Shift Work Sleep Disorder (SWSD)
Difficulty sleeping or excessive daytime sleepiness caused by working night, early morning, or rotating shifts that conflict with your natural sleep rhythm.
- Insomnia during scheduled sleep times
- Excessive sleepiness during work hours
- Poor concentration and reduced work performance
- Increased risk of accidents and injuries
- Difficulty maintaining social relationships
Shift work disrupts your circadian rhythm for 24–72 hours or longer. We help you manage sleep through light exposure timing, melatonin strategies, and behavioral techniques tailored to your specific shift schedule.
Jet Lag (Desynchronosis)
Temporary misalignment of your internal clock after rapid travel across time zones, causing fatigue, insomnia, and reduced daytime functioning.
- Difficulty sleeping at new destination times
- Daytime fatigue and brain fog
- Irritability and mood changes
- Digestive issues
- Reduced alertness and decision-making
Jet lag typically resolves in days to weeks depending on time zone difference and direction of travel. We provide rapid resynchronization protocols using light timing, melatonin, and behavioral strategies to minimize disruption to your travel and work.
Delayed Sleep Phase Syndrome (DSPS)
A chronic condition where your internal clock runs on a significantly later schedule than conventional sleep times, making it extremely difficult to fall asleep at conventional times.
- Unable to fall asleep before 2–6 AM or later
- Extreme difficulty waking before 9–11 AM
- Sleep quality is normal if schedule is maintained
- Difficulty meeting conventional work or school schedules
- Often misdiagnosed as insomnia
DSPS is most common in adolescents and young adults. We use morning bright light therapy, melatonin timing, and gradual schedule adjustment to shift your circadian rhythm earlier, helping you align with conventional schedules.
Advanced Sleep Phase Syndrome (ASPS)
A condition where your internal clock runs significantly earlier than desired, causing you to fall asleep and wake up much earlier than you'd like.
- Fall asleep uncontrollably between 6–8 PM
- Wake between 2–4 AM unable to return to sleep
- Sleep quality is normal if schedule is maintained
- Difficulty participating in evening activities
- More common in older adults
ASPS is most common in older adults and can significantly impact social and work life. We use evening bright light exposure, melatonin timing, and behavioral strategies to shift your circadian rhythm later.
Irregular Sleep-Wake Pattern
A disrupted pattern with no clear circadian rhythm, often involving multiple fragmented sleep episodes throughout a 24-hour period without a consistent schedule.
- Multiple naps or sleep episodes daily
- No consistent sleep schedule
- Fragmented, poor-quality sleep
- Chronic daytime fatigue despite long sleep duration
- Often associated with neurological or medical conditions
Irregular patterns can result from dementia, neurodevelopmental conditions, or lifestyle factors. We establish structured sleep-wake schedules through light exposure, behavioral consistency, and environmental modification to restore circadian organization.
Non-24-Hour Sleep-Wake Disorder (N24)
A rare condition where your internal clock runs longer than 24 hours, causing your sleep schedule to progressively drift later each day, cycling through all hours of the day and night over weeks.
- Progressive delay in sleep and wake times daily
- Cyclical periods of insomnia and excessive sleep
- Difficulty maintaining consistent schedule
- Often seen in blind individuals
- Can cause significant lifestyle disruption
N24 requires specialized approaches including consistent light exposure, melatonin therapy, and behavioral strategies. We work with you to establish anchoring routines and consider coordination with medical specialists.
