Circadian Rhythm Sleep Care Serving Palo Alto

Examples include:

• A sleep period that occurs much later than desired
• Sleepiness and waking that occur much earlier than desired
• Sleep timing that changes substantially from day to day
• Difficulty sleeping or staying alert because of night or rotating work
• Persistent misalignment after travel or a major schedule change

Preference for late or early hours alone does not establish a disorder. The pattern must be understood in relation to sleep opportunity, obligations, symptoms, and functioning.

Evaluation may include a detailed sleep history, sleep diary, work and school schedule, light exposure, medication and substance use, medical and psychiatric history, and prior attempts to change the schedule. Wearable or other objective information may sometimes supplement the history but does not replace clinical interpretation.

Insomnia, insufficient sleep, depression, bipolar-spectrum conditions, ADHD, substance use, and other sleep disorders may resemble or complicate a circadian problem.

An individualized plan may involve:

• Gradual changes to sleep and wake timing
• Consistent wake times and daily routines
• Timed exposure to or avoidance of light
• Carefully timed melatonin when appropriate
• Behavioral strategies that support adherence
• Planning around work, school, caregiving, travel, or social demands
• Treatment of co-occurring insomnia or another condition

Timing matters. Light or melatonin used at the wrong time can shift the sleep schedule in an unintended direction, so the clock time and dose are set for the individual rather than from a general rule.

No. Light exposure may require added caution for people with certain eye conditions, light-sensitive medications, migraine, or bipolar-spectrum illness. Melatonin products vary, may interact with medications, and can cause adverse effects. Patients should discuss individual risks and timing with an appropriate clinician.

Temporary jet lag is not the same as a persistent circadian condition. Shift workers may have limited control over scheduling, and not every occupational demand can be corrected clinically. A plan may focus on sleep opportunity, strategic light, timing, alertness, and safety, but cannot guarantee adaptation to rotating or overnight work.
