How does this tool calculate wake times?

The tool uses a standardized 90-minute sleep cycle model and accounts for sleep onset latency to suggest times when you are most likely to be in a light sleep stage.

What is sleep inertia?

Sleep inertia is the feeling of grogginess or disorientation experienced immediately after waking up, especially if woken during a deep sleep stage.

Can I compare different sleep schedules?

Yes, you can use the `compare_wake_options` tool to evaluate two different scenarios and see which one provides better sleep quality and less grogginess.

This MCP server helps you align your wake times with natural biological sleep cycles to minimize sleep inertia. By using a 90-minute sleep cycle model, you can determine the best moments to wake up to feel most alert. Use calculate_wake_windows to find a range of ideal times, assess_grogginess_risk to check how disoriented you might feel, get_optimal_alarm_setting for a single recommended alarm, or compare_wake_options to weigh different sleep scenarios.
