, you're making the journey much harder than it needs to be.
Why Do I wake At 3am?
This is one of the most common questions I hear in clinic.
While there's rarely one single cause, waking around 3am often points to an imbalance somewhere in the body's natural rhythms.
Common contributors include:
Elevated cortisol (our stress hormone)
Chronic stress and an overactive nervous system
Alcohol disrupting normal sleep cycles
Caffeine still circulating in the body
Blood sugar fluctuations overnight
Histamine sensitivity
Hormonal changes, particularly during perimenopause and menopause
Rather than trying to simply "knock yourself out" with supplements, it's worth understanding why your body is waking in the first place.
Once you identify the underlying cause, treatment becomes much more effective.
What Is The Circadian Rhythm?
You've probably heard of your circadian rhythm before.
It's your body's internal clock that regulates your sleep-wake cycle over a 24-hour period. Controlled by a tiny area in the brain called the hypothalamus, it governs the release of melatonin, our primary sleep hormone.
But circadian rhythm influences far more than just sleep.
It also regulates digestion, hormone production, metabolism, immune function and energy levels throughout the day.
Unfortunately, modern life constantly disrupts this natural rhythm.
Shift work, jet lag, irregular routines, bright lights, scrolling on our phones late into the evening and binge-watching television all confuse the brain's ability to produce melatonin when we need it most.
How Can I Improve My Circadian Rhythm Naturally?
The good news is your body loves routine. Small daily habits can make an enormous difference.
1. Keep a regular bedtime
Your brain thrives on consistency. Going to bed and waking up at roughly the same time each day helps train your body to produce melatonin at the right time.
2. Get outside in the morning
Morning sunlight is one of the strongest signals for setting your body clock. Even 10–20 minutes outdoors soon after waking can improve sleep that night.
3. Create a calming bedtime routine
Give your brain clear signals that sleep is approaching.
Think warm showers, dim lighting, calming music, essential oils, reading or gentle stretching.
4. Move your body
Regular exercise improves sleep quality, particularly when performed earlier in the day.
5. Be mindful of caffeine
Caffeine stimulates the nervous system and can remain active in the body for six hours or more.
Even your morning coffee may influence your sleep that evening if you're particularly sensitive.
6. Reduce light before bed
Dim the lights and minimise screen time during the hour before sleep.
Your brain interprets bright light as daytime and delays melatonin production.
7. Skip hot drinks before bed
Your body naturally lowers its core temperature to initiate sleep.
Hot drinks (even herbal tea) temporarily increase core temperature and may delay this natural process.
8. Eat enough protein
The sleep hormone melatonin begins with an amino acid called tryptophan, found in protein-rich foods including poultry, eggs, dairy, pumpkin seeds and almonds.
Pairing protein with healthy carbohydrates helps improve tryptophan absorption.
9. Consider histamines
Many people don't realise foods such as red wine, fermented foods and bone broth are naturally high in histamine.
Histamine promotes wakefulness, so reducing these foods in the evening can improve sleep for sensitive individuals.
Does caffeine really affect sleep?
Absolutely.
Caffeine is one of the most underestimated contributors to poor sleep.
Coffee, tea, green tea, matcha, chocolate, cacao, energy drinks and cola all contain caffeine.
While many people drink these to stay alert during the day, caffeine remains in the body far longer than most realise.
Research has shown even 200mg of caffeine consumed in the morning (roughly one to two double-shot coffees) can still affect sleep quality that night.
A few squares of dark chocolate after dinner may even be enough to prevent some people from falling asleep.
If you're struggling with insomnia, caffeine deserves careful attention.
Does alcohol help you sleep?
Although alcohol often makes us feel sleepy, it doesn't improve sleep quality.
In fact, it does the opposite.
Alcohol reduces the amount of restorative deep sleep and REM sleep we experience overnight.
While it may help you fall asleep initially, many people wake several hours later and struggle to return to sleep.
Alcohol is also thought to reduce melatonin production and increase snoring.
If you're relying on a nightly glass of wine to unwind, it may actually be contributing to your restless nights.
What foods help you sleep?
Sleep begins with good nutrition.
Melatonin is produced from the amino acid tryptophan, found in foods such as:
Eggs
Poultry
Cottage cheese
Pumpkin seeds
Almonds
Dairy foods
Legumes
Combining protein with a small amount of healthy carbohydrate helps improve absorption.
Eating enough protein throughout the day gives your body the building blocks needed to produce serotonin and ultimately melatonin.
What supplements can help you sleep naturally?
Sometimes good nutrition alone isn't enough, particularly during periods of chronic stress.
Here are some of the supplements I commonly consider in clinical practice.
1. 5-HTP
5-HTP is produced naturally from tryptophan and eventually converts into serotonin and then melatonin.
During periods of chronic stress, however, the body often diverts tryptophan down a different pathway, reducing the amount available for serotonin production.
For some people, supplementing with 5-HTP (alongside the right nutritional cofactors) can help restore this pathway.
2. Magnesium
Magnesium is one of the most commonly self-prescribed supplements for sleep.
It plays an essential role in serotonin production and helps muscles relax.
However, not all forms of magnesium are absorbed equally well.
Some forms mainly act as laxatives rather than supporting the nervous system, so choosing a quality product is important.
3. B Vitamins
B vitamins are critical for producing both serotonin and melatonin.
Without adequate B3 and B6, these neurotransmitters simply cannot be manufactured efficiently.
Because B vitamins work together, I generally recommend a quality B-complex rather than taking individual B vitamins.
4. Herbal Medicine
Herbal medicine offers a wide range of gentle but effective options for supporting sleep.
One of the greatest strengths of herbal medicine is that formulas can be tailored specifically to the individual rather than taking a one-size-fits-all approach.
Can stress stop you sleeping?
Without question.
When we're stressed, our nervous system switches into "fight or flight."
Our brain increases production of adrenaline and cortisol, keeping us alert when we should be winding down.
Unfortunately, this also suppresses digestion, alters the gut microbiome and makes it much harder to both fall asleep and stay asleep.
Learning to calm the nervous system is often one of the missing pieces in restoring healthy sleep.
If you'd like to understand this connection in more detail, have a read of my article Stress and Your Gut, where I explain how chronic stress affects both digestion and sleep.
When should you seek professional help?
If you've struggled with poor sleep for several weeks or months despite improving your routine, it's worth investigating further.
Persistent sleep problems may be linked with:
Chronic stress
Hormonal changes
Nutrient deficiencies
Digestive problems
Anxiety
Sleep apnoea
Blood sugar imbalance
Histamine intolerance
Rather than masking symptoms, it's important to identify what's driving your poor sleep.
Final thoughts
Better sleep isn't about finding one miracle supplement.
It's about helping your brain and body remember how to sleep naturally again.
Sometimes that means improving your circadian rhythm. Sometimes it's addressing stress, nutritional deficiencies or digestive health. More often than not, it's a combination of several small changes working together.
The encouraging news is that you don't have to accept poor sleep as "just the way you are."
