Sleep Disorders
Sleep disorders affect millions and have profound effects on health. Huberman discusses the most common issues, their mechanisms, and evidence-based approaches to treatment.
Common Sleep Disorders
| Disorder | Characteristics |
|---|---|
| Insomnia | Difficulty falling/staying asleep |
| Sleep apnea | Breathing interruptions |
| Delayed sleep phase | Clock runs late |
| Restless legs | Urge to move legs |
| Narcolepsy | Excessive daytime sleepiness, sudden sleep |
Insomnia
The most common sleep complaint.
Types
| Type | Pattern |
|---|---|
| Sleep onset | Difficulty falling asleep |
| Sleep maintenance | Waking during night |
| Early morning awakening | Waking too early |
| Mixed | Combination |
Causes
- Psychological: Anxiety, depression, stress
- Behavioral: Poor sleep habits, irregular schedule
- Medical: Pain, medications, other conditions
- Circadian: Misalignment of body clock
Evidence-Based Treatment
CBT-I (Cognitive Behavioral Therapy for Insomnia) is first-line:
| Component | Description |
|---|---|
| Sleep restriction | Match time in bed to actual sleep |
| Stimulus control | Bed only for sleep |
| Cognitive restructuring | Address sleep-related thoughts |
| Sleep hygiene | Environmental and behavioral factors |
CBT-I is more effective long-term than sleep medications.
Sleep Apnea
Breathing stops repeatedly during sleep.
Types
- Obstructive: Airway physically blocked
- Central: Brain doesn’t signal breathing
- Complex: Combination
Signs
- Snoring (especially with pauses)
- Gasping/choking during sleep
- Daytime sleepiness despite adequate time in bed
- Morning headaches
- Partner observes breathing stops
Why It Matters
Untreated sleep apnea causes:
- Cardiovascular disease
- Hypertension
- Cognitive impairment
- Metabolic dysfunction
- Shortened lifespan
Treatment
- CPAP: Gold standard, continuous positive airway pressure
- Oral appliances: For mild to moderate
- Weight loss: If overweight (often curative)
- Positional therapy: If worse on back
- Surgery: In select cases
If you snore heavily and are tired despite sleeping, get evaluated.
Delayed Sleep Phase
Clock runs late (natural “night owl” taken to extreme).
Characteristics
- Can’t fall asleep until very late (2-4 AM)
- If allowed to sleep late, sleep is normal
- Forced early wake creates chronic deprivation
- Common in adolescents
Treatment
- Morning light exposure
- Evening light avoidance
- Gradual schedule advancement
- Low-dose melatonin (timed correctly)
Restless Legs Syndrome
Uncomfortable sensations with urge to move legs.
Characteristics
- Worse at rest and evening/night
- Relieved by movement
- Disrupts sleep onset
- Associated with iron deficiency
Approach
- Check iron/ferritin levels
- Reduce caffeine and alcohol
- Medications if severe (dopamine agonists, gabapentin)
General Sleep Hygiene
Foundation for any sleep issue:
| Practice | Rationale |
|---|---|
| Consistent schedule | Stabilizes circadian rhythm |
| Cool, dark room | Optimal sleep environment |
| No screens before bed | Reduces light exposure |
| Limit caffeine | Especially afternoon/evening |
| Regular exercise | But not too late |
| Avoid alcohol | Disrupts sleep architecture |
When to Seek Help
Consult a professional if:
- Problems persist despite good sleep hygiene
- Daytime function is impaired
- Partner observes breathing issues
- Excessive daytime sleepiness
- Unusual behaviors during sleep
