Writing a To-Do List Before Bed Can Help You Fall Asleep Faster

For many people, the moment they lie down to sleep is when their mental workload peaks. Concerns about upcoming meetings, unanswered emails, and unresolved chores often interrupt the transition into rest. Rather than wrestling with these thoughts in bed, experts recommend a simple intervention: write out tomorrow’s to-do list earlier in the evening.

“One of the most common complaints I hear from patients with insomnia is that they are exhausted, but their mind will not stop,” said Dr. M. Taruj Ali, medical director of sleep medicine at Mary Washington Healthcare in Fredericksburg, Virginia. He noted that patients frequently describe a continuous internal catalog of pending tasks. Transferring these thoughts onto paper can signal to the brain that it is safe to release them for the night.

Timing is a critical component of this strategy. Professionals advise against treating list-making as a last-minute bedtime ritual. Instead, individuals should dedicate five to ten minutes to the exercise while winding down from daytime responsibilities, such as finishing work or completing household chores. Sari Chait, a clinical psychologist based in Dedham, Massachusetts, explained that moving tasks from the mind to paper lessens the cognitive pressure to keep rehearsing them. If a new task arises later, it can be quickly jotted down on a bedside notepad without escalating into a full planning session.

Research supports the efficacy of this practice. A 2018 study involving 57 adults aged 18 to 30 found that participants who spent five minutes at bedtime writing about upcoming tasks fell asleep, on average, nine minutes faster than those who listed past accomplishments. The study also indicated that more detailed lists correlated with quicker sleep onset. However, researchers cautioned that the results may not apply to individuals with clinical insomnia, as the study focused on healthy young adults in a controlled lab setting.

The underlying mechanism is known as cognitive offloading. Stephanie High, a psychology doctoral candidate in Spokane, Washington, compared unresolved tasks to background apps on a smartphone that drain battery and memory. Writing a task down allows the brain to acknowledge its importance while conceding that immediate action is unnecessary.

Beyond sleep benefits, the habit establishes a psychological boundary between professional and personal time. Alexis Haselberger, a productivity coach in San Francisco, stated that planning the day ahead helps individuals mentally disconnect from work, preventing them from ruminating on responsibilities while engaging with family or leisure activities. Additionally, starting the morning with a predefined list eliminates the delay of deciding what to tackle first.

To create an effective list, experts suggest beginning with a comprehensive “brain dump” to capture all outstanding items, followed by selecting three key priorities for the next day. These priorities should be cross-referenced with existing calendar commitments to ensure feasibility. Specificity is essential; vague entries like “prep for meeting” leave the mind searching for details, whereas specific instructions such as “email Q3 deck” close the cognitive loop.

The format need not be elaborate. Whether using a physical notebook or a digital notes app, the method should be sustainable. Chait emphasized that the list does not need to be aesthetically pleasing to be effective.

Finally, the exercise should not become a source of stress. If list-making triggers anxiety or feels like a record of failures, it defeats its purpose. High warned that focusing on unresolved problems can activate the nervous system right when relaxation is needed. Instead, the goal is to capture necessary reminders and then disengage. Treating the practice as a flexible experiment rather than a rigid obligation can help individuals determine if it genuinely reduces nighttime rumination and improves morning focus.
