Insomnia

The frustrating inability to sleep. Insomnia—difficulty falling asleep, staying asleep, or waking too early—affects about 30% of adults. It's rarely a standalone problem. Usually, it's a symptom pointing to underlying issues: circadian disruption, stress, blood sugar swings, nutrient deficiencies, or a hyperactive nervous system.

Insomnia Patterns

Onset Insomnia

Can't fall asleep. Lying awake for hours. Racing mind. Often anxiety or cortisol related.

Early Morning

Wake too early, can't return to sleep. Often depression or cortisol rhythm problems.

Why You Can't Sleep

Nervous System Issues

  • Hyperarousal: Stuck in fight-or-flight
  • High cortisol at night: Should be lowest then
  • Low GABA: Calming neurotransmitter insufficient
  • Anxiety/racing thoughts: Mind won't stop

Circadian Disruption

  • Blue light at night: Suppresses melatonin
  • No morning light: Clock not set properly
  • Irregular schedule: Body doesn't know when to sleep
  • Shift work: Fighting biology

Contributing Factors

Blood Sugar Swings

Low blood sugar triggers cortisol/adrenaline at 3am. Causes classic middle-of-night waking.

Magnesium Deficiency

Natural relaxant. Most people are low. Activates parasympathetic nervous system.

Caffeine

Half-life 5-7 hours. Afternoon coffee affects sleep. Blocks adenosine (sleepiness signal).

Alcohol

Sedates initially but fragments sleep. Reduces REM. Causes early waking as it metabolizes.

Histamine

Histamine is stimulating. High histamine people often have insomnia. DAO issues.

Sleep Apnea

Breathing stops repeatedly. Wakes you without knowing. Feels like insomnia. Get tested.

Sleep Solutions

Morning Sunlight

10+ minutes bright light within hour of waking. Sets circadian clock. Helps melatonin timing.

Block Blue Light

Blue-blocking glasses after sunset. Dim lights. No screens 1-2 hours before bed.

Magnesium Glycinate

300-400mg before bed. Calms nervous system. Most effective form for sleep.

Blood Sugar Stability

Protein before bed prevents 3am waking. Avoid sugar and alcohol at night.

Nervous System Calming

Evening routine to downshift. Warm bath, stretching, reading. Signal safety to body.

CBT-I

Cognitive behavioral therapy for insomnia. Most effective long-term treatment. Addresses conditioning.
