The ADHD-Sleep Paradox: Understanding Circadian Rhythm Disruption and Effective Sleep Strategies

Dr. Tracey Marks discusses the prevalent issue of sleep problems among individuals with ADHD, highlighting that the disorder itself alters the body's circadian rhythm. This biological clock, which governs not only sleep but also hunger, body temperature, emotional regulation, and executive functions like working memory and time management, becomes misaligned, leading to what some term "social jetlag." Common sleep difficulties include trouble initiating sleep, restless sleep with frequent awakenings, and significant morning grogginess, even after sufficient sleep, often due to falling into a deep sleep during the early morning hours.

A core problem for those with ADHD is "eveningness" or a delayed phase sleep problem, characterized by increased energy and a desire to engage in activities later in the evening, making it natural to delay bedtime. Unlike individuals without ADHD, whose bodies provide clear signals of drowsiness, those with ADHD experience much subtler cues, easily missed when engrossed in stimulating activities. Furthermore, the podcast details a critical bidirectional relationship between ADHD medications—both stimulants (amphetamines, methylphenidate) and non-stimulants (atomoxetine, viloxazine/Qelbree)—and sleep. These medications can delay sleep onset and increase nighttime awakenings, while insufficient sleep, in turn, diminishes the medications' effectiveness, potentially leading to a perceived need for higher doses.

To address these challenges, Dr. Marks advocates for a combination of behavioral interventions and, temporarily, sleep-enhancing medications. Practical strategies include establishing a strict bedtime schedule with alarms to initiate a wind-down routine, potentially using two alarms for those who need a warning. Behavioral techniques encompass wearing blue light blocking glasses two hours before bed, engaging in relaxing activities like listening to music, meditation (progressive muscle relaxation, body scans), tapping for anxiety, meditative coloring, or a warm foot bath (timed two hours before bed to allow for body cooling). Regular daytime exercise is also emphasized for its role in promoting natural tiredness and fostering brain health through brain-derived neurotropic factor.

The broader implications of this sleep-ADHD paradox extend beyond just a good night's rest, impacting overall mental health, cognitive function, and the efficacy of ADHD treatment. By understanding the unique ways ADHD affects the circadian rhythm and sleep signals, individuals can implement targeted strategies to improve sleep hygiene and quality. While sleep medications can offer temporary relief for entrainment or recovery from sleep deficits, their intermittent use is recommended due to tolerance development. Ultimately, a holistic approach combining structured routines, mindful relaxation, and physical activity is crucial for managing ADHD-related sleep disturbances and enhancing daily functioning and well-being.

Research is showing that the disorder itself changes your circadian rhythm.

Your circadian rhythm is your biological clock that controls many of your body's functions.

Some people refer to this misalignment to your environment as social jetlag.

People with ADHD have a proneness to what's called eveningness or a delayed phase sleep problem.

with ADHD, your body signaling is a lot more subtle. It's like your body says, "I can go to bed if you let me. I'm ready when you are, but if you're not, I'll just sit here and wait."

not getting enough sleep decreases the effectiveness of the medication

Sleep medications are a temporary solution that can help entrain your body to fall asleep at a certain time when you don't have a routine.

Regularly wearing blue light blocking glasses two hours before bedtime, then the hour before bed you do something relaxing like listening to music, listening to a meditation like a progressive muscle relaxation or a body scan.

Exercise during the day helps your body feel more tired at night, and it helps create new nerve connections in the brain through brain-derived neurotropic factor.
