Sleep disorders affect approximately 16 million adults in the UK, with insomnia being the most common sleep problem, according to The Sleep Council. The NHS estimates that poor sleep costs the UK economy £40 billion annually through reduced productivity, increased healthcare costs, and workplace accidents. Understanding sleep disorders and implementing effective sleep hygiene strategies is crucial for both physical and mental health, as quality sleep affects virtually every aspect of human functioning.
Understanding Sleep: The Science of Rest
Sleep is a naturally recurring state of mind and body characterisation by altered consciousness, reduced sensory activity, and relative inactivity of nearly all voluntary muscles. The British Sleep Society describes sleep as essential for physical health, cognitive function, emotional regulation, and overall wellbeing.
Sleep Architecture:
Non-REM Sleep (75% of sleep time):
Stage 1 (Light Sleep):
- Transition between wakefulness and sleep
- Lasts 5-10 minutes
- Easy to wake from
- Muscle activity slows down
Stage 2 (True Sleep):
- Comprises 45-55% of total sleep
- Body temperature drops
- Heart rate and breathing slow
- Brain waves show sleep spindles and K-complexes
Stage 3 (Deep Sleep):
- Also called slow-wave sleep or delta sleep
- Most restorative sleep stage
- Physical repair and growth occur
- Immune system strengthening
- Memory consolidation
- Difficult to wake from
REM Sleep (25% of sleep time):
- Rapid Eye Movement sleep
- Most vivid dreams occur
- Brain activity similar to wakefulness
- Important for cognitive function and memory
- Emotional regulation and processing
- Muscle atonia (temporary paralysis)
Sleep Cycles:
Normal Sleep Pattern:
- 4-6 complete cycles per night
- Each cycle lasts 90-120 minutes
- More deep sleep in early cycles
- More REM sleep in later cycles
- Brief awakenings between cycles are normal
Common Sleep Disorders
Sleep disorders encompass a wide range of conditions that affect sleep quality, timing, or duration. The International Classification of Sleep Disorders recognises over 80 different sleep disorders grouped into several categories.
Insomnia Disorders:
Chronic Insomnia:
The most common sleep disorder affecting 10-15% of adults:
- Difficulty falling asleep: Taking more than 30 minutes to fall asleep
- Difficulty staying asleep: Frequent awakenings with difficulty returning to sleep
- Early morning awakening: Waking too early and unable to return to sleep
- Non-restorative sleep: Not feeling refreshed despite adequate sleep time
- Occurs at least 3 nights per week for 3 months or longer
Acute Insomnia:
Short-term sleep difficulty:
- Lasts less than 3 months
- Often related to specific stressors
- Work, relationship, or health concerns
- Travel and jet lag
- Usually resolves when trigger is addressed
Sleep-Related Breathing Disorders:
Obstructive Sleep Apnoea (OSA):
Affects 2-4% of adults, often undiagnosed:
- Mechanism: Upper airway collapse during sleep
- Symptoms: Loud snoring, breathing pauses, gasping, morning headaches
- Risk factors: Obesity, male gender, advancing age, neck circumference >17 inches (men), >16 inches (women)
- Health consequences: Hypertension, cardiovascular disease, diabetes, cognitive impairment
Central Sleep Apnoea:
Less common than OSA:
- Mechanism: Brain fails to send signals to breathing muscles
- Risk factors: Heart failure, stroke, brainstem disorders
- Symptoms: Similar to OSA but may have less snoring
- Treatment: Often requires specialised medical management
Circadian Rhythm Sleep-Wake Disorders:
Delayed Sleep-Wake Phase Disorder:
Common in adolescents and young adults:
- Pattern: Cannot fall asleep until very late (often 2-6 AM)
- Morning difficulties: Extreme difficulty waking for school or work
- Weekend pattern: Can sleep normally if allowed to follow natural schedule
- Impact: School/work performance, social functioning
Advanced Sleep-Wake Phase Disorder:
More common in older adults:
- Pattern: Fall asleep very early (6-8 PM), wake very early (2-4 AM)
- Impact: Social functioning, evening activities
- Often genetic: Family history common
Shift Work Sleep Disorder:
Affects 10-40% of shift workers:
- Cause: Work schedule conflicts with natural circadian rhythms
