Establishing and maintaining a healthy sleep routine proves difficult for most people.
The majority of adults need between seven and nine hoursof sleep each night. However, 62 percentof people say they face trouble maintaining their sleep schedule, while 35 percent of US adults say they regularly get less than seven hours of sleep.
Moreover, 40percent of peopleunintentionally fall asleep during the day regardless of how much sleep they got the night before.
If you find yourself waking up tired even after eight hours of sleep, sleep inertia may be to blame.
Sleep Inertia 101
Sleep inertia is a term used to describe feelings of confusion, disorientation, grogginess, and extreme tiredness immediately after waking.
This feeling usually lasts for 15 minutes to an hour, but some people feel the effects of sleep inertia for several hours upon waking up.
The exact biological cause for sleep inertia is currently unknown, but we have a few theories to explain this phenomenon.
Scientists believethat sleep inertia is triggered as a protective mechanism that helps us stay asleep throughout the night rather than waking up at every little disturbance.
Regardless of the cause, sleep inertia can easily become dangerous. In people with unpredictable work schedules, it impacts worker safetyand well-being.
Hazards of Sleep Inertia
Sleep inertia impacts cognitive ability, focus, and even our visual concentration.
For these reasons, it can quickly become dangerous. Moreover, it manifests as intense sleepiness, brain fog, delayed reaction times, and an undeniable urge to go back to sleep.
Within the first hour of waking, our decision-making skills drop by over 50 percent.
Therefore, work-related tasks or risky tasks like early morning driving can quickly turn hazardous due to sleep inertia.
