From the Guidelines
Biphasic sleep with a 4-hour core sleep period plus a 90-minute nap is not the most recommended approach for someone with ADHD working consecutive night shifts, as a consolidated 6-7 hour sleep period during the day is generally more beneficial for cognitive function and attention regulation. For emergency medicine residents working consecutive night shifts, maintaining a consistent sleep schedule is crucial, and a consolidated sleep period can help reduce sleep disruptions that can worsen ADHD symptoms 1. If you do try the split sleep approach, it is essential to maintain strict consistency with your sleep schedule, sleeping immediately after your shift (e.g., 8am-12pm) with your nap timed approximately 6-8 hours later (around 6-7pm before your shift). Some key considerations for implementing this schedule include:
- Creating a dark, quiet sleeping environment using blackout curtains, eye masks, and earplugs
- Limiting screen exposure before sleep periods
- Avoiding caffeine at least 6 hours before your planned sleep
- Discussing with your physician about adjusting your ADHD medication timing to align with your work hours, typically taking stimulant medication about 1-2 hours before your shift begins It is also important to note that the split sleep schedule provides less total deep sleep than a consolidated sleep period, which is particularly important for cognitive function and attention regulation in ADHD 1.
From the Research
Biphasic Sleep Pattern for Emergency Medicine Resident with ADHD
The biphasic sleep pattern, also known as split sleep, involves taking a 4-hour core sleep and a 90-min nap. To determine if this sleep pattern would work for an emergency medicine resident with ADHD working 6 straight night shifts, we need to consider the following factors:
- The resident's ADHD condition and its impact on sleep patterns
- The effects of stimulant medications on sleep
- The feasibility of adapting to a biphasic sleep pattern during night shifts
ADHD and Sleep Patterns
Studies have shown that individuals with ADHD often experience sleep disturbances, including difficulty falling asleep, staying asleep, and maintaining a consistent sleep schedule 2. However, there is no direct evidence to suggest that a biphasic sleep pattern would be beneficial or detrimental for individuals with ADHD.
Stimulant Medications and Sleep
Stimulant medications, such as amphetamine and methylphenidate, are commonly used to treat ADHD. These medications can interfere with sleep patterns, making it difficult to fall asleep or stay asleep 3, 2. However, some studies suggest that taking stimulant medications in the evening, such as delayed-release and extended-release methylphenidate, can help improve sleep quality in individuals with ADHD 4.
Feasibility of Biphasic Sleep Pattern during Night Shifts
There is no direct evidence to support the use of a biphasic sleep pattern for emergency medicine residents working night shifts. However, some studies suggest that taking naps during night shifts can help improve alertness and reduce fatigue 5. It is essential to note that adapting to a biphasic sleep pattern during night shifts may be challenging, and individual results may vary.
Key Considerations
When considering a biphasic sleep pattern, it is crucial to weigh the potential benefits against the potential drawbacks, including:
- Potential interference with stimulant medication schedules
- Difficulty adapting to a new sleep schedule during night shifts
- Impact on overall sleep quality and duration
- Potential effects on ADHD symptoms and medication efficacy
