Introduction:

If you’re tossing and turning at night, staring at the ceiling, or waking up exhausted no matter how early you go to bed, you’re not alone. Millions of people struggle with insomnia or poor-quality sleep, yet most don’t realize that the issue goes far beyond just “stress” or “bad sleep habits.”

Sleep is one of the most vital processes for healing, hormone balance, cognitive function, and emotional regulation. When it breaks down, the consequences ripple throughout every aspect of your health. At Sheen Vein & Cosmetics, we use a functional medicine approach to identify and address the root causes of sleep disturbances, not just mask the symptoms with sleep aids.

In this article, we’ll explore 7 surprising reasons you might not be sleeping—and what you can do about them.

1. Blood Sugar Imbalances

Many people think of blood sugar only in terms of diabetes, but even subtle imbalances can wreak havoc on your sleep. When your blood sugar drops too low at night (hypoglycemia), it activates your adrenal glands to release cortisol and adrenaline—stress hormones that can cause you to wake up suddenly or prevent deep sleep.

Signs this may be your issue:

• You wake up between 2–4 a.m.
• You feel shaky, sweaty, or anxious at night
• You get “hangry” or irritable if meals are delayed

Functional Solution:
Stabilize blood sugar by including healthy fats, fiber, and protein with every meal. Avoid high-sugar snacks before bed, and consider a small protein-rich snack in the evening like almond butter on a rice cake or turkey slices.

2. Cortisol and Adrenal Dysfunction

Your body follows a natural circadian rhythm, with cortisol levels highest in the morning and lowest at night. But chronic stress, inflammation, and poor lifestyle habits can cause cortisol to spike at night, making it hard to fall asleep or stay asleep.

Signs this may be your issue:

• Racing thoughts at bedtime
• “Tired but wired” feeling
• Difficulty falling asleep, even when exhausted

Functional Solution:
Support healthy adrenal function with stress-reducing habits like meditation, grounding, and a consistent sleep-wake cycle. Nutrients like magnesium glycinate, phosphatidylserine, and adaptogenic herbs (ashwagandha, rhodiola) can help rebalance your cortisol rhythm.

3. Mineral Deficiencies (Especially Magnesium and Zinc)

Your body requires a delicate balance of minerals for neurotransmitter production, muscle relaxation, and hormone regulation. Magnesium is often called “nature’s tranquilizer” and plays a key role in calming the nervous system.

Signs this may be your issue:

• Muscle cramps or restless legs
• Teeth grinding
• Trouble relaxing or falling asleep

Functional Solution:
Incorporate magnesium-rich foods (dark leafy greens, pumpkin seeds, avocado) and consider supplements like magnesium glycinate or magnesium L-threonate at night. A functional medicine provider can also test your levels of magnesium, zinc, and other electrolytes to guide treatment.

4. Hormonal Imbalances

Women especially are vulnerable to sleep disturbances during times of hormonal change—menopause, perimenopause, PMS, or postpartum. Fluctuations in estrogen and progesterone can disrupt melatonin production and alter temperature regulation.

Signs this may be your issue:

• Night sweats or hot flashes
• Insomnia around your period
• Waking up too early

Functional Solution:
Functional lab testing can uncover imbalances in estrogen, progesterone, and other hormones like thyroid or cortisol. Support your hormonal health with flaxseed, cruciferous vegetables, healthy fats, and targeted herbs like chasteberry (Vitex) or black cohosh.

5. Poor Gut Health and the Microbiome

Your gut and brain are deeply connected via the gut-brain axis. About 90% of your body’s serotonin (a precursor to melatonin) is produced in the gut. Disruption of the microbiome, chronic bloating, or undiagnosed food sensitivities can lead to neuroinflammation and poor sleep.

Signs this may be your issue:

• Bloating, gas, or constipation
• Anxiety or brain fog
• Waking up tired despite "sleeping"

Functional Solution:
A comprehensive gut healing protocol—including probiotics, fermented foods, digestive enzymes, and elimination of trigger foods—can dramatically improve sleep quality. Consider testing for SIBO, leaky gut, or candida overgrowth.

6. Sleep Apnea or Oxygen Desaturation

Undiagnosed obstructive sleep apnea or even mild nighttime breathing issues can prevent deep, restorative sleep by causing frequent micro-awakenings due to oxygen drops. Many people don’t realize they stop breathing multiple times per night.

Signs this may be your issue:

• Snoring or gasping at night
• Waking up with dry mouth or headache
• Feeling exhausted despite “8 hours” in bed

Functional Solution:
A sleep study can confirm if sleep apnea is an issue. In the meantime, reducing inflammation, improving nasal breathing (mouth taping or nasal strips), and losing weight can help reduce symptoms. Functional medicine also addresses root causes like sinus issues or lymphatic congestion.

7. Environmental and Lifestyle Factors

Your external environment and evening habits play a major role in preparing your brain for rest. Overexposure to blue light, working late into the evening, or having an inconsistent bedtime can delay melatonin release.

Signs this may be your issue:

• Staying up past 11 p.m. regularly
• Scrolling on your phone or watching TV in bed
• Falling asleep with lights or noise on

Functional Solution:
Start a calming sleep hygiene routine:

• Dim lights after sunset
• Avoid screens 60–90 minutes before bed or wear blue-light-blocking glasses
• Use blackout curtains and a white noise machine
• Try calming teas like chamomile or passionflower

The Functional Medicine Approach to Insomnia

Unlike conventional approaches that rely on sleeping pills, functional medicine aims to understand and correct the underlying imbalances interfering with your sleep.

At Sheen Vein & Cosmetics, we take a comprehensive look at:

• Cortisol and melatonin rhythm testing
• Hormone panels (thyroid, estrogen, progesterone)
• Micronutrient levels (magnesium, zinc, B-vitamins)
• Gut health and food sensitivity testing
• Oxygen and sleep apnea evaluations
• Lifestyle and environmental exposures

With this root-cause data, we develop a personalized plan that addresses your unique sleep barriers through nutrition, natural therapies, supplementation, and lifestyle optimization.

Conclusion: Sleep Is a Window Into Your Health

If you’re struggling to sleep, your body is trying to tell you something.

Whether the issue is blood sugar, stress, hormones, or gut health, insomnia is a symptom—not a diagnosis. You don’t have to settle for band-aid solutions or years of restless nights. The functional medicine model offers a roadmap to restore your sleep by healing your body from the inside out.
