Understanding Sleep Inertia

Sleep inertia, the post-awakening sleepiness and grogginess, can hinder your productivity and focus. This phenomenon arises from a temporary reduction in task efficiency due to a portion of your body still being in a sleep state. Learn how Circular's smart alarm can combat sleep inertia and elevate your mornings to new levels of energy and motivation.

Sleep inertia can last anywhere from 1 minute to over 3 hours, and its severity peaks when waking up from REM and deep sleep stages. Its effects can be observed in:

• Drowsy driving
• Low productivity in the first part of the day
• Reduction in memory ability
• Low performance and response time on tasks, loss of concentration
• Impairment of the capability to make decisions
  ‍

Several factors influence sleep inertia, including genetics, sleep efficiency, and the sleep stage from which you awaken.

Of course, sleep inertia is dependent on several factors, such as your genetics, sleep efficiency, how long you have been asleep and the sleep stage in which you woke up.

Optimize Your Wake-Up

Each sleep stage serves vital physiological and neurological functions crucial for overall health. Waking up at the end of a sleep stage, specifically during light sleep, can leave you feeling naturally refreshed and alert. Circular's smart alarm is the key to achieving this.
